| 中文摘要 | 由 Xylella fastidiosa 引起的臺灣葡萄皮爾斯病最早於 2002 年發現,陸續於中部葡 萄產區進行偵測調查後,確認有苗栗縣通霄鎮、卓蘭鎮、臺中市外埔區、后里區、 東勢區、新社區、豐原區、南投縣草屯鎮、竹山鎮及集集鎮等 10 個疫區,而彰化葡 萄產區則未偵測到皮爾斯病發生。後續花費 10 年執行緊急防疫措施後,有效降低皮 爾斯病的發生與擴散。本研究於 2023-2024 年針對 10 個疫區重啟監測調查,以確認 夏果期及冬果期皮爾斯病發生現況。調查過程中採集了葡萄園鄰近地的 7 種替代性寄 主植物及媒介昆蟲白邊大葉蟬的樣品進行帶菌檢測。本研究於夏果期共調查了 337.4 公頃 2,379 處葡萄園約 54 萬株葡萄,在冬果期共調查 177.4 公頃 856 處葡萄園約 28 萬株葡萄,共監測到 8 處罹病園。在調查到的 59 個罹病株中,有 3 株位於卓蘭 2 處 罹病園、53 株位於外埔 4 處罹病園及 3 株分布於新社 2 處罹病園。另外,本研究調 查了 7 種替代性寄主植物雙輪瓜 (Diplocyclos palmatus)、漢氏山葡萄 (Ampelopsis brevipedunculata var. hancei) 、葎草 (Humulus scandens) 、白匏子 (Mallotus paniculatus)、玉珊瑚 (Solanum pseudocapsicum)、山黃麻 (Trema orientalis) 及小花 蔓澤蘭 (Mikania micrantha) 共 645 株,於卓蘭、外埔、后里及新社監測到 10 株帶菌 樣本,分別為小花蔓澤蘭 1 株、漢氏山葡萄 8 株及白匏子 1 株。媒介昆蟲白邊大葉蟬 (Kolla paulula) 蒐集了 431 隻,共監測到 14 隻帶菌蟲體,6 隻採自卓蘭、8 隻採自外 埔;調查結果顯示本病菌仍零星存在於罹病葡萄植株、替代性寄主植物及媒介昆蟲 白邊大葉蟬,病原菌可融入當地生態環境,已於臺灣葡萄產區建立穩定族群。 |
| 英文摘要 | Pierce’s disease (PD), caused by Xylella fastidiosa, was first discovered in Taiwan in 2002. Following this discovery, an official disease monitoring and control program was launched in central grape production areas of Taiwan. This program confirmed that ten local districts had PD infestations, including Tongxiao, Zhuolan, Waipu, Houli, Dongshi, Xinshe, Fengyuan, Caotun, Zhushan, and Jiji. (PD was not detected in the Changhua grape production area.) Nonetheless, after a decade of emergency phytosanitary measures, the occurrence and spread of PD were considered effectively reduced by 2012. This study, conducted from 2023 to 2024, restarted monitoring surveys in the ten districts which were previously infested with PD. Our objective was to confirm the current status of PD during summer fruit and winter fruit periods. For this, samples were collected from seven species of alternative host plants for the PD pathogen and the insect vector Kolla paulula. Sample collection was conducted in the vicinity of vineyards. During the summer fruit period, surveys covered 337.4 hectares, including 2,379 vineyards and approximately 540 thousand grapevines. During the winter fruit period, surveys covered 177.4 hectares including 856 vineyards and approximately 280 thousand grapevines. We found a total of eight infested vineyards and 59 diseased grapevines. Specifically, there were two infested vineyards with 3 diseased grapevines in Zhuolan; four infested vineyards with 53 diseased grapevines in Waipu; and two infested vineyards with three diseased grapevines in Xinshe. Among the 645 alternative host plant samples we surveyed, ten samples (collected from Zhuolan, Waipu, Houli, and Xinshe) were PD-postive. These samples included one bitter vine (Mikania micrantha), eight porcelain berry (Ampelopsis brevipedunculata var. hancei), and one balik angin (Mallotus paniculatus). Out of the 431 K. paulula samples we collected, 14 were identified as carrier vectors (with six in Zhuolan and eight in Waipu, respectively). Our surveys indicate that X. fastidiosa still sporadically exists in diseased grapevines, alternative host plants, and the insect vector K. paulula. These findings in turn suggest that the PD pathogen has established stable populations in grape production areas of Taiwan. |
