天牛卵长尾啮小蜂生物学研究初报

天牛卵长尾啮小蜂（ＡｐｒｏｓｔｏｃｅｔｕｓｆｋｕｔａｉＭｉｗａｅｔＳｏｎａｎ）是严重蛀干害虫桑天牛（ＡｐｒｉｏｎａｇｅｒｎａｒｉＨｏｐｅ）的重要天敌，此蜂的桑天牛卵内产卵寄生，寄生率高达５０％，经调查发现本寄生蜂的新分布区比记载的［２］由长江流域向北拓宽到长城以北，对长江与长城之间的广大经济林区，具有重要的应用前景。本文较详细地记述了这种寄生蜂的分布、寄生、形态及生活习性等。

Prelimary Study on the Biological Characteristics of Aprostocetus Fukutoi Miwa et Sonan

Aprostocetus fukutai Miwa et sonan was an important natural enemy of Aprionagermari Hope,whichwas a destructive borer pest. The parasitic wasp laid eggs in side the eggs of A. germari Hope,the parasitic rate reached 50%. The investigation showed that the distribution areas of the wasp stretched from the Changjiang River valley recorded formerly to the north of the Great Wall. It had an imoprtant utilization prospect in the vast economic forest areas between the Changjiang River and the Great Wall. The distribution,life cycle,hosts,morphology and living,habites of the wasp were reported in detail in this paper.
