Abstract (English): Introduction: Despite of indoor insect control measures, American trypanosomiasis cases still occur, with the participation of both peridomestic and sylvan species. One of these species is Rhodnius robustus, which has been found naturally infected with Trypanosoma cruzi and Trypanosoma rangeli. Objective: To describe the feeding behavior of R. robustus under laboratory conditions. Materials and methods: We analyzed time spent for repletion, the number of defecations, the percentage and number of times insects defecated during blood intake, and the weight gained after blood feeding in each nymph stage of R. robustus. Results: Repletion for R. robustus took between 19:26 to 44:55 (minutes:seconds) and all nymph stages defecated during blood feeding. The proportion of individuals which defecated during blood feeding varied between 13.3% and 93.3%. On the other hand, the highest average blood intake was observed in the fifth stage (337.19 mg), which is twice the blood intake of adults (161.25 mg). Conclusions: All stages of R. robustus dejected during blood feeding, which is an important factor for its vectorial competence. Nevertheless, the time prior to the first dejection, the percentage of dejections and number of individuals that dejected upon blood feeding, as well as the amount of ingested blood varied among stages, which means that feeding behavior is mediated by variables depending on age/stage.

Abstract (Spanish): Introducción. A pesar del control de los insectos domiciliados, se siguen presentando casos de enfermedad de Chagas con la participación en la transmisión de especies peridomiciliarias y selváticas, una de las cuales es Rhodnius robustus, especie reportada con infecciones naturales de Trypanosoma cruzi y T. rangeli. Objetivo. Describir el comportamiento de R. robustus durante su alimentación en condiciones de laboratorio. Materiales y métodos. En cada estadio de desarrollo de R. robustus se analizó el tiempo promedio para alcanzar la repleción, número promedio de deyecciones, porcentaje de individuos que defecan durante la comida y ganancia de peso después de la alimentación. Resultados. Rhodnius robustus tardó entre 19:26 y 44:55 (minutos:segundos) en alimentarse a repleción; los insectos defecaron en todos sus diferentes estadios durante la alimentación. El porcentaje de individuos que defecan durante la alimentación varía de 13,3 % a 93,3 %. Por otro lado, el consumo promedio de sangre en el quinto estadio, 337,19 mg, duplica la cantidad ingerida por los adultos, 161,25 mg. Conclusiones. En todos los estadios de R. robustus hay defecación durante la alimentación, factor que favorece su competencia vectorial. Sin embargo, el tiempo para la primera deyección, el porcentaje de deyecciones y los individuos que defecan durante la comida, así como la cantidad de sangre ingerida, varían entre los estadios, lo cual indica que el comportamiento alimenticio está mediado por variables dependientes de la edad/estadio.
