Abamectin (also called avermectin B₁) is a widely used insecticide and anthelmintic. Abamectin, is a member of the avermectin family and is a natural fermentation product of soil dwelling^[1] actinomycete Streptomyces avermitilis.^[2] Abamectin differs from ivermectin, the popular member of the avermectin family, by a double bond between carbons 22 and 25.^[2] Fermentation of Streptomyces avermitilis yields eight closely related avermectin homologs, with the B_1a and B_1b forms comprising the majority of the fermentation.^[3] The non-proprietary name, abamectin, refers to a mixture of B_1a (~80%) and B_1b (~20%).^[3] Out of all the avermectins, abamectin is the only one that is used both in agriculture and pharmaceuticals.^[4]
