CYTOGENETIC ASSESSMENT OF PYRETHROID ON BLUE ROCK PIGEONSOMA BHOWMICK AND VIJAY KR. SINGHAbstract The wide use of pyrethroids possesses an inevitable damage to non-targeted organisms/species. Fenvalerate is one such insecticide, whose increased usage can be indirectly harmful to wildlife. In this study effort has been made to detect chromosomal aberrations and single cell DNA strand break (comet assay), on blue rock pigeon (Columba livia) induced by fenvalerate. Sublethal doses of fenvalerate for acute (1 and 2 day) and chronic (15, 30 and 60 days) exposures were given orally. Bone marrow was collected from femur of blue rock pigeon and DNA damage was studied. Significant damage was observed when compared to control birds, which were treated with groundnut oil only. The present study shows genotoxic effect of fenvalerate on non-targeted organisms.
