摘　　要：南开菊酯是一种新型农药(高效反体氯氰菊酯),具很强的化学稳定性。对草履虫的半致死浓度为5.0mg/L左右,低浓度下对种群生长具有刺激作用,大于0.2mg/L时,毒性效应随农药的增加而提高,4mg/L时开始致死。Nankai-pyrethrin, namely high e(?)ect(?)ve (?) new type pesticide with solid chemical stability. Its halflethal concentration to paramecium is about 5.0mg/kg. Under low concentration, Nankai-pyrethrin stimulates the growth of population. As the concentration is above 0.2mg/kg, toxicity effect becomes more powerful with the increasing use of pesticide; as concentration is 4mg/kg, paramecium begins to die.
