黄曲条跳甲的化学防治研究

Chemicals used for controlling Phyllotreta striolata(F.)

黄曲条跳甲化学防治现状调查表明,黄曲条跳甲化学防治过程中存在的虫态选择、防治适期、药剂种类和防治方法等4方面的问题,从而对化学防治效果产生重要影响。化学杀虫剂的室内筛选和田间药效试验结果表明,48%乐斯本EC、40%辛硫磷EC、80%敌敌畏EC、20%好年冬EC、24%灭多威SP、18%杀虫双SL等药剂对黄曲条跳甲成虫有较好的室内毒杀效果和田间药效,48 h内均能有效控制黄曲条跳甲的为害。

The application time, stage, insecticide and method are important factors in chemical control of Phyllotreta striolata （F）. The lab and field toxicity tests showed that 480% EC of chlorpyrifos, 40% EC of phoxim, 80% EC of dichlorvos, 200% EC of carbosulfan, 240% SP of methomyl or 18% SL of bisultap could effectively control the pest in 48 hours.
