摘要
杨干透翅蛾（Sesia siningensis）在湟中县境内6月至9月为成虫扬飞期，我们在5个虫害试验区用内含顺3-顺13碳二烯醇的性信息750ug剂量杨干透翅蛾引诱剂1枚，放置在三角型诱捕器内，悬挂100个诱捕器于青杨（Poulus cathayana Rehd）树干 2．5～3.5m处进行大量诱杀试验，共诱集成虫1927头，试验区被害青杨与2002年相比虫口减退率为33．94％。
Sesia sinigensis eclosion stage are from June to September in Huangzhong county Qinghai province. The experiment for Control Sesia sinigensis on Populus cythayana was carried out using sex attractant in five target areas in 2006.The triangle-shaped trap containing 750ug of cis-3-cis-13-dienol was placed on trunk of Populus at height of 2.5 ～ 3.5m for trapping the adults.
