摘要
对松针红蜡蚧的生态特性和危害行为进行研究表明,此虫1年发生1代,其大发生受到土壤、地形、坡向和气候等多种因素的影响;它通过取食叶汁并分泌蜡状蜜露导致发生烟煤病,严重影响马尾松针叶的光合作用,使树木生长受阻而最终致死。松针红蜡蚧虫口密度与针叶变黑呈正相关,受害木的材积生长率受到较大影响。在发生区域内,松针红蜡蚧种群呈均匀分布,个体之间相斥。
The red wax scale(Ceroplastes rubens)occurs in most parts of southern China. There is one generation a year. The population distributes evenly with the individuals rejecting each other. The outbreak is affected by various factors such as the soil, landform, exposure and weather. Feeding on the sap of the needle, the pest exerets waxy honey dew to cause sooty mold which significantly affects the photosynthesis of the needle, retarding the growth and causing eventual death of the entire tree. The population density shows a positive correlation to the blackening degree of the needle. The volume growth of the damaged tree is affected more seriusly.
