Table 1. Parameters of the spatially explicit modelling, hypotheses to be tested and parameter values used in the analysis.
Parameter description | Hypotheses | Parameter values |

(jj) equal | dd = dp ∈ [0,1] | |
Mode of the distribution of dispersal distances (D) | (k) modal distribution | ]0–500] |
(kk) centred distribution | 0 | |
SD of the distribution of dispersal distances (σ) | None | ]0–500] |

(ll) no attraction by houses | 1 |
Parameter values are given for a 15 days period, which corresponds to the time step of the models. Parameters were allowed to vary in the indicated range of values to best fit the data with each of the 6 nested models defined with respect to hypotheses i-ii-iii, j-jj, k-kk, l-ll (as described in section ‘Hypotheses on the origin and dispersal patterns of triatomines’).
