This study was investigate to ecological characteristic of Trioza ukogi (shinji) on the Acanthopanax senticosus for. inermis Harms during 2004-2005 in Korea. The sizes of Trioza ukogi (shinji) were $0.40{\pm}0.03mm$ in eggs, $0.36{\pm}0.03mm$ in 1st instar nymphs, $2.50{\pm}0.25mm$ in mature nymphs and $5.17{\pm}0.28mm$ in adults (to tip of folded wings), respectively. T. ukogi has two generations per year. First generation appeared from mid-July to late August with peak in early August. Second generation appeared from mid-September to mid-October with peak in late September. Overwintering adults move to host tree and mate from the early April to late May with peak in late April. Overwintering female laid on the new leaves and first generation prefers to lay on the seeds. The number of ovarian eggs was 5$57.5{\pm}23$.
