研究发现，采食1 M糖源的蚂蚁比采食0.05 M或0.1 M糖源的蚂蚁多留下43%的痕迹。在个体采集过程中，每个觅食者铺路的次数减少，估计每个觅食者铺路信息素的平均寿命为47分钟。一个描述觅食者在两条路径中选择一条路径的概率的数学函数与路径上的信息素数量密切相关，与实验数据非常吻合。这些结果被纳入描述黑乳杆菌招募动态的模型。该模型的模拟表明，观察到的关于食物来源质量的路径铺设调制本身就足以说明实验中看到的更丰富的来源的系统选择。
Foragers of the ant Lasius niger exploiting a 1 M sugar source were found to lay 43 % more trail marks than those exploiting a 0.05 or a 0.1 M source. The trail laying per forager decreased during the course of individual recruitment episodes, and the mean lifetime of the trail pheromone was estimated to be 47 min. A mathematical function describing the probability that a forager chooses one of two paths in relation to the amount of trail pheromone on them closely fitted experimental data. These results were incorporated into a model describing the recruitment dynamics of L. niger. Simulations of this model showed that the observed modulation of trail laying with respect to food source quality is sufficient in itself to account for the systematic selection of the richer source seen in the experiments.
