Inspiration for the use of insects to treat insects, other examples of insects to treat insects

It's not very easy to use, it's just okay to maintain the ecology, it has no real meaning in agricultural production, and it works well when planted in protected areas! It is mainly the use of natural enemies to control agricultural pests1

1. During the Yuanfeng period of Song Shenzong, Zifang insects were born in the Gyeongju area, which were harming the crops in the autumn fields. Suddenly, an insect appeared, looking like it was out of the dirt"Dog scorpion"and they have pincers on their mouths, and they are found all over the place; As soon as it encounters the subsquare worm, it fights the subsquare with pincers and splits the subsquare in half. Ten days later, all the sub-square insects were eliminated, and a bumper harvest was achieved at the end of the year.

2. The red-eyed bee reproduces and produces viruses in the ovaries of pests such as woodworms, so that virus epidemics are formed in the pest population, so as to achieve the biological control effect of insect control.

3. Xiao Cai'e's natural enemy bee is very small and small, and it is difficult to see it without a magnifying glass. When it lays its eggs, it lays its eggs in the larvae of diamondback moths. When the eggs hatch into larvae, the larvae eat the diamondback moth larvae, which is even more effective if a commonly used natural insecticide that does not pollute the environment is used in conjunction with this method of insect control.

Insect control The use of natural enemy insects to control pests is called insect control, which includes the use of beneficial mites. The use of natural enemy insects is the most widely used and most widely used method of biological control. According to the way natural enemies feed insects, they can be divided into two categories, namely predatory natural enemies and parasitic natural enemies.

1. Predatory natural enemies: There are many types of predatory natural enemies, among which the effect is better. Ladybugs, lacewings, aphid-eating flies, insectivorous flies, insectivorous bugs, wasps, walking insects and predatory mites, etc., such natural enemies generally eat a large amount of insects, and in the process of their growth and development, they must eat several, dozens or even hundreds of insects to complete their development.

Therefore, the rampant effect of controlling pests in nature is very obvious. For example, the application of ladybugs, lacewings, wasps and other aphids and cotton bollworms in cotton fields has achieved certain results.

2. Parasitic natural enemies: This kind of natural enemies parasitize the body of pests, feed on their body fluids and internal organs, and kill pests, mainly including parasitic wasps and parasitic flies.

Parasitic wasps: It is a bee that mainly parasitizes the body of other insects, and the control of agricultural pests is very extensive and has achieved certain results. For example, the use of red-eyed bees and cocoon bees to control pine caterpillars, corn borers, rice bracts, rice leaf rollers, pod borers, bean armyworms, soybean heartworms, bean moths, cotton bollworms, apple leaf rollers and other agricultural pests.

All parasitic eggs, larvae and pupae cannot complete their development and die halfway.

Parasitic flies: mostly parasitize in the larvae or pupae of butterfly moths, feed on their internal nutrients, and cause their death. Parasitic flies often lay eggs on the larvae or pupae of other pests, and after hatching, the larvae burrow into the body to feed on body fluids.

Some eggs are laid on plant leaves and are fed by pests into the digestive tract for parasitism.
