- Abstract
Chagas disease is a key vector-borne disease. This illness is caused by Trypanosoma cruzi Chagas, which is transmitted by triatomine bugs. Largely, the control of this disease relies on reducing such contact. We optimized the performance of a box trap in laboratory conditions to capture four triatomine species: Triatoma pallidipennis (Stål), Triatoma infestans Klug, Triatoma phyllosoma (Burmeister), and Rhodnius prolixus Stål. We varied four components for a box trap: material, color, height, and bait attractants. All species were captured more in corrugated cardboard traps than in other trap material. Moreover, T. infestans and R. prolixus were also captured in plywood traps. T. pallidipennis preferred traps of 15 × 15 × 4 cm and 20 × 20 × 4 cm, while T. phyllosoma and T. infestans were more captured in traps of 10 × 10 × 4 cm, and 15 × 15 × 4 cm. Rhodnius prolixus was more captured to 10 × 10 × 4 cm traps. T. pallidipennis was trapped with traps of any color tested, T. phyllosoma and T. infestans were captured more in red and yellow traps, and R. prolixus was mostly captured in blue, violet, and yellow traps. Triatoma pallidipennis was captured at any height above the ground, while T. phyllosoma, T. infestans, and R. prolixus were mostly captured 50, 100, and 150 cm above the ground. Regarding the lure, T. pallidipennis was trapped with four aldehydes + lactic acid + ammonia; T. infestans and R. prolixus were trapped with a blend of four aldehydes + lactic acid, a blend of the four aldehydes + ammonia, and a blend of four aldehydes + lactic acid + ammonia. Triatoma phyllosoma was trapped with any lure tested. These results showed that the trap boxes offer an alternative method for controlling Chagas disease., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.
