摘  要：
华北落叶松鞘蛾Coleophora sinensis Yang是我国华北地区落叶松Larix gmelinii var.principis-rupprechtii人工林的重要食叶害虫。应用性引诱剂诱捕器监测华北落叶松鞘蛾成虫发生期,并进行大量诱杀防治。结果表明:2011—2012年,在太岳山国有林管理局好地方林场和黑茶山国有林管理局石桥林场,华北落叶松鞘蛾成虫在高海拔地区比低海拔地区的始见期推后3~7 d,盛期推后2~4 d,末期一致,表现出随海拔升高而发生期集中的趋势。应用性引诱剂诱捕器大量诱捕后,华北落叶松鞘蛾幼虫虫口密度极显著降低,平均虫口减退率为60.07%;翌年平均诱蛾量极显著下降。

摘  要：
Coleophora sinensis Yang is a serious defoliating pest in Larix gmelinii var. principis-rupprechtii plantation of North China. Traps baited with sex-attractant of C. sinensis were set up to monitor the occurrence period of adults,and mass traps were conducted to analyze average reducing rate. The results showed that in 2011 and 2012,at Haodifang Forest Farm of Taiyueshan National Forest Administration and Shiqiao Forest Farms of Heichashan National Forest Administration,the initial occurrence period and peak stage of C. sinensis adults were 3 to 7 days and 2 to 4 days later relatively in high altitude area than that in lowaltitude area. The end stages were the same,and there was a tendency of concentration on emergence period with the rise of elevation. After mass trapping control with sex-attractant traps,the larvae density of C. sinensis on the infested trees was significantly reduced,with reducing rate of60. 07%,and the average trapping amount of C. sinensis decreased significantly next year.
