Table 1 Summary of tsetse fly catches and Trypanosoma parasite positivity rates identified by dissection

From: Tsetse distribution, trypanosome infection rates, and small-holder livestock producers’ capacity enhancement for sustainable tsetse and trypanosomiasis control in Busia, Kenya

  1. aApparent tsetse density FTD = ΣF/(T × D) where FTD means the average fly count per trap per day, ΣF is the total number of captured flies, T is the total number of functional traps used, and D is the number of days (48 h) for which the traps were functional
