The avermectins are insecticidal or anthelmintic compounds derived from the soil bacterium Streptomyces avermitilis. Abamectin is a natural fermentation product of this bacterium. Abamectin is used to control insect and mite pests of a range of agronomic, fruit, vegetable and ornamental crops, and it is used by homeowners for control of fire ants. Doses of 50 to 200 ug/kg of ivermectin, a similar member of the avermectin family of comounds, is widely used to treat humans in the World Health Organization onchocerciasis (river blindness) program.
