Information on the description of beneficial insects 15

Common beneficial insects are earthworms, bees, dragonflies, etc.

1) Earthworms swallow a large amount of soil every day, absorb the rotten leaves and small organisms in the soil, and then excrete the soil. This makes the soil loose and fertile, which is very conducive to the growth of crops and their own growth.

Earthworm Benefits for Humans: The benefits of earthworms for humans are numerous.

Second, earthworms can improve the fertility of the soil, and the decaying organic matter and a large number of soil particles eaten by earthworms are excreted from the body through digestion to form feces, which are rich in nitrogen, phosphorus, potassium and other nutrients.

Thirdly, the body of earthworms contains a lot of protein and fat, and the nutritional value is very high, making it an excellent protein feed and food.

Fourth, the use of earthworms to treat organic waste is very efficient, for example, 100 million earthworms can swallow 40 tons of organic waste in a day.

Therefore, earthworms have many benefits to human beings, so China and many countries in the world are striving to carry out the use and breeding of earthworms. Dragonflies are beneficial insects, they are almost born to catch pests, which is of great help to human life, not only good for human health, but also plays a great role in the yield of crops.

2) The amount of food eaten by dragonflies is also very amazing.

It is a carnivorous insect that feeds on mosquitoes, flies and other small insects. A large green dragonfly, commonly known as the "green flute", can eat about 2,000 aphids and other small flying insects a day. It eats mosquitoes, flies, and the like, of course, and welcomes all small moths and insects that can fly and crawl.

Such a large number of pests for human beings to be eliminated is well deserved, and it is well deserved to be called "beneficial insects".

(3) Bees are one of the insect groups that are beneficial to humans. Usually broadly refers to production bee species: Western honey bee and Chinese honey bee.

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. Honey is a commonly used tonic and is known as "the milk of the elderly"; Bee pollen is known as the "miniature nutrient bank", and royal jelly is a high-grade nutrient, which can not only enhance physical fitness and prolong life, but also lead to chronic diseases such as neurasthenia, anemia, and gastric ulcers; Bee venom is effective for rheumatism, neuritis, etc.; Both beeswax and propolis are raw materials for light industry.

Beneficial insects refer to insects that are beneficial to other organisms, mainly including: bees, praying mantises, silkworms, dragonflies, lacewings, aphid-eating flies, parasitic wasps, etc.

1. Bees. 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.

2. Praying mantis. The common name of insects of the class Praying Mantis, which usually feeds on catching other species of insects, mantis takes butterflies, cicadas, and locusts as their main food, and they destroy most of the harmful insects.

3. Silkworms. It is one of the longest-lasting and largest insects that have contributed to humans. Silkworms are lepidopteran insects, the main raw material of silk, and occupy an important position in human economic life and cultural history.

Legend has it that as early as more than 3,000 years ago, the wife of the Yellow Emperor began to "raise silkworms and extract silk". Silkworms go through four completely different stages of development in morphology and physiology, including eggs, larvae, pupae and adults, and the different parts of each stage and their metabolites have a wide range of medicinal value.

4. Dragonflies. It has two pairs of transparent wings, a pair of large eyes, and is reticulated. Adults generally fly in ponds or rivers to prey on flying insects, in addition to a large number of mosquitoes, flies and other harmful insects, some can also prey on butterflies, moths, bees, in fact, beneficial insects.

There are more than 5,000 known species of dragonflies.

5. Lacewings. It is a predatory insect and belongs to the order Veloptera. There are 86 genera with a total of 1,350 species in the world, and according to the survey, there are about 100 species in 15 genera recorded in China, distributed in all parts of northern and southern China.

Because lacewings can effectively prey on a variety of important agricultural pests in large quantities, the artificial use of lacewings to eliminate pests has been widely carried out.

<> common beneficial insects are dragonflies, praying mantises, spiders, seven-star ladybugs, frogs, aphid-eating flies, insectivorous flies, earthworms, snakeworms, etc. Dragonflies are carnivorous insects and eat pests. The larvae of dragonflies live in water and can prey on small animals or other small animals, and adults can prey on mosquitoes and flies in large quantities, and some can also prey on pests such as butterflies, moths, and bees.

Mantis.

The praying mantis, also known as the knife mantis, is an invertebrate, a carnivorous insect, and a beneficial insect. Praying mantis is a carnivorous insect, its food has cotton aphid, red bollworm, corn borer, vegetable borer, cabbage worm, beetle, flies, grasshoppers and other more than 60 kinds of pests of adults and larvae, mantis is also the locust's sworn enemy.

Spiders

Spiders are classified as "beneficial insects" because they eat cockroaches, flies, etc. Spiders are the natural enemies of many agricultural and forestry pests, and play an important role in the control of envy organisms, and the protection and utilization of spiders has become an important part of biological control. Spiders feed on insects, other spiders, myriapods, and some spider orange bushes also feed on small animals.

Earthworms

Earthworms can be used as fodder, food and medicinal materials in the soil, and the soil is loosened, and the air and water can go deeper into the soil to facilitate plant growth, which can play a role in improving the soil and improving the fertility of the soil.

Worms

Grasshoppers live in dark and damp places inside and outside houses, and like to prey on spiders, bed bugs, termites, cockroaches, silverfish, ants and other household arthropods, and use their fangs to inject venom into their bodies to kill pests, so they are beneficial insects.

1. There are many kinds of beneficial insects, such as bees, dragonflies, praying mantises, frogs, seven-star ladybugs, parasitic wasps, aphid-eating flies, lacewings, earthworms, tiger beetles, foot beetles, ash insects, lac insects, horned aphids, silkworms, tussah silkworms, grate silkworms, maple camphor silkworms, etc.

2. Beneficial insects refer to insects that are beneficial to human production and life, such as agriculture and medicine. Beneficial insects protect the natural ecological balance and thus better protect the environment. Biological control is a method of using the natural enemies of pests to suppress pests, because pests themselves are the food of many insects and other animals, and they are also the hosts of many microorganisms.

The reason why some pests are not able to survive in large numbers in old production areas is sometimes not due to unsuitable weather, lack or lack of food, or lack of reproduction, etc., but because they are predated or parasitized by natural enemies, resulting in a large decrease in population. The natural enemies of pests, i.e., beneficial insects, can be easily divided into two categories: predatory or parasitic.
