摘要：[目的]为了明确松褐天牛肿腿蜂对松褐天牛预蛹和蛹的寄生效果,以期为利用肿腿蜂防治松褐天牛提供更充足的数据支撑。[方法]本研究在室内条件下将不同比例的雌性松褐天牛肿腿蜂接种至松褐天牛预蛹和蛹上,比较寄生效率、子代蜂发育情况的差异,并同时在林间开展松褐天牛肿腿蜂对松褐天牛预蛹和蛹的寄生效果评价。[结果]室内条件下,当蜂虫比为4∶1、6∶1、8∶1时,松褐天牛肿腿蜂对松褐天牛预蛹的寄生率分别为60.71%、85.19%、92.86%,对蛹的寄生率分别为96.67%、96.67%和100%。以预蛹为寄主时,可育出子代蜂的寄主比例不超过50.00%;但寄生松褐天牛蛹时,可育出子代蜂的寄主比例不低于80%。松褐天牛肿腿蜂幼期发育进度并不受母蜂接种比例的影响;但寄生松褐天牛蛹时,子代蜂的发育历期较寄生松褐天牛预蛹时缩短近1 d。母蜂接种比例显著影响子代蜂的数量,当接蜂比例增加时子代蜂的数量也随之增大,但每头寄主上育得肿腿蜂的平均数量均低于100头。子代蜂雄性比例受寄主虫态影响,当寄主为松褐天牛预蛹时,子代蜂雄性比例更大。松褐天牛肿腿蜂按蜂虫比8∶1在林间释放后,对松褐天牛预蛹和蛹的寄生率约为30%。[结论]松褐天牛肿腿蜂可成功寄生松褐天牛的预蛹和蛹,但对松褐天牛蛹的寄生成功率更高。雌蜂高释放比无论是对于室内繁蜂效率还是林间寄生效果都具有促进作用。
[Objective]Sclerodermus alternatusi is an important biocontrol agent of Monochamus alternatus.To understand the parasitism effects of S.alternatusi on pre-pupa and pupa of M.alternatus and provide more sufficient data in supporting the biocontrol of this beetle.[Method]The parasitism efficiency and offspring development were investigated when different numbers of foundresses inoculated on the pre-pupa and pupa of M.alternatus under laboratory conditions.Meanwhile,the parasitism rate of the wasp to M.alternatus pre-pupa and pupa was also evaluated in the field.[Result]The results showed that both the prepupa and pupa of M.alternatus could be parasitized by the bethylid.The parasitism rates to the pre-pupa were 60.71%,85.19%,92.86%,and the parasitism rates to the pupa were 96.67%,96.67%,100%,respectively when Sclerodermus alternatusi-Monochamus alternatus ratio was 4∶1,6∶1,and 8∶1.The proportions of pre-pupa host could produce wasp offspring were less than 50%;while more than 80%pupa host would produce wasp offspring.The developmental progress of the immature stage were not impacted by the foundress densities,but it was shorted nearly one day when the parasitoid used the pupa as host compared to the pre-pupa as host.The numbers of offspring increased with the increasing foundress densities,but the average number of offspring produced from each host was less than 100.In addition,higher proportions of male were produced when the maternal wasp parasitizing M.alternatus pre-pupa.The parasitism rate to the M.alternatus pre-pupa and pupa was about 30%when the parasitoid adults were released with a parasitoid-host ratio of 8∶1 in the field.[Conclusion]S.alternatusi can successfully parasitize the pre-pupae and pupae of M.alternatus but achieve higher fitness in parasitizing the pupae host.High release ratio of female wasp has a promoting effect on both artificial rearing and field parasitism.
