本文报道了以新型杀虫剂吡虫啉为主剂， 通过增效技术将之加工成３ ％ 吡蚜灵乳油新制剂，对麦长管蚜、棉蚜和苹果黄蚜的共毒系数达２２１ ～９３４；稀释３０００ 倍喷雾，对３ 种蚜虫的防效均达９５ ％ 以上，持效期超过１５ｄ ，优于吡虫啉的常用加工制剂。
In this paper, a new insecticide imidacloprid-based agent was developed to process 3% imidacloprid-based EC cream by synergistic technology. The co-toxicity coefficients of imidacloprid, cotton aphid and apple aphid were 221 ~ 934 ; 3000 times diluted spray, the control effect of three kinds of aphids were more than 95%, persistence of more than 15d, better than imidacloprid commonly used processing formulations.
