白杨透翅蛾(Paranthrene tabanifor-mis Rott.)是我国东北、华北、西北和内蒙等地区杨树人工林的危险性蛀干害虫。幼虫为害树干和顶芽,形成秃梢和瘤状虫瘿,易被风折断。尤以苗木受害损失较大,并可随苗木传播到新区。该虫对杨树丰产林、防护林及城乡绿化造林威胁极大。长期采用化学农药防治,不仅成本高难度大,且易对环境造成污染和杀伤天敌。1984—1986年在黑龙江省杨树防护林地区,采用白杨透翅蛾性诱剂防治150万亩次,平均诱捕率达73％以上,防治效果达65—89％。防治成本比化学 Paranthrene tabanifor-mis Rott. Is a dangerous borer pest of poplar plantations in Northeast China, North China, Northwest China and Inner Mongolia. Larvae damage to the trunk and the top buds, the formation of bald and nodular goblet, easily broken by the wind. Especially in the loss of seedlings damage larger, and can be spread with the seedlings to the new area. The insects of poplar forest, shelterbelt and urban and rural afforestation afforestation threat. Long-term use of chemical pesticide control, not only costly and difficult, and easy to cause environmental pollution and natural enemies. 1984-1986 in Heilongjiang Province poplar shelterbelt area, the use of Poplar moths attractant control 1.5 million mu times, the average trapping rate of 73% or more, the control effect of 65-89%. Prevention costs more than chemistry
