本研究探讨了为科学研究寻找熊蜂巢穴的替代方法。我们目前的结果，从三个试验，旨在评估：1。两种探测犬的探测效率比较; 2.狗的能力，找到巢穴时，进行重复搜索的农业栖息地通过季节; 3。狗和人类志愿者在林地中寻找巢穴的效率进行了比较，人类志愿者使用两种方法：“固定搜索”和“自由搜索”。两种狗在寻找大黄蜂巢穴材料的掩埋部分时的效率不同（62.5%和100%正确指示）。搜索真实的巢在农村的栖息地，探测狗位于9个巢的四个大黄蜂物种，在一系列的栖息地，在一个巢的速度为19小时24分钟的搜索时间。比较“自由搜索”使用人类志愿者和狗在林地中发现，他们以类似的速度，一个巢1小时20分钟的搜索时间。固定搜索巢更慢（一个巢3小时18分钟的搜索时间），但可能提供一个可靠的估计巢密度。有经验的志愿者的表现并不比新手好。考虑到训练和维护探测犬所需的投资，我们得出结论，这不是一个成本效益高的方法来定位熊蜂巢。如果目标是估计密度，那么固定搜索是合适的，而如果目标是找到许多巢穴，使用志愿者的免费搜索提供了最具成本效益的方法。
This study investigates alternative approaches to locating bumble bee nests for scientific research. We present results from three trials designed to assess: 1. The comparative efficiency of two detection dogs; 2. The ability of a dog to locate nests when carrying out repeat searches of agricultural habitats through the season; 3. The efficiency of a dog compared with human volunteers at finding nests in woodland, with the human volunteers using two methods: 'fixed searches' and 'free searches'. The two dogs varied in their efficiency in finding buried portions of bumble bee nest material (62.5% and 100% correct indications). Searching for real nests in rural habitats, a detection dog located nine nests of four bumble bee species, in a range of habitats, at a rate of one nest for 19 h 24 min of searching time. A comparison of ` free searches' using human volunteers and the dog in woodland found that they located nests at similar rates, one nest for 1 h 20 min of searching time. Fixed searches located nests more slowly (one nest for 3 h 18 min of searching time), but probably provide a reliable estimate of nest density. Experienced volunteers performed no better than novices. Given the investment required to train and maintain a detection dog, we conclude that this is not a cost effective method for locating bumble bee nests. If the aim is to estimate density, then fixed searches are appropriate, whereas if the aim is to find many nests, free searches using volunteers provide the most cost effective method.
