Abstract
This study is based on collections from light traps at more than 30 widely distributed stations in southern Louisiana. Most of the traps were operated throughout the year by the Louisiana Mosquito Control Association. Of the 22 Culicoides species identified, 15 constitute new records for the State. The seasonal incidence is given for each species, and particularly for C. hollensis (Melander and Brues), which is the most prevalent Culicoides in this area.
