摘　　要：在(27±1)℃、光周期L12∶D12的条件下,测定了酪蝇卵巢对雄虫的引诱效果。结果显示:时段13:00-15:00和19:00-21:00的1日龄雌虫卵巢对雄虫的引诱效果最强。生测结果表明:卵巢(19:00-21:00)的丙酮提取物对雄虫的引诱活性显著强于二氯甲烷提取物;卵巢的正己烷提取物、水提取物对雄虫无显著引诱活性。雄虫对卵巢丙酮粗提物的反应高峰出现在9:00-13:00。The attraction of ovaries ofP. casei and the extract to males was tested under laboratory conditions [（27±1） ℃, L12 ： D12]. The results indicated that males were more attracted to the varies dissected at 13：00-15：00 and 19：00-21：00 than to that at the other periods. It was demonstrated that acetone-extract of ovary was more attractive to males than dichloromethane-extract. N-hexane-extract and water-extract of ovary didn＇t show significant attraction to males. Responding peak of males to acetone-extract appeared at 9：00-13：00.
