Abstract: The pine wood nematode (PWN), Bursaphelenchus xylophilus, causes pine wilt disease in Japan and China. Based on our past studies we believe that this pathogen is a threat to coniferous forests in the Russian Far East (Kulinich, Orlinskii, 1998). The main goals of our studies have been to survey coniferous forests for PWN, and related nematodes, living in the wood (trunks and branches) of trees. The results presented here are based on a material collected from 1992-2004 in the Russia Far East (Primorski Territory, Amurski region, Magadanski region). Surveys were made of forests of Pinus sylvestris, P. koraensis, P. sibirica, Larix sibirica, Pinus ajanensis and Abies nephrolepis. The nematodes found in wood tissue of these tree species included 28 species of 21 genera, i.e.: Deladenus, Gymnotylenchus, Neoditylenchus, Stictylus, Cephalenchus, Bursaphelenchus, Laimaphelenchus, Parasitaphelenchus, Ektaphelenchus, Aphelenchoides, Paraphelenchus, Panagrobelus, Diastolaimus, Cornilaimus, Rhabdontolaimus, Micoletzkya, Parasitorhabditis, Panagrolaimus, Macrolaimus, Geomonhystera and Plectus. Noteworthy high population densities were recorded for nematodes from the orders Tylenchida and Aphelenchida (nematodes per 10 g of wood): Bursaphelenchus (500-120000), Aphelenchoides (150-500), Laimaphelenchus (300), and Deladenus (up to 1000). No PWNs, Bursaphelenchus xylophilus, have been found. Among rhabditids, the highest population densities (nematodes per 10 g of wood) were recorded for Panagrolaimus spp. (3000) and Parasitorhabditis spp. (4000). The nematode fauna was most variable in wood of Pinus koraensis. A catalogue of the wood-inhabiting nematodes of conifer trees and their geographic distribution in the Primorski Territory of the Russian Federation has been prepared.
