摘　　要：在１７～３３℃范围内，玉米螟赤眼蜂（Ｔｒｉｃｈｏｇｒａｍｍａｏｓｔｒｉｎａｅ）在米蛾卵上的寄生功能反应，均符合Ｈｏｌｌｉｎｇ（Ⅱ）型模型。不同温度对功能反应多数有明显影响，以３ｏ℃条件下的最大寄生量为最高（Ｎａｍａｘ＝２９．９）。寄生率、温度及寄主密度三维关系分析显示，在本试验温度条件下，温度对寄生率的影响尚不及寄主密度的影响大。Under the temperatures of 17～33℃,the functional response of Trichoqrammaostriniae Pang et Chen on the host egg of Coroyra cephalomica(Staiuton),was simu-lated with the Holling(Ⅱ)modle. At different temperatures the differentiations ofparasitic functional response were obvious,and the host number parasited by thewasps was maximum at 30 ℃.According to the results of analysizing therelationships between parasitic rate,temperature and host densities,the effect oftemprature on parasitic rate was less than on the host densities.
