摘　　要：江西省各地马尾松毛虫抗药性监测结果表明，马尾松毛虫对氰戊菊酯和氯氰菊酯的耐药力均有不同程度的提高，尚属耐药力的差异。贵溪、高安林区马尾松毛虫对溴氰菊酯则已发展到低抗水平，抗性指数分别为５．７和５．９。５种增效剂进行增效作用研究，Ｐｂ和ＳＶ＿１的增效作用较强，显著降低拟除虫菊酯的用量，可延缓抗性的发展。The contact toxicities of several pyrethroids to the populations of Dendrolimus punctatusin Jiangxi province were tested by using microcapillary topical application methods. The re-sults showed that the tolerence of the popufations of Dendrolimus punctatus in Jiangxi to fen-valerate and cypermethrin was increased variously,belonging to tolerant difference,But theresistence level of the populations in Guixi and Gaoan to deltamethrin had developed to low-resistence. The resistence index were 5.7 and 5.9,respectively. The synergism of five synergists was tested in laboratory.The results showed that theeffects of Pb and SV_1 were much stronger than those of the other three synegists. Mixedwith Pb and SV. the applying ammounts of pyrethroids could be reduced greatly and the de-velopment speed of insecticide-resistance of Dendrolimus punctatus to pyrethroids could beslowed down.
