我们研究了两个方面的社会控制的巢气候熊蜂群体：巢气候参数熊蜂积极下调，通过扇风和动态的殖民地响应作为殖民地规模的增加。熊蜂的殖民地暴露于二氧化碳，温度或相对湿度的增加。我们进行了70次温度试验（6个菌落），58次CO2试验（4个菌落）和4次湿度试验（2个菌落）。CO2浓度和温度的增加引起了扇响应，而相对湿度的增加没有。这是第一次报道在熊蜂群体中扇风以控制呼吸气体。随着刺激强度的增加，蜜蜂的数量增加。殖民地对3.2% CO2浓度的反应与殖民地对30°C温度的反应相当。一个显着的扇响应发生在1.6%CO2，浓度从未超过在一个大的领域巢在试点测量10天。我们调查了在广泛的殖民地规模（10至119名工人）的殖民地的反应。在巢通风的殖民地投资的总劳动力的比例没有显着变化，因此，随着殖民地的大小增加的扇工人的数量。此外，随着群体规模的增加，殖民地的动态反应也发生了变化：当群体规模较大（60个或更多个体）时，它们对环境扰动的反应要比个体较小时快。版权所有2002年动物行为研究协会。由爱思唯尔科技有限公司出版。保留所有权利。
We examined two aspects of the social control of nest climate in bumblebee colonies: which parameters of nest climate bumblebees actively down-regulate by fanning and the dynamics of the colony response as colony size increased. Colonies of Bombus terrestris were exposed to an increase in carbon dioxide, temperature or relative humidity. We performed 70 temperature trials (six colonies), 58 CO2 trials (four colonies) and four humidity trials (two colonies). An increase in CO2 concentration and temperature elicited a fanning response whereas an increase in relative humidity did not. This is the first report of fanning in bumblebee colonies to control respiratory gases. The number of fanning bees increased with stimulus intensity. The colony response to a CO2 concentration of 3.2% was comparable to the colony response to a temperature of 30°C. A marked fanning response occurred at 1.6% CO2, a concentration never exceeded in a large field nest during a pilot measurement of 10 days. We investigated the colony response over a wide range of colony sizes (between 10 and 119 workers). The proportion of the total workforce invested by colonies in nest ventilation did not change significantly; thus, the number of fanning workers increased with colony size. Furthermore, as colony size increased, the dynamics of the colony response changed: colonies responded faster to perturbations of their environment when they were large (60 or more individuals) than when they were small.
