金門昆蟲多樣性調查與名錄建立
ㄧ、研究緣起:
金門國家公園成立以來,為進行區內資源的管理與保育,曾於1998年、2000年委請學者進行昆蟲調查,主要調查目標為鱗翅目昆蟲,並曾進行較全面性的昆蟲相普查且於2004年出版金門常見昆蟲推廣書籍,然而整體而言,目前金門地區昆蟲相著墨於鱗翅目及農業害蟲,其他昆蟲科群則尚需進一步的調查鑑定,以便釐清與整合,提供為生物多樣性管理的依據。
二、研究方法與過程:
經由文獻資料蒐集與現場調查,採用掉落式陷阱法 (pitfall trap) 和落葉袋採集法 (winkler bag) 調查屬於膜翅目 (Hymenoptera) 的蟻科昆蟲與地棲性 (ground-dwelling insect) 的鞘翅目 (Coleoptera) 昆蟲,並採用D型網 (D-frame dipnet) 調查6個主要目的水棲昆蟲 (aquatic insects),此外更以掃網與馬氏網調查植食性的半翅目 (Hemiptera) 昆蟲,建立較為完整的金門昆蟲名錄。
三、重要發現:
本研究經由既有文獻資料的收集與整理,金門地區至少有超過13目93科542種昆蟲。透過本研究的現場調查鑑定,增加確定種類為13目115科597種,若包含未確認之形態種 (morphospecies),可能增加至14目123科666種。
本計畫捕獲地棲昆蟲共計8個目,以膜翅目最多,膜翅目中又以蟻科 ( 99 %) (Formicidae) 為主要組成類群,共採集到4亞科14屬24種螞蟻,其中有5種為新紀錄種,使得金門地區螞蟻種類數由原先35種 (董景生等2007)增加為40種。
各水域採獲昆蟲共計6目27科72個分類群,其中以鞘翅目種類最多,其次為蜻蛉目及雙翅目。鞘翅目中又以牙蟲科 (Hydrophilidae) 及龍蝨科 (Dytiscidae) 為主要組成類群;蜻蛉目以蜻蜓科 (Libellulidae) 最多,流水環境代表的種類如蜉蝣目 (Ephemeroptera)、?翅目 (Plecoptera) 及毛翅目 (Trichoptera) 種類極少甚至付之闕如,反應出金門地區缺少典型的流水域環境。
馬氏網與掃網紀錄中新增鞘翅目19個形態種紀錄、膜翅目16個形態種紀錄及半翅目葉蟬科 (Cicadellidae) 7個形態種紀錄。
基於已建立之昆蟲名錄,整理資料庫格式,製作出簡易的金門昆蟲資料庫,便利管理者查詢與新增使用。
Abstract
Keywords:insect checklist, ground-dwelling insect, aquatic insect
This study aims to build a checklist of Kinmen’s insects by paper review and field investigations in order to provide more information to managers. In total, 93 families and 542 species of 13 orders were documented, including 22 families and 10 species that were not formerly reported. If morphospecies are included, the list increases to 123 families and 666 species of 14 orders.
The composition of insect species in the Kinmen Islands was much influenced by Fujian, owing to its short distance to mainland Fujian. Based on "Fauna of insects Fujian Province of China", about 56 % (305 spp.) of species are shared with Fujian and 42 % (231 spp.) of species are shared with Taiwan.
Pitfall traps and winkler bags were used to collect ants (Hymenoptera) and terrestrial insects (mainly Coleoptera). Moreover, we used D-frame dipnets to collect aquatic insects and sweep sampling in the whole island.
According to previous references, more than 542 species insects were recorded in Kinmen area. Up to date, 8 orders of groung-dwelling insects were collected by pitfall trap in field. Most of insects belonging to Hymenoptera, and Formicidae are major family. There were 40 species recorded in total.
72 taxa-groups of aquatic insects were collected by aquatic sampling methods, include genera Coleoptera, Odonata and Diptera. Among mainly Coleoptera, Hydrophilidae and Dytiscidae are major families. Libellulidae dominant in Odonata.
