１９８７～１９９２年连续６年研究结果表明，白跗平腹小蜂Ａｎａｓｔａｔｕｓａｌｂｉｔａｒｓｉｓ对马尾松毛虫Ｄｅｎｄｒｏｌｉｍｕｓｐｕｎｃｔａｔｕｓ、柳杉毛虫Ｄｅｎｄｒｏｌｉｍｕｓｌａｔｉｐｅｎｎｉｓ、水青蛾Ａｃｔｉａｓｓｅｔｅｎｅｎｉｎｇｐｏａｎａ等１３种主要森林害虫卵有较明显的抑制作用。在林间，该蜂对马尾松毛虫第１、２代卵的自然抑制力分别力１６．５５％和２２．２９％，对柳杉毛虫越冬代卵的自然抑制力为２３．４５％；对水青蛾第１、２代卵的抑制力分别力５．４９％和２．６３％；在林间，人为释放白跗平腹小蜂对第１代马尾松毛虫卵的校正抑制力为３３．５％，在室内１２．３～２８℃范围内，每头雌峰对马尾松毛虫、水青蛾和柞蚕剖腹卵的日破坏数（寄生数）分别力１５、１８和２６粒，一生破坏数分别为５６、９１和２０８粒。即使虫卵即将孵化，该峰同样亦能寄生，并羽化出正常的子代白跗平腹小蜂。
The results of six consecutive years from 1987 to 1992 showed that Anastatusalbitarsis had obvious inhibitory effects on Dendrolimus punctatus, Dendrolimus latipennis and Actiasseteneningpoana of Dendrolimus punctatus in 13 major forest pests. In the forest, the natural inhibitory power of the bee on the first and second generation eggs of Masson Dendrolimus were 16.55% and 22.29%, respectively, and the natural inhibitory force on the overwintering egg of cedar caterpillar was 23.45% The inhibitory power of the first and the second generation eggs of the hydatid moth were 5.49% and 2.63%, respectively. In the forest, the corrected inhibitory power against the first generation P. massoniana eggs was 33 .5%, respectively. Within the range of 12.3 ~ 28 ℃, the number of daily destructive (parasitic) days of each peak on the number of parasitized eggs of Dendrolimus punctatus, Hydatidorpus and tussah were 15, 18 and 26, 56, 91 and 208 respectively. Even if the eggs are about to hatch, the peak can also parasitize, and the emergence of the normal offspring Pampawaya.
