Mosquito infection rates (all larval stages) in 10 sentinel villages: baseline and by year (n = 44,668).

Dissections from bimonthly intradomiciliary pyrethrum knockdown collections of mosquitoes showing percent infected with any larval stage (L1–3) determined by dissection. Results reflect only Anopheles sp mosquito dissections. Collections were generally performed in the same household compounds. Baseline data point is explained in Figure 6 legend. The total n value in the table is also reflected in the related graph (Figure 6). NA = not applicable, not available, or fewer than 100 mosquitoes dissected.°Started treatment in 2000.*Started treatment in 2001.**Started treatment in 2002.***Started treatment in 2003.
