Introduction: Avermectin is a kind of 16-membered macrolide compound with insecticidal, acaricidal and nematicidal activities, which is produced by fermentation of Streptomyces avermectin. The natural avermectin contains 8 components, mainly including 4 kinds, namely A1a, A2a, B1a and B2a, with a total content of ≥ 80%; The corresponding four homologues with smaller proportion are A1b, A2b, B1b and B2b, with total content ≤ 20%. Avermectin pesticides on the market are mainly composed of abamectin (avermectin B1a+B1b, in which B1a is not less than 90% and B1b is not more than 5%), and are calibrated by the content of B1a. Avermectin has gastric toxicity and contact killing effects on mites and insects, and cannot kill eggs.
