Laboratory experiments were undertaken to determine whether wMelPop infected Aedes aegypti mosquitoes were more susceptible to predation by six naturally occurring predator species (cyclopoid copepods‚ fish‚ predatory Toxorhynchites mosquito larvae and a salticid jumping spiders)‚ compared with uninfected Aedes aegypti mosquitoes. The trials indicated that wMelPop infected and uninfected Ae. aegypti larvae and adults were equally susceptible to predation to all six tested predators. In addition‚ there was no evidence of horizontal transfer of wMelPop from Ae. aegypti into naturally occurring predators.
