稻螟赤眼蜂(Trichogramma japonicumAshmead)是三化螟卵寄生蜂主要种类之一,分布广而又能寄生二化螟、大螟、稻纵卷叶螟等多种害虫,较在稻田发生的其它赤眼蜂更有利用价值;但不能用蓖麻蚕卵、柞蚕卵来繁殖.为适应稻田治虫需要,在生物防治上发挥“一蜂多用,兼治多虫”的作用,我们于1977年6月至1981年12月,进行了我省稻螟赤眼蜂中间寄主的筛选工作,通过筛选确认大蜡螟Galleria mellonella Linnaeus、小蜡螟Ach-roia grisella F.、稻巢螟Ancylolomia Chry-sographella Kollar、黑条灰灯蛾Creatonotusgangis(Linnaeus)、银纹夜蛾Plusia erio-soma Doubleday、稻螟岭Naranga aenes-cens Moore和沼蝇等的卵皆是稻螟赤眼蜂的
Trichogramma japonicum Ashmead (Trichogramma japonicum Ashmead) is one of the main species of the parasitoid of the rice borer, which distributes extensively and can parasitize many pests such as Sesamia inferens, Sesamia inferens and Cnaphalocrocis medinalis, Trichogramma more value; but can not be castor silkworm eggs, tussah eggs to breed .In order to adapt to the needs of rice field pest control, biological control play “a bee multipurpose, and rule multi-insects” effect, we in June 1977 By December 1981, we carried out the screening of the intermediate hosts of Trichogramma ostriniae in our province. The screening of Galleria mellonella Linnaeus, Ach-roia grisella F., Ancylolomia Chry-sographella Kollar, Creatonotus ganglis (Linnaeus), Plusia erio-soma Doubleday, Naranga aenes-cens Moore,
