Abstract
1. 1.Muscle potentials in fibrillar flight muscles of worker and drone honeybees were recorded extracellularly at thoracic temperatures from 30 to 10°C. 2. 2.Extinction temperatures for muscle potentials were higher in drones for all treatments. 3. 3.Cold acclimation (15°C) lowered extinction temperatures significantly in workers and drones. Acclimitization changed extinction temperatures significantly only in drones. 4. 4.Cold acclimitization had a bigger effect on the rate of muscle potential amplitude decline with decreasing temperature than acclimation. 5. 5.Acclimation and acclimitization had no effect on the increase of muscle potential duration with falling temperature. 6. 6.Muscle potential frequency during shivering was not much different between cold and warm treated bees.
