【摘要】 研究八斑鞘蛛在多种猎物共存时的日捕食量,功能反应,捕食作用率。在有棉铃虫和棉蚜共存且密度互补时,八斑鞘蛛对棉铃虫的功能反应属Holling Ⅲ型反应;一种猎物密度变化,其他种猎物密度固定时,功能反应呈Holling Ⅱ型反应。研究了捕食作用率与猎物共存种类,相对丰盛度,捕食者本身数量的关系。 计算机(IBM-PC)模拟结果表明:捕食者个体间的相互干扰、温度、猎物内禀增长率对系统稳定性有一定影响。更多还原

【Abstract】 In this paper, value of prey eaten per day functional response and rate of predation were studied. The functional response of the spider to pest is Holling I type or Holling I type. Mutual interference affected the predation efficiency of the spider. The selective predation of the female adult spider to both cotton bollworm and cotton aphis was studied. This paper suggests a simulation model as follows :Simulations concluions is follows : mutual interference, bettween predators, temperature. intrinsic rate of nature increase influence on the stablity of the model.更多还原
