材料一 雌蚕蛾能释放一种性引诱剂，可以把3km以外的雄蚕蛾吸引过来．虽然每只雌蛾所释放的引诱剂的数量不到0.01mg，但雄蛾却仍对其作出反应．有趣的是雄蛾对密封在玻璃瓶中的雌蛾虽然看得见，但却无动于衷．

材料二 卡尔逊（Karison）和林茨（Liischer）于1959年倡议采用性外激素（Pheromone）这一术语．它是昆虫分泌到体外的一种挥发性的物质，是对同种昆虫的其他个体发出的化学信号而影响它们的行为，故称为信息素，目前已人工合成20多种性外激素，用于防治害虫，效果显著，如利用性外引诱剂“迷向法”防治害虫．具体做法是，在田间释放过量的人工合成性引诱剂，使雄虫无法辨认雌虫的方位，或者使它的气味感受器变得不适应或疲劳，不再对雌虫有反应，从而干扰害虫的正常交尾活动．
