An insect’s energy bar: the potential role of plant guttation on biological control
Plant guttation is an exudation fluid composed of xylem and phloem sap secreted at the margins of leaves of many agricultural crops. Although plant guttation is a widespread phenomenon, its effect on natural enemies remains largely unexplored. A recent study showed that plant guttation can be a reli...

| Summary: | Plant guttation is an exudation fluid composed of xylem and phloem sap secreted at the margins of leaves of many agricultural crops. Although plant guttation is a widespread phenomenon, its effect on natural enemies remains largely unexplored. A recent study showed that plant guttation can be a reliable nutrient-rich food source for natural enemies, affecting their communities in highbush blueberries. This review highlights the potential role of plant guttation as a food source for natural enemies, with a particular emphasis on its nutritional value, effects on insect communities, and potential use in conservation biological control. We also discuss possible negative implications and conclude with some open questions and future directions for research. |
