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 egg-laying 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 egg-laying. 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.
本研究调查了合成拟除虫菊酯氯氰菊酯对黑腹果蝇某些发育特征的影响。实验前测定了这种杀虫剂的致死浓度。通过将氯氰菊酯溶液添加到培养基中，以营养方式施用于黑腹果蝇。对照组未施用此类物质。我们的目的是通过观察成年雌蝇的产卵率、卵的发育以及幼虫的发育，来查明是否发生任何发育毒性作用，以及如果发生，在哪个阶段发生。结果表明，产卵率没有显著差异。然而，卵发育率的下降表明卵和早期胚胎阶段对毒性作用敏感。在三龄幼虫中未观察到相同的毒性作用。观察到毒性作用在发育早期最强。
