What insects are beneficial and what do they eat?????

There are many kinds of insects that are beneficial insects, such as the seven-star ladybug, they feed on the pests of crops, their life is very short, mainly feed on agricultural pests, and they fly slowly, slow motion and gentle.

Generally speaking, insects such as praying mantis and dragonflies belong to one kind, and dragonflies often use mosquitoes as their food.

The so-called beneficial insects and pests are divided from the perspective of humans. Eating pests and benefiting human survival are beneficial insects. For example, the seven-star ladybug, which eats aphids that are harmful to agriculture, is a beneficial insect.

Insects, including resource insects such as bees, silkworms, etc.

In the narrow sense, the concept mainly refers to natural enemy insects, which are the opposite of pests, and can prey on or parasitize on pests.

Beneficial insects, of course, feed on pests.

Dragonflies eat rice flying insects, seven-star ladybugs eat bud worms, and red-eyed bees eat bud eggs.

Beneficial insects are insects that are beneficial to humans in some way, such as praying mantises, frogs, snakes, lizards, etc.

Praying mantis eats aphids, corn borers, mealworms, painted powder geese, flies. Ladybugs eat aphids, spiders spread their webs to catch pests, frogs and other frogs, eat mosquitoes, crickets, flies, moth beetles, etc.

Some insects eat smaller insects, or they eat plants, or seeds. Some are by eating fruits. Eat meat and eat something more corrosive.

Insects have the same species, and the way they feed is also different. It can be used as food, whether it is plants, wood, spoilage, etc.

1. As far as the object of food is concerned, insects are herbivorous (eat plants), such as beetles mainly feed on the roots or seedlings of crops.

2. Carnivorous (eating live animals), praying mantis has the behavior of female insects eating male insects when there is a serious lack of food.

3. Satrivorous (feeding on animal and plant carcasses and feces), dung beetles are a class of scavenging insects, they eat dead carrion.

4. There is also a class of insects that can eat both plants and animals, we call them omnivorous insects, the notorious "Xiaoqiang" (cockroaches) is the most famous omnivorous insects, their food is very wide, especially like to eat fat, so some places call them "oil stealers".

bees, dragonflies, praying mantises, spiders, ladybugs, frogs, wild flies, insectivorous snakes, near worms; meandering, etc.

The broad concept of beneficial insects refers to all insects that are beneficial to humans, including resource insects. For example, silkworms, in the narrow sense, refer to natural enemy insects that can prey on pests or parasitize the body of pests, which is the opposite of pests. We usually understand insects that are beneficial to human production and life as beneficial insects, such as bees, dragonflies, praying mantises, etc.

When it comes to beneficial insects, the first thing that comes to mind is the industrious little bees. Bees are really good insects for plants, they collect honey during the day and make honey at night, so we can drink such sweet honey. At the same time as collecting honey, bees will also pollinate plants, help plants reproduce and bear fruit, not only never harm the plant, but also prolong the life of the brewed honey, **neurasthenia and anemia.

Dragonfly is a good-looking insect, if you don't know what beneficial insects are, Jing Fly is the most obvious beneficial insect It can prey on seeds in the water, that is, it prey on mosquito larvae. The adults of dragonflies are not only not ugly, they always fly in ponds and rivers, and then prey on those flying insects, mosquitoes, flies and other pests.

Beneficial insects are: bees, seven-star ladybugs, praying mantises, silkworms, and earthworms.

1. Honey bees: Hymenoptera, Honeybee family.

Bees live in groups, and there are three types of bee colonies: queen bees, worker bees, and drones.

Bees are one of the beneficial insect groups for humans, because bees work non-stop to obtain food, collecting honey during the day and making honey at night, and at the same time completing pollination tasks for fruit trees, which are important vectors for pollinating crops.

It pollinates crops, fruit trees, vegetables, pastures, camellia crops and traditional Chinese medicine plants, and the yield can be increased by several times to 20 times.

2. Seven-star ladybug: It is a predatory natural enemy insect of the Coleoptera ladybug family, and the adult can prey on wheat aphid, cotton aphid, locust aphid, peach aphid, scale insects, ticks and other pests, which can greatly reduce the damage of trees, melons and fruits and various crops to pests.

3. Praying mantis: the common name of insects of the class Mantis order, usually feed on catching other kinds of insects, praying mantis to butterflies, cicadas, locusts as the main food, they eliminate most of the harmful insects.

4. Silkworm: It is one of the insects that has contributed the longest and greatest to mankind.

According to legend, more than 3,000 years ago, the wife of the Yellow Emperor, the ancestor, began to "raise silkworms and extract silk".

5. Earthworms: like to live in moist soil, day and night, but earthworms are beneficial insects, it swallows a large amount of soil every day, absorbs the rotten leaves and very small organisms in the soil, and then excretes the soil, making the soil loose and fertile, which is very conducive to the growth of crops.

Therefore, the farmer and uncle are willing to have more earthworms in the land.

Extended information: Pests are: needleworm, ground tiger, grub.

1. Needleworm is the larvae of the knocking worm, and the common ones are Needleworm groove, Needleworm striocorum and Needleworm brown.

It mainly feeds on the underground roots and stems of crops, and feeds on seeds, germs or seedlings such as wheat, corn, and sorghum, causing root rot, bad roots, lack of seedlings, and broken seedlings.

