This laboratory study found that wMel Wolbachia infection in Aedes aegypti mosquitoes alters several female post-mating responses, including reducing fecundity and fertility, increasing virgin female lifespan, and decreasing the ability of infected males to prevent female re-mating.
Researchers compared infected and uninfected mosquitoes, assessing outcomes like fecundity, fertility, longevity, and re-mating incidence. Key results showed that wMel infection significantly decreased female fecundity and fertility, regardless of mate infection status. Additionally, Wolbachia-infected males were less successful at inhibiting re-mating by their female mates. The findings suggest Wolbachia infection modifies female reproductive physiology and behavior, which could have implications for the efficiency of vector control programs using Wolbachia for population suppression or replacement.
