Multinomial Scan Statistics.

Here we show the main clusters of the six most abundant species in the domicile and peridomicile (Environment). Houses indicate the houses included in each spatial cluster, sand fly abundance are the observed counts and observed/expected the ratio between the sand fly counts and the expectation from the null model with a spatially homogeneous multinomial distribution. T = total, A = Lutzomyia trapidoi, B = Lu. gomezi, C = Lu. panamensis, D = Lu. olmeca, E = Lu. triramula, F = Lu. dysponeta. For the analysis we assumed the maximum cluster size to be one covering 50% of the sampled sand flies and we allowed the clusters to have ellipsoidal shapes.doi:10.1371/journal.pone.0053289.t002
