The spatial-temporal analysis of the abundance of insects, vectors of tegumentary leishmaniasis (TL) and visceral leishmaniasis (VL),was performed in Argentina using spatial-temporal increasing scales.In the microscale(microfocal), the eﬀect of the primary vegetation-crop interface in vector abundance was observed, and also how the shelters, food sources, and other environmentalcharacteristics contribute to habitat microheterogeneity and so to a microheterogeneous vector distribution. In the mesoscale (locality or epidemic focus), the results from diﬀerent foci of TL(rural and periurban) and VL(urban) suggested a metapopulation structure determined partially by quantiﬁable habitat variables that could explain the increase of risk associated to an increase ofvector-human contact due to climatic or anthropogenic changes. In the macroscale (regional), captures of vectors and records of human cases allowed the construction of risk maps and predictive models of vector distribution. In conclusion, in order to obtain valid results transferrable to control programs from spatial studies, special attention should be paid in order to assure theconsistency between the spatial scales of the hypotheses,data,and analytical tools of each experimental or descriptive design.
