研究了有机氯杀虫剂硫丹（噻丹）对黑腹果蝇（Drosophilamelanogaster）4个形态性状（翅长、胸长、眶鬃数和胸侧鬃数）的表型和遗传变异的影响。此外，这种农药对发展的稳定性的影响进行了估计，作为波动的不对称性的双边性状。在添加硫丹的培养基上，形态性状的表型变异显著较高。压力和对照样品之间的波动不对称性没有差异被发现。与对照条件下的相应方差相比，在含有硫丹的培养基上饲养的果蝇的形态测量性状的双系方差显著更高。本文讨论了利用形态和部分性状的波动不对称性和表型变异作为昆虫种群环境胁迫指标的有效性。
The effects of chlorine-organic insecticide endosulfane (thiodan) on phenotypic and genetic variation in four morphological traits of Drosophila melanogaster(wing length, thorax length, the number of orbital bristles and the number of sternopleural bristles) were examined. In addition, the effect of this pesticide on stability of development measured as fluctuating asymmetry of bilateral traits was estimated. On the medium with endosulfane, phenotypic variation of morphometric traits was significantly higher. No difference in fluctuating asymmetry between the stressed and the control samples was found. The among-line variance of morphometric traits of flies reared on the endosulfane-containing medium was significantly higher as compared to the corresponding variance under control conditions. The efficiency of using fluctuating asymmetry and phenotypic variation of morphometric and meristic traits as indicators of environmental stress in insect populations is discussed.
