Enzyme linked immunosorbent assay (elisa) was employed to determine the rate of digestion of blood proteins ingested by teneral and non-teneral laboratory reared Glossina morsitans morsitans at different time intervals after feeding. This test showed that non-teneral flies digested the species distinguishing bloodmeal components faster than tenerals. At 48 hr post-feeding, the bloodmeal donor was identifiable in 87.5% of the teneral tsetse and 55.5% of non-teneral tsetse flies. Among 160 bloodmeals of G. m. submorsitans collected from the upper Didessa river valley 54.4% (87/160) were with identifiable hosts, of which warthog accounted for about 52.9 (46/87) of meals, whereas human and buffalo blood accounted for about 21.8% (19/87) and 12.6% (11/87) of the meals, respectively. Others like giraffe, goat, cattle and elephant accounted for few bloodmeals. Thus warthog appeared to be the major host for G. m. submorsitans in the study area.
