Is there a scientific classification of beneficial pests and pests?

Scientific. The difference between the two is whether it is harmful to human production and life, the beneficial ones are called beneficial insects, and the harmful ones are pests. But some beneficial insects can also have small harms.

It's not scientific, humans just call what is beneficial to humans beneficial insects, and what is harmful to humans is called pests. However, some insects are beneficial to the environment, so the division is not scientific.

The concept of beneficial insects and pests is artificially formulated, in fact, there is no such concept in nature, and the existence of every living thing is a link in the ecological chain. As human beings, this division is scientific.

Pests include flies, mosquitoes, cockroaches, lice, aphids, locusts, diamondback moths, corn borers, termites, rice elephants, longhorn beetles, snails, rat women, etc. Beneficial insects include bees, silkworms, ladybugs, praying mantises, aphid-eating flies, parasitic wasps, lacewings, etc.

Pests are a general term for insects that are harmful to humans. In our own right, it is a general term for insects that adversely affect our human survival. Whether an insect is beneficial or harmful is quite complex and often varies depending on the time, place, and quantity.

We tend to dismiss any insect that competes with us as a pest, when in fact they are only harmful to humans when they are in a certain number.

The role of beneficial insects.

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.

In nature, the cockroach is a beneficial insect, non-toxic, (non-toxic does not equal sterile) basically non-aggressive. Occasional attacks are also acts of self-preservation.

Earwig furficulidae is a general term for the family Earwig Wingaceae. Body length 4 mm 35 mm, body narrow, slightly flattened, head flattened and broad, antennae filamentous, no monocular, mouthparts chewing; The dorsal plate of the prothorax is well developed, the square body surface is leathery, shiny; Forewings specialized to very small leathery wings; hindwings large, membranous, fan-shaped or slightly rounded, often exposed outside the forewings; tail whiskers; no ovipositor; The glandular folds of the 3rd and 4th segments of the abdomen can secrete special odors to drive away enemies; There is a pair of pincer-like tails at the end of the tail for defense. In the cold zone, it overwinters with adults, and its eggs are laid in bunches in the caves on the surface of the soil, and the sexes live together, and they have protective offspring, nocturnal habits, and are omnivorous; The predators of fruit tree pests, a few species are harmful to flowers, stored grains, stored fruits, silkworms and fresh insect specimens, and some are ectoparasites of bats and rats.

A total of 211 species have been recorded in China [1-2].

The Chinese name is 蠼螋.

Aliases. Splints, nail clippers, splints, or scissor insects, ear clips.

This is a bad bug, we call it Ligutu.

3. The functions of beneficial insects are as follows: assisting crop growth, controlling pests, improving environmental sanitation, etc.

2. Pests

1. Pests refer to insects and animals that have adverse effects on human life and production activities, and are divided into insects and non-insects.

Common pests mainly include bag moth, spiny moth, large silkworm moth, foot moth, stem moth, dead leaf moth, cricket, longhorn beetle, small silverfish, aphid bench silver qi, psyllid, thrips, leafhopper, etc.
