Abstract

A Ypsolophid moth Saridoscelis sphenias Meyrick was recorded in 2020 first in Korea, and specimens were collected from Jindo and Wando in Jeonam province from 2016 to 2017. This moth uses host plants such as Pieris japonica (Thunb.) D. Don ex G. Don, Vaccinium bracteatum Thunb. and Leucothoe grayana Maxim. var oblongifolia (Miq.). This species was discovered once in a blueberry orchard in Jeju in August 2014, and since then it has been regarded as not an established species because of no further detection. However, S. sphenias was found again in blueberry orchards grown in vinyl houses in Jeju city and Seogwipo city in 2018 and 2019. Since 2020, this pest has also been found on field-grown blueberries. Hatched larvae first bored into new shoots and fed inside, and the mid-aged larvae escaped from the inside of shoots, attached several shoots with webs, and fed on the leaves in the group. It is considered that S. sphenias will become a severe pest on blueberries; thus, we report the basic life cycle here.

집나방과(Yponomeutidae)에 속한 작은상제집나방(Saridoscelis sphenias Meyrick)은 2016~2017년 전남 진도와 완도에서 채집된 개체를 동정하여 2020 국내 미기록 종으로 보고되었으며, 마취목(Pieris japonica)과 진달래과에 속한 모새나무(Vaccinium bracteatum Thunb.)와 Leucothoe grayana Maxim. var oblongifolia (Miq.)가 기주식물로 알려져 있었다. 이 종은 2014년 8월 제주특별자치도 블루베리 재배지에서 처음 발견된 후 미정착된 것으로 취급되었으나, 2018년에 이어 2019년에도 제주시와 서귀포시 여러 블루베리 농장에서 발생이 확인되었다. 그 후 2020년부터는 노지 과원에서도 발견되고 있다. 부화유충이 처음 신초 줄기 속으로 침입하여 가해하다가 중간크기로 자란 후 탈출하여 몇 개의 신초를 그물로 철하고 집단적으로 가해하는 등 특이한 피해증상이 나타난다. 향후 피해가 우려되는 해충으로 피해증상과 생활사를 간단히 보고한다.
