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。
Under the condition of (27 ± 1) ℃, photoperiod L12: D12, the inducing effect on the male was determined. The results showed that ovaries of 1-day-old female at the time of 13: 00-15: 00 and 19: 00-21: 00 had the strongest inducing effect on the male. The results of bioassay showed that the ovariectomy (19: 00-21: 00) acetone extract of male rats was significantly stronger than that of methylene chloride extract; n-hexane extract and water extract of ovary had no significant attraction to male active. The peak of the reaction of male to ovarian acetone crude extract appeared at 9: 00-13: 00.
