Table 1 Proportion of anopheline mosquitoes caught indoors, proportion when most people are indoors, and proportion of human exposure occuring indoors for non-ITN and IRS users in Luangwa valley, south-east Zambia a

From: Human exposure to anopheline mosquitoes occurs primarily indoors, even for users of insecticide-treated nets in Luangwa Valley, South-east Zambia

Mosquito species Proportion caught indoors (Pi)b Proportion caught when most people are indoors (Pfl)c Proportion of human exposure occurring indoors (πi)d
Estimate [95% CI] p Estimate [95% CI] p Estimate [95% CI] P
An. funestus 0.586 (0.303, 0.821) 0.565 0.981 (0.881, 0.997) <0.001 0.983 (0.845, 0.998) <0.001

  1. a All models include date and household as random effects and season, village and treatment as fixed effects. For An. quadriannulatus, proportion of human exposure occurring indoors (π i ) was significantly affected by village (p = 0.0224) and the proportion caught indoors (P i ) was affected by village and season, p = 0.0177 and 0.0238, respectively. Otherwise, none of the estimates for the proportion of human exposure indoors (π i ), proportion caught indoors (P i ) and proportion caught when most people are indoors (P fl ) were not significantly affected by treatment, season or village (P > 0.05) for An. funestus, An. quadriannulatus or other anophelines.
