A model of food recruitment by social insects accounting for the competition between trails in the presence of an arbitrary number of sources is developed and analysed in detail. Both the case of identical environmental characteristics and the case where one source and the corresponding trail are different from the others are considered. Different collective responses depending on the environmental conditions, and without change of individual behaviour, are shown to exist, associated with the possibility that the colony may be led to exploit one source or a group of sources preferentially. The full bifurcation diagram of steady-state solutions is constructed from which the dominant exploitation patterns are identified. The biological relevance of the results is discussed and suggestions are made for their experimental testing in connection with the recruitment behavior of species using trail recruitment. The same phenomenological model can be used for different trail-laying species since the predictions are generic and not restricted to a given species, except for the parameter values used.

本文详细开发并分析了一个社会昆虫食物招募模型，该模型考虑了在存在任意数量食物源的情况下路径之间的竞争。我们考虑了环境特征相同的情况以及一个食物源和相应路径与其他食物源和路径不同的情况。结果表明，在不改变个体行为的情况下，根据环境条件会出现不同的集体反应，这与蚁群可能被引导优先利用一个食物源或一组食物源的可能性有关。构建了稳态解的完整分岔图，从中确定了主要的利用模式。讨论了结果的生物学相关性，并针对与使用路径招募的物种的招募行为相关的实验测试提出了建议。由于预测具有普遍性，除了所使用的参数值外，不限于特定物种，因此相同的现象学模型可用于不同的路径铺设物种。版权所有1999年学术出版社。
