The effect of regurgitant from Leptinotarsa decemlineata Say larvae on wound-induced responses was studied using two plant species, Solanum tuberosum L. and Phaseolus vulgaris Wounding one leaf intact S. plants differentially affected ethylene production activities peroxidase polyphenol oxidase. Only oxidase activity stimulated by wounding in both wounded systemic leaves. Peroxidase not wounding. caused only a transient increase application to wound surfaces as well significantly enhanced leaves P. vulgaris. an amplification production, activity, bean plants. Several substances were tested for their role possible endogenous signals Hydrogen peroxide methyl jasmonate appeared potential local formation Local discs the potato versus While all concentrations stimulation discs, completely inhibited increasing discs. Our data present evidence that may play important interaction between herbivores at level recognition particular herbivore leading specific induction signalling cascades.
