摘要研究了墨西哥尤卡坦半岛一种重要的无刺蜜蜂Melipona beecheii的体内温度波动。实验中使用了两个在树洞中筑巢的野生群体。鸟巢内的雏鸟和储藏罐使用远程温度计监测温度变化。用温度湿度计同时记录原木外的环境温度。非连续4天每小时记录一次体温，持续24小时。在白天和夜间观察到环境温度和巢内温度的差异。在所有情况下，育种区和储罐区的温度都与环境温度不同(P<；0.01)。在所有测量日期中，在白天(09.00h到20.00h)内温度与环境温度之间没有显著的关系(P>；0.01)。然而，在夜间环境温度较低时(21.00h至08.00h)，体内温度与环境温度显著相关(P<；0.01)。这些发现表明，白纹伊蚊自然巢内的温度在白天保持相对稳定，但在晚上往往会发生变化。夜间的菌落温度可能滞后于环境温度5-6小时。因此，在蜂巢中主动控制温度似乎不太可能，因此，确保巢内温度稳定的能力可能是限制该物种成功适应蜂巢培养的一个重要因素。
SUMMARY Intranidal temperature fluctuation was studied in colonies of Melipona beecheii, an economically important stingless bee from Yucatan, Mexico. Two feral colonies nesting in tree cavities were used in the experiments. The brood and storage pots inside the nests were monitored for temperature changes using a telethermometer. Ambient temperatures immediately outside the logs were recorded simultaneously with ther- mohygrometers. Temperatures were recorded every hour for 24 h on four non—consecutive days. Differences between ambient temperatures and temperatures within nests were noted during the day and night. In all cases temperatures in brood and storage pots area were different from the ambient temperature (P < 0.01). There was no significant relationship between intranidal and ambient temperatures during the day (09.00 h to 20.00 h) on all days of measurement (P > 0.01). However, during lower ambient temperatures at night (21.00 h to 08.00 h) intranidal and ambient temperatures were significantly correlated (P < 0.01). These findings indicate that temperatures inside natural nesting colonies of M. beecheii remain relatively stable during the day, but tend to vary at night. Colony temperatures at night may lag from 5–6 h behind ambient temperatures. Active temperature control in nests of M. beecheii thus seems unlikely, and therefore the ability to ensure stable temperatures within the nest might be an important factor limiting the successful adaptation of this species to hive culture.
