From: Reduced exposure to malaria vectors following indoor residual spraying of pirimiphos-methyl in a high-burden district of rural Mozambique with high ownership of long-lasting insecticidal nets: entomological surveillance results from a cluster-randomized trial

Fig. 4

Monthly trends in the average number of mosquitoes collected per trap-night in indoor human-baited CDC LTs during the cluster-randomized trial for a An. funestus s.l. and b An. gambiae s.l. Geometric means are presented. In a, * indicates mosquito collection IRRs that are significantly different from 1 (zero-inflated negative binomial regression model, p < 0.05). The number of An. gambiae s.l. collected was too low to enable a similarly meaningful statistical analysis, but the trends are similar. Note the different scales on the y-axes that reflect much higher densities (almost ×20) of An. funestus s.l. than An. gambiae s.l.
