Mosquitoes apart from causing nuisance to mankind play a major role in the transmission of more human diseases than any other arthropods.

Mosquitoes breed in various types of water habits ranging from clean water collections to organic polluted waters depending on the species.

Adult males feed on nectar from plants. Female mosquitoes require blood meal for egg production. Because female mosquitoes feed on blood, disease causing pathogens (eg malaria parasite) can be transmitted from person to person or in some cases (eg arboviruses) from animals to man via vector mosquitoes.
