The genus and subgenus categories within Culicidae and placement of Ochlerotatus as a subgenus of Aedes.
Many species of Culicidae are of major medical, veterinary, and economic importance. To facilitate discussion among taxonomists, medical entomologists, ecologists, and vector control specialists, it is essential that culicidologists be able to readily recognize individual genera. Adult female mosquitoes, the stage most often encountered in surveys, should be identifiable to genus without dissec...
