调查分析结果表明 :竹小爪螨 (Oligonychusurama Ehara)种群数量在福建南平竹林内 6月上旬到 8月上旬达到最高水平 ,除 4月外 ,其余时间保持在较高水平之上 ,以成螨和卵滞育 ,滞育期间具有较高的螨口基数 ,捕食螨对该螨有明显的跟随效应 .应用灰色理论分析表明 :4种生态因子对竹小爪螨卵的影响大小顺序为气温 >捕食螨 >相对湿度 >降雨量 ;对幼、若螨和成螨的影响大小顺序均为气温 >相对湿度 >捕食螨 >降雨量 ;就种群系统而言 ,其影响顺序与卵相同 .
The results of investigation and analysis showed that the population of Oligonychusurama Ehara reached the highest level in early April and early August in Nanping, Fujian. Except for April, the population remained at a relatively high level for the rest of the year. Eggs diapause, diapause period has a high mite base number, predation mites on the mite had a significant follow-up effect.Application of gray theory analysis shows that: four kinds of ecological factors on the bamboo small mite egg size order of temperature> predation Mites> relative humidity> rainfall; the effects on young, nymphs and adults were all in the order of temperature> relative humidity> predation mites> rainfall; in the case of a population system, the order of influence is the same as for eggs.
