中文摘要 | 大田鱉屬於昆蟲網(Class Insecta) 、有翅亞綱(Apterygota) 、外生翅群(Division Exopterygota)、半翅目(Order Hemiptera)、隱角椿象亞目(Nepomorpha) 的田鱉科(Belostomatidae)Lethocerus 屬;已知臺灣之大田鱉有印度大田鱉(Lethocerus indicus Lepeletier and Serville)及日本大田鱉(Lethocerus deyrolli Vuillefroy)二種。為肉食性,會獵食水中的小型脊椎動物及無脊椎動物(楊、黃1992; 董等2014)。近年因人為開發,池沼棲地破壞;農業大量使用農藥,造成水源污染,致使大田鱉族群數量驟減甚至幾近消失。本研究旨在調查大田鱉族群之現況, 包括分佈地點及族群數量資料, 以及國內館藏標本檢視。本研究自2009年四月至2010年三月進行嘉義縣、市、雲林縣、彰化縣市、臺南市、高雄市、屏東縣市、臺中市及金門縣、各鄉鎮共計190個樣點之野外調查, 並對其中14個重要樣點持續監測至今。除直接進入水域採集外並藉由查訪之輔助,推測出過往之分佈地點,調查結果顯示,台灣中、南部僅於台南縣玉井鄉成功發現族群, 其餘縣、市之大田鱉族群可能僅存極少數或是已經完全消失。 |
英文摘要 | The giant water bug (Lethocerus indicus Lepeletier and Serville) is belongs to Hemiptera, Be10stomatidae, Genus Lethocerus, is the largest aquatic insect in Taiwan. Lethocerus indicus and L. deyrolli Vuillefroy are the only two species found in Taiwan. Both of them are carnivorous and predate small vertebrate and invertebrate animals in water. Due to the human development, water body was destroyed, and water contaminated with chemical pesticides, had caused the population declined dramatically and nearly disappeared. In order to understand the current status of giant water beetle pou1ation status, a survey was conducted from April, 2009 to March 2010 in the wild. A total of 190 sampling sites from Chiayi, Yulin, Changhua, Tainan, Kaohsiung , PingTung, Taichung, and Kimen islands were chosen for giant water bug population dynamics and distribution investigation. Besides direct sampling in the water body, historical review was also included in the following study. Only two sites had found L. indicus and L. deyrolli and the above data have suggested that these two insects might be endangered in the wild in Taiwan. |
