How do insects help a plant to reproduce

Animals can be very important to plant reproduction in two ways—spreading pollen and spreading seeds. Pollen contains a plant’s sperm. Some pollen just blows around in the wind, but this is very wasteful because a lot of that pollen will never fall on the female part of another plant of the same species. Many plants “pay” animals to deliver their pollen. They may provide sugar (nectar) to coax animals into visiting their flowers and pick up pollen. They only give the animal a little, so the animal has to go to another flower, where the pollen can fertilize another plant. Honeybees, hummingbirds, and some bats do this. Other plants attract pollinators in different ways. One plant attracts flies by smelling like dead animals. Another looks like a female insect and attracts male insects.

Fruit is another type of payment. An animal may eat a fruit in one area, by defecate (poop) in another place, so that seeds get carried to new areas with the bonus of a dab of fertilizer and moisture. A large animal may carry a larger fruit far away to eat it, the drop the seed. Some animals, like squirrels, collect nuts and hide them. They don’t find every nut they hide, so some will sprout in new places. Relationships where individuals of both species benefit are called mutualisms. Most fruit only becomes edible when the seed inside is mature. Why would this benefit the plant?

Thanks for asking,

Animals help plants by pollinating them, and be helping to disperse seeds.The droppings of animals also fertilize plants.

Plants have different reproductive manners. For instance, flowering plants rely on insects to harvest pollen. One bee will travel to many different flowers in one day. When the bee collects the pollen in the flower from the stamen, it gets some of the pollen on it’s body and legs; this pollen will be transferred to the next flower it visits, as the bee must pass by the pistil. This movement of pollen from one flower to another allows the plant to reproduce. Another example are fruit bearing plants – anything from apples to berries to cucumbers – essentially any food with a seed inside. When an animal eats these seeds, they are not processed in the body, so when they excrete them, the seeds are then in a new location, and can start growing. The transport of seeds from one location to another allows new plants to start without taking away resources from the original plant. Conifer trees (pine, spruce, fur, etc.) use their pinecones – there are seeds in there that can be eaten or distributed by mice and other animals. On a whole different note, there are some carnivorous plants, such as the Venus fly trap, or the Pitcher plant. These plants actually eat insects and small animals! It is important to understand as well that some plants are dependent on one animal to pollenate it each year, and if that animal goes extinct or has to move because of environmental conditions, the plant will die.

Animals help plant reproduction by helping spread plant pollen and seeds. For example, bees pollinate flowers, which is vital to spreading genes and reproducing. As a point of interest, insects actually co-evolved with flowering plants, which means that they evolved together over time, in a relationship that benefitted both the plants and the insects, and with a speed and success that would likely not have been possible without the relationship. As another example, many animals eat fruits, and then travel a long distance before they poop out the seeds. The travelling animal helps spread the seeds to far off places, and the manure acts as a fertilizer to help the seeds grow.

One way animals can help plant reproduction is by directly fertilizing them. This can be seen with insects that pollinate flowers. As they go from plant to plant, pollen grains stick to them and are deposited into the next flower. Animals can also help plant reproduction by dispersing seeds around in different areas. Seeds can stick to fur or be intentionally moved, such as when squirrels or birds pick them up and drop or bury them. Animals that eat seeds also disperse the seeds when the poop them out. Some plants have even evolved to where they can only propagate with the help of animals. A unique example of this is in the rainforests of Australia. There is a tree that produces egg- sized, purple fruit with a pit (seed) in the center. The seed cannot germinate unless it passes through the digestive tract of a large, primitive bird called a Cassowary.

Animals spread seeds around. This is called seed dispersal. By helping seeds get away from the parent plant and into new, uncolonized habitats, they increase not only the seeds’ propensity to survive, but also allow plants to colonize new areas. In addition, the caching behavior of many rodents and some birds (caching seeds to eat them later) plants seeds so that they have an easier time sprouting.

Pollinating insects play a key role in the reproduction of plant species. Without them, the reproduction of flowers would be impaired, which would also prevent the formation of fruits and seeds, and would considerably limit the diet with all the nutritional diversity it currently provides us with.

What is pollination?

Apart from a very small proportion of plants that are hermaphroditic and can self-fertilize, for a flower to become a fruit it must be fertilized, i.e. the pollen (male gamete) must reach the pistil, the ovaries, the female organ.

