Nasal Bots of White-Tailed Deer in the Southeastern United States

Nasal bots (Cephenemyw sp.) were found in 107 (4.4 percent) of 2,423 white-tailed deer (Odocoueus virginianus) examined from the following states: Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Maryland, Mississippi, North Carolina, South Carolina, Tennessee, Virginia, and West Virginia. Infected deer were not found in Alabama, Kentucky, and Tennessee. The parasite was most prevalent in the winter and summer. There were no significant differences in infestations between sexes or age groupings. The average infestation was 9 larvae per infested deer and only 5 deer harbored more than 30 larvae. Cephenemyia sp. did not appear to be a significant disease factor for white-tailed deer of the southeastern United States.
