As a result of investigation on the larvae attacking leaves of Eucommia ulmoides Oliv. and causing serious damage on the plant in Seoul, Chungnam and Jeonbuk Province in Korea during summer in 2013, Protegira songi Chen & Zhang of the family Noctuidae was identified. In this study, we report the host plants of it for the first time from Korea, with larval damage and taxonomic information by illustrating the characteristics of male and female genitalia. Also we will conduct to extract and analyse the DNA barcode for correct identification in forest pest monitoring in near future.

Several plant growth regulators were examined for on their effect on the in vitro propagation of Kalopanax pictus(THUNB.) (NAKAI.) on WPM medium. Among the cytokinins tested, BA at 13.32 μM appeared to be the most effective for multiple axillary shoot formation. Although the addition of 2.89 μM GA3 promoted stem elongation, it produced morphologically abnormal leaves and stems. For rooting of the shoots, 4.9 μM IBA seemed to be more effective than 2.69 μM NAA. When the regenerated plants were transferred on artificial mixture containing vermiculite and peat-moss (1 : 1, v/v), 81% of them survived and grew normally.
