【摘要】 采用菜粉蝶(Pierisrapae)颗粒体病毒和芹菜夜蛾(Anagraphafalcifera)核型多角体病毒制剂及两者的混合制剂对菜粉蝶和小菜蛾(Plutellaxylostella)进行了田间防治试验.结果表明,两种病毒制剂对菜粉蝶具有良好的防治效果,15d最终防效在93%以上;芹菜夜蛾核型多角体病毒制剂及两者的混合制剂对小菜蛾也有良好的防治效果,15d最终防效在89%以上,其效果均分别优于化学农药毒死蜱88%和84%的防效.更多还原

【Abstract】 <Abstrcat> Pesticides of Pieris rapae granulosis virus (PrGV) and Anagrapha falcifera nuclear polyhedrosis virus (AfNPV), and their mixture were used to control Pieris rapae and Plutella xylostella in the field. The results showed that both PrGV and AfNPV had high effects against Pieris rapae, which were over 93% at the 15th day after treatment. AfNPV and the mixture of PrGV and AfNPV were also with high effects against Plutella xylostella,the average control effects were over 89% at the 15th day after treatment. In addition, both pesticides had higher effects than those of Chlorpyrifos treatment against Pieris rapae and Plutella xylostella, which were 88% and 84% respectively.更多还原
