In this paper two - generation reproduction toxicity of fenvalerate, a - cypermethrin, chlorpyrifos, and triazophos was tested in a 21d period with water flea, daphnia magna, . the toxicity indicator included longevity, body length, days to first brood, days to first pregnancy, number of youth per female, intrinsic rate of natural increase ( r ), and number of broods per female. accordingly, the dose - response relations and relations between the chronic responses and enzyme levels were investigated
為了確定水蚤體內生化指標與慢性毒害效應之間的關系，特別是在低濃度暴露狀態下生化指標改變的生物學意義，以便能更準確預測早期農藥對水蚤種群的潛在危害，本文以浙江省常用殺蟲劑氰戊菊酯、高效氯氰菊酯、三唑磷和毒死蜱進行了大型蚤（ d . magna ）的急性和慢性毒性試驗（包括子代水蚤的恢復試驗） 。 -

The phenomenon that ache and bche activity of daphnia magna were higher than controls might result from stimulating actions of pesticides at sub - lethal concetrations. in the recovery test, the body length and reproduction index, such as number of young per female, were reduced for f1 ( 1st ) and f1 ( 3rd ) individuals if the parents ( f0 ) exposed to fenvalerate and a - cypermethrin
子代第一胎f _ 1 （ 1st ）和第三胎f _ 1 （ 3rd ）水蚤恢復試驗中，水蚤的生物學參數及生化指標都有所恢復，但高濃度的農藥經母體轉移到子代體內，對子代水蚤生長、繁殖和體內膽堿酯酶活性仍然存在一定的影響。
