Mediterranean pine vole

The Mediterranean pine vole (Microtus duodecimcostatus) belongs to the order Rodentia and the family Cricetidae. It is a subterranean species known for its highly specialized life cycle in the Mediterranean climate, where it remains active in underground tunnel systems throughout the year.

This pest poses a serious threat to various agricultural crops. It causes significant damage to root crops such as sugar beets, carrots, and potatoes, as well as young trees in orchards by gnawing on their root systems. Such damage often results in the immediate death of the affected plant or long-term growth inhibition.

The biology of this species is defined by high reproductive rates and continuous breeding cycles. Their ability to remain underground for most of their lives makes them difficult to observe. Their burrowing activities facilitate the colonization of agricultural lands, where they find an abundant food supply throughout the growing season.

The damage is characterized by the systematic destruction of plant roots. Since the surface of the field often shows little evidence of activity until the plants start to wilt, the population density of the voles can reach critical levels before the farmer notices the infestation. This hidden nature of the damage makes them highly destructive.

Control strategies for the Mediterranean pine vole involve a mix of physical and chemical methods. Key practices include:

• Deep tillage to disrupt underground nest structures.
• Monitoring tunnel activity to identify high-density areas.
• Strategic placement of agricultural rodenticides.
• Maintaining field hygiene to reduce food availability.
