Acute and toxic effects of fenitrothion on eggs and larvae of Macrobrachium lamerrii have been studied. The hatching success of the eggs is not affected when berried females are exposed to fenitrothion. No drastic changes in egg production are seen at sublethal levels, while at higher concentrations females abort their eggs. The first-stage larvae hatching in subacute chronic exposure are not morphologically abnormal. The rate of heart pulsation in embryos and larvae increased under pollutant stress. Larvae are highly susceptible and death rate of larvae does not increase during molt period. On chronic exposure there are drastic changes in the gonads of M. lamerrii.
研究了杀螟硫磷对罗氏沼虾卵和幼体的急性和毒性作用。抱卵雌虾暴露于杀螟硫磷时，卵的孵化成功率不受影响。在亚致死水平下，产卵量未见剧烈变化，而在较高浓度下，雌虾会弃卵。亚急性慢性暴露下孵化出的第一期幼体在形态上无异常。在污染物胁迫下，胚胎和幼体的心跳速率增加。幼体高度敏感，且在蜕皮期幼体死亡率未增加。长期暴露后，罗氏沼虾的性腺出现剧烈变化。
