摘要
在室温条件下测定了斜纹猫蛛亚成蛛及成蛛对茶尺蠖1～2龄幼虫的日捕食量及功能反应、捕食者自身密度效应和温度对功能反应的影响。斜纹猫蛛亚成蛛及成蛛对茶尺蠖幼虫的功能反应均呈Holling Ⅱ型反应,模拟模型分别为Na=0.9195Nt/(1+0.004703Nt)和Na=0.92268Nt/(1+0.005081Nt),自身密度反应模型分别为E=0.5419P^(-0.6052)和E=0.5139P^(-0.5812)。经X^2检验,以上模型模拟效果较好。
In this paper .value of prey eaten per day and functional response of O. sertatus to E. obliqua hypulina were studied. Adult and subadult of O. sertatus were both considered. Results of functional response can be simulated by Rolling equation (1959). Parameters were given in this paper. Influences of density of predators and temperature on the response have been determined respectively. The mutual interference among predators can be described well by Hassel and Varley's equation. The model considering the temperature influence has also been constructed.