The wind can take care of this task when the pollen grains are very light, but the vast majority of plants need external help from pollinating insects.

The transport of pollen from one flower to the egg of another is called pollination, it is called reproduction. In order for the insect to be attracted to the flower, the flower secretes a sweet nectar which the insect eats by rubbing itself with the stamens whose pollen is deposited on the insect. While going to forage another flower, it will still rub itself, leaving a little pollen that it carries, on the female organ of this second flower.

Who are the pollinating insects?

Under the general name of “pollinating insects” hides a small but discreet but very valiant world that ensures a vital function on our planet: pollination.

By their movements on flowers, insects transport pollen from one to the other and thus ensure their fertilization.

Reproduction is then possible and the flowers thus pollinated will be able to produce seeds. Note that these insects participate in the fertilization of 80% of plants which without them could not reproduce, that is to say their importance!

The main pollinating insects are bees, especially “Apis domestica” our common bee, but also all the many species of the genus.

Distant cousins, bumblebees are very active, especially at the very beginning of the season and even in winter, because they tolerate the cold better than bees and ensure early pollination. Osmies and wasps also play an important role, just as much as xylocopes, those robust insects with bluish-black reflections roaring in our orchards!

Some flies, such as syrphes, are also excellent pollinators, the latter having the particularity of laying larvae directly on plants invaded by aphids so that they can feed on them; an exemplary gardener’s helper!

Another insect with a slender and light appearance: the butterfly. It dips its long proboscis in nectar and carries pollen on its hairy body, also participating in the reproduction of plants.

Beetles, like the golden ketone, also do their part in the renewal of the flora.

Threatened pollinating insects

The impact of human activity on nature is constantly reducing the populations of pollinating insects. Massive urbanization, intensive farming, especially monoculture, which implies the appearance of green deserts, the irrational use of pesticides and insecticides, the rarefaction of wild hedges and wasteland all contribute to this insidious disappearance of insect populations.

How to help pollinating insects?

To effectively help pollinating insects, simply let nature take its course. Creating a few fallow areas in the garden, planting a variety of hedges, installing a small water point and above all avoiding the use of phytosanitary products are all simple actions that are beneficial to insects.

You can go even further, by offering them refuges or by building a “hotel” made of recycled objects, which will be specially dedicated to them!

How does a bug hotel work?

Birds are no longer the only guests in the garden to benefit from nesting boxes: from now on, auxiliary insects are also entitled to hotels, i.e. shelters designed to attract them, keep them and offer them a home where they can reproduce. These “insect hotels” are multiplying all over France, both in private homes and in gardens open to the public.

Winter is a good time to install such shelters: since gardening work is becoming rarer, there is a little more time to tinker with a luxury hut for the winged inhabitants of the garden. You can also buy a ready-made shelter in garden centers or on the Internet. By installing the shed before the end of winter, you will have a better chance of seeing it occupied as early as March. The variety of insects that you can accommodate will increase over the months and years.

How to attract pollinating insects?

Caring for your plantation

Shrubs and perennials are planted after the great cold, from the end of winter in the South of France. In wet, soggy or frozen soils, wait until spring. Choose seedlings sold in buckets or containers.

Open a hole 2 to 3 times larger than the root ball: this is important because this volume of loosened soil encourages root development. Fertilizer is not necessary. Once in the ground these plants are resistant if you do not let them run out of water the first summer.

Honey plants in urban areas

If you grow vegetables on the balcony or terrace, welcome honey plants to increase yields. As space is limited, choose those that combine aesthetics, fragrance and flavor. Among aromatic plants, dill, coriander, sage, thyme and savory have attractive flowers.

For the pleasure, add purple lavender and nasturtiums or marigolds. In all cases, use well-drained soil for indoor or Mediterranean plants. Keep it cool, but never soggy.

Summary

Pollination can take several forms. Whether through animals, insects or wind. When flowers use the wind to disperse pollen, we speak of anemogamy. This type of pollination allows the plant to exchange pollen without being totally dependent on the foragers but it is much less efficient because the grains fly in all directions and only a tiny part will reach its target.

