    本文係利用1982 至2002 年水稻害蟲偵察田及誘蟲器材調查資料,分析白背 飛蝨在嘉義㆞區稻田之族群變動、影響族群發生豐度因子並藉以建立發生預測模 式,結果顯示白背飛蝨近年來之發生族群密度有逐年增加之趨勢,可能受海外遷 入蟲數增多所致。 The white-backed planthopper (abbr. WBPH) (Sogatella furcifera (Horvath), Homoptera: Delphacidae) is an important insect pest of rice in Taiwan occasionally. Present study was conducted to investigate its population fluctuations, to determine the factors affecting abundance, and to develop the models for forecasting its population abundance based on the data collected from the monitored fields and traps from 1982 to 2002 in Chiayi region.
