最近，蜜蜂群体损失的原因已被深入研究，表明有多个压力因素与群体下降有关，其中一个压力因素是暴露于农药。测量蜂箱中单个蜜蜂对杀虫剂的暴露至少与评估觅食蜜蜂对杀虫剂的潜在暴露一样困难。我们提出了一个模型，探讨如何异质性的农药分布在蜂巢中的梳子可以由工人的行为。该模型包含简化的行为，以捕捉可能的异质性的农药位置/沉积在蜂巢内的暴露水平进行比较，估计通过平均值在整个comb. When成人饲料花蜜含有的平均浓度的所有农药带入蜂巢在特定的一天，它可能是最坏情况下的暴露情况下的代表。然而，对于幼虫来说，在某些情况下，蜂巢中聚集的农药可能导致比平均浓度更高的暴露水平。外推模型的风险评估的潜力进行了讨论。
Recently, the causes of honeybee colony losses have been intensely studied, showing that there are multiple stressors implicated in colony declines, one stressor being the exposure to pesticides. Measuring exposure of individual bees within a hive to pesticide is at least as difficult as assessing the potential exposure of foraging bees to pesticide. We present a model to explore how heterogeneity of pesticide distribution on a comb in the hive can be driven by worker behaviors. The model contains simplified behaviors to capture the extremes of possible heterogeneity of pesticide location/deposition within the hive to compare with exposure levels estimated by averaging values across the comb. When adults feed on nectar containing the average concentration of all pesticide brought into the hive on that particular day, it is likely representative of the worst-case exposure scenario. However, for larvae, clustering of pesticide in the comb can lead to higher exposure levels than taking an average concentration in some circumstances. The potential for extrapolating the model to risk assessment is discussed.
