The novel method of matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) allows to uncover functions of surface-occurring glucosinolates e.g. as oviposition clues for female moths during egg-laying. Similarly, spatial distribution fatty-acid-derived semiochemicals can be determined on fruit flies cuticles which actually matched with their expected biological function. The developed protocol can be further used to study other classes of chemicals presented on a biological surface helping to understand the chemical communication between organisms.
