Abstract: Warming temperatures allow mosquitoes to colonize additional habitats, potentially increasing the prevalence of disease. Wolbachia pipientis can mitigate the spread of pathogens, but its within-host dynamics under heat stress remain understudied. We examined the impacts of temperature on the microbiomes of adult Culex pipiens. The relative abundance of Wolbachia was higher in the 25°C treatment. There was no difference in fungal alpha diversity. There was a significant difference in bacterial and fungal community composition.
