几种杀虫剂对黄曲条跳甲的田间防治效果

[目的]筛选黄曲条跳甲的防治药剂。[方法]于2015和2016年采用小区试验研究6种药剂对黄曲条跳甲的防治效果。[结果]5%啶虫脒乳油和15%哒螨灵乳油对黄曲条跳甲的防治效果最好,药后2 d防治效果在90%以上,且持效期较长,药后7 d防治效果仍超过60%;45%马拉硫磷乳油和90%敌敌畏可溶液剂对跳甲的防治效果也较理想,药后2 d防治效果均在80%以上。[结论]试验结果为黄曲条跳甲的有效防治提供了参考。

Field Trials of Several Pesticides against Phyllotreta striolata

[Objective] The aim was to screen out chemicals for controlling Phyllotreta striolata.[Method] We studied control efficacy of several pesticides against Phyllotreta striolata through field trial.[Result] The 5％ acetamiprid EC and 15％ pyridaben EC were most effective against P.striolata with their control efficacy all over 90％.45％ malathion EC and 90％ dichlorvos SL had significant effect on P.striolata,the control efficacy were all over 80％ at 2nd day after treatment.5％ acetamiprid EC and 15％ pyridaben EC had a long term effect in the field with their control efficacy all over 60％ at 7th day after treatment.[Conclusion] The results provide reference for controlling Phyllotreta striolata effectively.
