From: Leishmaniasis sand fly vector density reduction is less marked in destitute housing after insecticide thermal fogging

Figure 4

Housing destituteness and sand fly abundance. (A) Cumulative sand fly abundance before the fogging as a function of Housing Destituteness, HP (three traps nights) (B) Cumulative sand fly abundance for the nine traps nights that contained the two interventions as a function of HP. The solid black line is the fit from a negative binomial model with a breakpoint (C) Changes in domiciliary sand fly density per house and trap night as function of HP (D) Changes in peridomiciliary sand fly density per house and trap night as a function of HP. In panels (A) to (D) symbols indicate whether a house was intervened, triangles, or not, circles. In panels (C) and (D) black symbols represent the pre-intervention densities and green symbols post-intervention densities. To ease the tracking of changes in each house we joined the pre and post intervention densities with a line whose color is blue when sand fly density decreased and red when sand fly density increased. In panel (C), the solid black line represents Table 4 model fit.