Needleworms can also burrow into roots and stems to feed, and can also cause damage to tree seedlings.

2. The ground tiger is the most harmful underground pest, with larvae as the pest, and the adult metamorphoses into moths.

It is a typical diurnal and nocturnal underground pest, which feeds on the base of corn stalks, soybean sprouts, and various vegetables.

Resulting in a lack of seedlings, and even destruction of seeds in serious cases.

Ground tiger adults can be trapped, and they can be killed with a lure lamp, or they can be killed with sweet and sour venom.

3. Basically eat everything, which is very harmful to garlic roots, peanut pods, vegetable seedlings, just sown seeds, etc., and it is easy to induce other diseases in the place where the grub has eaten the moth, which seriously affects the yield.

These are listed below:

1. Scarab.

Scarab beetles live in grasslands, mountains, deserts, and jungles, and wherever there is animal droppings, they are industrious. Every day, they remove millions of tons of manure. Without this natural garbage remover, our planet would be untidy.

2. Mud wasps. Among the mud wasps, the genus with the largest species is the genus Arthrophit, with more than 1,000 species (including subspecies). Adult mud wasps are small to large with solid walls and a body length of 5 to 50 mm. The body is varied in size and color, and the body is often marked with red or yellow markings.

The body of the arthropod mud wasp resembles a wasp, the small-lipped mud bee moves quickly and neuroticly, the horn-breasted mud bee is stout and arrogant, and the cockroach mud bee specializes in catching cockroaches. The mud wasp is widely distributed in China, with a belly as thin as a grass stalk; The leaf teeth are golden green clay bee blue and metallic, and are mostly collected by insect lovers.

3. Red ants.

Red ants are very good at fighting, but they are very lazy, they are not willing to look for food, they are not willing to raise children, even if the food is next to them, they will not eat, and their food, clothing, shelter and transportation have to be done for them by servants. In order to achieve their goal, they go to rob their neighbors of different species of ants, such as black ants, snatch other people's pupae and transport them back to their nests. Soon after, the snatched chrysalis molted and became an active servant in the house.

4. Swallows. Swallows are the most willing to approach humans, and humans love this beneficial bird the most. It generally breeds from the island in April to July when it returns to farms close to farmland (insects). House swallows nest under the eaves of a farmhouse.

The nest is mostly made of mud and grass stems bonded with saliva, and the inside is covered with fine weeds, feathers, rags, etc., and some Artemisia annua leaves. The nest is dish-shaped.

5. Longhorn. The longhorn beetle generally overwinters in the trunk of a tree as a larvae or adult. After the adult worm emerges, some need to supplement nutrition, eating pollen, young branches, young leaves, bark, sap or fruits, fungi, etc., and some do not need to supplement nutrition. The lifespan of adults is generally more than 10 days to 1 2 months; But adults overwinter in the pupal chamber for up to 7 to 8 months, and males have a shorter lifespan than females.

The activity time of adults is related to the thickness and thinness of the small eye surface of the compound eye, which is generally thick, mostly active at night, and has phototaxis.

10 species of insects that are beneficial to humans: bees, silkworms, ladybugs, praying mantises, earthworms, dung shells, aphid-eating flies, parasitic wasps, lacewings, dragonflies.

Bees are very industrious animals. They collect nectar to make delicious honey. Bees are highly nutritious and can be made into a variety of cakes, nutrients, and cosmetics; They also complete plant pollination, which has enabled many crops to increase yields.

Therefore, bees are of great help to humans. Nowadays, modern people not only keep bees, but also raise bees, study bees, and professional beekeepers even use bees to create wealth. Bees are insects that are absolutely beneficial to humans.

Silkworms are undoubtedly a beneficial insect. Silkworms, also known as silkworms and silkworms, are one of the economic insects that spin silk and cocoons on mulberry leaves.

The main objects of mulberry silkworm cultivation are cocoons and silk. Silkworms go through four distinct stages of development in terms of morphology and physiological function: egg, larva, pupae and adult.

Different parts and metabolites at different stages of development have a wide range of medicinal properties.

Swallows, woodpeckers, frogs, seven-star ladybugs, red-eyed bees, dragonflies, bats, praying mantis can all eat pests. There are also some beneficial microorganisms that can kill pests. Such as avermectin, thuringibacillus, etc.

1. Swallows: They feed on insects, and they have always been accustomed to preying on flying insects in the air, and are not good at searching for insect food in tree crevices and crevices, nor can they omnivorous berries, seeds and leaves in winter like oak grouse and ptarmigans (some coniferous species do not lose their leaves even in winter).

2. Frog: love to eat small insects, good at finding small insects that move, its action when catching insects: a frog lying in a small dirt pit, hind legs curled up on the ground, front legs support, mouth open and face up, belly bulging waiting for something.

3. Seven-star ladybug:

4. Red-eyed bees:

It is an egg parasitic wasp, which can parasitize the eggs of lepidopteran pests such as corn borer, armyworm, stripe borer, cotton bollworm, Spodoptera litura, and ground tiger in corn fields. Red-eyed bees are a very useful type of insects.

5. Dragonfly: Hunting flying insects in flight. Mosquitoes and other insects that are harmful to humans, but they have a wide range of eating habits, so they cannot be relied on to control a certain insect pest. No more than 5,000 species are known.
