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.
According to the experience of our predecessors, this experiment was conducted in Xiamen Fujian in 2004-2007 to prevent and control beekeeping and to demonstrate the promotion experiment.The results showed that: The method of releasing bee per plant was better than that of other plants. The corrected parasitism rates were 31.27% and 30.99% respectively, which was significantly higher than 11.36% of the center’s beekeeping method. The best time for beekeeping was from June to July , At this time the temperature between the forest is about 27 ℃, suitable for Trichogramma activity, but also young days, easily parasitic; put bee density to bee ratio is 3: 1. , The application of Tricholoma matsutake Monochamus alternatus Monochamus larvae feasible, parasitic effects are stable at 20%.
