Fig 2. Mosquitoes effectively disseminated insecticide particles at the neighborhood scale.

The contour plots are a spatial representation of the (period-specific) probability that at least one sentinel breeding site in a surveillance dwelling had evidence of contamination with mosquito-disseminated pyriproxyfen, as predicted by the generalized linear model in Table 2: A, before; B, during; C, early after; and D, late after the trial. The intervention sub-area is outlined in white in panels B (with pyriproxyfen dissemination stations represented by blue dots) to D. The scale in panel D shows the color code of probabilities. Surveillance dwellings are represented by squares; note that surveillance was discontinued in the northernmost dwelling.
