ABSTRACT
Pesticides are major contaminants of our environment and pose a serious threat to non target organisms. The present experimental design aims to study the toxic effect of Flash on the embryo of chick treated at the post organogenesis stage of its developmental period. Fertilized eggs of pure breed (BV 300) of chick were immersed in low, moderate and high concentrations of the toxicant for one hour on day 7 of incubation and recovered on day 15 to observe skeletal development. The treated group’s revealed malformations at all doses. The mortality rate was found to increase with significant decrease in wet body weight with increase in the dose. The pesticide caused overall reduction in ossification of skeleton; with significant malformations at only high dose, and in thoracic and caudal vertebrae. Present findings show that Flash is a potent teratogenic with reference to avian species. Keywords: Chick embryo .Morphology. Quinalphos. Skeleton.
