*
P values are calculated by Wilcoxon signed-rank test comparing nightly catch numbers for each method.
†
P values for proportion An. gambiae s.s. calculated by two-tailed Fisher's exact. “−” = not applicable as it is the reference method.
‡
Mean IST catch values from Liberia were reduced by 0.25× to compare with the 45-minute HLC sampling duration for each hour of the testing.
IST = Infoscitex tent; LTC = light trap catches; HLC = human landing catches.
