通过室内多异长足瓢虫对枸杞蚜捕食作用的研究表明,多异长足瓢虫成虫对枸杞蚜若蚜的捕食功能反应符合HollingⅡ型反应模型,拟合的圆盘方程为Na=0.571N/(1+0.0333N),其寻找效应随着枸杞蚜若蚜密度的增加而降低。多异长足瓢虫成虫对自身密度的功能反应用Watt模型拟合为A=75.21P-0.5339,其捕食作用率与个体间相互干扰作用的关系用Hassell-Varley干扰反应模型拟合为E=0.8636P-1.0515。
The study on the prey on the Lycium barbarum by indoor S. heterophylla showed that the predation functional response of A. solani to N. avenae conformed to the Holling Ⅱ reaction model and the fitted disc equation was Na = 0.571 N / ( 1 +0.0333N), its search effect decreases with the increase of the density of wolfberry aphids. The functional response of adult D. parabaci to its own density was fitted by Watt model to A = 75.21P-0.5339. The relationship between predation rate and inter-individual interference was fitted by Hassell-Varley interference model to E = 0.8636 P-1.0515.
