摘要
拟水狼蛛三种不同生理状态捕食白背飞虱成、若虫的六个组合功能反应不尽相同。除负囊成蛛捕食白背飞虱若虫接近HollingⅢ型反应外,其它组合均符合HollingⅡ型反应。在猎物密度5～25头范围内,守简易地用直线方法模拟。而对HollingⅡ型圆盘方程的拟合,用LRⅠ法比LRⅡ法为优。
Six functional response models Of wolf-spider pirata subpiratitus Boes. et Str. under three different physiological states in catching adult or larval white-back planthopper Sogatella furcifera (Horvath) were found various to some extent. All models, except that for the egg-bag carrying adult spiders, which was close to the Holling Ⅲ in catching larval white-back planthopper, agreed with the Hoiling Ⅱ. The functional response models can be simply simulated as a stright line when the prey density was 5-25 heads. Simulating Holling′s disc equation with LR I is better than with LR Ⅱ method.
