通过估计或模拟昆虫授粉作物基因流模型中的参数，预测了熊蜂在红三叶草田间的花粉介导的基因流。一般来说，预测水平的基因流被发现依赖于访问蜜蜂的种类和红三叶草领域的空间布局。当田地彼此靠近时，基因流动主要取决于来访蜂种的典型觅食距离，但当田地相距较远时，红三叶草田地之间的基因流动对红三叶草田地之间的距离比对红三叶草田地之间的距离更敏感。给田地授粉的实际大黄蜂物种。使用建议的方法，基因流可以预测在不同的农业情景。例如，如果红三叶草田之间的基因流是由熊蜂介导的，并且假设红三叶草田是边长为100 m的正方形，红三叶草田之间相隔200 m，则预测中值基因流为0.17%。
Pollen-mediated gene flow between red clover fields by bumblebees is predicted by estimating or simulating the parameters in a gene flow model for insect-pollinated crops. Generally, the predicted level of gene flow was found to depend on the visiting bee species and the spatial arrangement of the red clover fields. When the fields are close to each other, the gene flow depends mainly on the typical foraging distance of the visiting bee species, but when the fields are far apart, the gene flow between red clover fields is more sensitive to the distances between red clover fields than to the actual bumblebee species that pollinates the fields. Using the suggested methodology, the gene flow may be predicted in different agricultural scenarios. For example, if the gene flow between red clover fields is mediated by Bombus terrestris and the red clover fields that were assumed to be quadrates with sides of 100 m are separated by 200 m, then the median gene flow is predicted to be 0.17%.
