摘要
报道了自山东烟台美国白蛾蛹中养出的啮小蜂一新种———白蛾圆腹啮小蜂AprostocetusmagniventerYangsp.nov.,新种属小蜂总科姬小蜂科啮小蜂亚科长尾啮小蜂属Aprostocetus,群集内寄生于美国白蛾蛹。一头寄主蛹中可出蜂 45～ 62头 ,寄生率为 3 5 % ,雌雄性比 2 6∶1。本种在生物防治上具有一定的利用前景。新种的模式标本保存于中国林业科学研究院昆虫标本馆。
A new species in the genus Aprostocetus is described in present paper:Aprostocetus magniventer Yang (Hymenopetra, Eulophidae:Tetrastichinae). It is an endo-parasitoid in the pupa of Fall Webworm, Hyphantria cunea (Drury) (Lepidoptera:Arctiidae), a serious invasive defoliator species to China. From one host, 45～62 adult wasps were reared out with proportion of female and male 2.6∶1, and parasitic ratio 3.5%. The species has good promising as a biological control agent for suppression of the pest. This unique species is quite different from all other species in the genus Aprostocetus by its great and sub-rounded gaster which is 1.5 times as wide as thorax. The type specimens of the new species are deposited in the Insect Museum of Chinese Academy of Forestry.
