摘　　要：采用3种不同的方法测定了5种常用杀菌剂对天敌胡瓜钝绥螨Neoseiulus cucumeris(Oudemans)的影响。结果表明5种杀菌剂中,86.2%铜大师可湿性粉剂800～1200倍对胡瓜钝绥螨有较低的影响,喷雾法测定最高浓度800倍校正死亡率为15.00%,而让胡瓜钝绥螨取食经86.2%铜大师可湿性粉剂各浓度药液处理过的山楂叶螨Amphitetranychus viennensis(Zacher)均无二次中毒现象,80%代森锌可湿性粉剂、80%大生M-45可湿性粉剂、50%代森锰锌可湿性粉剂和50%普雅图可湿性粉剂在3种试验方法中各浓度对胡瓜钝绥螨死亡率均与清水对照相当,因此释放捕食螨生防园防治病害可选用对胡瓜钝绥螨影响小的80%代森锌可湿性粉剂800～1000倍、80%大生M-45可湿性粉剂500～600倍、50%代森锰锌可湿性粉剂600～800倍、86.2%铜大师可湿性粉剂1200～1500倍、50%普雅图可湿性粉剂800～1000倍。In this paper, the effect of five germicide to Neoseiulus cucumeris（Oudemans） was tested by three different methods. The results showed that 86.2% cuprous oxide WP had little toxicity to Neoseiulus cucumeris （Oudemans）. There was no toxicity to Neoseiulus cucumeris （Oudemans） after eating Amphitetranychus viennensis（Zacher）, Which were treated by 86.2% cuprous oxide WP. 80% zineb WP, 80% mancozeb M-45 WP, 50% mancozeb WP and 50%Puyatu （carbendazim and thiram）WP without toxicity to Neoseiulus cucumeris （Oudemans）, so that we can use 86.2% cuprous oxide WP at 1 200-1 500 times, 80% zineb WP at 800-1 000 times, 80% mancozeb M-45 WP at 500-600 times, 50% mancozeb WP at 600-800 times, 50% Puyatu （carbendazim and thiram） WP in the releasing predatory mite orchard.
