Jerboas (Dipodidae)
Jerboas (family Dipodidae) are saltatorial rodents adapted to arid and semi-arid environments. While they are fascinating biological specimens, in agricultural regions, their foraging habits can turn them into significant pests that threaten cereal grain production and other crops.

Jerboas (Dipodidae)
The primary crops affected by jerboas include wheat, barley, and other small grains, as well as melons and various vegetables. These rodents are opportunistic feeders and can cause noticeable damage during the growth and ripening stages of field crops.
In terms of biology and life cycle, jerboas are nocturnal creatures that dwell in deep burrows to escape extreme temperatures. They undergo seasonal periods of activity and hibernation. Their reproductive rate is influenced by environmental conditions, allowing populations to expand rapidly when food sources are abundant.
The damage caused by jerboas is characterized by grain consumption, stem cutting, and the destruction of seedlings. The economic impact is felt through reduced crop density and overall yield losses, particularly in regions bordering natural arid habitats where their populations are dense.
Management and protection strategies focus on preventive measures. Key practices include:
- deep tillage to disturb and collapse burrow systems;
- weed management around the field margins to reduce shelter;
- the application of rodenticides where populations exceed acceptable economic thresholds to minimize further field damage.
