Orius spp. are promising natural enemies for control of thrips, harmful insect pests of vegetables. It is, however, extremely difficult to identify adult females of Orius spp. by their appearance. The composition of cuticular hydrocarbons in O. strigicollis, O. minutus and O. sauteri were analyzed by GC-MS. Major components were C_27:1 and 2-MeC₂₈ for O. strigicollis, C_29:1, 2-MeC₂₈ and 2-MeC₃₀ for O. minutus and 2-MeC₂₈, 2-MeC₃₀ and C_33:1+2 for O. sauteri. The unique hydrocarbons were C_25:1+2 for O. strigicollis, C_29:2 and 2-MeC₃₂ for O. minutus and C_33:1+2 and C_35:1+2 for O. sauteri. We concluded that it is possible to identify these three species by a difference in composition of components of the cuticular hydrocarbons by GC.
