This work was done in The Biological control studies and research Center, Faculty of Agriculture, and the General Physics Laboratory, Faculty of Science, Damascus University, during the period 1/5/2014-1/92016.

The aim of this research was to extract the pheromones from the whole body of males and virgin females from the long-horned beetle borer C.dux.

by useing Gas chromatography - mass spectrometry GC-MS, Results indicated the presence of ten compounds in males, six of them belong to alkanes, and four compounds belong to Esters, Percentage of the esteric compounds ranged between 0.527% at n-hexadecanoic acid and 52.204% at 9-12-octadecadienoic acid (z-z), While eight basic compounds were found in females, six of them belong to alkanes, four of which are methyl alkanes and two compounds belong to esters, Percentage of the compounds ranged between 4.3% at 9,12,15-Octadecatrienoic Acid, Methyl Ester,(Z,Z,Z), and 20,18% at 2-Methyl- Eicosane.
