| 摘 要： | 棉田四种常用杀虫剂对玉米螟赤眼蜂不同虫态的杀伤力差异显著。溴氰菊酯、氰戊菊酯、久效磷、甲胺磷对玉米螟赤眼蜂成虫的杀伤力均很强；溴氰菊酯和甲胺磷对玉米螟赤眼蜂卵至蛹各个虫态的杀伤力较强；而氰戊菊酯对卵、久效磷对幼虫有较强的杀伤力。久效磷对玉米螟赤眼蜂成虫的残留毒杀力最强。玉米螟赤眼蜂成虫是玉米螟赤眼蜂一生中对农药最敏感的时期，其次是卵和幼虫，而预蛹和蛹耐药性较强。

| Abstract: | Evidences show that toxicity of 4 kinds of insecticicles are far different on different stages of Trichogramma ostriniae Panget Chen. They all have strong toxicity on the adults of T. ostriuiae.Deltamethr in and methamidophos are strouger on eggs. larvae. prepupas and pupas, while fenvalerate is on eggs and monocrotophos is on larvae. Monocrotophos bas the strongest remnant toxicity on the adults of T. ostriniae and the adults are most susceptible to the insecticides in their whole lives.Eggs and larvae are less susceptible. The prepupas and pupas have strong resistance to the inseticides in theirwhole s tages, |
