Summary

House flies exhibit behavioral fever, adjusting temperature to combat fungal infections. They modulate fever intensity and duration based on pathogen dose, balancing costs and benefits.

Area of Science:

  • Behavioral ecology
  • Insect pathology
  • Thermoregulation

Background:

  • Fever benefits infected hosts but incurs costs.
  • Endotherms manage fever costs physiologically.
  • Behavioral thermoregulation in constraining fever costs is less understood.

Purpose of the Study:

  • Investigate the behavioral fever response in house flies (Musca domestica L.).
  • Examine how different doses of the fungal entomopathogen Beauveria bassiana affect fever behavior.
  • Understand the modulation of fever costs and benefits in insects.

Main Methods:

  • Infected house flies with varying doses of Beauveria bassiana.
  • Monitored behavioral thermoregulation and temperature selection.
  • Correlated fever patterns with fungal growth.

Main Results:

  • Infected flies initiated behavioral fever by selecting hot temperatures early in the day.
  • Flies transitioned to cooler temperatures as the day progressed.
  • Higher fungal doses induced more intense fever responses, impacting fungal growth.

Conclusions:

  • Insects can modulate behavioral fever degree and duration based on pathogen challenge severity.
  • House flies balance the costs and benefits of fever through behavioral thermoregulation.
  • Behavioral fever is a key strategy for insects to manage infections.
