Abstract

The European pepper moth, Duponchelia fovealis Zeller (Lepidoptera: Crambidae) was discovered at Gyeonggi-do, Korea in 2015 and 2016. The moth has been known as a very harmful pest of ornamental plants worldwide. Larval damages to the Euphorbia milii stems and to the Schlumbergera truncata leaves were detected. After immediate spraying of insecticides, the moth was not found at the greenhouse any more.

초록

세계적으로 관상작물의 중요한 나방류 해충의 하나인 Duponchelia fovealis Zeller가 2015년과 2016년에 경기도에서 처음으로 발견되었다. 유충이 꽃기린(Euphorbia milii)의 줄기 속을 파고 들어가거나 게발선인장(Schlumbergera truncata)의 잎을 가해하는 피해가 확인되었다. 유충과 피 해 확인 직후 합성농약을 살포하였고, 현재까지 추가적인 발견은 없었다.


    The European pepper moth Duponchelia fovealis Zeller (Lepidoptera: Crambidae) is a very harmful phytophagous pest that attacks 73 host plants including ornamental and horticultural plants (Zawadneak et al., 2015). This pest is native to the Mediterranean region and the Canary Islands and was first reported on ornamental plants greenhouse in Netherlands (Huisman and Koster, 1992). It has been widespread throughout the world including Europe, U.S.A., the Middle East, Africa, Turkey and Canada, recently (Efil et al., 2011).

    On June 30 2015, following farmer’s diagnosis request, we visited to a Euphorbia milii greenhouse located in Gwongju-si, Gyeonggi-do, the south Korea and found individuals of lepidopteran larvae near the soil surface and their damages on stem (Fig. 1). The rate of damaged plants was about 30%. We recommended emamectin-benzoate EC (5%) for controlling this pest, and we could not find any damage anymore at the field. On July 14 2016, a farmer who was cultivating Schlumbergera truncata in Yongin-si requested to visit and to diagnose the unseen damage. We found individuals of lepidopteran larva damaging leaves (Fig. 2) and the farmer immediately sprayed indoxacarb WP (10%) for control the pest. Two weeks later, we visited the greenhouse but could not find any damage anymore. The emerging adult (Fig. 3) from the larvae we collected was identified by the second author as an exotic insect pest, D. fovealis in Korea for the first time.

    We could not discover this pest in Gyeonggi-do at present, but it needs to be monitored consistently for economic horticultural crops including ornamental plants, pepper, lettuce etc.
