Summary
A new live-baited adhesive trap effectively collects silvatic Triatominae (kissing bugs) in diverse habitats. This tool aids in detecting these disease vectors for ecological research and public health surveillance.
Area of Science:
- Vector ecology
- Medical entomology
- Tropical public health
Background:
- Triatominae (kissing bugs) are vectors of Chagas disease.
- Current methods for detecting silvatic populations are limited.
- Effective surveillance tools are crucial for disease control.
Purpose of the Study:
- To evaluate a novel live-baited adhesive trapping system for Triatominae.
- To assess the trap's efficacy across various ecosystems and habitats.
- To determine the system's utility for ecological and public health studies.
Main Methods:
- Large-scale field trials of live-baited adhesive traps.
- Deployment in diverse ecosystems and both arboreal and terrestrial Triatominae habitats.
- Capture and identification of Triatominae species.
Main Results:
- Successful Triatominae collection in all trials.
- Positive habitat detection rates generally exceeded 20%, reaching 48.4% in Amazonian palm trees.
- Eleven Triatominae species from genera Triatoma, Rhodnius, and Panstrongylus were captured.
Conclusions:
- The trapping system is effective for detecting Triatominae in silvatic environments.
- It offers a valuable tool for ecological research and surveillance.
- Further research is planned to optimize trap performance.
