| 摘 要： | 梭毒隐翅虫Paederus fuscipes Curtis是一种重要的天敌昆虫．本文就它对萝卜蚜Lipaphis erysimi Kaltenback)的捕食反应及其相互之间的干扰作了初步研究，捕食反应用Holling圆盘方程LRⅡ拟合，得出理论方程为Na=1．7575N／(1 0．1161N)，最大捕食量为15．1286头，当隐翅虫虫口密度增大时，它对萝卜蚜的捕食能力下降，相互之间有一定的干扰，用Hasell方程拟合，理论方程为a’=25．2872P^-0.4901。

| Abstract: | Paederus fuscipes Curtis is an important natural enemy of Lipaphis erysimi (Kaltenbach). This article has made a study about its predation and interference with each other.The Authors have used Holling's (1959) disc equation to analyze Paederus fuscipes Curtis predation to Lipaphis erysirni (Kaltenbach). Its functional model is that: Na=1.7575N/(1+0.1162N). The most consuming rate by Paederus fuscipes Curtis to Lipaphis erysirni (Kaltenbach) per day is 15.1286. When Paederus fuscipes Curtis density grows up, its predation to Lipaphis erysimi (Kaltenbach) is going to decline. They influence each other. Its equation is that: a'=25.2872 ~(0.4901) |