But the most common form of pollination is through a pollinating animal, which is called zoogamy. In this case, the pollinators are attracted to the nectar produced by the plants. When they come to forage, they will feed on the nectar and pollen. The pollen will then remain attached to the animal’s hair, feathers or skin.

It is while passing from flower to flower that the pollinators will disperse the pollen and thus allow the fertilization of these flowers. This is how plants reproduce!

Consequently, why are bees and other insects important for plants?

Pollination is needed for plants to reproduce, and so many plants depend on bees or other insects as pollinators. When a bee collects nectar and pollen from the flower of a plant, some pollen from the stamens—the male reproductive organ of the flower—sticks to the hairs of her body.

Similarly, how do bees help plants? Bees are perfectly adapted to pollinate, helping plants grow, breed and produce food. They do so by transferring pollen between flowering plants and so keep the cycle of life turning. The vast majority of plants we need for food rely on pollination, especially by bees: from almonds and vanilla and apples to squashes.

In this way, how do insects help plants grow?

They aerate the soil, pollinate blossoms, and control insect and plant pests. Many insects, especially beetles, are scavengers, feeding on dead animals and fallen trees, thereby recycling nutrients back into the soil. As decomposers, insects help create top soil, the nutrient-rich layer of soil that helps plants grow.

What is one benefit that pollinators give to flowering plants?

Plants benefit from pollinators because the movement of pollen allows them to reproduce by setting seeds. However, pollinators don’t know or care that the plant benefits. They pollinate to get nectar and/or pollen from flowers to meet their energy requirements and to produce offspring.

Plant reproduction comes in two types: sexual and asexual. Sexual reproduction is similar to human reproduction, in which male pollen and female ovarian germ cells fuse into a new organism that inherits the genes of both parents. The sexually reproductive part of a plant is the flower. Asexual reproduction involves vegetative reproduction through stems, roots, and leaves. Essentially, the parent plant regenerates itself by using one of its parts (roots, stems, or leaves).

Both sexual and asexual reproduction methods have their own advantages. In sexual reproduction, the newly formed plant is a combination of genes, giving it an advantage in adapting to changing environments. It can also avoid the transmission of certain diseases, as some genes are dominant and others recessive. Asexual reproduction is faster and perhaps the only way of reproducing in species that do not bear flowers. Since asexual reproduction is essentially the cloning of the parent plant, farmers can ensure that there is no genetic anomaly by selecting a healthy plant for reproduction.

Sexual Reproduction

Parts of a flower

How do insects help a plant to reproduce

Parts of a flower (Photo Credit: BlueRingMedia/ Shutterstock)

The flower consists of four whorls or parts (calyx, corolla, androecium, and gynoecium). The first whorl is the calyx, which contains the green sepals. The second whorl is the corolla which contains the petals. The petals are brightly colored to attract agents of pollination such as bees and other insects that help in reproduction. The petals also protect the two inner whorls that are directly involved in reproduction. The third whorl is the androecium – the male reproductive part of the plant. The innermost whorl is the gynoecium – the female reproductive part of a plant.

Androecium

The androecium contains a bundle of stamens composed of a tube called a filament and a swollen end called the anther. The anther contains pollen grains. Once matured, the pollen grains burst out to reach the female reproductive part of the flower.

Gynoecium

The gynoecium contains the pistil, which is composed of the tube (style) that reaches the ovary. The swollen tip of the style is the stigma that receives the pollen grains. In the ovary, there are the ovules, which turn into seeds.

Unisexual and bisexual flowers

Unisexual or monosexual flowers contain either of the reproductive parts (stamen or pistil). Papaya, corn, and cucumber are examples of unisexual flowers. The same plant can have both male and female unisexual flowers. Bisexual or complete flowers contain both the male and the female gametes – stamens and pistil. Examples of bisexual flowers are roses, petunias, and mustard plants.

Pollination

The transfer of pollen from the anther to the stigma of a flower is called pollination. During fertilization, the male and female germ cells of the pollen unite to form a zygote. A zygote then transforms into an embryo, which eventually becomes a seed. The seed then germinates into a new plant. There are two types of pollination – self-pollination, and cross-pollination.

How do insects help a plant to reproduce

There are two types of pollination (Photo Credit: Nasky/ Shutterstock)

Self-pollination: If the pollen grain from the anther lands on the stigma of the same flower or another flower of the same plant, it is called self-pollination.

