Studies on trap effectiveness of tsetse flies (Glossina spp. (Diptera: Glossinidae)) in the Tanga Region of north eastern Tanzania.
At Mkwaja and Mivumoni ranches in NE Tanzania the catches of Glossina pallidipes Austen, G. brevipalpis Newstead, G. morsitans morsitans Westwood and G. austeni Newstead were usually about two to three times greater in traps of the NGU, Epsilon and F3 types than in the Blue Biconical and Pyramidal traps when used with odours. Catches from moving men were improved about three times when the men carried a black screen, and increased by about another seven times for female G. pallidipes when a vehicle was the bait. The sensitivity of surveys for tsetse was estimated to be improved about 300 times for G. pallidipes and two to five times for G. brevipalpis and G. m. morsitans when surveys use traps instead of vehicles as baits. The needs for further research and field trials with survey methods are discussed.
