摘　　要：对皖西山区杉木害虫的多年调查资料和试验数据进行分类整理 ,统计分析气候条件、森林密度、地形条件、森林抚育、树龄、林木组成以及天敌等生态因子对双条杉天牛种群密度的影响。结果表明 ,双条杉天牛的危害程度和虫口密度与生态因子密切相关。Based on the data of surveying and experiment on the insect pest of Cunninghamia lanceolata Hook in the West Mountain areas of Anhui province,the relations between the population density of Semanotus bifasciatus Matsch of Cunninghamina lanceolata Hook and ecological factors such as climatic contrasts forest density,orographical conditions,forest tending thining,tree age,forest composition and native predator were analysed and studied,the results showed that the harm level and population density of Semanotus bifasciatus were related well to their ecological conditions.
