Abstract
At the Jos Plateau in Nigeria 11 species of tabanid flies belonging to 6 genera were recorded by collecting adults and larvae. Haematopota pallidipennis and Chrysops distinctipennis were dominant at the early stage of the dry season. C. distinctipennis was regarded as a candidate vector of loiasis in the area. Three patterns of daily biting activity were seen in tabanid flies in the rain forest; crepuscular activity in Ha. guineensis, midday activity in Tabanus conformis and T. secedens, and daytime actively in T. besti. Parous rate of the flies was extremely high in C. distinctipennis, Ha. guineensis and Ha. pallidipennis. This result suggests a possibility of autogeny.
