Background: The sand fly Lutzomyia longipalpis is the main vector of American visceral leishmaniasis, a disease caused by parasites of the genus Leishmania. Adults of this insect feed on blood (females only) or sugar from plant sources, but their digestion of carbohydrates is poorly studied. Beta-glycosides as esculin and amygdalin are plant compounds and release toxic compounds as esculetin and mandelonitrile when hydrolyzed.

- The study investigates the feeding behavior of Triatomines, specifically Rhodnius prolixus, traditionally viewed solely as blood feeders, by offering them artificial sugar meals and tomato fruits to see if they consume non-blood sources.
- Results show that R. prolixus not only consumed sugar and plant tissue but also benefited from this diet by improving their health, increasing longevity, and reducing mortality after blood meals.
- This research suggests that local plants may provide essential nutrients for triatomine vectors, altering the understanding of their feeding habits and opening new avenues for Chagas Disease research and management.
