Capros

Capros (lat. Capros) is a genus of insects from the order Coleoptera, belonging to the weevil family (Curculionidae). In agricultural practice, this pest poses a significant threat to a range of fruit and ornamental crops, specifically adapting to the growth conditions of its host plants.

This pest primarily infests woody species and shrubs, damaging buds, young shoots, and foliage. The greatest damage is recorded in nurseries and young orchards, where the weakening of young plants leads to stunted development, loss of commercial quality, and potential death if not properly controlled by agronomists.

The biology of the pest is closely linked to seasonal temperature variations. The life cycle includes egg, larval, pupal, and adult stages. Adults typically emerge from diapause at the beginning of the growing season when buds begin to swell. Females lay eggs directly into plant tissues, making the early detection of adults a critical stage for effective crop protection.

The nature of the damage manifests as necrotic spots, leaf deformation, and bud drop. Economic impact is not limited to mechanical tissue damage but also involves the transmission of bacterial and viral pathogens, which can lead to epiphytotics across an entire plot or agricultural holding.

Protection measures involve a comprehensive approach, consisting of agrotechnical and chemical control methods. Key recommendations for management include:

• Maintaining crop rotation and spatial isolation of susceptible plants.
• Applying systemic insecticides during the early spring period.
• Sanitary pruning and destruction of infested branches before larval emergence.
• Using pheromone traps for population monitoring and timing interventions.
