Avermectin has stomach poisoning and contact killing effects on mites and insects, and cannot kill eggs. The mechanism of action is different from that of general pesticides in that it interferes with neurophysiological activities and stimulates the release of γ-aminobutyric acid, while aminobutyric acid can inhibit nerve conduction in arthropods. Adult mites, nymphs, and insect larvae appear paralyzed upon contact with avermectin, are inactive, do not eat, and die after 2 to 4 days. Because it does not cause insects to quickly dehydrate, avermectin has a slower lethal effect. Avermectin has a direct contact killing effect on predatory insects and parasitic natural enemies, but it has little damage to beneficial insects because there are few residues on the plant surface. Avermectin is adsorbed in the soil and does not move, and is decomposed by microorganisms, so it has no cumulative effect in the environment and can be used as an integral part of comprehensive control. It is easy to prepare, and it can be used by pouring the preparation into human water with a little stirring, and it is also safer for the crops. It will not cause any harm when used according to the method introduced. Suitable for crop vegetables, citrus, cotton, etc. Avermectin pesticides play an important role in the pest control system. Avermectin is a new type of antibiotics, which has the characteristics of novel structure and dual use for agriculture and livestock. With the improvement of people’s living standards and the call for green food, biological pesticides have become more popular in the current pesticide market. Authorities predict that the 21st century will be the century of biological pesticides. It is reported that the sales of European biological pesticides will increase from US $ 100 million in 1997 to US $ 169 million in 2004. Avermectin is the most popular and highly competitive new product in the current biological pesticide market.
