These molecules appear to attract various necrophagous animals. We tested the roles of DMS, DMDS, and DMTS as attractants of carrion beetles (Coleoptera: Silphidae: Nicrophorinae) in a 3-day experiment (220 baited pitfall traps) in an agricultural landscape in southern Bohemia. Sets of traps baited with DMTS were more successful in catching N. vespillo than sets baited with a blank. Traps containing DMDS had higher trapping success than traps containing DMS. In addition, trapping success strongly increased using DMTS in the presence of DMDS but not of DMS, suggesting a synergistic effect of DMDS and DMTS. We observed similar patterns between males and females in response to the infochemicals tested.
