中文摘要 | 藍艷杉天牛 (Semanotus amethystinus (LeConte)) 原產於美國西部,以數種針葉樹為寄主。 由於鮮少危害活木,在原產地並未被視為嚴重害蟲。但本種曾數度在原產地以外地區或國家被發 現,可能是跟隨木材或包裝運輸之木料而散播。日本與紐西蘭等國已將其列為潛在的入侵木材害 蟲,成為檢疫目標。2023 年 8 月中旬第一作者於臺北市內湖好市多賣場發現一隻活成蟲,是本種 在臺灣的首筆紀錄,推測極可能是隨包裝木料直接抵達當地。由於未採集標本,無法進一步研究, 但本種的藍艷翅鞘、前胸背板基部隘縮、特別的前胸背板突紋,與不甚膨大的腿節與其他杉天牛和 相近屬種類明顯不同,故可從照片中做出鑑定。其他杉天牛屬種類也曾數度在不同國家的港口檢疫 時被攔截。建議持續監測藍艷杉天牛是否已在內湖地區建立族群。 |
英文摘要 | The Amethyst Cedar Border (Semanotus amethystinus) is native to the Western United States and targets several conifer plants as hosts. Within its native range, it is considered a minor pest as it rarely inflicts on living trees. However, instances of this species appearing beyond its natural habitat have been documented, likely due to its inadvertent transportation through lumber or wooden packaging materials. Several countries have recognized both S. amethystinus and its congeners as potential wood pests. In mid-August 2023, a live adult of S. amethystinus was sighted and photographed at the Costco Neihu store, Taipei City. This is a new record of the species in Taiwan. The likely means of its arrival was concealed within wood packaging materials. Even though the specimen was not collected, identification can be reliably accomplished using the distinctive diagnostic traits visible in the photographs. Continued monitoring is strongly recommended to ascertain whether S. amethystinus has successfully established a population in Neihu and its nearby areas. |
