摘　　要：采用随机踏查法、性信息素诱捕法和解析受害枝条的方法,在石家庄城区及周边地区调查了国槐小卷蛾的危害树种状况和国槐小卷蛾种群数量的时间、空间消长动态。结果表明:国槐小卷蛾的寄主植物有8种。成虫1a有2次发生高峰,盛发期为5月下旬至6月中旬和8月下旬至9月中旬。第1代幼虫对寄主各部位的危害:复叶>嫩梢>花穗。第2代幼虫对各部位的危害:复叶>荚果>嫩梢。幼虫对寄主树冠不同方位和层次的危害表现为:东、南面重于西、北面,树冠上层重于树冠下层。The random reconnaissant survey,sex pheromone mass trapping trial and harmed branches anatomy method were conducted to investigate the plant species damaged by Cydia trasias,the temporal dynamic and spatial dynamic of C.trasias population.Results showed that there were eight species of host plants.Adult peak emerged from the end May to middle June and the end August to middle September in one year.The harmed degree of crown different parts caused by the 1st generation larva following the order of petiole>young shoot>flower cluster.However,which caused by the 2nd generation larva following the order of petiole>infruit>young shoot.Viewing from the four directions,the maximum of harmed leaves rate was in the East and South.The harmed leaves rate in the upper part of tree crown was more than that in the lower part.
