초록

1998년부터 2000년까지 3년간 경북사과주산지 사과원과 묘목원을 대상으로 잎말이나방류 종을 조사하였으며, 1992년부터 2001년까지 10년간 5-6개 시군의 관행사과원과 폐원에서 잎말이 나방 발생동향과 피해정도를 조사하였다. 사과원에 발생하는 잎말이나방으로는 애모무늬잎말이나방 (Adoxophyes orana), 사과무늬 잎말이나방(Archips breviplicanus), 매실애기 잎말이나방(Rhopobota unipunctana), 사과잎말이나방(Choristoneura longicellana), 복숭아잎말이나방(Acleris fimbriana), 감나무잎말이나방(Ptycholoma lecheana circumclusna), 한국잎말이나방(Archips subrufanus) 등 총 7종이 조사되었다. 이중 애모무늬잎말이나방이 매년 단연 우점종이었으며, 사과무늬잎말이나방과 매실애기잎말이나방은 특정 해에만 1-2 농가에서 다발생하였다. 1980년대 우점종은 사과무늬잎이나방과 매실애기잎말이나방이였으나, 1990년대말 우점종 변화가 이루어진 것으로 조사되었다. 10년간 관행사과원의 잎말이나방 피해정도를 조사한 결과, 평균 피해과율은 $0.67\%$였다. 과실 피해는 3세대 유충에 의해 8-10월에 집중적으로 이루어졌다.

Abstract

This study investigated the species of leafrollers in apple orchards and nursery farms in Gyeongsangbuk-do for three years from 1998 to 2000, and also examined the occurrence and damage of leafrollers in commercial apple orchards in 5-6 cities and districts for 10 years from 1992 to 2001. Total seven species of tortricidae were found in the apple orchards, which were Adoxophyes orana, Archips breviplicanus, Rhopobota unipunctana, Choristoneura longicellana, Acleris fimbriana, Ptycholoma lecheana circumclusna and Archips subrufanus. Among them, A. orana was dominant species every year, and A. breviplicanus and R. unipunctana occurred with a high density in one or two farms in some years. The dominant species in the 1980s were A. breviplicanus and R. unipunctana, but it was considered that dominant species have been changed in the late 1990s. According to the result of leafroller damage in commercial apple orchards for 10 years, the mean fruit damage rate was $0.67\%$. Fruit damage was observed frequently between August and October by third-generation larvae.