Cross-pollination: If the pollen grain of an anther falls on the stigma of a flower of another plant but of the same species, this is called cross-pollination.

Pollinators: Birds, insects, animals, water, and wind are all called “agents of pollination”, as they help the plants reproduce. Wind and water carry the pollen grains to other plants. Birds and insects are attracted to the color and scent of the flower. As they flit from one flower to another, pollen grains get stuck in their bodies and are then transported to other flowers. Animals and birds eat the fruit and scatter the seeds, or the seeds remain undigested and are thus excreted from their body in full form.

Asexual Reproduction

Asexual reproduction is how we can clone the best plant of a species. The Bartlett pear (1770) and the Delicious apple (1870) are still reproduced asexually to obtain the same quality product. Vegetative propagation is a form of reproduction by the leaves, stems, or roots of the parent plant. Asexual reproduction can also be done artificially by cutting, grafting, and layering.

Sweet potatoes, dahlias, and asparagus are all reproduced through tuberous roots. The roots of such plants contain buds that can form leaf shoots under favorable conditions. Potato and ginger are reproduced through stem tubers, the small buds present on the vegetable. Bryophyllum reproduces through leaf margins. If a leaf falls on damp soil, it can give rise to a new plant. Runners like strawberry reproduce through stems. Plants such as cacti reproduce when a part becomes detached from the parent plant. The detached part then starts a life of its own. The new plants produced by vegetative propagation are an exact copy of their parent plants.

Sexual and asexual reproduction are different adaptations that plants have used to perpetuate their species even in adverse conditions. Plants with flowers use sexual reproduction by attracting various agents of pollination. Plants without flowers rely on stems, leaves, and roots that form buds and produce identical copies!

One of the great things about growing plants is finding out more about the other wildlife associated with plants with which we share the earth.

There are millions of them out there, from grazing animals to microbes – in the soil, on the plants, in the air, all busily supporting our world as we go about our day-to-day lives. By growing wild flowers you can help support them too.

How do insects help a plant to reproduce

Why do insects and animals matter?

  • Everything is connected in our complex and amazing natural world.
  • Insects such as bees and butterflies are important pollinators, helping plants to reproduce. In return, the plants provide them with food in the form of nectar and pollen.
  • Pollinated plants produce seeds, fruit and vegetables for us and other animals to enjoy.
  • Insects themselves are a tasty source of food for birds and animals.

How do insects help a plant to reproduce

By planting a wildflower patch you’ll be helping to provide food and shelter for a host of insects and animals. Why not keep a note of the insects and animals you spot in your wild flower patch, compare notes with your neighbours and tell us what you’ve seen?

Below is a list of some of the animals and insects you should expect to see.

Bees

Bees are our main pollinators of flowering plants, bees are very important for wild flowers and for growing food. Although the bumblebee and honey bee may be the best known, there are actually over 250 species of bee in Britain.

Butterflies

Butterflies, like bees, need our help to stop their declining numbers. They use their long proboscises to feed on nectar from flowers and particularly like purple and yellow flowers.

Moths

Moths feed on nectar from a wide range of flowers. Many are nocturnal but day-flying ones occur too. We have over 2,500 species of moth in Britain compared with fewer than 70 species of butterflies and there’s no reason why moths shouldn’t be as popular.

Some of them are just as striking and colourful. Not all moths are nocturnal so keep an eye out for the impressive hummingbird hawk-moth, or the pink and green elephant hawk-moth in your Grow Wild patch. Both are particularly fond of lady’s bedstraw.

Wasps

There are hundreds of types of wasps, not just the yellow and black ones that annoy us in late summer. Many are pollinators and keep a check on the insect population by eating bugs such as aphids.

Hoverflies

Adult hoverflies feed on pollen and nectar while larvae help with pest control by feeding on insects such as aphids.

Ladybirds

You’ll already be familiar with the brightly coloured adults but the ugly, grey larvae with orange spots are voracious feeders of aphids so if you see these on your wild flowers you can relax, the aphids are in trouble.

Caterpillars

Caterpillars from butterflies and moths can be quite fussy about where they lay their eggs to ensure the right kind of food is available for their larvae to feed on. Wild flowers can often provide just the right caterpillar food. Lady’s bedstraw, for example, is a food source for the huge elephant hawk-moth caterpillar.

