Trehalose in Tea Aphid Honeydew Enhances the Performance of a Chewing Herbivore on Tea Plants by Suppressing Plant Defence and Increasing Leaf Water Content

Summary statement Toxoptera aurantii honeydew enhances Ectropis obliqua fitness by reducing defensive catechins in leaves of Camellia sinensis via JA‐independent manner. Honeydew‐derived trehalose reduces defensive catechins in leaves while boosting leaf water content, promoting larval growth of E. obliqua .
