Naïve indices of infestation (given as percentages) by Chagas disease vectors in 414 man-made ecotopes of the lower Jaguaribe valley in northeastern Brazil after three vector-search rounds.

n, number of ecotopes sampled within each class; ‘All detections’ include the detection of only fecal streaks identified (perhaps incorrectly) as those of triatomine bugs, whereas detections were considered ‘certain’ when at least one triatomine bug or exuvia (molted ‘skin’) were found and identified without doubt; S1 to S3, first to third vector-search rounds; Combined, combined results of all three vector-search rounds (percentage of ecotopes with at least one detection in at least one search round).Naïve indices of infestation (given as percentages) by Chagas disease vectors in 414 man-made ecotopes of the lower Jaguaribe valley in northeastern Brazil after three vector-search rounds.
