%X among the epidemiological surveillance activities, risk stratification is needed in order to establish priorities in the chagas disease control program for the purpose of resource optimization. it is therefore necessary to rely on a method of high sensitivity for the detection of domestic infestation by triatomine vectors, mainly in situations of low density. in this study the results obtained with 5 capture methods were compared, 2 of passive search: gomez-nu£¿ez boxes and a4 bond paper located on the walls of the bedrooms, 2 methods of active search carried out by trained personnel: direct capture without and direct search with the aid of a flushing agent (cypermethrin + tetrametrhrin) and the collection of live triatomine vectors by the inhabitants, during 1 month. the study was carried out in 11 localities and 200 houses of portuguesa state and in 29 localities and 350 houses in barinas state. results obtained with the different methods were not significantly different in the 2 states. of the total of 550 houses explored, 132 were positive, in 131 (99.2%) the presence of bugs was detected by the inhabitants vs. 5.3% by active search: 3.38% by gomez-nu£¿ez boxes; 3.03% by flushing out search and 0% by paper. five species and 563 individuals were collected: rhodnius prolixus was the predominant species, followed by triatoma maculata, panstrongylus geniculatus and r. pictipes. the epidemiological indices of dispersion, colonization and infection to trypanosoma cruzi were calculated for each locality. results support the hypothesis of a new epidemiological scenario where, in the localities in which the domestic cycle has been interrupted, the transmission is primarily maintained by visiting r. prolixus coming in from nearby palms. the unequivocal importance of community participation in the epidemiological surveillance in the control program of chagas disease in venezuela is pointed out.
