Toxorhynchites
Toxorhynchites, also called elephant mosquito or mosquito eater, is a genus of diurnal and often relatively colorful mosquitoes, found worldwide between about 35° north and 35° south. It includes the largest known species of mosquito, at up to in length and in wingspan. It is among the many kinds of mosquito that do not consume blood. The adults subsist on carbohydrate-rich materials, such as honeydew, or saps and juices from damaged plants, refuse, fruit, and nectar.
Aedes albopictus
Sporozoans of the genus "Ascogregarina" (Lecudinidae) infect the larval stage of mosquitoes. The species "Ascogregarina taiwanensis" was found in Asian tiger mosquitoes. When the adult mosquitoes emerge from their pupal case, they leave the infectious intermediary stage of parasites in the water and close off the infection cycle. Infected adults are generally smaller than non-infected adults and have an insignificantly higher mortality rate; therefore, food supply and larval density apparently play a role. In competitive situations, an infection with sporozoans can also reduce the biological fitness of other uninfected mosquitoes. However, the use of the parasites as an effective biological remedy to control mosquito populations is implausible because the host must reach the adult stage for the transmission of the parasites.
