摘要
玉米赤眼蜂自身密度干扰效应显著。在同一寄主（米蛾卵）密度条件下，干扰效应符合Hassell模型。在不同寄主密度条件下，赤眼蜂的寄生功能反应符合Beddington模型，自身密度对寄生率以及个体生殖力也存在干扰效应。
The intefference efficiency of Trichogramma ostrinta Pang et Chen to itself density is significant, and will effect parasitism and individual fecundity of the parasitoid. At the same host density, the enterference effi-ciency fits to the Hassell model. And at the range of defferent host density, the parasitic functional repense of T. ostrinia is conformed to the Beddington model.
