摘要
为筛选对斜纹夜蛾生物活性较高的杀虫剂配比,从而为生产防治和开发复配杀虫剂提供理论依据。采用8种杀虫剂的两元复配混合物对斜纹夜蛾4龄幼虫进行毒力测定。结果表明:在杀虫剂复配组合中,甲氰菊酯与氟铃脲1∶7.5,氟铃脲与甲维盐1∶1、5∶1和15∶1,甲氰菊酯与乙酰甲胺磷1∶7.5,毒死蜱与阿维菌素1∶1、5∶1、10∶1、12.5∶1、15∶1和17.5∶1等均对斜纹夜蛾具有明显的增效作用;高效氯氰菊酯与氟铃脲、乙酰甲胺磷与溴氰菊酯的复配组合对斜纹夜蛾表现出明显的拮抗作用。
Toxicity test to the 4th instar larvae of Prodenia litura applied by binary combination of 8 insecticides was conducted to screen the optimal ratio of insecticides with highest biological activity to P.litura and provide reference for insecticides prevention and development of insecticides combination.The results showed that 1∶7.5 of fenpropathrin with hexaflumuron,1∶1,5∶1 and 15∶1 of hexaflumuron with emamectin benzoate,1∶7.5 of fenpropathrin with acephate,and 1∶1,5∶1 and 10∶1,12.5∶1,15∶1 and 17.5∶1 of chlorpyrifos with abamectin etc.could obviously improve the control effect to P.litura.The combination of beta-cypermethrin with hexaflumuron,acephate with deltamethrin had obvious antagonism to P.litura.
