Wood mouse

The wood mouse (lat. Apodemus sylvaticus) is a small rodent belonging to the order Rodentia and the family Muridae. It is recognized as a significant agricultural pest that inhabits both woodlands and arable lands, often causing severe damage to a wide variety of cultivated crops in agricultural ecosystems.

This species is highly destructive to cereal crops, including wheat and barley, consuming sown seeds and young seedlings in the early stages of development. In orchards, wood mice pose a significant threat by gnawing on the bark of young fruit trees, which can girdle the stems and lead to the death of the saplings. They also frequently damage vegetable crops and tubers in gardens.

The biology of the wood mouse is characterized by high reproductive rates, with females capable of producing several litters per year under favorable conditions. They are primarily nocturnal, living in elaborate burrow systems. Their ability to adapt to human-altered environments allows them to thrive in fields, making them a persistent challenge for farmers throughout the growing season.

Damage caused by wood mice is often widespread. They are known for selective feeding on high-energy plant parts, such as embryos of cereal grains. In addition to direct crop loss, these rodents can contaminate food stores with their droppings and carry various pathogens. When population densities are high, the damage can result in significant economic losses for agricultural businesses.

Effective management and control strategies include:

• Implementing deep autumn plowing to destroy nesting sites and reduce rodent cover.
• Maintaining field margins free of weeds to minimize nesting habitats.
• Using approved rodenticides as part of an integrated pest management (IPM) program.
• Protecting young tree trunks with physical barriers like wire mesh.
• Promoting natural predators, such as owls and raptors, to maintain ecological balance.
