Effect of temperature on the biotic potential of honeybee microsporidia.
The biological cycle of Nosema spp. in honeybees depends on temperature. When expressed as total spore counts per day after infection, the biotic potentials of Nosema apis and N. ceranae at 33 degrees C were similar, but a higher proportion of immature stages of N. ceranae than of N. apis were seen. At 25 and 37 degrees C, the biotic potential of N. ceranae was higher than that of N. apis. The better adaptation of N. ceranae to complete its endogenous cycle at different temperatures clearly supports the observation of the different epidemiological patterns.
