Thermoregulation of the Thorax is Critical for Bees and Other Endothermic Insects to Achieve High Rates of Flight Muscle Power Production. However, the Mechanisms Allowing Insects to Regulate Thorax Temperatures during Flight Are Not Well Understood. to Test Whether Variations in Metabolic Heat Production, Evaporation or Heat Transfer from the Thorax to the Abdomen Contribute to the Maintenance of Stable Body Temperatures during Flight in the Bee Centris Pallida, We Measured CO2 Production, Water Vapor Loss, Wingbeat Frequency and Body Segment Temperatures during Flight at Varying Air Temperatures (T(A)). While Hovering in the Field and While Flying in the Respirometer, …

SYNOPSIS. Thermoregulation of Elevated Thorax Temperatures is Necessary for Bees to Achieve the High Rates of Power Production Required for Flight and is a Key Factor Allowing Them to Occupy Widely Varying Thermal Environments. However, the Mechanisms by Which Bees Thermoregulate during Flight Are Poorly Understood. Thermoregulation is Accomplished by Balancing Heat Gain and Heat Loss Via the Following Routes: Convection, Evaporation, and Metabolic Heat Production. There Appears to Be a Diversity of Thermoregulatory Mechanisms Employed during Flight among Bee Species. Some Species, Particularly Bambus Spp., Actively Increase the Distribution of Thoracic Heat to the Abdomen during Flight as Air …
