A survey is given of the different places explored in the search for extra-domestic Rhodnius prolixus, the methods used, and the results observed during more than one year of work in large rural areas of the state of Guarico, Venezuela. It is shown that R. prolixus was found in all its evolutional stages in authentically extradomestic places represented by various kinds of palm trees and herons' nests. The methods followed to confirm in the laboratory the species of R. prolixus as well as the species of Trypanosoma cruzi in insects captured on palm trees and in herons' nests is described. Natural infection with T. cruzi is proven only in those specimens of R. prolixus captured on palm trees, while no infection with T. cruzi could be found until now among those captured in herons' nests. Through this survey, knowledge of the ecology of R. prolixus - principal vector of Chagas's disease in Venezuela - is significantly widened, and the aspect of its extra-domesticity is of fundamental importance in the strategy of the campaign against this vector(AU)
