Detecting domestic vectors of Chagas disease: A comparative trial of six methods in north-west Argentina
Six methods for detecting domestic infestations by triatomine bugs were compared in the rural community of Amama, north-west Argentina. An average of three pairs (range, 2-5 pairs) of sensor boxes and sheets of pink typing-paper were tacked to the walls of human sleeping areas in 45 houses for 30 da...

Six methods for detecting domestic infestations by triatomine bugs were compared in the rural community of Amama, north-west Argentina. An average of three pairs (range, 2-5 pairs) of sensor boxes and sheets of pink typing-paper were tacked to the walls of human sleeping areas in 45 houses for 30 days and then inspected by a two-man team. Triatoma infestans bugs were collected in bedrooms by a different two-man team aided by a flushing-out agent both before and after application of sensing devices. Finally, knockdown collections of bugs after application of one insecticide fumigant canister per bedroom were also made. The proportion of houses with evidence of current domestic bug infestations that were detected by the various methods were as follows: sensor boxes (95.3%), reports of householders (88.4%), knockdown (87.8%, paper-sheets (86.0%), and flushing-out (69.8-76.7%).
