Plants release a variety of volatile organic compounds that play multiple roles in the interactions with other plants and animals. Natural enemies plant-feeding insects use these volatiles as cues to find their prey or host. Here, we report differences between blends tomato infested whitefly Bemisia tabaci borer Tuta absoluta. We compared emission of: (1) clean plants; (2) T. absoluta larvae; (3) B. adults, nymphs, eggs. A total 80 were recorded which 10 occurred consistently only headspace absoluta-infested plants. Many detected two herbivory treatments emitted at different rates. damaged by least times higher levels many intact The multivariate separation from those was due largely chorismate-derived well metabolites C18-fatty acids branched chain amino had rates plants, whereas cyclic sesquiterpenes α- β-copaene, valencene, aristolochene significantly tabaci-infested Our findings imply feeding induced differ quantitatively qualitatively, providing chemical basis for recently documented behavioral discrimination generalist predatory mirid species, natural employed biological control.
