Phytochemical defense responses of plants are often herbivore-specific and can be affected by a herbivore’s feeding mode. However, comprehensive studies documenting the impact of multiple herbivores from different feeding guilds on induced phytochemical responses in distal leaves and its consequences for plant-mediated herbivore interactions are limited and findings are inconsistent. We investigated how herbivory by leaf-chewing caterpillars, cell-content feeding spider mites and phloemfeeding aphids and whiteflies affect secondary metabolomes and phytohormone levels in youngest, non-damaged cotton leaves (distal leaves). Furthermore, bioassays with caterpillars were conducted to assess their performance on distal leaves of plants infested with different herbivores. Caterpillars, and to a lesser degree spider mites, led to a systemic induction of terpenoids with negative consequences for caterpillar performance in the bioassays. Both herbivores reduced levels of various nutrients and potentially antioxidative compounds. Caterpillar damage increased levels of jasmonoyl-L-isoleucine and abscisic acid (ABA), whereas spider mite infestation had no effect on phytohormone levels. Aphid and whitefly infestation did not systemically affect secondary metabolites. Aphids decreased salicylic acid levels while whitefly-infested plants contained increased ABA levels. Neither aphid nor whitefly infestation affected caterpillar performance. In general, feeding mode of a herbivore can affect systemically induced changes in phytochemistry and plant-mediated indirect interactions even though the two phloem-feeding herbivores triggered different phytohormonal responses. The observed reduction of nutrients and potentially antioxidative compounds upon caterpillar and spider mite herbivory underlines the importance of further elucidating the role of resource sequestration as a potential systemic defensive response following herbivory by chewers and cell-content feeding herbivores.
