As a major component of cuticle wax, cuticular hydrocarbon plays key roles as a chemical cue among inter- and intra-species in some beetles like as pheromone and alleolochemicals in addition to the physical function. In this study, cuticular hydrocarbon was analyzed and compared with three species of beetles adult, Monochamus alternatus, M. saltuarius belong to the Monochamus sp., and belong to the same class, Moechophyta diphysis, a typical vector of pine wilt disease. The composition of cuticular hydrocarbon of three species of beetles adult did not show the difference between male and female in intra-species, however, showed the difference in inter-species. They also differed from carbon numbers in inter species as 25-32 in M. saltuarius, 25-35 in M. alternatus, and 23-31 in M. diphysis. Major constituent of M. saltuarius was analyzed as n-C25, 2 or 4 MeC26, 9-C25:1, n-C27, 4-MeC28, n-C29, (9,x)-,and/or (11,x)-diMeC29; those of M. alternatus were n-C25, n-C27, 4-MeC28, n-C29, (9,x)-, and/or (11,x)-diMeC29, 9-C29:1, n-C29, (9,x)-,and/or (11,x)-diMeC29; and those of M. diphysis were n-C25, n-C26, n-C27, 3-MeC27,9-C29:1, 11-MeC29. The contents of n-alkanes were as follows: M. saltuarius ≒ M. alternatus > M. diphysis. The contents of monomethylalkanes were as follows: M. diphysis > M. saltuarius ≒ M. alternatus. The contents of dimethylalkanes were as follows: M. saltuarius ≒ M. alternatus > M. diphysis. And the content of olefine in female were analyzed as follows: M. saltuarius > M. alternatus ≒ M. diphysis, and the male's contents were similar in three kinds of beetles.
