Thermoregulation of the Thorax Allows Honeybees (Apis Mellifera) to Maintain the Flight Muscle Temperatures Necessary to Meet the Power Requirements for Flight and to Remain Active Outside the Hive Across a Wide Range of Air Temperatures (T(A)). to Determine the Heat-Exchange Pathways through Which Flying Honeybees Achieve Thermal Stability, We Measured Body Temperatures and Rates of Carbon Dioxide Production and Water Vapor Loss between T(A) Values of 21 and 45°C for Honeybees Flying in a Respirometry Chamber. Body Temperatures Were Not Significantly Affected by Continuous Flight Duration in the Respirometer, indicating that Flying Bees Were at Thermal Equilibrium. Thorax Temperatures …
Mechanisms Of Thermal Balance In Flying Centris Pallida (Hymenoptera: Anthophoridae), Stephen P. Roberts, Jon F. Harrison, Neil F. Hadley

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, …
