Coffee berry borer

Hypothenemus ruficeps is a beetle species belonging to the Curculionidae family, specifically the subfamily Scolytinae. As a member of the Scolytinae, it is closely related to the well-known coffee berry borer group, acting as a specialized pest that impacts tropical agricultural systems.

The primary host plants for this species are members of the genus Coffea. The beetle specifically targets coffee cherries, boring into the fruit to establish its breeding grounds within the endosperm of the coffee bean, which constitutes the most economically valuable part of the plant.

The biology of Hypothenemus ruficeps is centered on the coffee fruit. The female beetle penetrates the cherry, creating intricate galleries where she deposits her eggs. The larval stages feed directly on the bean tissue. Once development is complete, the new generation of adults may emerge to colonize neighboring berries, facilitating a rapid population increase.

Damage caused by this pest is significant. The physical destruction of the coffee bean leads to weight loss, lower market grade, and substantial economic losses for farmers. Furthermore, the boreholes serve as entry points for pathogens and fungi, which can degrade the quality of the harvested crop even further.

Integrated Pest Management (IPM) is essential for controlling this beetle. Growers must prioritize orchard hygiene to break the pest's life cycle.

• Systematic removal of infested and fallen berries.
• Use of ethanol-based traps for monitoring and mass trapping.
• Application of microbial control agents like Beauveria bassiana.
• Maintaining optimal orchard management practices to reduce host availability.
