Abstract
This study investigated the effects of cypermethrin a synthetic pyrethroid on some developmental features of Drosophila melanogaster Before the experiment the lethal concentration of this insecticide was determined Cypermethrin solution was applied to Drosophila melanogaster by means of nutrition by adding it to the culture medium In the control group no such substance was applied Our aim was to find out whether any developmental toxic effects occur and if they do during which stage by observing the rates of egglaying of adult females the development of eggs and the development of larvae The results showed that there was no significant difference in the rates of egglaying However the decrease in the rate of egg development revealed that eggs and early embryonic stages were sensitive to toxic effects The same toxic effect was not observed in third instar larvae The toxic effect was observed to be strongest in the early stages of development
