摘　　要：白蛾周氏啮小蜂为美国白蛾的重要寄生性天敌,具有寄生率高、繁殖能力强、雌雄性比大且替代寄主易得等特点。本文旨在探索白蛾周氏啮小蜂在湖北人工繁育的可能性,通过前期结果平均寄生率71.56%、平均羽化量6064.8头,可知白蛾周氏啮小蜂在湖北进行人工繁育是可行的,为后期大规模繁育提供了必要条件。Chouioa cunea is the important parasitoid of Hyphanta cunea,it has the characteristics of high parasitic rate,reproductive capacity and ratio of fem-ale to male,finally easy to replace the host.The purpose of the authors is explored the possibility of artificial breeding of C.cunea in Hubei province.According to the results of experiments,the average parasitization rate is 71.56%and the average amount of eclosion is 6064.8,The results showed that it was feasible to carry out artificial breeding in Hubei province,which provided necessary conditions for later large-scale breeding.
