a About 10 houses were sprayed in each of the three study sites of the altitudinal transect during every survey, assigning our protocol to the Minimum Sample Size Approach (MSSA) [42]. However, houses were not randomly sampled, but biased by the tendency of targeting and spraying repeatedly those houses where previous enquiries were positive. Results obtained for average mosquito densities were therefore overestimated.
-
b ADH: Average female Anopheles density /house ± standard deviation.
-
c No: Number of female Anopheles mosquitoes.
