摘　　要：管氏肿腿蜂是有效防治松墨天牛幼虫的重要寄生性天敌.根据前人经验,本试验于2004-2007年在福建厦门进行林间放蜂防治和示范推广试验.结果表明:林间放蜂方法以每株放蜂法和隔株放蜂法为优,校正寄生率分别达31.27%和30.99%,明显高于中心放蜂法的11.36%;最佳放蜂时间为6-7月份,此时林间温度为27℃左右,适于管氏肿腿蜂活动,也是天牛幼龄期,易于被寄生;放蜂密度以蜂虫比为3∶1为宜.林间示范推广试验效果表明,应用管氏肿腿蜂防治松墨天牛幼虫切实可行,寄生效果均稳定在20%以上.Scleroderma guani Xiao et Wu is an important natural enemy in biocontrolling Monochamus alternatus Hope. S. guani was released to pine forest in Xiamen for controlling M. alternatus. The results showed that it was better to release S. guani on every tree or every other tree, whose corrected parasitism rates were 31.27% and 30.99% respectively. These were significantly higher than releasing S. guani at the center of pine forest, whose corrected parasitism rate was only 11.36%. The best time of releasing S. guani was June and July, when the temperature in forest was around 27 ~C and M. alternatus was larval instar, and the optimal parasitoid- host ratio was 3： 1. The high parasitism rate of releasing S. guani to 266 hm2 pine forest for biocontrolling M. alternatus proved that controlling larva of M. alternatus by releasing S. guani to forest was feasible, in which the average parasitized rate was over 20%.
