Abstract:

With the techniques of sample plot and transect sampling, species composition of Cerambycidae in the broad-leaved Korean pine forest, coniferous forest, birch forest, and alpine tundra at different altitudes in the northern slop, western slope and the southern slope of Changbai Mountain were investigated for 8 years from 2003 to 2010. Totally 116 species of Cerambycidae, belonging to six subfamilies, 71 genera were collected. Among them, 51 species belong to Lepturinae, accounting for 43.97%; 35 species belong to Lamiinae, accounting for 30.17%; 23 species belong to Cerambycinae, accounting for 19.83%; four species belong to Spondylinae, accounting for 3.45%; two species belong to Necydalis Linnaeus, accounting for 1.72%; and one species belong to Prioninae, accounting for 0.86%. Species richness of Cerambycidae decreased from the low elevation broad- leaved Korean pine forest zone to the high elevation alpine tundra.A total of 105 species of Cerambycidae were collected in the broad-leaved Korean pine forest zone, and among them 44 species are zone endemic species, and no dominant species was found; there were 73 species collected in the coniferous forest zone, and among them eight species were zone endemic species, and two species were dominant species; a total of 29 species was collected in the birch forest zone, and among them one species were zone endemic species, and four species were dominant species; totally 18 species were collected in the alpine tundra zone, no zone endemic species was found, and 2 species were dominant species. The activity period of Cerambycidae adults were from May to September, the species was the most abundant in June and July. Cerambycidae were the most in the northern slope of Changbai Moutain, followed by the western slope, and the least in the southern slope. From the low elevation broad- leaved Korean pine forest zone to the high elevation alpine tundra, Palaearctic component had an increasing trend, while widespread component and East Asia component showed a decreasing trend. The Europe-Siberian component was predominant and East Asia component as a supplement in fauna of Cerambycidae in Changbai Mountain. According to the largest proportion of the Lepturinae collected in Changbai Mountain, Changbai Mountain would be one of the original places for Lepturinae.
