African striped grass mouse

The African striped grass mouse (Lemniscomys barbarus) is a member of the order Rodentia and the family Muridae. This species is widely distributed across northern Africa, often establishing itself as a significant agricultural pest in arable lands where its feeding habits can lead to substantial losses in agricultural productivity.

Morphologically, this rodent is easily recognized by the dark longitudinal stripe running along its dorsal side, which aids in camouflage within grasslands. These mice are primarily diurnal, meaning they forage during the day, which exposes them to predators but allows them to utilize daylight to locate food sources effectively within cultivated fields.

The diet of the African striped grass mouse is diverse, allowing it to exploit various plant stages. Its pest activity primarily affects the following:

• Cereal crops such as wheat, barley, and millet.
• Leguminous crops and vegetable seeds.
• Young seedlings in nurseries and fields.
• Wild grasses and mature grains during the pre-harvest phase.

The damage caused by this rodent is multifaceted: they consume sown seeds, severing young stems at the base, and feed on developing grain heads. This feeding behavior not only results in direct yield loss but also creates gaps in crop density, which can negatively impact the overall crop canopy and facilitate the growth of competing weeds.

Management strategies for this pest should focus on cultural and chemical control. Key practices include maintaining weed-free field borders to eliminate cover, conducting deep tillage to destroy nesting sites, and ensuring clean harvest operations to minimize residual food. When population thresholds are exceeded, the strategic use of approved rodenticides is necessary, provided they are applied to minimize environmental impact and protect non-target species.
