摘要
在实验室条件下 ,研究了草皮逍遥蛛 Philodromuscespitum对苹果黄蚜 Aphispomi的捕食功能 ,分析了在不同猎物密度、捕食者自身密度、猎物密度及自身密度的联合反应、相互干扰以及不同温度条件对捕食功能的影响 ;用 Holling、 Hassell方程模拟后的理论值与观察值比较接近 ,经卡方测验后 ,误差不显著( <P0 .0 5)。
Predatory functional response of Philodromus cespitum preying on Aphis pomi was studied under the condition of lab..It was also analyzed that density of predator and preyers, united reaction and interference and effects of preying function under different temperatures. Theoretical value simulated with Holling II,Hassell equations were closer with observational values, the differences was not obvious (< P 0 005 ) according to the test of χ 2 The results indicated that simulated equations could describe the predatory functional response of Philodromus cespitum .
