研究了茚虫威、甲氨基阿维菌素苯甲酸盐、甲氰菊酯三种农药和科云昆虫诱食剂混用后防治烟青虫增效效果,研究结果表明:混用后对防治烟田烟青虫有明显的增效作用,药后1、3、7d的防效比其单用提高4.55～9.09、6.84～10.13、6.24～8.68个百分点,且烟青虫死亡高峰期分别提前了4d、6d、4d。

Three different insecticides such as indoxacarb, emamectin benzoate and fenpropathrin show respec- tively promising synergistic effects in controlling oriental tobacco budworm when mixed with Keyun insect at- tractant. The effects of the insecticides increased by 4.55 -9.09,6.84 -10.13 and 6.24 -8.68 percentage on 1 d, 3d or 7d after application when they are used together with Keyun insect attraetant, compared with those of singly - used insecticide. Moreover, the death peak of tobacco budworm was advanced by 4 days, 6 days and 4 days respectively.
