Supplementary Figure 8: Effect of BG-Sentinel fan speed on mosquito collection.

(a) BG-Sentinel fan speed values plotted as a function of remaining trap battery voltage. Measurements taken from 20 test BG traps once per day until the battery died. Scraps of paper were added to traps represented by grey dots in order to mimic the effect of captured mosquitoes and other insects and debris on air flow. Pearson’s r = 0.95 (one-sided correlation test: P = 2.2 x 10−16). (b) Number of female mosquitoes captured in a BG trap night at control sites plotted against the trap fan speed as measured immediately before mosquitoes were removed from the trap. Analysis limited to collections after June 01 and before October 01. Pearson’s r = 0.13 (one-sided correlation test: P = 6.7 x 10−5).
