摘要：对光周期和温度对美凤蝶峨眉种群滞育诱导的影响进行了研究,结果表明:光周期对美凤蝶滞育的诱导作用与温度有关,在20℃的恒温条件下,光照在12～13 h范围内,随着光照时间的缩短,滞育个体增加,在光照时间短于12.5 h后达到100%;在25℃时,光照时间在11～13.5 h范围内,随光照时间的缩短,滞育率增加,但没有出现全部个体滞育的情况,最高滞育率为94.5%;在30℃时,在实验光周期范围内没有出现滞育个体。温度对滞育的影响受光周期的影响,在相同光照条件下,在一定温度范围内,随着温度的上升,滞育率下降,当温度上升幅度达到30℃,无论长短光照条件下均不出现滞育个体。只有在短光照条件下,低温才有利于滞育,而长光照和高温则有利于个体的发育而抑制滞育产生。短光照对滞育的诱导作用具有累积效应。在20℃恒温条件下,美凤蝶的临界光周期为LD 13 h 11 min∶10 h 49 min;而在25℃恒温条件下,美凤蝶的临界光周期为LD 12 h 49 min∶11 h 11 min。随着温度的升高,临界光照长度缩短。美凤蝶对光周期的敏感期为5龄幼虫。
The effects of photoperiod and temperature on diapause inducing of the great mormon butterfly Papilio memnon were studied, which came from the population of Emei areas, Sichuan Province. The effects of photoperiod on diapause were related to temperature. Under constant temperature 20 ℃, the percentage of diapause individuals went up with the shortening of daylength during 12 h to 13 h, and reached to 100% when daylength less than 12.5 h. Under constant temperature 25 ℃, the percentage of diapause individuals went up with the shortening of daylength during 11 h to 13.5 h, too, and arrived 94.5% when daylength at 12 h, but the percentage didnot arrive to 100%. Under constant temperature 30 ℃ ,no diapause happened. The effects of temperature on diapause were also related to photoperiod. Under the same daylength and in the range of test temperature, the percentage of diapause individuals went down with temperature increasing. When temperature arrived to 30 ℃, no individual went to diapause whether daylength short or long. Only short daylength and low temperature were benefit to diapause, long daylength and high temperature were benefit to growth. Short daylength had a cumulative effect for inducing diapause. Under constant temperature 20 ℃, the critical photoperiod of Papilio memnon was LD 13 h 11 min： 10 h 49 min, under constant temperature 25 ℃, the critical photoperiod was LD 12 h 49 min： 11 h 11 min. The critical daylength shortened with the rising of temperature. The fifth instar larvae of Papilio memnon is the sensitive stage to photoperiod.
