2. From the Culicidae family, mosquitoes that are a cosmopolitan family of small dipteran insects (flies) of primary medical and veterinary importance which comprise about 3 000 species.
Adults have piercing proboscis [noses] for feeding on nectar (males) or blood (females). Their larvae are aquatic, living suspended beneath the surface film of various water places. Some species transmit pathogens causing malaria, yellow fever, filariasis (caused by filarial worms), and dengue (an infectious tropical disease that is characterized by severe pains in the joints and back, with fever, and rash).

The word vector is a reference to a carrier, usually an insect or other arthropod, that transmits the causative organisms of disease from infected to noninfected individuals; especially, one in which the organism goes through one or more stages in its life cycle.
Mosquito populations can increase rapidly, and, depending on flooding and general weather conditions, mosquito control agencies cannot always keep up with mosquito problems in all areas. Very often, residents can help significantly by controlling mosquitoes around their homes and properties.
If people don't take on the responsibility of decreasing the mosquito population in their personal areas, the results can be very irritating (at a minimum) to deadly (the ultimate).
