在加热过程中，同时测量了蜜蜂个体工蜂和雄蜂的瞬时耗氧量、肌肉电位频率、胸部温度和环境温度。 研究了这些参数之间的关系以及胸部温度对功率输入和温升的影响。 只有当飞行肌肉变得活跃时，氧气消耗才高于基础水平。 肌电位频率的增加与耗氧量的增加和胸温的升高相关。 胸温与环境温差与耗氧量呈线性相关。 每肌肉潜能耗氧量（μ l O2 . g（胸部）-1。MP-1）在无人机中的含量是工人的两倍。 然而，用于加热胸腔的耗氧量（μ-l O2 . g（thorax）-1（T（th）-T（a））。degrees-C-1）在工人和无人机中几乎相同。 胸部温度影响每肌肉电位消耗的氧气量（R10 = 1.5）。 无人机（R10 = 6-10）比工人（R10 = 3.6）对每100 MP的温度升高更敏感。 工人的耗氧量Q10值为3，无人机为4.5-6。 肌肉电位频率下降，工人的Q10 = 1.8，无人机为2.7。 工人和无人机的加热行为是不同的。 无人机产生的热量比工人少，并表现出更大的个体间差异的偏好热。 然而，观察到的环境温度和胸部温度之间的最大差异是无人机的22摄氏度和工人的14摄氏度，这表明无人机的潜力更大。
Instantaneous oxygen consumption, muscle potential frequency, thoracic and ambient temperature were simultaneously measured during heating in individual workers and drones of honey bees. Relationships between these parameters and effects of thoracic temperature on power input and temperature elevation were studied. Oxygen consumption increased above basal levels only when flight muscles became active. Increasing muscle potential frequencies correlated with elevated oxygen consumption and raised thoracic temperature. The difference between thoracic and ambient temperature and oxygen consumption were linearly related. Oxygen consumption per muscle potential (mu-l O2 . g(thorax)-1 . MP-1) was two-fold higher in drones than in workers. However, oxygen consumption for heating the thorax (mu-l O2 . g(thorax)-1 (T(th)-T(a)) . degrees-C-1) was nearly the same in workers and drones. Thoracic temperature affected the amount of oxygen consumed per muscle potential (R10 = 1.5). Achieved temperature elevation per 100 MP was more temperature sensitive in drones (R10 = 6-10) than in workers (R10 = 3.6). Q10 values for oxygen consumption were 3 in workers and 4.5-6 in drones. Muscle potential frequency decreased with a Q10 = 1.8 in workers and 2.7 in drones. Heating behaviour of workers and drones was different. Drones generated heat less continuously than workers, and showed greater interindividual variability in predilection to heat. However, the maximal difference between ambient and thoracic temperature observed was 22-degrees-C in drones and 14-degrees-C in workers, indicating greater potential for drones.
