葡萄虎天牛的雄性信息素是从雄虫整体抽提液和容器洗涤液中分离出来的,鉴定得出它是由(2S,3S)—辛二醇(1)和(2S)一羟基—3—辛酮(2)组成的混合物。在触角电位实验中,每种组成分表现出特殊的反应,雌虫被比例为80∶20至95∶5的(2S,3S)—辛二醇:(2S)—羟基—3—辛酮混合物所吸引。 The male pheromone of the grape tiger was isolated from the male extract and the container wash and identified as consisting of (2S, 3S) -octanediol (1) and (2S) monohydroxy- 3-octanone (2). In the tentorial potential experiment, each component showed a specific response with the female being mixed with (2S, 3S) -octanediol: (2S) -hydroxy-3-octanone mixture in a ratio of 80:20 to 95: 5 Attracted.
