| 摘 要： | 本文观察了Aphytis sp.在25种密度组合下的寄生与摄食,表明Aphytis sp.的功能反应适合Ⅱ型曲线,摄食作用随寄生蜂密度的增加而加强,随寄主密度的增加而减弱。并建立了新的二元寄生模型,模拟效果较好。

| Abstract: | This paper dealt with the. effects of parasitism and host-feeding for Aphytis sp. in 25 combinations of density. It followed that the functional response of Aphytis sp. was fit for Holling- E curve. The host -feeding increased as the density of parasites increased, but decreased as the density of hosts increased. Furthermore, a new model for parasitism has been set up:Where a' : the lowest searching rate, m: the interference oscillation of searching rate, T'b : the shortest handling time, n: the interference oscillation of handling time. The fitting results of the model was better than that of the Holling- E model and others. |
