  1. Comparison of the minimum number of sampling devices required to estimate relative abundance of Ae. aegypti, at three precision levels (D), based on expected mean females collected per AGO-B per day (ma), or expected mean eggs collected per ovitrap pair per day (me). Expected numbers of specimens per trap per day for both devices were aligned using a fitted major axis regression [Log10 (me) = 1.250 + 1.306 Log (ma)].
