25%环氧虫啶可湿性粉剂对绿盲蝽的防治效果及对天敌的安全性评价

Control Efficacy of Cycloxaprid 25% WP to Apolygus lucorum and Evaluation of Its Safety to Natural Enemy

[目的]明确25%环氧虫啶WP对棉田绿盲蝽的防治效果和对天敌瓢虫的安全性。[方法]利用田间试验评价了25%环氧虫啶WP和5种对照药剂对绿盲蝽的种群控制作用。[结果]25%环氧虫啶WP 12.5 g a.i./hm^2处理对绿盲蝽成虫和若虫具有较高的防治效果,分别达到98.54%和83.49%,显著高于5.7%甲维盐SC,但与其他对照药剂无显著差异;且该药剂对棉田捕食性天敌瓢虫具有一定的安全性。[结论]25%环氧虫啶WP可作为一种综合防治棉田绿盲蝽的轮换药剂,大面积推广应用。

[Aims] The paper aims to verify the control effect of cycloxaprid 25% WP to Apolygus lucorum and its safety to ladybugs in cotton field. [Methods] The population control efficacy of cycloxaprid 25% WP and 5 control pesticides was evaluated in the trails. [Results] The results indicated that the control effect of cycloxaprid 25% WP to A. lucorum adults and nymphs was 98.54 and 83.49%, respectively, significantly higher than emamectin 5.7% SC, and there was no significant difference with other control agents. Furthermore, cycloxaprid was safe to the ladybugs in cotton field.[Conclusions] Cycloxaprid 25% WP was regarded as an optional pesticide for comprehensive management to A.lucorum in cotton field, and could be utilized on a wide scale in production agriculture.
