摘  要:
在7月上旬,将80%敌敌畏稀释成4种浓度,对野外馒头柳上的柳蓝叶甲进行田间对比试验,结果表明:不同浓度配比其虫口减退率有显著差异,随着浓度增加,防治效果也逐渐提高;从保护天敌和避免害虫产生抗药性等综合因素考虑,采用1∶500倍的80%敌敌畏防治柳蓝叶甲较适宜。

摘  要:
In early July,80% dichlorvos was diluted to four concentrations,Plagiodera versicolorain the field were conducted comparison experiments.Result shows that:decrease rate of Plagiodera versicolora under different concentration ratios have significant differences.The control effect gradually increases with the increase of the concentration.From the viewpoint of protecting natural enemies and avoid pest resistance,adopting 80% dichlorvos(1:500times)to prevent Plagiodera versicolorais more appropriate.