Birds

As well as feeding on seed heads of wild flowers, birds will also enjoy feasting on insects attracted to the plants.

Bats

Bats feed on insects flying in the air, such as moths.

Other mammals

Small animals such as hedgehogs munch their way through vast numbers of bugs and will benefit from insects attracted to your wild flowers.

How does growing wild flowers help insects and animals?

The good thing about growing native wild flowers is that they’re fantastic for our native wildlife. Having evolved alongside each other, our wildlife and wild flowers are well suited. Wild flowers provide food in the form of nectar, pollen, seeds, fruits and foliage. Common knapweed, oxeye daisy and lady’s bedstraw are all rich sources of nectar for pollinating insects. Wild flowers also provide nesting sites, larval food, forage and shelter.

Apart from growing wildflowers, how else can I help insects?

Be a little messy. Insects love a bit of debris and dead plant material for hiding and hibernating in. In autumn, sweep fallen leaves into a pile in a corner of your garden or create a log pile. This’ll provide somewhere for insects to hide out over winter.

Leave some of the stems of your wild flowers standing over winter to provide food and shelter for insects such as ladybirds. If you’re lucky you might even see birds such as goldfinches feeding on the seed heads of the knapweed, meadowsweet and ribwort plantain in your patch. Read Defra’s five simple actions for pollinators.

How can I identify the insects and animals I see in my garden?

The Field Studies Council (FSC) produces really handy guides to British insects, animals and much more besides. The Buglife and Royal Entomological Society also provide useful information on all manner of bugs (see the website links below).

What do insects and animals tell us about our local environment?

Insects and animals are an important part of a biologically diverse and healthy ecosystem. Bats, for example, can be a really useful indicator of the health of an area. They’re particularly sensitive to environmental changes so their numbers can tell us a lot.

Did you know?

Scientists recently discovered that flowers communicate with bees via an electrical signal. It seems that, along with signs such as colour, pattern and fragrance, flowers also emit electrostatic fields to attract pollinators such as bumblebees. The bees are able to detect and distinguish between these electrical signals.

You would think that humans would want to steer clear of the corpse flower when it blooms. After all, the plant releases a stench of rotting dead animal when it opens.

Still, visitors flock to botanical gardens for the chance to catch a whiff. Considering that corpse flowers bloom for only 24 hours every two to 10 years, the opportunity to be there for a rare, if smelly, event is a hard one to pass up.

The odor the corpse flower releases is supposed to be alluring only to certain insects. It's part of an elaborate deception the flower engages in so that it can reproduce.

Smelly bloom

How do insects help a plant to reproduce

After growing up to 10 feet, the corpse flower unveils two different components that are key to its survival.

The first is the spathe, a burgundy-colored “skirt” that resembles a very large circular petal. In fact, it’s actually a modified leaf that, according to KQED Science, looks like raw steak up close. It also releases an aroma similar to jasmine, making for an odd combination of sight and smell.

The second part of this elaborate ruse is the spadix, a yellow rod-like structure that gives the corpse flower its scientific name: Amorphophallus titanum, or, roughly translated, "giant deformed phallus."

Both parts play a role in the corpse flower's reproduction. The spathe provides what looks like the red guts of a dead animal, while the spadix helps to warm the flower so as to better diffuse the stench. These effects attract would-be pollinators, insects that like to lay their eggs inside rotting animals.

From the base of the spathe, more than 30 chemicals are released over the course of blooming, shifting from sweet to "dead rat in the walls of your house," Vanessa Handley, director of collections and research at the University of California Botanical Garden in Berkeley, told KQED Science.

How do insects help a plant to reproduce

Neither part is where reproduction occurs. For that, you have to go deep inside the plant to find male and female flowers.

At the base of the bloom are male flowers that look like corn kernels and female flowers that look like small bulbous stalks. When the corpse flower opens, these female flowers are ready to receive pollen from another corpse flower. They become sticky so as to trap the pollen grains carried by insects thinking this is a good place to lay their eggs.

How do insects help a plant to reproduce

After this period, the male flowers begin to release stringy pollen that will, hopefully, be picked up by the insects and carried to another corpse flower.

