| 摘 要： | 本文报道了楸螟Omphisa plagialis Wileman的羽化昼夜规律和（25±1）℃、光周期L∶D=14∶10条件下的雌蛾求偶节律,用Y形管法测定了雄蛾对雌蛾性信息素粗提物的行为反应。结果表明：楸螟的羽化发生在10：00到23：00之间;雌蛾在羽化当天即开始求偶,求偶行为集中在暗周期的23：30到01：30之间。采用正己烷提取的雌蛾性信息素粗提物存在性信息素成分,对雄蛾具有一定的引诱活性。

| Abstract: | The circadian eclosion and the circadian rhythms of female calling behavior of adult Omphisa plagialis Wileman were observed at（25±1）℃ under 14L：10D.Behavioral responses of male moths to female sex pheromone gland extracts were studied in a Y-shaped tube.The results show that moths emerged from 10：00—23：00 and that female moths began to call on the day of eclosion and that calling peaked from 23：30 to 01：30.The hexane extract from female adult sex pheromone glands was comprised of sex pheromone components. |
