Description
Summary:.  Two sampling methods (manual capture and live‐baited adhesive traps) were compared for collecting the bug Rhodnius neglectus Lent (Hemiptera: Reduviidae: Triatominae) from palm trees, Mauritia flexuosa L. (Arecaceae), in the savanna of Brasília DF. R. neglectus was found in 19/50 (38%) of palm trees sampled. The detection rate was much higher by visual inspection and manual capture (18/50 = 36%) than by our trapping method (5/50 = 10%), although one tree was found to be positive by trapping but not by manual capture. Bugs collected manually were mostly (146/154 = 95%) found among the dead organic material in palm crowns. In combination, these sampling techniques are useful for quick detection of triatomine bug infestation in palm trees, especially in areas of high ecological value where the palms should not be cut and dissected, but arboreal Rhodnius are suspected to transmit enzootic Trypanosoma cruzi that might represent a risk of causing human cases of Chagas disease.
