摘要

本研究調查在民國82年至84年，分別於宜蘭縣青蔥栽培區之壯圍、宜蘭市、三星等三鄉（鎮）市進行，並收集三年來之氣象資料分析，綜合三年來調查結果，青蔥受甜菜夜蛾為害之主要時期為6月至9月（7月為高峰），被害率為7.7～43.5％之間，而此時期之平均氣溫為25.2～28.5℃，相對濕度為76.6～85.1％，雨量為58～603mm／月，日照時數為4.71～7.19小時／日。經分析結果，青蔥葉片被害率與平均氣溫及日照時數呈正相關，而與相對濕度呈負相關，但與雨量關係不顯著。

This study was conducted at Juang-Wei、San-Shing and I-Lan during 1993 to 1995. We concluded that the major infestation period of the beet arymyworm on green onion was from June to September in each year with a peak in July, infestation rate was 7.7∼43.5%. In this period the mean temperature was 25.2∼28.5℃/day , humidity 76.6∼85.1%, accumulated precipitation 58.0 ∼603.0mm/month and sunshine hours 4.71∼7.19hrs/day. Analyses indicated that infestation rate was positively correlated with both temperature and sunshine, and negatively correlated with humidity , while insignificant with accumulated precipitation.
