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.
