Untargeted metabolomic fingerprinting is a discovery tool for the identification of metabolites associated with the response to dietary and environmental perturbations. Direct analysis in real-time mass spectrometry (DART MS) promises to be a powerful analytical technique for high-throughput metablome analysis of insect. In this study, we used the DART MS technique to find tracers related to the origin of small brown planthopper (Laodelphax striatellus), and conducted a untargeted metabolomic fingerprinting on the wings and exoskeleton in Chinese and domestic collectives. This paper showed that DART MS metabolomic fingerprinting represents a rapid and powerful analytical strategy enabling distinguish of two different origin’s small brown planthoppers by recording metabolomic fingerprints.
