五种农药对露尾甲的防治效果

The Control Efficiency of Five Insecticides to Nitidulid Beetles

以高效氯氰菊酯、毒死蜱、苦皮藤素、阿维菌素、三唑磷为母液,研究其对青海省油菜露尾甲防治效果。结果表明:农药处理7d后,油菜露尾甲的为害率均有所下降,其中三唑磷和高效氯氰菊酯处理后为害率下降较高,分别达71.13%和76.08%;而苦皮藤素处理后为害率下降最低,只有19.66%;高效氯氰菊酯和三唑磷的为害校正减退率分别为83.42%和79.99%,表明三唑磷和高效氯氰菊酯在防治油菜田中的露尾甲上有一定的应用前景。

Taking Beta-cypermethrin,Chlorpyrifos,Celangulin,Abamectin and Triazophos as mother liquor,the effects of them on controlling Nitidulid beetles were studied.The results showed that the destroy ratioes were decreased after spraying five insecticides within 7days.The ratios of Triazophos and Beta cypermethrin were 71.13% and 76.08%,respectively.But it was only 19.66%after celangulin treat.The destroying corrected decrease ratio of Beta cypermethrin and Triazophos were 83.42% and 79.99%,respectively.So there was certain applying prospect to control Nitidulid beetles with Beta cypermethrin and Triazophos in fields.
