杜鹃冠网蝽的药剂防治试验

针对5种杀虫剂进行了杜鹃冠网蝽的田间防治试验，结果表明：20％氯氟·毒死蜱微乳剂、10％烯啶虫胺可溶液剂、25％吡蚜酮可湿性粉剂、5％甲维盐水分散粒剂、24％甲氧虫酰肼悬浮剂是防治杜鹃冠网蝽的有效药剂。氯氟·毒死蜱、烯啶虫胺、吡蚜酮、甲维盐为防治杜鹃冠网蝽的首选药剂，药后第14d的防效均在97％以上。其次是甲氧虫酰肼，药后第14d的防效在80％以上。

Chemical Control Experiment on Stephanitis Pyriodes

The results of field efficacy experiment of 5 insecticidesagainst Stephanitis pyriodes show that 20 % chlorpyrifos--lambda cyhalothrin ME, 10% nitenpyram SL,25% pymetrozine WP,5% proclaim WDG and 24 % methoxyfenozide SC are all effective insecticides against Stephanitis pyriodes. Chlorpyrifos--lambda cyhalothrin, nitenpyram, pymetrozine and proclaim are the best choices for controlling Stephanitis pyriodes, and the control effects of the fourteenth day after treatment are all more than 97%. The following choice is methoxyfenozide, and its control effect of the fourteenth day after treatment is more than 80 %.
