*Post hoc comparison of the trapping methods. Methods bearing the same letter do not differ significantly at 5% level. Note that for An. coustani indoors, pairwise comparisons with aspiration could not be done as there were no females of this species collected by aspiration
All variables with the same letter implies that the trapping methods do not differ significantly at 5% level based on mean daily trap catch for each mosquito species. If two variables have different letters, they are significantly different at 5% level
