Geometridae), is an early-season defoliator that attacks a wide variety of hardwoods and, in some cases, conifers. The insect is native to Europe but has become established in at least three areas of North America including southeastern New England. The female-produced sex attractant pheromone of the winter moth was identified as (3Z,6Z,9Z)-1,3,6,9-nonadecatetraene (1), which also attracts a native congener
冬季蛾Operophtera brumata(鳞翅目:尺蛾科)是一种早期的落叶落叶者,攻击各种各样的硬木,有时还针叶树。这种昆虫原产于欧洲,但已在北美至少三个地区(包括新英格兰东南部)定居。冬天蛾的阴生产性引诱信息素被鉴定为(3 Ž,6 Ž,9 Ž)-1,3,6,9-nonadecatetraene(1),其也吸引了天然同源物,布鲁斯spanworm,Operophtera布鲁塞塔。需要解剖或(肯定)DNA分子测试来区分这两个物种的雄性。因此,对于冬蛾有选择性的诱捕方法将是期望的。信息素的几何异构体(3 E,6 Z,9 Z)-1,3,6,9-壬二烯(2)据报道可以抑制Bruce spanworm对陷阱的吸引而不会影响冬蛾的捕获,但是使用信息素和抑制剂的结合还没有被优化,抑制剂的合成也没有被优化。本文介绍了抑制剂的两个新的合成(3 é,6 Ž,9 Ž)-1,3,6,9-nonadecatetraene基于中间(3
