摘要
对用质型多角体病毒和苏云金杆菌制成的复合微生物杀虫剂,在云南南涧、禄丰县大面积对云南松毛虫和思茅松毛虫的防治效果进行了林内调查、定枝套袋观察和室内药效实验,结果表明,林内、袋内和室内的防治死亡率云南松毛虫分别达86%、79%和49%,思茅松毛虫分别为62%、73%和100%,防治效果十分显著。
The effect of compound microbial pesticide, which was made from CPV and B.t,on controlling Dendrolimus houi and Dendrolimus kikuchii in large areas were observed and analyzed in two counties of Yunnan Province. The results showed that the compound microbial pesticide were very effective on controlling these two Dendrolimus spp., while in the forest the mortality rates of D.houi and D.kikuchii were 86% and 62% respectively.
