Mole-rat

The mole-rat (Spalax) belongs to the family Spalacidae and is a highly adapted subterranean rodent. Unlike burrowing moles, mole-rats use their strong, protruding incisors to dig elaborate tunnel systems, moving through the soil to reach tubers, roots, and bulbs, which form the base of their diet.

This pest is a significant threat to agricultural productivity, particularly for root crops like potatoes, carrots, and sugar beets. By consuming the underground parts of plants, they effectively kill young crops and ruin harvests. They often pull entire plants into their tunnels, leaving behind only the top leaves.

Regarding biology and life cycle, mole-rats are solitary and territorial animals. They reach sexual maturity slowly and have a low reproductive rate, with females giving birth to a small litter annually. Despite this, their ability to remain hidden makes them difficult to monitor until significant damage has already occurred.

Damage symptoms are primarily identified by large, irregular soil mounds on the surface. These mounds indicate the presence of a deep tunnel network. Farmers should monitor their fields for sudden plant wilting or disappearance, which typically points to the activity of these rodents moving beneath the rows.

Effective management strategies include the following methods:

• Using mechanical traps placed deep within the main tunnels.
• Installing sonic or ultrasonic vibration devices to deter them.
• Implementing deep plowing to disrupt tunnel integrity.
• Creating perimeter barriers with wire mesh or gravel.

Chemical control is rarely effective for mole-rats because they are elusive and live deep underground. Therefore, a combination of trapping and habitat modification remains the most recommended approach for preventing long-term damage to crops and infrastructure.
