Elephant shrews
Elephant shrews (Macroscelidae) are a group of small mammals known for their unique morphology, resembling a mix between a shrew and a kangaroo. Although they are not specialized agricultural pests in a narrow sense, their activity in fields within certain African regions can create specific challenges for farmers and growers.

Elephant shrews
Systematically, these animals belong to the order Macroscelidea, which comprises several distinct genera. Despite their non-aggressive appearance, high population densities near agricultural lands can lead to mechanical damage to young shoots and plant root systems during their constant foraging activities.
The biology of elephant shrews is characterized by high agility and complex social behaviors. They are primarily diurnal, building elaborate burrow systems or utilizing existing natural shelters. Their reproductive cycle is adapted to the warm season, allowing populations to recover quickly after periods of environmental stress.
The nature of plant damage is most often associated with burrowing directly beneath the root zone of young crops, causing wilting and death due to root exposure. Additionally, while hunting for insects—their primary food source—they may disturb the rhizosphere of vegetable crops and gourds, indirectly impacting plant health.
Protection measures against these animals in agronomy are primarily based on deterrent and exclusion strategies. Effective management practices include:
- Deploying ultrasonic rodent repellers in the field.
- Installing physical barriers like fine-mesh fencing around sensitive crop zones.
- Implementing strict crop rotation and regular weeding to minimize nesting sites.
- Encouraging natural predators, such as birds of prey, to hunt in the agricultural area.
