Determinants of the domiciliary density of Triatoma infestans, vector of Chagas disease
Abstract. In two heavily infested rural villages of Santiago del Estero, Argentina, where no indoor‐spraying with residual insecticides had ever been carried out by official control services, we studied the influence of roof and wall structure, domestic use of insecticide, family size and the number...

In two heavily infested rural villages of Santiago del Estero, Argentina, where no indoor‐spraying with residual insecticides had ever been carried out by official control services, we studied the influence of roof and wall structure, domestic use of insecticide, family size and the number of domestic dogs, on the domiciliary density of Triatoma infestans (Klug). Bug density was significantly associated with (1) the interaction between insecticide use and type of roof, (2) the structure of indoor walls, (3) the number of dogs sharing sleeping areas of people (room‐mate dogs), and (4) the number of people plus room‐mate dogs, but not with just the number of people resident in the house. The interaction between insecticide use and a roof made of ‘simbol’, a locally available grass (Pennisetum sp.), also reflected a younger age structure of domestic bug populations. In infested houses, the density of bugs infected with Trypanosoma cruzi Chagas was significantly correlated with overall bug density. Our data suggest that the application of environmental management measures by the affected people, such as plastering of walls and modification of roofs, coupled with keeping dogs away from bedrooms and application of insecticides, should limit the domestic population density of T.infestans and thus reduce the transmission of T.cruzi to people.
