摘　　要：以云南省江边林业局的冲头和鲁地林区为基地进行研究．对云南松脂瘿蚊（ＣｅｃｉｄｏｍｙｉａｙｕｎｎａｎｅｎｓｉｓＷｕｅｔＺｏｕ）进行了形态描述，对生物生态学特性作了系统研究；建立了该虫５个世代的自然种群生命表，确定了自然控制的关键因素并进行了分析和运用．Thirteen species of the genus Cecidomyia have been reported from North America and Eurasia.They are known as pine resin midges infesting mainly the pines and also spruce and fir.The species studied was first discovered in a Pinus yunnanensis plantation of Jiangbian Forestry Bureau,Mile County of Yunnan Province in 1973.The larvae feed on the resin of new twigs retarding the tree growth.The infestation has now extended to approximately 6000 hectares reaching an injury rate up to as high as 796%100% including killed trees in some seriously infested stands.The morphological characteristics of the pest are discribed.The biology and of this resin midge are closely studied to provide a reference for suggesting the management measures of the pest.The key factor analysis based on its 5generation lifetable data has been made to help formulate population trend prediction.
