In North America, there are only two Culicoides spp. proven to transmit BTV and/or EHDV-Culicoides (Hoffmania) insignis Lutz (Diptera: Ceratopogonidae) and Culicoides (Monoculicoides) sonorensis Wirth and Jones (Diptera: Ceratopogonidae). Culicoides sonorensis is considered the primary vector due to its wide distribution across much of North America, whereas C. insignis has a neotropical distribution historically limited to peninsular Florida. However, Culicoides surveys conducted 2007 to 2015 have detected the presence of C. insignis in five southeastern states (Florida, Georgia, Alabama, Mississippi, and Louisiana), suggesting C. insignis has or is currently experiencing a northwestward range expansion in the southeastern United States. Because C. insignis has a neotropi...

A bait was sought that: (1) was attractive to the target species, (2) could be distributed by aircraft, (3) was as effective (or more so) than the currently used fish meal polymer bait, and (4) could be produced in large numbers by automated procedures and could be purchased by user groups at substantially lower cost. Ten field trials were conducted to document raccoons' bait flavor preferences, evaluate a new vaccine sachet bait coated with various attractants, and determine if the sachet bait would effectively deliver Raboral V-RG oral rabies vaccine (Merial Limited, Athens, Georgia, USA) to this species. Raccoons preferred fish and crustacean-based flavors over those derived from plant materials. Raccoon visits to tracking stations, frequency of bait removals, and percent of sachets discarded by this species that were emptied ...
