Detailed explanation-1: -Mosquitoes of the genus Culex are generally considered the principal vectors of WNV, in particular Cx. Pipiens. WNV is maintained in mosquito populations through vertical transmission (adults to eggs). Birds are the reservoir hosts of WNV.
Detailed explanation-2: -Mosquito-borne diseases are those spread by the bite of an infected mosquito. Diseases that are spread to people by mosquitoes include Zika virus, West Nile virus, Chikungunya virus, dengue, and malaria.
Detailed explanation-3: -Culex mosquitoes are accepted as the primary global transmission vector; C. tarsalis is a main mosquito vector of WNV in the western United States and can feed on a variety of avian and mammalian species (95, 163).
Detailed explanation-4: -Mosquitoes are the major vectors for arthropod-borne viruses (arboviruses) of medical importance. Aedes aegypti and A. albopictus are the most prolific and widespread mosquito vectors being responsible for global transmission of dengue, Zika and Chikungunya viruses.
