ZARBIN, Paulo H. G. et al. Alarm pheromone system of stink bug Piezodorus guildinii (Heteroptera: Pentatomidae). J. Braz. Chem. Soc. [online]. 2000, vol.11, n.4, pp. 424-428. ISSN 1678-4790. http://dx.doi.org/10.1590/S0103-50532000000400017.
The compounds utilized by the soybean stink bug Piezodorus guildinii as alarm pheromone were characterized by analysis of the chemical composition of the metathoracic scent gland secretions from adult bugs. In addition to characteristic hydrocarbons, (E)-2-hexenal and (E)-4-oxo-2-hexenal were detected as major constituents. These compounds were previously described as alarm pheromone in several other pentatomid species.
Keywords : Piezodorus guildinii; alarm pheromone; (E)-2-hexenal; (E)-4-oxo-2-hexenal.
