This study investigates the impact of the common vole on cereal crops adjacent to winter rape in a rodent outbreak year. Significant damage was found at the margins of adjacent cereal fields, indicating direct colonisation by voles from the winter rape fields. The damage gradually decreased towards the centre of the fields. We suppose that the reduction of winter rape quality as food connected with plant phenophase (ripening phase) resulted in spill-over of the voles to an adjacent crops. We also observed that spring barley crops were damaged more than winter wheat. We assume that this happened due to the fact that there was no barrier between fields of spring barley and winter rape, while wheat and rape fields were separated by a road. The number of voles at the barley field margin was significantly lower than in the middle (significantly in barley, non-significantly in wheat), which may be related to the depletion of resources at the margins. The abundance of voles appearing in rape was significantly lower than in cereals; in its ripening phase winter rape has low habitat value for voles. This study indicates that voles can cause the same amount of damage to cereals adjacent to winter rape as to cereals adjacent to their primary habitats (e.g. grassland). This is especially evident in years of vole outbreak.

这项研究调查了鼠害暴发年份普通田鼠对邻近冬季油菜的谷类作物的影响。在邻近谷物田的边缘发现了严重破坏，表明冬季油菜田的田鼠直接定居。损害逐渐向田间中心减小。我们认为，由于冬季油菜品质下降，与植物表型期（成熟期）有关的食物导致田鼠溢出到相邻作物上。我们还观察到，春季大麦作物受到的损害要大于冬季小麦。我们认为发生这种情况的原因是，春季大麦和冬季油菜田之间没有障碍，而小麦和油菜田之间却被道路隔开。大麦田边缘的田鼠数量明显低于中部（大麦中的田鼠，小麦中的田鼠不多），这可能与边缘的资源枯竭有关。强奸中出现的田鼠数量明显低于谷物中。在成熟期，冬季强奸的田鼠价值较低。这项研究表明，田鼠对临近冬季油菜的谷物造成的危害与对主要生境（例如草原）相邻的谷物造成的危害相同。这在田鼠爆发多年中尤为明显。这项研究表明，田鼠对临近冬季油菜的谷物造成的危害与对主要生境（例如草原）相邻的谷物造成的危害相同。这在田鼠爆发多年中尤为明显。这项研究表明，田鼠对临近冬季油菜的谷物造成的危害与对主要生境（例如草原）相邻的谷物造成的危害相同。这在田鼠爆发多年中尤为明显。
