為達到保障太魯閣國家公園遊客之遊憩安全、提供太魯閣國家公園經營管理或解說教育方面所需的基本生物資料等多重目標，本研究自1989年3月至6月在太魯閣國家公園內，針對區內胡蜂進行定點掃網調查，共計採得胡蜂科（Vespidae）中的虎頭蜂屬（Vespa）3種，長腳蜂屬（Polistes）5種，側異腹胡蜂屬（Parapolybia）1種，鈴腹胡蜂屬（ Ropalidia ）1種，合計採得 2亞科、3族、4屬、13種的胡蜂61隻。另外還採到蜾贏（eumenids），細腰蜂（sphecids），熊蜂（bumble bee）、木椽蜂（carpenter bee）等有螫類（Aculeate）昆蟲。自1989年7月至1990年3月底止，在中部橫貫公路113 k（大禹嶺）與188k（太魯閣）間設置的46個誘引盒進行穿越線調查31次，共計調查1,426站次。計誘得虎頭蜂屬、黃胡蜂屬（Vespula）、側異腹胡蜂屬及長腳蜂屬等4屬的胡蜂2,593隻。其中虎頭蜂屬的數量最多，計捕獲2,192隻，佔所有捕獲胡蜂的84.5% (2192/2593)；黃胡蜂屬捕獲179隻，佔所有胡蜂的6.9%(179/2593)；側異腹胡蜂屬捕獲205隻，佔所有胡蜂的7.9%(205/2593)；長腳蜂屬捕獲量最少，僅有17隻，佔所有捕獲胡蜂的0.7% (17/2593)。就誘得的虎頭蜂而言，以黃跗虎頭蜂（V. velutina）的數目最多，計捕得1,075隻，佔所有誘得量的49% (1075/2192)；其次為威氏虎頭蜂（V. wilemani），計捕得598隻，佔所有虎頭蜂的27.3 (598/2192)；虎頭蜂的數量從8月起持續增加，而在10月份達到巔峰；11月份捕獲的虎頭蜂數目陡降，此後的月捕獲量更一路下滑，到3月份數量最低。 捕獲胡蜂之種類、數量、分布等資料在經營管理上代表的意義均在文中討論。

　　　　　The study of social wasps in Taroko National Park (TNP) was conducted in order to secure the safety of tourist from being stung and to provide basic biological information of these wasps for management and interpretation purposes. Social wasps in 6 areas within the territory of TNP were collected by sweep net from March to June, 1989. A total of 61 social wasps, belonging to 2 subfamilies, 3 tribes, 4 genera and 13 species, were collected. Some other Aculeates (Stinging wasps), namely eumenids, sphecids, bumble bees, carpenter bees were also found in TNP. Forty-six bait traps were set up along the Cross Island Highway (113k to 188k) to attract hornets and other social wasps. Based on a total of 1,426 trapping from July 1989 to March 1990, 2,593 social wasps belonging to 4 genera were successfully trapped. Among these social wasps, 84.5% (2,192/2,593) were hornets (Vespa spp.), 6.9% (179/2,593) were Vespula spp., 7.9% (205/2,593) were parapolybia spp. and only 0.7% (17/2,593) were Polistes spp. Of the 2,192 hornets trapped, V. velutina was the most abundant species which accounted for 49% (1,075/2,192) of the total trapped hornets. U. wilemani ranked the second highest for number and accounted for 27.3% (598/2,192) of all trapped hornets. The number of trapped nornets increased from Augnst, reached its peak in October, dropped dramatically in November, and decreased consistantly until its lowest in March. The implication of data on species, number and distribution of social wasps to Park management is discussed in detail.
