  草螟蛾（Euproctis taiwana (Shiraki) (Lepidoptera: Lymantriidae)）的性引诱信息素成分的鉴定。

  摘要：

  通过气相色谱-触角电子图检测、气相色谱-质谱联用分析、微反应和合成的组合，从雌性草螟(Euproctis taiwana (Shiraki)) 的腹尖中分离并鉴定出两种化合物。这些化合物是(Z)-16-甲基-9-十七烯基异丁酸酯(74.8％)和16-甲基十七烯基异丁酸酯(25.2％)。它们的总量被确定为大约。29.8 纳克/女性。现场生物测定表明，(Z)-16-methyl-9-heptadecenylisobutyrate 是雄性飞蛾的性引诱剂。这些化合物以前没有被发现作为 Euproctis 属中的性信息素成分。
