What are the top ten beneficial insects? A roundup of common beneficial insects

China has a very rich variety of insects. If we really go into detail, they can be divided into many orders. Today let's mainly talk about which insects are beneficial, especially the common insect species that are beneficial to farmers.

1. Dragonfly

Dragonflies are an important group of natural enemy insects beneficial to humans, specializing in preying on many agricultural, forestry and animal husbandry pests such as flies, mosquitoes, leafhoppers, horseflies and midges, and small butterflies and moths. Dragonfly larvae (nymphs) live in water, and their lifespan varies by species. They can be used to monitor environmental pollution and have medicinal, edible and ornamental value.

2. Bee

There are many kinds of bees. They can pollinate crops, fruit trees, vegetables, forage grass, oil tea crops and medicinal plants, increasing yields.

3. Mantis

A carnivorous insect. Any small insect can be preyed on by the mantis, especially flies, mosquitoes, locusts, and the eggs, larvae, exposed pupae and adults of moths and butterflies, which are all suitable prey for it. Even large insects such as cicadas and migratory locusts are also among their prey.

4. Seven-spot ladybird

The seven-spot ladybird mainly feeds on aphids, and sometimes also eats small soil particles, fungal spores and some small insects, and in autumn it often feeds on plant pollen. It is widely distributed in Africa, Europe and Asia.

5. Earthworm

Earthworms dig burrows and loosen the soil and decompose organic matter, creating good conditions for the growth and reproduction of soil microorganisms. They play a special role in soil improvement, eliminating public hazards, protecting the ecological environment, material cycling and biodiversity. At present, many countries use earthworms to treat household waste and organic waste and to purify sewage.

6. Dung beetle

Dung beetles usually feed on dung or humus and play an important role in the balance of the ecosystem. The ecological value of dung beetles includes transporting dung underground, the secondary dispersal of seeds, pollination, and the control of harmful organisms.

7. Trichogramma wasp

It mainly parasitizes aphids, scale insects and whiteflies, and has a considerable control effect. Adults feed on the honeydew secreted by aphids and scale insects as well as the body fluid flowing from the puncture wounds made on the host body when laying eggs.

8. Predatory mite

Although it is small in size, it is actually a major natural enemy of red spider mites. It can eat agricultural pests completely clean, not even sparing their eggs.

9. Green lacewing

A predatory insect, distributed across northern and southern China. Because green lacewings can effectively prey on a large number of important agricultural pests, people have widely carried out work to use green lacewings artificially to eliminate pests.

10. Silkworm

The silkworm is a holometabolous insect. The most common is the mulberry silkworm, also known as the domestic silkworm, one of the economic insects that feed on mulberry leaves and spin silk to form cocoons.
