在山东青州以西葫芦为试验害虫寄主 ,测定了毒死蜱、三唑磷、乙酰甲胺磷、辛硫磷、马拉硫磷对美洲斑潜蝇幼虫LiriomyzasativaeBlanchard的田间防效。毒死蜱 (2 4g (a .i.) 667m2 )、三唑磷 (1 0g (a.i.) 667m2 )、乙酰甲胺磷 (2 0g (a .i.) 667m2 )第 3~ 7d校正防效为 97 0 9%~ 97 1 4% ,86 80 %~87 0 4% ,85 99%~ 86 2 5 %。此 6个处理药效顺序为毒死蜱 >三唑磷 >乙酰甲胺磷 (2 0g(a.i.) 667m2 )>乙酰甲胺磷 (1 5g(a.i.) 667m2 ) >辛硫磷 >马拉硫磷。在河南洛阳以甘蓝为试验害虫寄主 ,乙酰甲胺磷 (1 5g(a.i.) 667m2 )、敌敌畏 (2 5g(a.i.) 667m2 )、敌百虫 (4 5g(a .i.) 667m2 )对美洲斑潜蝇幼虫第 7d校正防效分别为 76 98% ,82 42 % ,71 1 1 %。毒死蜱对在不同寄主上美洲斑潜蝇的防效均较好
In Qingzhou, Shandong Province, as the host of the pest tested, the control efficacy of chlorpyrifos, triazophos, acephate, phoxim and malathion on Liriomyza sativae Blanchard was studied. The control efficacy of chlorpyrifos (2 4g (a. I.) 667m2), triazophos (10g (ai) 667m2) and acephate (20g 9% -97 1 4%, 86 80% -87 0 4%, 85 99% -86 2 5%. The order of the six treatments was chlorpyrifos> triazophos> acephate (20g (a.i.) 667m2)> acephate (15g (a.i.) 667m2)> phoxim> malathion. In Luoyang, Henan Province, the host of test pests were probiotics such as acephate (15g (ai) 667m2), dichlorvos (25g (ai) 667m2) and trichlorfon On the 7th day, the corrected control efficacy of the latent fly larvae was 76 98%, 82 42% and 71 11% respectively. Chlorpyrifos has a good control effect on different hosts on the leaf blotch
