Abstract:

A field survey showed that adults of Massicus raddei fed on sap of Quercus mongolica trunk through bitten wounds. The soluble sugar and acid contents of Q. mongolica exudates were determined with the HPLC (high performance liquid chromatography) method, and the volatile substances of the sap were determined by GC-MS (gas-chromatograph-mass spectrometer). The results indicated that soluble sugar in the sap included sucrose, glucose and fructose, among which the glucose had the highest content of 55.2 mg ·g-1. Acetic acid was the major acidic substance in the exudate without malic acid and citric acid, and its content was 9.8 mg ·g-1. Eleven volatile compounds, including acid, ester, benzene, alcohol, aldehyde, ether and alkane, were detected from Q. mongolica exudates. The 2-amino-6-methylbenzoic acid (34.31%), acetic acid (12.11%), formic acid (6.81%), diethyl phthalate (5.34%), 2,3-butanediol (3.22%), and 1,2-dichloro-benzene (2.05%) were the main components of the exudate volatiles.
