我们使用巢穴识别作为模型系统来测试动物如何区分复杂的气味混合物。嗅觉辨别在许多动物物种的社会识别中是重要的，然而动物用来解释嗅觉社会信号的方法却知之甚少。我们的第一个假设是，当接触到提示化合物时，一只保护性蜜蜂会发展出一种新的识别模板（用于区分巢伴和非巢伴的信息）。这些数据支持了守卫蜂可以采用新模板的结论。我们的第二个假设是，一只蜜蜂的识别线索必须完全符合一个群体的模板，才能识别出它是一个群体的成员。我们发现，如果应用于保护蜜蜂的模板中的五种化合物中的任何一种在另一只蜜蜂身上缺失，那么保护蜜蜂就不太可能将其识别为群体成员。该化合物的部分缺失导致了群体成员的中低鉴定率。我们接下来假设保护蜜蜂评估它们模板中化合物的比例（比例假设）。或者，蜜蜂可能会独立评估每种化合物的浓度（浓度假设）。我们对比率和浓度假设的测试表明，模板的每个组成部分对区分都很重要。尽管这些数据并不能完全支持比率假说，但守卫蜜蜂评估了一只蜜蜂识别线索的浓度，并在其他线索的背景下至少部分地评估了它们。然后，这些信息被用来区分有巢的和没有巢的。(C) 2004动物行为研究协会。Elsevier Ltd.出版。版权所有。
We used nestmate recognition as a model system for testing how animals discriminate complex odour mixtures. Olfactory discrimination is important in social recognition in many animal species, yet the methods used by animals to interpret olfactory social signals are poorly understood. Our first hypothesis was that a guard honeybee would develop a new recognition template (the information used to discriminate nestmates from non-nestmates) when exposed to cue compounds. The data supported the conclusion that guard bees can adopt a new template. Our second hypothesis was that a bee's recognition cues must completely match a colony's template to identify that bee as a colony member. We found that if any one of five compounds in a template applied to a guard bee was absent on another bee, then the guard was unlikely to identify that bee as a colony member. Partial absence of the compound resulted in intermediate or low rates of colony-member identification. We next hypothesized that guard bees assess the ratios of compounds in their template (ratio hypothesis). Alternatively, bees might assess the concentration of each compound independently (concentration hypothesis). Our tests of the ratio and concentration hypotheses suggested that each component of the template is important for discrimination. Whereas the data did not fully support the ratio hypothesis, guard bees assessed the concentrations of an incoming bee's recognition cues and evaluated them, at least partially, in the context of other cues. This information was then used to make discriminations between nestmates and non-nestmates. (C) 2004 The Association for the Study of Animal Behaviour. Published by Elsevier Ltd. All rights reserved.
