1.在赤道10°以内采集的肉蝇的蛹滞育可能由低温而不是光周期诱导。滞育的阈值似乎在每个地理区域的生态相关温度的边缘附近。滞育期低温比低温滞育发生率高，滞育时间长，且与暗点相吻合.滞育在恒定的低温下持续数月，但在25° C下4天就足以打破斑腹蛙的滞育。四天的暴露量既可以分配为一个时间段，也可以分配为一个月内的四个一天单位，这表明蝇蛹具有精确的温度求和机制。幼虫食物中的含水量对蛹滞育发生率影响较小：加水10%使反应提高10%，减水10%使反应降低18%。5.雄虫和雌虫进入滞育的比例大致相等。什...
1. Pupal diapause in flesh flies collected within 10° of the equator may be induced by low temperature but not by photoperiod. The threshold for diapause appears to be near the fringe of ecologically relevant temperatures in each geographic area.2. Cool temperature during the photophase elicits both a higher incidence of diapause and longer diapause than cool temperature coinciding with the scotophase.3. Diapause persists for several months at a constant cool temperature, but four days at 25° C is sufficient to break diapause in P. spilogaster. The four-day exposure can be allocated either as a single block of time or as four one-day units spread over one month, suggesting that the fly pupa has an accurate mechanism for temperature summation.4. Water content of the larval food exerts a minor effect on pupal diapause incidence: 10% addition of water elevated the response by 10%, and 10% decrease of water reduced the response by 18%.5. Males and females enter diapause in approximately equal proportion.6. Wh...
