What's the effect of avermectin?

What's the effect of avermectin? Which pests does avermectin have effect on? Please introduce that avermectin has stomach toxicity and contact killing effect on mites and insects, but can not kill eggs. The mechanism of action is different from that of general insecticides in that it interferes with neurophysiological activities and stimulates the release of γ-aminobutyric acid, which inhibits nerve conduction in arthropods. The adults, nymphs and insect larvae of mites showed paralysis symptoms after contact with avermectin, did not move, did not feed, and died 2-4 days later. Avermectin has a slow lethal effect because it does not cause rapid dehydration of insects. Avermectin has direct contact effect on predatory insects and parasitic natural enemies, but it has little damage to beneficial insects because of less residue on plant surface. Avermectin adsorbed by the soil does not move and is decomposed by microorganisms, so it has no cumulative effect in the environment and can be used as a part of integrated control. The preparation is easy to prepare and can be used by pouring the preparation into the water and stirring slightly. It is also safer for crops. The first characteristic of avermectin is that avermectin is efficient and can kill a variety of pests, including Lepidoptera, Diptera, Homoptera, Coleoptera, leaf mites, rust mites, and highly effective agents to kill a variety of parasitic nematodes. the second characteristic is that it is different from other insecticides and is not easy to produce drug resistance. The third feature is safety, because the chemicals sprayed on the plant surface can be decomposed quickly, so it is safer to natural enemies, less pollution to the environment, even if overused 10 times will not cause plant drug damage. Disadvantages: first, the speed of killing pests is slow, pests eat avermectin, first slow to move, do not eat, and then die 2-4 days later, farmers often think that the efficacy is not good; second, the original drug is toxic, all kinds of proprietary medicines are low active ingredient content to reduce the toxicity level of the drug, but still need to pay attention to safety in use.
