| 摘 要： | 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 .

| Abstract: | The results of investigation and analyses showed that the amount of population of O. urama reached the highest level from June to August in Nanping, Fujian; except April, it kept over a high level including winter, and the predatory mites had obvious following efficiency in a year. The results of analyses by means of the Gray Theory indicated that the effect sequence of the ecological factor on eggs was temperature> predatory mites>humidity>rainfall, so was the population, and on larva and nymphs or adults, the sequences were all temparature>humidity> predatory mites>rainfall. |
