摘　　要：对3种赤眼蜂在多种不同寄主卵上的寄生特性进行了比较。结果表明:不同蜂种的寄主范围各不相同,其繁殖指数均以在各自的原寄主上为最高。舟蛾赤眼蜂喜好大粒卵,不能寄生玉米螟、二化螟卵块。根据3种赤眼蜂的寄生反应,可将11种寄主卵分为普适、寡适和不适三种类型。Each species of Trichogramma has its own host range. The highest reproductive index occurred in its original hosts respectviely. Trichogramma closterae Pang et Chen prefered to parasite the larger eggs, but never being found in the eggs of Ostrinia furnacalis and Chilo suppressalis. According to the parisitic adaptability, 11 kinds of hosts of 3 species of Trichogramma were divided into three types; poly- adaptative,oligo-adaptative and non-adaptative.
