Seasonal activity of the loiasis vectors Chrysops dimidiata Wulp and Chrysops silacea Austen (Diptera: Tabanidae) was studied during 1987-89 in villages and surrounding forest of the Chaillu Mountains, Congo. Chrysops were captured mainly in the hot rainy season (November-May) and densities of both species were higher in the forest than in villages. C.

The principal catching site was a palm grove surrounded by forest 3 km from the village. Landing/biting densities of Chrysops were measured by standardized fly catches lasting 11 hr carried out twice a month.

It was based on the use of a new trap, not requiring insecticide impregnation, in which the captured Glossina are preserved. The results show that this simple, cheap trap is an effective method of control, resulting in a considerable decrease in the tsetse population and is easily operated by the villagers.
