Phase 1 and 2 summary outcomes

Pre-intervention catches of 2.7 (range: 0-114) tsetse/trap/day where 84% of riverine traps caught tsetse flies. Phase 1 intervention coverage 7km: mean catches reduced to =<1 tsetse/trap/day across. Phase 1 blocks causing reduction in tsetse density in 5km (not 7km due to reinvasion “edge effect”). Phase 2: coverage expanded to 21km: mean catches of <0.5 tsetse/trap/day across Phase 1 blocks causing >90% reduction in tsetse density with 19km
