Abstract
This study was conducted to investigate host plant, bionomics, and damage on Bamboo Leaf Rollers in Chonnam area. Species of the leaf rollers attacking the bamboo trees in Chonnam area were Microstega jessica (Butler) and Sinibotys evenoralis (Walker). Among these species, M. jessica (B.) and S. evenoralis (W.) were observed in Damyang but S. evenoralis (W.) alone was found in Naju and Hwasoon. Among the 4 host plant species observed, Phyllostachys nigra var. henonis S., and P. nigra M. were first recorded as host plants of M. jessica (B.), and P. nigra var. henonis (S.) as host plant of S. evenoralis (W.). The occurrence of the M. jessica (B). was once a year with the peak about late May, whereas the occurrence of S. evenoralis (W.) was 2 times a year and the peaks were early June and mid-July, respectively. The average periods of each stage of M. jessica (B.) were 8 days for egg, 293 days for larva, 16 days for pupa, and the longevity of the adult was 12 days for females and 9 days for males. The average periods of each stage of S. evenoralis (W.) were in 1st generation, 11 days for egg, 28 days for larva, 12 days for pupa, and the longevity of the adults was 18 days for females and 15 days for males; and 2nd generation was 7 days for egg, 261 days for larva, 20 days for pupa, and the longevity of the adults was 11 days for females and 10 days for males. The time of most adult emergence of M. jessica (B.) was from 6 p.m. to 4 a.m. and the peak was 8 p.m. to 10 p.m. M. jessica (B,) overwintered as 6th instals in Bamboo shoot sheath but S. evenoralis (W.) overwintered as
전남지역(全南地域) 대나무 집단재배지(集團栽培地)에 피해(被害)가 확대(擴大)되고 있는 잎말이나방류(類)의 발생(發生), 기주식물(寄主植物), 생태(生態) 및 피해(被害)에 관(關)해서 조사(調査)한 바 다음과 같은 결과(結果)를 얻었다. 1. 전남지역(全南地域)에서 대나무엽(葉)에 피해(被害)를 주는 명나방류(類)에는 줄노랑명나방(Microstega jessica (B.))과 줄허리들명나방(Sinibotys evenoralis (W.) 2종(種)이었고 담양(潭陽)에서 발생비율(發生比率)을 보면 줄노랑명나방이 96.5%, 줄허리들명나방이 3.5%이었으나 나주(羅州), 화순(和順)에서는 줄허리들명나방만이 발생(發生)되었다. 2. 기주식물(寄主植物) 조사(調査)에서 줄노랑명나방은 왕대(Phyllostachys bambusoides S. et Z.), 죽순대(P. pubescens Mazel), 솜대 (P. nigra var. henonis Stapf), 오죽(P. nigra Munro), 줄허리들명나방은 왕대, 솜대, 오죽으로 밝혀졌는데, 본조사(本調査)에서는 줄노랑명나방의 솜대와 오죽 2종(種)과 줄허리들명나방의 솜대 1종(種)이 새로운 기주(寄主)로서 확인(確認)되었다. 3. 줄노랑명나방은 담양지역(潭陽地域)에서 연(年) 1회(回) 발생(發生)하며 그 최성기(最盛期)는 5월(月)하순(下旬)이었고 줄허리들명나방은 나주지역(羅州地域)에서 연(年) 2회(回) 발생(發生)으로 그 최성기(最盛期)는 6월(月)상순(上旬)과 7월(月)중순(中旬) 경(頃)이었다. 4. 각(各) 태별(態別) 평균기간(平均期間)을 보면 줄노랑명나방은 난(卵)이 8일(日), 유충이 293일(日), 용(踊)이 16일(日), 성충수명은 자충이 12일(日), 웅충이 9일(日)이었고, 줄허리들명나방은 1화기(化期)는 난(卵)이 11일(日), 유충이 28일(日), 용(踊)이 12일(日) 성충수명은 자충이 18일(日), 웅충이 15일(日)이었으며 2화기(化期)는 난(卵)이 7일(日), 유충이 261일(日) 용(踊)이 20일(日), 성충수명은 자충이 11일(日) 웅충이 10일(日)이었다. 5. 1일중(日中) 줄노랑명나방의 성충우화시간을 보면 저녁 6시(時)부터 새벽 4시(時)까지였고 그 Peak는 밤
