Abstract

The host-seeking behavior of hematophagous arthropods can be altered by symbiotes, thereby biasing sampling techniques and inaccurately reflecting symbiote or vector prevalence. Knowledge of any altered vector behavior is essential in vector control and monitoring. Species of Chrysops are vectors of human and animal pathogens. Six species of Chrysops were collected at two locations in South Carolina to determine if diurnal host-seeking behavior was influenced by trypanosomatid infection. Fifty-five percent of the host-seeking Chrysops were infected with trypanosomatid parasites. Prevalence of infection in host-seeking Chrysops were statistically indistinguishable during both the morning and evening at both sites. The results indicate that the prevalence of parasites among wild host-seeking Chrysops might not be influenced by infection status.
