短须突瓣叶蜂是近年来危害柳树的一种新害虫,选用7种杀虫剂对短须突瓣叶蜂幼虫进行室内毒力测定,筛选出5种杀虫剂开展田间防治试验。结果表明:供试杀虫剂对短须突瓣叶蜂的毒力大小依次为:1.8%阿维菌素乳油>10%阿维·毒死蜱乳油>4.5%高效氯氰菊酯乳油>40%丙溴磷乳油>4.5%联菊·啶虫咪微乳剂>1%苦参碱可溶性液剂>4%甲维·氟铃脲微乳剂。田间药效试验结果显示,施药24h后,1.8%阿维菌素乳油、10%阿维·毒死蜱乳油和4.5%高效氯氰菊酯乳油是防治短须突瓣叶蜂的有效药剂。
Short-tootubular leaf bee is a new pest that endangered willow in recent years. Seven kinds of insecticides were used to determine the indoor toxicity of the short-beagles parasite Larvae, and five kinds of pesticides were screened to control the field. The results showed that the virulence of the tested insecticides against T. mallard were 1.8% abamectin EC 10% AVV chlorpyrifos 4.5% beta-cypermethrin 40% profenofos > 4.5% Rhodamine micro-emulsion> 1% matrine soluble liquid> 4% of the methyl-hexaflumuron microemulsion. The results of field efficacy test showed that 1.8% abamectin EC, 10% avicel chlorpyrifos EC and 4.5% beta-cypermethrin EC were effective agents for the control of Brachymystinae.
