科云昆虫诱食剂与杀虫剂混用防治大白菜制种田蚜虫的增效作用研究

Study on Synergetic Efficacy of Keyun Insect Attractant Combined with Pesticides Against Aphid in Chinese Cabbage Seed Production

高效氯氰菊酯、啶虫脒、阿维菌素3种农药和科云昆虫诱食剂混用,对于防治大白菜制种田蚜虫有明显的增效作用,药后1、3、7d的防效比其单用提高8.64～11.77、1.88～8.77、4.34～9.34个百分点,且蚜虫死亡高峰期分别提前了2、4、2d。

Three different insecticides such as Lambda-cyhalothrin,Imdacloprid and Avermectin showed respectively promising synergistic effects in controlling aphid of Chinese cabbage seed production when mixed with Keyun insect attractant,The effects of the insecticides increased by 8.64-11.77、 1.88-8.77 and 4.34-9.34 percentage on 1d,3d or 7d after application when they were used together with Keyun insect attractant,compared with those of singly-used insecticide.Moreover,the death peak of aphid was advanced by 2 days,4 days and 2 days respectively.
