摘 要 ：本文研究了灭幼脲Ⅰ号对油松毛虫室内毒力测定,以及对寄生天敌的影响。在林间用灭幼脲Ⅰ号低容量和超低容量喷雾大面积防治油(赤)松毛虫,并用灭幼脲Ⅰ号对鹌鹑作了毒性试验。结果证明:在林间大面积防治松毛虫后,除对中华草蛉幼虫有影响外,对其他寄生性天敌——松毛虫狭颊寄蝇、黑足凹眼姬蜂无不良影响。对异色瓢虫、蠋蝽等捕食性昆虫亦无不良影响。对白僵菌、粉拟青霉菌在常规使用浓度下无抑菌作用。对鹌鹑也是安全的。因此,灭幼脲Ⅰ号在松毛虫的综合治理中值得推荐。

Abstract:The influence of Diflubenzuron on the natural enemies of two species of pine caterpillars, Dendrolimus tabulaeformis & D.spectabilis, were reported in this paper. According to the results of laboratory experiments and extension tests in the pine forests, the insecticide did not significantly influences on the natural enemies, such as: Carcelia rasella, Casinaria nigripes, Leis axyridis, Arma chinensis, Anastatus sp., Beauveria bassiana, Paecilomyces farinosus, Coturnix japonica, Therefore when the concentrations of diflubenzuron are rational, the use of diflubenzuron for control of the pine caterpillars should be one of the best techniques in the integrated management of these pests.
