24种杀虫剂防治白刺古毒蛾药效试验

通过24种杀虫剂田间药效试验,筛选出10种对白刺古毒蛾(Orgyia antiqua)具有优良防效的杀虫剂，即类产碱SC、10%天罗地网EC、25%黑光灯EC、4.5%氯氰菊酯EC、草毒蛾SC、2.5%敌杀死EC、3%金永安EC、5%速杀星EC、1.8%阿维菌素EC和10%金大地WP，防效均在90%以上，其中类产碱SC、草毒蛾SC、1.8%阿维菌素EC具有低毒、高效、持效期长等特点,可作为古毒蛾防治首选杀虫剂使用。10%天罗地网EC、25%黑光灯EC、4.5%氯氰菊酯EC、2.5%敌杀死EC、3%金永安EC、5%速杀星EC、10%金大地WP具有防效快特点，可与类产碱SC、草毒蛾SC、1.8%阿维菌素EC在古毒蛾暴发年份交替使用或混合使用，以延缓抗性的产生。

The control effectiveness of 24 pesticides on Bazaria turensis

A field experiment was conducted to select the optimal pesticides from 24 pesticides for control Bazaria turensis.This study showed 10 pesticides among 24 pesticides performed well,and they were Pseudomonas pseudoalcaligenes SC,10% Cyfluthrin EC,25% Profenophos EC,4.5% Cypermethrin EC,Gynaephora ruoergensis chou et yin Nuchear polyHedrosis rirus SC,2.5% Deltarmethrin EC,3% β-Cypermethrin EC,5% β-Cypermethrin-Admire EC,1.8% Avermectin EC and 10% Imidacloprid WP,in which Pseudomonas pseudoalcaligenes SC,G.ruoergensis chou et yin Nuchear polyHedrosis rirus SC,and 1.8% Avermectin EC showed a lower toxicity and higher efficiency and long effective period,and they had the priority for controlling the larva of B.turensis.The 10% Cyfluthrin EC,25% Profenophos EC,4.5% Cypermethrin EC,2.5% Deltarmethrin EC,3% β-Cypermethrin EC,5% β-Cypermethrin-Admire EC and 10% Imidacloprid WP showed a faster control effect on B.turensis.Application of selecting 10 pesticides together postponed the time of pesticides resistance of B.turensis.
