Title: Comparisons of Lepidoptera Species Assemblages among the different plant communities within the Long Term Ecological Research Sites in Korea

Moth data were obtained by using a 22W UV black light trap per treatment during June through September in 2005 and May, June, August and September in 2006 from our study sites. Our study areas of the Korea Long Term Ecological Research (KLTER) sites were Mt. Nam with two plant communities (Quercus mongolica, Pinus densiflora), Mt. Jiri with three plant communities (Q. mongolica, P. densiflora, Abies koreana), Mt. Wolak with three plant communities (Q. mongolica, P. densiflora, Q. variabilis), and Mt. Jumbong with three plant communities (Q. mongolica, P. densiflora, Larix kaempferi). The purpose of this study was to compare the species diversity of major plant feeders, Lepidopteran species at each forest type of the regional KLTER sites. Overall, the total numbers of species we've collected from the all KLTER sites in 2005 and 2006 were 465 species. Abundance of moths was highest at Mt. Wolak site, Mt. Jiri and Mt. Jumbong sites were the next highest, and Mt. Nam site was fewest with the five families, Arctiidae, Geometridae, Noctuidae, Notodontidae, Pyralidae. Analysis of variance (ANOVA) showed statistically significant difference at sampling date in abundance and at sampling date and site in species richness. One of ordination analyses, Nonmetric multidimensional scaling, showed distinct clusters separating the assemblages of moth found at each site but each plant community at the KLTER sites. However we could suggest that our sustainable monitoring will verify the distinct cluster with the forest type at each site, if we do keep the similar study for the more study period.
