3种天敌对土耳其斯坦叶螨的捕食功能反应的初步研究

Preliminary Study on Predaceous Role of Three Natural Enemies to Tetranychus turkestani

在实验室条件下 ,对土耳其斯坦叶螨的主要天敌 :肩毛小花蝽 (Oriusniger)、中华草蛉 (Chrysoperlasinica)、深点食螨瓢 (Stethoruspunctillum)进行了饲养 ,观察分析了 3种天敌对不同密度、不同螨态的捕食功能反应 ,在一定猎物密度范围内其捕食量随着猎物密度的增加而增加。又据实验结果 ,分别用Holling圆盘方程模拟 ,经卡方测验 。

In laboratory,the predaceous role of three natural enemies to Tetranychus turkestani was studied in different density,three natural enemies are Orius niger,Chrysoperla sinica and Stethorus punctillum.The number of feeded per day was increased as the density of mite in certainly density range of mite.The results was simulated with mathematical model of Holling and there are not obviously different between the theoretical dates and the practical dates.
