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

摘要: 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。

Abstract: 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.
