Abstract

The avermectins are a new class of macrocyclic lactones derived from mycelia of the soil actinomycete, Streptomyces avermitilis (soil inhabiting which is ubiquitous in nature). These compounds were reported to be possessing insecticidal, acaricidal and nematicidal properties (Putter JG, Mac Connell FA, Preiser FA, Haidri AA, Rishich SS, Dybas RA. Experientia 37:963–964, 1981). They are commonly distributed in most of the cultivated soils and are in widespread use, especially as agents affecting plant-parasitic nematodes, mites and insect pests. The water solubility of avermectin B1 is approximately 6–8 ppb, and its leaching potential through many types of soil is extremely low. These physical properties also confer many advantages upon the use of avermectins as pesticides. Their rapid degradation in soil and poor leaching potential suggest that field applications would not result in persistent residues or contamination of ground water.

Avermectins offer an outstanding alternative to any of the available synthetic pesticides. Their novel mode of action, high potency and specific physico-chemical properties makes the avermectins excellent candidates for further insecticidal, acaricidal and nematicidal studies.