"They fumble around and leave, and in the best-case scenario they're covered in pollen that they carry to another receptive plant," Handley said.

If some of the string pollen from the male flowers falls onto the female flowers, it's not a big deal. By that point in the process, the female flower is no longer sticky and isn't trapping pollen. It wants fresh genetic material, after all, not material from itself.

Conserving the corpse flower

Of course, when corpse flowers are in a botanical garden, their odds of reproducing are lower than they would be in the wild. Often, no other plants are open at the same time. So biologists may need to lend a helping hand.

Scientists can cut a hole in the side of the flowering base and scrape the stringy pollen from the male plants with a metal spatula. This pollen is frozen and is later used to pollinate another corpse flower somewhere else. Scientists don't do this too often, though. It's not good for the plant.

"This might cause the plant to put all its energy into its seeds," Ernesto Sandoval, of the UC Davis Botanical Conservatory, told KQED, "and the plant itself dying."

Such efforts are needed once in a while, though. The corpse flower, given its unique appearance and rare blooming scheduling, makes it a popular poaching target in its native Sumatra. Deforestation on the large Indonesia island also threatens the survival of the plant.

How do insects help a plant to reproduce

The presence of insects and pests is very common in a garden because it is a buggy place for insects. The presence of green vegetables, plants and plantations in a garden always attract plenty of insects. Some insects damage and harm the plantations but some other types of insects increase the growth of plants. Hence it is very important to control the population of insects in a garden to make sure the best performance of plants. There are hundreds of ways to control and kill the insects and pests like insecticides, pesticides and biological control. The use of cultural techniques and IPM is also best to lower the population of insects. The use of pesticides is associated with countless health hazards and drawbacks. The use of biological control is best to maintain the lower the population of insects. The most famous beneficial insects are following.

1) Green lacewing

It is one of the most famous beneficial bugs. It feeds on honeydew, nectar and pollen of plants. It is also called the aphid lion because it suppresses the insect population very fast. It is a soft bodied insect and it has many growth stages. The larval stage of this insect is very sensitive and soft. The adult green lacewing is two paired insect. It kills and eats the other harmful insects. It feeds on the honeydew of aphid. The aphid is a staple food of green lacewing. This beneficial insect can be used to control the population of different insects and pests.

2) Praying Mantids

It is a predator and it kills and eats other insects fast. It can catch other caterpillars very fast. It can consume hundreds of larvae in few minutes. Hence it can help to control the growth of insects in a better way. It is a very active predator. It can kill any other insect with ease. The larvae of this insect live in the soil. They create galleries in the soil; hence they increase the aeration of soil. This activity directly increases the growth of plants and vegetables. It is simple to control garden insects with the help of Praying Mantids.

3) Ground beetles

They are black colored and large size beetles. They have three to four growth stages. They help the vegetables to grow fast. The key role of ground beetle is that they feed on harmful insects like cutworms, maggots and flies. They also feed on aphids and jassids. The larvae of this insect live in the soil and they help to mix the fertilizer in the soil well. They also help to control the population of garden bugs.

4) Small pirate bugs

The presence of small or tiny pirate bugs can also lower down the population of insects in garden. They are very active feeder of aphid, jassids and thrips. The presence of pirate bugs in your garden can make sure best growth and development. Hence it is recommended beneficial insect for garden and house. There are also many other beneficial garden insects.

5) Syrphid flies

The use of syrphid is also best. These flies are similar to other flies due to presence of colored margins on the body. Similarly they have one pair of wings to fly or move. This insect is the feeder of aphids. They also help in the pollination of plants just like butterflies which are attracted by certain flowers in the garden . This fly moves from one flower to another flower. They also increase the growth of garden. The pollination is basic requirements of growth. It is one of the best beneficial insects.

      Pollinators by Numbers

      Three-fourths of the world’s flowering plants and about 35 percent of the world’s food crops depend on animal pollinators to reproduce. More than 3,500 species of native bees help increase crop yields. Some scientists estimate that one out of every three bites of food we eat exists because of animal pollinators like bees, butterflies and moths, birds and bats, and beetles and other insects.

