Compounds detected in the control PDA vial are not reported in the table.

^aDenotes that the standard of those components was analysed, and mass spectra and retention time matched closely or completely with the respective fungal volatiles.

^bDenotes that the components were identified according to the NIST library with a quality score of 60 or above, and no standards were used for comparison.

^cDenotes that the components represent a quality score value less than 60.
