Interpretive Summary:

Technical Abstract: Insect-vectored Leishmania are the second most debilitating of human parasites worldwide. Related trypanosome parasites are damaging to honey bees and other pollinators. Trypanosome parasites of honey bees can be controlled by natural plant chemicals fed to their honey bee hosts. Similarly, trypanosome parasites of humans, including Leishmania, might be reduced when their insect hosts (sand flies and mosquitoes) feed on certain plant nectars. This review demonstrates that levels of plant chemicals that reduce trypanosome levels are found in plant nectars, suggesting that these plants can be used as forage to naturally reduce disease levels. Comparisons between trypanosome parasites of honey bees and humans can speed the search for effect treatments for a vital pollinator as well as human disease.
