    Chemical composition of volatiles emitted from fresh mouse carcasses was studied using solid-phase micro-extraction, 2D-gas chromatography with TOF-MS detection and gas chromatography with electroantennographic detection. Electroantennography and laboratory olfactometric behavioral observations were used to study the antennal sensitivity to identified infochemicals and their attractiveness for burying beetles Nicrophorus vespillo and Nicrophorus vespilloides. Chemical analysis showed that mouse carcass emits following sulphur-containing chemicals: methanethiol, methyl thiolacetate, dimethyl sulphide, dimethyl disulphide and dimethyl trisulphide. EAG measurements revealed antennal sensitivity to these compounds. Behavioral tests in laboratory olfactometer showed that dimethyl sulphide, dimethyl disulphide and dimethyl trisulphide are highly attractive to both studied species.