      How Animal Pollination Works

      Pollinators visit flowers in their search for food (nectar and pollen). During a flower visit, a pollinator may accidentally brush against the flower’s reproductive parts, unknowingly depositing pollen from a different flower. The plant then uses the pollen to produce a fruit or seed. Many plants cannot reproduce without pollen carried to them by foraging pollinators.

      Pollinators Are in Trouble

      You may have heard that bees are disappearing and bats are dying. These and other animal pollinators face many challenges in the modern world. Habitat loss, disease, parasites, and environmental contaminants have all contributed to the decline of many species of pollinators.

      Why should I protect insects ?

      While many insects can seem like pests, they provide a wide range of services to other plants and animals in our environment. In fact, a diverse range of insect species is critical to the survival of most life on Earth, including bats , birds, freshwater fishes and even humans! Along with plants, insects are at the foundation of the food web, and most of the plants and animals we eat rely on insects for pollination or food. For example, 96% of songbirds feed insects to their young.

      If a dollar value was put on the services insects provide, this would equal roughly $70 billion in the U.S. alone. These services include:

      • Pollinating food crops and natural habitat: According to the U.S. Natural Resources Conservation Service, roughly 35% of the world’s food crops depend on pollinators to reproduce. That means you can thank a pollinator for about one of every three bites of food you eat. According to the U.S. Fish and Wildlife Service, more than 100,000 different animal species play roles in pollinating the 250,000 kinds of flowering plants on Earth, with insects like bees, wasps, moths, butterflies, flies and beetles being the most common. Additionally, some insects are natural predators to pests that may harm food crops.
      • Removing waste: Some insects are known as decomposers, meaning they break down dead materials like fallen leaves and animal carcasses and turn them into simpler materials, making nutrients available to primary producers like plants and algae. In other words, decomposers are nature’s own recycling system.
      • Controlling pests: Only a very small fraction of insects in the world are considered by humans to be pests, meaning they cause harm to people, plants, animals and buildings. While insect pest control costs the U.S. economy billions of dollars annually, this number would be much higher if it weren’t for the countless beneficial insects that serve as natural predators to pest species, like fire ants and mosquitoes. Additionally, some parasitic insects like small wasps lay their eggs inside pest species, driving their population down. To adequately control pests, we need beneficial insects.
      • Providing nutrition for wildlife: Insects are the primary menu item for many reptiles, birds and amphibians. If insect populations continue to decline, some food webs might collapse entirely.

      We also depend on insects for silk, dyes, honey and medical and genetic research. But, aside from the services insects provide, they are simply fascinating animals that spark curiosity in humans, especially children. These incredible creatures exhibit many extraordinary behaviors that are unthinkable in other forms of life and have inspired technology that we use today, like drones! Take some time to really observe the insects in your backyard, what behaviors do you see that captivate you?

      Since many insects have yet to even be discovered, there may be benefits we don’t even know about yet!

      How do insects help a plant to reproduce

      The peanut, like all angiosperms, possess an alternation of generation life cycle. An alternation of generations means the plant, in this case the peanut, switches between the haploid (n) and diploid (2n) stages during its life. A haploid cell has half the normal number of chromosomes for a particular organism and needs to fuse with another haploid cell in order to continue on with its life cycle. Simply put, the haploid cell is the reproductive cell. The diploid cell, on the other hand, has a full set of chromosomes. In the peanut, the diploid sporophyte phase is the more dominant of the two phases. The haploid gametophyte is small and nutritionally dependent on the sporophyte.

      Peanuts are self-pollinating plants, meaning they do not require outside aid, such as bees or other insects carrying pollen from one plant to another, in reproduction. After the seed is planted, the first flowers begin to appear in four to six weeks and continue blooming for six or more weeks. As each flower grows older, it drops closer and closer to the ground so that, when it does come time to pollinate, the ovary is close to the ground to allow for easy insertion of the subterranean pod. When it is time to start pollinating, one and only one flower opens at sunrise and releases its pollen. There can be anywhere between one and several days between each flower blooming. Fertilization of the seed takes place between eight and nine hours after the pollen is released. Eight to 14 days after fertilization occurs, the ovary elongates into a peg, is driven vertically into the ground, and turns horizontal. Underground, the horizontal peg matures into a pod and, after seven to nine weeks, becomes the peanut we all recognize. It is for this underground ripening that the peanut was given its scientific name, as explained under classification.
