氨基甲酸酯类杀虫剂及其与阿维菌素的混配制剂对美洲斑潜蝇(Diptera:Agromyzidae)的防治效果

Control of Liriomyza sativae Blanchard (Diptera: Agromyzidae) with Carbamate Insecticides and Abamectin

测定了扑蚜威、速灭威、灭蚜威、间乙威等9个氨基甲酸酯类化合物及其 与阿维菌素混剂对美洲斑潜蝇的田间药效，结果发现，当施用有效量075 kg/hm2时，氨 基甲酸酯类单剂对美洲斑潜蝇的防效在75%～92%之间，而扑蚜威、速灭威、灭蚜威与阿维菌 素混剂对该蝇的防效可达85%～92%。表明，氨基甲酸酯类化合物与阿维菌素混配对美洲斑潜 蝇田间防效、速效性均较好，且成本显著降低。

o -metolcarb, metolcarb, p -metolcarb, 3-ethylphenyl - N -methyl carbamate, isoprocarb, Hercules 5727, β -carbaryl, xylycarb and XMC applied at 0.75 kg/hm2 showed a larvicidal activity of 75%～92% in the fie ld trials for leaf miner ( L.sativae )control.And o -metolcarb+abamectin ( combi.),metolcarb+abamectin (combi.), p -metolcarb+abamactin (combi.) and iso procard+abamactin (combi.) applied at 0.75,0.5625 and 0.375 kg/hm2 showed a control efficacy of 85%～92%. The efficacy of abamectin after 3 d was only 65% ～67% but up to 89%～91% after 7 d. The mixed formulation possesses a quick acti on, good residual performance but relatively low cost.
