avermectins

a group of chemically related anthelmintics belonging to the macracytic lactones, and produced by fermenting Streptomyces avermitilis. A number of compounds with anthelmintic activity are produced by this process. The combination of two dehydrogenated avermectins is called ivermectin.

The avermectins are streptomycete-derived macrocyclic lactones that have high potencies against insect pests in several orders, phytophagous mites, and the plantparasitic nematode Meloidogyne incognita (Tylenchida: Meloidogynidae) (Ishaaya & Horowitz 1998).
Avermectins mainly the abamectin are the secondary metabolites derived as fermentation product of Streptomyces avermitilis and have been used extensively to control both the endo- and ectoparasites (Diao et al.
Other avermectins can also cause toxicity, including doramectin (Dectomax), eprinomectin (Eprinex), and abamectin.
This class of products, known as avermectins, were revolutionary and provided improved control of a large number of parasites at much lower doses of active material along with a significantly improved safety profile to humans, animals and the environment.
Avermectins do not appear to have a persistent activity against nematodirus battus, which they do against some other worms.
