The Asian larch bark beetle, I. subelongatus Motschulsky, is a severe pest of various Larix species in its natural range. This study reports the degree similarity among cuticular hydrocarbon (CHC) profiles six populations northeastern China. Thirty individual or isomeric mixtures hydrocarbons were identified by solid-phase microextraction (SPME) coupled with gas chromatography–mass spectrometry (GC–MS). components consist straight-chain alkanes, alkenes, and methyl-branched carbon chain lengths ranging from 24 to 31. Among these, four CHCs (n-C25, 9-C27:1, n-C27, 3-meC27) can serve as chemotaxonomic markers identify subelongatus. No qualitative differences detected between males females any populations, but significant quantitative observed some CHCs. Phylogenetic analysis based on CHC showed only minor compared partial mtDNA COI sequences regarding beetle affinity. These results establish rapid method provide basis for further investigations into functions
