本文研究了韭菜Allium tuberosum Rottle ex Spreng田常用化学农药辛硫磷、毒死蜱、高效氯氰菊酯、阿维菌素、敌敌畏、三唑酮、菌核净、多菌灵在田间推荐使用浓度及高一倍浓度条件下对Heterorhabditis bacteriophora H06和H.indica LN2线虫存活及感染力的影响,测定了农药与昆虫病原线虫施用间隔时间对线虫感染力的影响。结果显示,高效氯氰菊酯、三唑酮、菌核净和多菌灵对H.bacteriophora H06和H.indica LN2的存活及感染力无显著影响,可与这两种线虫共同使用;敌敌畏对两种线虫有显著致死作用,应严禁使用;辛硫磷、毒死蜱和阿维菌素对H.bacteriophora H06的存活无显著影响,对H.indica LN2具有一定的致死作用,但影响这两种线虫的感染力,这三种农药分别施用10d、10d、20d后则对线虫感染力没有影响,可施用线虫。
In this paper, we studied the recommended concentrations of common pesticides Phoxim, chlorpyrifos, beta-cypermethrin, abamectin, dichlorvos, triadimefon, sclerotinin and carbendazim in the fields of Allium tuberosum Rottle ex Spreng On the survival and infectivity of Heterorhabditis bacteriophora H06 and H.indica LN2 nematodes, and the influence of the time interval between pesticides and entomopathogenic nematodes on nematode infectivity was tested. The results showed that beta-cypermethrin, triadimefon, sclerotinum and carbendazim had no significant effect on the viability and infectivity of H.bacteriophora H06 and H.indica LN2, and could be used together with the two nematodes; Has a significant lethal effect, should be strictly prohibited; phoxim, chlorpyrifos and abamectin on the survival of H.bacteriophora H06 no significant effect on H.indica LN2 has a lethal effect, but affect the infectivity of the two nematodes , The three pesticides were applied 10d, 10d, 20d after the nematode infectivity has no effect, the application of nematodes.
