摘要
根据美国白蛾完成1个世代所需要的有效积温，对青岛市区2006～2008年气温统计：有效积温分别为2258．3日度、2102．9日度和1982．2日度，则美国白蛾的发生代数分别为2．55代、2．38代、2．24代。青岛属于2～3代区。摸清了美国白蛾在青岛的发生规律，制定了年生活史表，为及时有效的防治美国白蛾提供理论基础。
Through to statistics effective accumulated temperature （EAT） of Hyphantria cunea Drury for 2006 - 2008, their EAT were 2 258.3,2 102. 9 and 1 982. 2 degree-day respectively. The yearly generations of Hyphantria cunea Drury occurrenced 2.55, 2. 38 and 2.24 generations in Qingdao where belongs to 2～3 generation of areas2 Find out the occurrence regularity of Hyphantria cunea Drury in Qingdao, establishmental a table of life history. Proyide a theoretical basis for timely effective prevention and treatment of Hyphantria cunea Drury.
