Maize (Zea mays) is a Poaceae of great global importance, which requires great technological investment, such as the Bt events, for herbivores populational control which can cause low productivity. This study aims to create a parallel between the metabolomics behavior of a maize variety and its isoline under the influence provoked by two-spotted spider mite damage. Differences in identified ions concentration and distribution were observed as coming from the monosaccharides, jasmonic acid and methyl jasmonate ionizations, metabolites that would be directly related to the induced defense, which showed higher concentration in the Bt maize leaves, clean and infested, and in the conventional infested maize leaves. Furthermore, other two ions, m/z: 391.018 and 217.012, were observed in higher concentrations in Bt maize leaves, clean and infested, and in the conventional infested maize leaves. With the obtained data, It was possible to conclude that the maize plants, both Bt and conventional, are capable of respond to damage provoked by two-spotted spider mite infestation, and the maize Bt plants it was an expressive response in comparison to its isoline.
