超過80 %蜂類屬於非真社會性蜂,有部分物種稱為獨居蜂,其中利用現成的孔道作為築巢地點者特稱為借坑性蜂,然而因為城市發展導致天然空間資源減少,進而影響到獨居蜂繁殖。清大自然保育社使用誘引巢體(nest trap)進行生態調查,並配合服務學習課程在清華大學推行獨居蜂公寓(solitary bee hotel)設置計畫,以調查清大獨居蜂生態、保育獨居蜂族群和推廣蜂類生態教育。原先校方以師生恐懼為由拒絕設置,經過與各院協商,最後於清大設置14處獨居蜂公寓,根據為期8個月的調查結果,本文建議獨居蜂公寓的設置須在有遮雨的地方、不能接近土表,而根據觀察紀錄,獨居蜂產卵時間約集中於7月到10月,這些資料將有助於下一期的獨居蜂公寓設置。
More than 80% of bees and wasps are not eusocial insects; they are so-called solitary bees. Some of them adopt preexisting cavities to build nests, which are called trap-nesting bees/wasps. Nowadays, nesting resources are becoming less available due to urbanization, making it harder for them to survive. The Nature Conservation Association of National Tsing Hua University, Taiwan used ecological survey methods called nest traps and cooperated with service courses to conduct surveys on the campus. Our aim was to investigate the bionomics of solitary bees at the university, conserve their populations, and promote environmental education. At the beginning, the university rejected the plan because of the fear of bees/wasps expressed by professors and students. After much communication, we succeeded in setting up 14 solitary bee hotels on the campus. Our results show that the solitary bee hotels' location must be kept away from the rain and the soil surface. Additionally, the main reproduction period is from July to October. This information will help us optimize future plans to further conserve trap-nesting bees/wasps on the university campus.
