Examining of spatial distribution of coleopterous insects in the forest ecosystems of various displacement degrees plays a pivotal role for communities’ ecology. The present article is concerned with examination of the spatial stratification of the longicorn beetles (Coleoptera, Cerambycidae) in the valley-growing elm and ash forests with Korean pine and in the mountain rhododendron oak-forest. Collection of the material is carried out by standard entomologic methods using soil and window traps at 6 model sites (five sites are presented by valley-growing forests with dominating of elms, ash tree or Korean pine, and the sixth is by mountain rhododendron oak-forest) with various displacement degree. The information on species composition, habitat conditions and vertical distribution of the longicorn beetles in the forests of the South of Primorski Krai has been obtained. It has been established that the biggest number of species is concentrated in the primary forest, community structure of longicorn beetles in these forests has high similarity, which is conditioned by similar space structure of plant association and equal composition of main wood generating species, being both food items and at the same time micro sites for development of larvae of longicorn beetles. Distribution of longicorn beetles was found by the bio-geological horizons in the old-growth elm forests, the biggest number of species and maximum total abundance are marked on the middle and upper layers of forest canopies. The longicorn beetles which larvae are sapro-xylo-mycetophage are marked to belong to lower layer, and xylophages longicorn dominate at the upper layer of forest canopy.
