Microorganisms and Synthetic Pyretnroid Insecticides

Pyrethroids are among the most potent insecticides known. The metabolism of both natural and synthetic pyrethroids is complicated and overpowering subject. Till date, there is not even a single well documented report on the uptake and metabolism of pyrethroid insecticides by microorganisms although extensive information is available on this aspect in relation to other types of insecticides. The structure stability of pyrethroids has led to the formation of products much similar to the most persistent and hazardous organochlorine insecticides. Thus signalling the impact of danger the usuage of these insecticides might have on our environment. The purpose of this review is to summerize our present knowledge on the uptake, metabolism and effects of synthetic pyrethroid insecticides towards microorganisms. Attempts is being made to address the deficiencies in data, thereby allowing better prediction of potential environmental impact of pyrethroid usage and pollution, if any, by these insecticides.
