노린재목 방패벌레과에 속하는 해바라기방패벌레를 보고한다. 본 연구에서는 2013년 전국을 대상으로 형태 특징, 국내 분포와 기주식물을 조사하였다. 성충의 몸길이는 2.77-3.28 mm 이며 외관상 갈백색을 띠고 노숙약충은 황갈색을 띤다. 기주식물의 잎 뒷면에 모여 흡즙 가해하며 피해엽은 황백색으로 변한다. 해바라기방패벌레는 6월 상순부터 10월 하순까지 발생하며, 7월 상순-8월 하순에 발생최성기였다. 27개 시군에서 발생이 확인되었고 기주식물은 총 8과 24종으로 확인되었다. 주요 기주식물은 망초, 미국쑥부쟁이, 해바라기, 쑥, 원추천인국, 가지로 조사되었다.

Corythucha marmorata (Uhler, 1878), the chrysanthemum lace bug, originally distributes throughout North America. It feeds on plants in the family Asteraceae. In south central New York, it has been known as a common herbivore of Solidago spp. and Aster spp., especially Solidago altissima and Aster novae-angliae. Since the first founding of the lace bug in the western Japan (Hyogo) in 1999, it has rapidly expanded to other areas and sometimes damaged to agricultural crops such as chrysanthemum and sweet potato. In July 2012, we found the lace bug at Icheon, Gyeonggi Province, in Korea for the first time. Interestingly Aster pilosus Wild., an American exotic plant, was heavily infested with a lot of adults and nymphs of the lace bug at roadside. Subsequent survey indicates that it distributes widely in the central Korea, inhabiting a few wild plants including Erigeron annuus (L.) and Conyza canadensis (L.). In this report, we provide its morphological and molecular characteristics, distribution, host plants, and possible importance as an agricultural pest in Korea.

Corythucha marmorata Uhler was newly recorded in Korea as a invasive species at Pohang-si, Gyeongsangbuk-do, Korea in 2011 and at Changwon-si, Gyeongsangnam-do, Korea in 2012. Adults of this species show reticular forewings with a lot of transparent membranes and also show pterigoid process of paranotum with strong processes. This invasive species was originated from North America, and then intruded into Europe and Japan. This species is presumed became an epidemic horticultural pest at present and it is injuring almost of Asteraceae leaves. It was presumed that the invasion of Corythucha marmorata into Korea was prior to September of 2011.
