中文摘要：调查温度在柑橘凤蝶Papillio xuthus L.滞育蛹解除中的作用。结果显示，羽化温度在15，20，25和30℃时，滞育蛹最早羽化分别在第45, 16, 11和第5天，发育历期分别为60.3，26.0，15.2和11.6 d，羽化持续时间分别为35，19，14和15 d。同时低温处理(10℃)显示，25℃时，低温处理0，20和40 d后，滞育蛹分别在处理后第38，第14和第13天开始羽化，羽化时间持续分别为40，71和16 d，发育历期分别为60.9，28.5和19.0 d。结果表明，随着羽化温度升高和低温处理时间延长，滞育蛹羽化时间提前，发育历期缩短。但当羽化温度超过25℃后，滞育蛹发育历期差异已不显著。
英文摘要：The role of temperature in the termination of pupal diapause in Papillio xuthus L. was investigated. The results showed that the first eclosion of adult from diapaused pupae was at the 45th, 16th, 11th and 5th day, respectively, at 15, 20, 25 and 30℃. Developmental duration of diapaused pupae was 60.3, 26.0, 15.2 and 11.6 days, respectively, at different temperature. The period of eclosion continued 35, 19, 14 and 15 days, respectively. Reared at 25℃ and treated with low temperature (10℃) for 0, 20 or 40 days, the first eclosion of adult from diapaused pupae was 38th, 14th and 13th days, respectively. The period of eclosion continued 40, 71 and 16 days, respectively. Developmental duration of diapaused pupae was 60.9, 28.5 and 19.0 days respectively. It indicated that with the increasing of rearing temperature and treating period with low temperature, the time of eclosion of diapaused pupae advanced, and developmental duration was shortened. When the temperature was beyond 25℃, the difference of developmental duration of diapause pupae was not significantly.
