Table 1
Time before (T0) or during control (T1 and T2), number of females (Nf), males (Nm), total number (Nt) of fuscipes fuscipes trapped in the Maro focus, southern Chad, and number of genotyped individuals (Ng). The sex-ratio (SR = Nm/Nf), with exact p-values for significant deviation from even SR (two-sided exact binomial test), densities of captured flies (Dc_X) (individuals per km2, X stands for GPS or GEPL), computed as Nt/S, and the trap-based effective population sizes and densities (De_traps-X = Ne_traps/SX) and its range (bracketed) are also given (see below for Ne computations).
