摘要: Tomato is susceptible to pest infestations by both spider mites and aphids. The effects of each individual on plants are known, whereas multiple-pest have received little interest. We studied the single- versus infestation Tetranychus urticae Myzus persicae tomato biochemistry (Solanum lycopersicum) combining a metabolomic approach analyses carotenoids using UHPLC-ToF-MS volatiles GC-MS. Plants responded differently aphids after 3 weeks infestation, multiple induced specific metabolite composition in plants. In addition, we showed that emissions differed between adaxial abaxial leaf epidermes identified compounds emitted particularly response (cyclohexadecane, dodecane, aromadendrene, β-elemene). Finally, carotenoid concentrations leaves stems were more affected than single infestations. Our study highlights discusses interplay biotic stressors within terpenoid metabolism.
