Publication Date



The reproductive status and body size of four Tabanus species collected from canopy traps baited with carbon dioxide and from a Jersey bullock were compared. Parity rates, sperm prevalence, stage of follicular development in terminal follicles of parous females, prevalence of females retaining eggs, average number of eggs retained in parous flies, and the body size of parous females did not differ significantly between sampling methods. Based on the presence of nulliparous host-seeking flies, Tabanus pallidescens Philip and T. wilsoni Pechuman can be added to the list of tabanids found to be anautogenous.
