| 摘 要： | 研究了星豹蛛成蛛对棉蚜的捕食功能反应.结果表明:星豹蛛对棉蚜的捕食功能符合HollingⅡ模型,拟合方程为Na=1.033 8Nt/(1+1.033 8×0.009 4Nt);星豹蛛个体间相互干扰对捕食效应的影响可以用E=0.928 2P-0.256 1进行模拟;星豹蛛对自身密度的功能反应可以用A=65.53P-0.864 1进行模拟,且拟合结果均较为理想.

| Abstract: | The functional response of Pardosa astrigerain preying upon Aphis gossypii was studied.The results showed that the function response of adult Pardosa astrigera to Aphis gossypii was fit for Holling Ⅱ model,N_a=1.0338 N_t/(1+1.0338×0.0094 N_t).The relationship between predation efficiency and individual interference could be simulated by the Hassell and Varley model,E=0.9282 P~(-0.2561).The functional response of adult to the density of itself could be simulated by the watt model,A=(65.53)P~(-0.8641). |
