中文摘要 | 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。 |
英文摘要 | This study was conducted at Juang-Wei、San-Shing and I-Lan during 1993 to 1995. It concluded that the major infestation period of the beet armyworm 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 ~ 603mm/month and sunshine hours 4.71 ~ 7.19 hrs/day. Analyses indicated that infestation rate was positively correlated with both temperature and sunshine, and negatively correlated with umidity, while insignificant with accumulated precipitation. |
