Table 4 Description of the quantitative remotely-sensed and meteorological explicative variables associated with Anopheles larval densities in ponds

From: Utilization of combined remote sensing techniques to detect environmental variables influencing malaria vector densities in rural West Africa

Variable   Anopheles larval density* < 28 Anopheles larval density* > = 28 and < 47 Anopheles larval density* > = 47 and < 82 Anopheles larval density* > = 82
  n observations = 73 n = 17 n = 19 n = 18 n = 19
NDVI (mean within pond + 10 m ring) Range -0.02; 0.21 -0.12; 0.30 -0.12; 0.30 -0.12; 0.30

  1. * Larval density = number of larvae per sample (8 dips per pond per date). Categories were chosen following quantiles.
