A rodent with a body length between 12 and 24 centimetres, widespread throughout Central Europe (also water vole, minor mouse, dry rat, earth rat). The field mouse also belongs to this family, although it plays no role in viticulture. The vole lives underground in corridors up to one meter deep in meadows, gardens and farmland. It also gnaws on the roots and rootstock of vines, which leads to poor budding, sudden wilting of leaves and even death. The population density is very high, so the damage can be considerable. The pest is controlled by traps or by creating colonisation sites for natural enemies such as weasels and other small mammals. See also under vine enemies.
