Attraction of canthon vazquezae (Coleoptera: Scarabaeinae) to volatiles released by messicobolus magnificus (Diplopoda: Spirobolida)
Dung beetles of the Scarabaeinae subfamily are present in temperate and tropical ecosystems. Some species of these insects feed on millipede carcasses. The objective of this study was to determine the attraction of Canthon vazquezae to volatiles released by Messicobolus magnificus. The bioassay was performed using a Y-glass tube olfactometer. Canthon vazquezae was significantly attracted to dead M. magnificus, as well as stressed and wounded individuals. In contrast, unstressed M. magnificus did not attract C. vazquezae. The volatiles released by M. magnificus in stressed, wounded, and dead states were analyzed by gas chromatography coupled to mass spectrometry (CG-MS). Six compounds were tentatively identified as 2-methyl-p-benzoquinone, trimethyl-p-benzoquinone, 1,2,4-trimethoxybenzene, 2-methyl hydroquinone, 2,5-dimethoxythiophenol, and 3,4-dimethoxyphenol. Some of these compounds have been identified as attractants to other coleopterans.
