The effects of adrenergic compounds on the thermoregulation of resting honey bees were investigated using a non-traumatizing approach. Bees fed ad lib were treated orally and kept at an ambient temperature of 22 degrees C; the surface thoracic temperature was monitored by infrared thermography. Bees were treated with the adrenergic agonists epinephrine and ephedrine, and with the beta-blocking agent alprenolol. Low doses of adrenergic agonists had no significant effect on thermogenesis, but high doses caused a hypothermia. Alprenolol triggered a dose-dependent hypothermia that was reversed by low doses of epinephrine and ephedrine. Results are discussed with reference to the metabolic and neural adrenergic pathways that may be involved in bee thermoregulation.
采用非创伤性方法研究了肾上腺素能化合物对静息蜜蜂体温调节的影响。自由采食的蜜蜂经口服处理后,置于22摄氏度的环境温度下;通过红外热成像监测胸部表面温度。给蜜蜂分别使用肾上腺素能激动剂肾上腺素和麻黄碱以及β受体阻滞剂阿普洛尔进行处理。低剂量的肾上腺素能激动剂对产热没有显著影响,但高剂量会导致体温过低。阿普洛尔引发了剂量依赖性体温过低,低剂量的肾上腺素和麻黄碱可使其逆转。结合可能参与蜜蜂体温调节的代谢和神经肾上腺素能途径对结果进行了讨论。
