Some species of mosquitoes spread dangerous human diseases. But mosquitoes have their own parasites, like the protozoan Ascogregarina barretti, which is related to the organisms that cause malaria and toxoplasmosis, and infects the native North American mosquito Aedes triseriatus. The invasive mosquito, Aedes japonicus, a recent arrival in North America, does not contract As. barretti. Will the presence of Ae. japonicus dilute the prevalence of the parasite in the native mosquito? Find out this August at Katie Westby’s talk during ESA’s 2016 Annual Meeting in Fort Lauderdale, Florida.
