摘要: 描述了从美国白蛾蛹中养出的一种啮小蜂新种-白蛾黑棒啮小蜂 Tetrastichus septentrionalis sp. nov., 属啮小蜂属Tetrastichus黑棒啮小蜂种团(howardi-group)。该新种在我国北方美国白蛾发生区分布普遍,也分布韩国。在美国白蛾越冬蛹中及夏季蛹中的寄生率一般为12%~24%,每头寄主蛹出蜂数为78~182 头,雌雄性比为10∶1。在生物防治上具有很好的利用前景。

Abstract: A new species, Tetrastichus septentrionalis sp. Nov., reared from pupae of fall webworm, Hyphantria cunea, from Tianjin, Hebei, Shandong is described. The parasitoid distributes in all areas where the pest outbreaked in China and in Seoul, Korea. In general, its parasitic rate in pupae of the moth was 12%~24%, and 78~182 wasps were reared from one host pupa, the female and male ratio was 10∶1. The species has a bright prospect as a biocontrol agent.
