Epistasis underlying a fitness trait within a natural population of the pitcher-plant mosquito, Wyeomyia smithii.
We selected on divergent photoperiodic response in three separate lines from a natural population of the pitcher-plant mosquito, Wyeomyia smithii. Line crosses reveal that there exists within a population, diverse epistatic variation for a fitness trait that could contribute to adaptive potential following founder events or rapid climate change.
