For each month (i e, sampling period): number of captured mosquitoes (Mosq capt); human biting rate (HBR); proportion of parous females (Q); duration of the gonotrophic cycle (g) in days; survival rate (p); proportion of endophagous females (Endo); median hour of biting activity (Median hour), i e, hour at which 50% of mosquitoes have already bitten; number of mosquitoes processed by PCR to search for Plasmodium parasites (Mosq PCR); sporozoite rate (s) and its 95% confidence interval; estimates of the human feeding rate (a); estimates of the vectorial capacities CV; entomological inoculation rate (EIR); infective life time (in days), and density of infective females.
