    Palpalis group tsetse, of which the G. fuscipes subspecies are estimated to be responsible for about 90% of all HAT cases inhabit fairly conserved riparian environments [31, 33]. The flies of this group are able to adapt to and easily colonize peridomestic habitats [ 25 ], including suburban areas surrounding cities, for example, Kinshasa Dubinski, I. M. & Wohl, E.

    Sampling intensity for any particular method is denned as the catch of flies in different segments of the non-feeding phase of their current cycles, expressed as a percentage of the catch of flies that are just entering the feeding phase. Two examples are given, of Glossina palpalis in Nigeria and G. morsitans in Zambia. In both cases, sampling The results show that Cu, Zn, Pb and Cd in the sediments are seriously polluted. Viewed from the plane, the main pollution areas are the upstream, the two tributaries and the tributaries and main river crossings. Viewed from the vertical, the heavy metals pollution roughly decreases with increasing sediments
