Successional and native forests predict the occurrence and infection status of Chagas disease vectors in Panama

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Findings here show that successional forest predicts greater kissing bug infestation risk in palm trees, whereas native forest predicts lower kissing bug occurrence but greater infection with T. cruzi. These insights can guide land use planning towards vegetation management practices that help minimize T. cruzi transmission risks for rural communities.
