不同药剂对麦叶蜂的防治效果

Control Experiment of Different Insecticides on Wheat Sawfly

摘要: 2010年在麦叶蜂严重发生的小麦田内进行了不同药剂的防治试验，结果表明：在麦叶蜂3、4龄幼虫高峰期，用48%毒死蜱EC 600~900 g/hm2、50%稻丰散EC 450~1 050 g/hm2、98%晶体敌百750~1 500 g/hm2或4.5%高效氯氟氰菊酯EC 300~450 g/hm2，对麦叶蜂均具有极显著的防治效果，药后16～40 h的杀虫效果均达到95%以上，且各药剂及其用量之间无显著差异。

Abstract: Field experiments of different insecticides on wheat sawfly in wheat heading stage were carried out in 2010. The results showed that in the 3~4 instar larval height stage，when using chlorpyrifos 48% EC 600~900 g/hm2、phenthoate 50% EC 450~1 050 g/hm2、trichlorfon 98% crystal 750~1 500 g/hm2 and 4.5% Lambda-cyhalohrin EC 300~450 g/hm2，the control effect reached above 95% 16~40 h later. The variation analysis of the different processing methods were not significant.
