| 摘 要： | 在实验室条件下,研究了二斑叶螨(Tetranychus urticaeKoch)的3种主要天敌小十三星瓢虫(Adonia var-iegata)、草间小黑蛛(Erigonidium graminicolum)和中华草蛉(Chrysoperia sinica)的成、幼虫对二斑叶螨不同密度的控制作用.在一定的猎物密度范围内,捕食量随着猎物密度的增加而增加,分别用Holling的圆盘方程拟合,经卡方检验,其实测值和理论值均无显著差异.3种天敌各自在不同情况下对二斑叶螨的控制作用,表明其具有重要的保护利用价值.

| Abstract: | The predaceous role of Adonia variegata,Erigonidium graminicolum and Chrysoperia sinica,three major natural enemies of Tetranychus urticae Koch,was researched under different densities in laboratory.It was observed that the fed number per day would increase with the increase of density of mite within certain density range.The results were simulated with mathe matical model of Holling,and there were not obvious differences between the theoretical dates and the practical dates.The control role of the three natural enemies to the mite in different conditions showed significant value. |
