The Introductction of Avermectin
Avermectin is a class of 16 membered macrolide compounds with insecticidal, acaricidal and nematicidal activities, which was first developed by Nishimura, Nishimura, and Merck of the United States. It is produced by fermentation of Streptomyces avermitilis. The natural abamectin contains 8 components, mainly including 4 components, namely A1a, A2a, B1a and B2a, with the total content ≥ 80%; The corresponding four homologues with smaller proportion are A1b, A2b, B1b and B2b,
The Application & Function of Avermectin
Avermectin has stomach toxicity and contact killing effect on mites and insects, and cannot kill eggs. The mechanism of action is different from that of common pesticides, which is to interfere with neurophysiological activities and stimulate release γ- Aminobutyric acid, and aminobutyric acid can inhibit the nerve conduction of arthropods. Adults, nymphs and larvae of mites will appear paralysis symptoms after contacting with abamectin, and will not move or feed, and will die after 2-4 days.
Avermectin has a slow lethal effect because it does not cause rapid dehydration of insects. Although abamectin has a direct contact killing effect on predatory insects and parasitic natural enemies, it has little damage to beneficial insects due to less residue on the plant surface. Avermectin will not move when adsorbed by the soil in the soil, and will be decomposed by microorganisms, so it has no cumulative effect in the environment and can be used as a component of comprehensive control. It is easy to prepare, and the preparation can be used after being poured into water and stirred slightly, which is also safe for crops
