江西马尾松毛虫的抗药性及克服抗性发展对策

The Insecticide-Resistance of Dendrolimus punctatus in Jiangxi Province and It's Management Strategy

根据对江西部分林区马尾松毛虫毒力测定结果分析,江西林区马尾松毛虫对功夫菊酯和多来保敏感,对氯氰菊酯和氰戊菊酯的耐药力有所提高,高安、贵溪等林区马尾松毛虫对溴氰菊酯产生了抗药性。在此基础上提出了克服马尾松毛虫抗性发展的对策。

The results of toxicological experiments to Dendrolimus punctatus in a parts of forest areas in Jiangxi province showed that Dendrolimus punctatus in Jiangxi extremely sensitive to trobon and cyhalothrin, and were rather tolerant to fenvalerate and cypermethrin, But the populations of Dendrolimus puactatus in Gaoan and Guexi developed resistance to deltamethrin. On the basis, the strategy of resistance manegement were been put up.
