Environmental changes such as land-use change including reclamation cause effects on the ecosystem seriously. Present study investigated community structure of hemipterans in several reclaimed lands from western coast of South Korea in 2010, because among arthropods, hemipterans are more influenced by land-use change which caused the change of dominant plants. Six reclaimed lands were selected for our study based on the ages of reclaimed land (0, 5, 12, 16, 20, and 31 years). Dominant plant species of reclaimed lands were belonging to Poaceae, Phragmites communis and Oryza sativa in Yeongsangan II, Sabkyocheon, Geumgan I and Gyehwado, Secale cereale in Seokmun, and Imperata cylindrica and Calamagrostis epigeios in Sihwa. A total of 31 species in 10 families were identified from 4475 collected hemipterans. In Sihwa, Shannon’s diversity was very low compared to other 5 reclaimed lands due to dominance of Paromius exiguus. Because I. cylindrica and C. epigeios were 1st and 2nd host plants of P. exiguus (2824 individuals only collected from Sihwa). In multivariate analysis, 6 reclaimed lands grouped into 2 major groups showing 49.8% in Bray-Curtis similarity between 2 groups. From these results, land-use change such as reclamation project may cause the outbreak of insect pests by destruction of ecosystem functions and simplification of plant community, although community structure of hemipterans may be stable over age of land reclamation.
