Many of the physiological traits in insects are shaped by environmental temperatures, which can influence their interactions with pathogens. Therefore, quantifying the thermal responses of the host-pathogen system is crucial for better understanding and predicting their dynamics due to environmental changes. This is particularly important in honey bees, which are experiencing severe colony losses around the world, notably due to infection with the Deformed wing virus (DWV). To investigate the influence of temperature on the honey bee/DWV relationship we exposed adult bees to low or high temperatures and determined the effects on viral titers and bee survival. Emerging bees naturally infected with DWV were reared in vitro at different temperatures ranging from 15 degrees C to 37 degrees C. In addition, some bees reared at 37 degrees C were exposed daily to acute heat treatments (40 and 43 degrees C). High temperatures significantly decreased DWV titers close to the initial viral load at emergence but increased bee mortality. The lowest temperature resulted in higher mortality, but virus load was not significantly impacted. In conclusion, our results indicate that temperature could contribute to seasonal variations in viral loads but do not suggest temperature to be used as a tool to eliminate viruses, even given that high temperatures limit viral multiplication.
