几种拟除虫菊酯杀虫剂对粘虫的杀卵活性研究

Study on the Ovicidal Activity of Some Pyrethroid Pesticides Against Army Worm(Pseudaletia separata)

室内采用浸渍法测定了拟除虫菊酯对粘虫杀幼虫和杀卵的活性，结果说明氯氟氰菊酯、溴氰菊酯杀幼虫活性比杀卵活性高。

Ovicidal and larvicidal activities of some pyrethroid pesticides in the laboratory were tested to army worm(Pseudaletia separata)with immersion method.The results showed that the larvicidal activity of pyrethroid(decamethrin or cyhalothrin)is higher than its ovicidal activity.The efficacy of six pyrethroids for mortality of egg death was in the following order:decamethrin >alphamethrin>cyhalothrin>cypermethrin>fenpropanate>fenvalerate.
