The common vole is one of the most damaging rodents in agriculture. A number of methods are used to suppress its numbers and limit damage. One option is growing crops that are not suitable for voles; this might limit their numbers and distribution. Through long-term monitoring of common voles throughout the Czech Republic, their abundance in eleven crop types (annual, biennial and perennial crops) was evaluated through active burrow counts. Reference crops were selected from perennials and biennials and annual crops were selected as potential repellents. The perennial crops were clover with alfalfa, which serve as the primary habitat for voles. These crops are where voles are found in their highest densities, and from which they spread to the surrounding crops during periods of high abundance. The biennial winter rape was selected because it provides favourable conditions for voles to overwinter and multiply rapidly in the spring. Compared to perennial crops and winter rape, significantly lower numbers of voles were found in onions, poppy seeds and maize. Additionally, fewer voles were also found in mustard compared to perennial crops. Onion and poppy were the only crops to show a significantly lower abundance of voles in comparison to wheat. The annual crops tested are unattractive to voles and due to the cultivation practices used, they do not even have enough weeds as food. As profitable crops they can be cultivated over sufficiently large areas to potentially prevent the spread of voles to surrounding crops, especially during outbreak years.

驱虫作物可以减少普通田鼠 （Microtus arvalis） 的数量以减少作物损害吗？


普通田鼠是农业中最具破坏性的啮齿动物之一。许多方法可用于抑制其数量并限制伤害。一种选择是种植不适合田鼠的作物;这可能会限制它们的数量和分布。通过对整个捷克共和国的普通田鼠进行长期监测，通过主动洞穴计数评估了它们在 11 种作物类型（一年生、两年生和多年生作物）中的丰度。参考作物是从多年生和二年生植物中选择的，一年生作物被选为潜在的驱虫剂。多年生作物是带有苜蓿的三叶草，是田鼠的主要栖息地。这些作物是田鼠密度最高的地方，在丰度高的时期，它们会从那里传播到周围的作物。选择两年一度的冬油菜是因为它为田鼠在春季越冬和快速繁殖提供了有利条件。与多年生作物和冬季油菜相比，在洋葱、罂粟种子和玉米中发现的田鼠数量明显较少。此外，与多年生作物相比，在芥菜中发现的田鼠也较少。与小麦相比，洋葱和罂粟是唯一显示出田鼠丰度显着较低的作物。测试的一年生作物对田鼠没有吸引力，而且由于使用的耕作方式，它们甚至没有足够的杂草作为食物。作为有利可图的作物，它们可以在足够大的面积上种植，以潜在地防止田鼠传播到周围的作物，尤其是在疫情爆发期间。
