Abstract:

Triatoma guasayana (Wygodzinsky & Abalos), a sylvatic vector of Chagas' disease, occurs in natural and peridomestic habitats of the dry Chaco region of Argentina, Bolivia and Paraguay. Ten-year retrospective spatial analyses of peridomestic T. guasayana abundance in the rural community of Amamá were expanded to the neighbouring community of Trinidad in northwestern Argentina. The distribution of T. guasayana in domiciles, peridomiciles (storerooms, chicken coops and corrals) and natural habitats (bromeliads, dry cacti and logs) around houses (i.e. 'semi-sylvatic' habitats) was analysed. The distribution of the 316 T. guasayana specimens collected in domestic and peridomestic sites during 1993-2002 was significantly clustered in both communities. Searches confirmed that the spatial distribution of semi-sylvatic and peridomestic T. guasayana was determined by the joint effects of the local abundance of goats and the density of semi-sylvatic habitats. The integration of detailed entomological and demographic longitudinal data with geographic information system data, high-resolution satellite imagery, appropriate spatial and temporal analyses and field observations allowed us to infer the underlying processes determining the distribution of T. guasayana in rural communities. This approach may be applied to other sylvatic and peridomestic vectors of Chagas' disease in order to identify high-risk areas for targeted control or environmental management. © 2008 The Authors.
