科云昆虫诱食剂与杀虫剂混用防治小麦蚜虫的增效作用研究

Efficiency Test on Keyun Insect Attractant with Pesticides against Wheat Aphids

为验证科云昆虫诱食剂对防治小麦蚜虫的田间示范效果,将其分别与70%吡虫啉水分散粒剂、3%啶虫脒乳油和2.5%高效氯氟氰菊酯乳油混用,进行小麦蚜虫田间防治试验。结果显示,科云昆虫诱食剂均表现出了较好的增效作用,混用施药后1、3、7d的防效与杀虫剂单剂相比,分别提高16.06～17.20个百分点、10.16～10.71个百分点、5.60～6.77个百分点,并使小麦蚜虫死亡高峰期提前了4d,且对小麦安全。可见,科云昆虫诱食剂能够加速害虫死亡,从而有效实现农药减量控害,具有良好的应用前景。

Keyun insect attractant showed good synergistic effects to control wheat aphids when it was mixed with three different insecticides, 70% imdacloprid WG, 30% acetamiprid EC or 2. 5 % lambda-cyhalothrin EC. The effects of insecticides increased by 16.06--17.20,10.16--10.71 ,and 5.60--6.77 percentage points post 1 d,3 d and 7 d when they were used together with Keyun in- sect attractant,compared with those of one single insecticide. Keyun insect attractant also induced the wheat aphid death peak 4 days in advance and it was safe for wheat. In a word,Keyun insect attractant can improve the control effects of pesticides,which has a good application prospect.
