| 摘 要： | 在实验室条件下,研究了草间钻头蛛Hylyphantes graminicola对果蝇Drosophila melanogaster的捕食功能反应.结果表明,在一定范围内,草间钻头蛛捕食效应随猎物密度增加而增加;随自身密度增加而减小;随着蜘蛛和果蝇密度的增加,相互干扰明显,捕食效率下降;雌蛛比雄蛛捕食量大.

| Abstract: | In laboratory,this experiment study on functional response of Hylyphantes graminicola in preying on Drosophila melanogaster,as a result, the predation effect of Hylyphantes graminicola in preying on Drosophila melanogaster,which was slowly increasing as the density of prey increasesd on a scale , was slowly decreasing as the density of predator increased. When spiders and prey both increased,the disturbation is obvious. The efficiency of preying decreased. The predation amount of female is bigger than that of the male. |
