Coffee berry borer

Systematic position: Hypothenemus solitarius is a member of the order Coleoptera, family Curculionidae, subfamily Scolytinae. This species is a highly specialized beetle known for its ability to inhabit and consume the internal tissues of plant fruits.

Host plants: The primary host plants for this species are various species within the genus Coffea. Due to its life cycle, it primarily targets the endosperm of the coffee bean, making it a significant challenge for coffee plantations in tropical climates globally.

Biology and lifecycle: The lifecycle of the beetle is contained almost entirely within the fruit. Adult females bore into the berry to lay eggs directly into the seed. The developing larvae feed on the endosperm, pupate inside the gallery, and emerge as adults to restart the cycle, often creating multiple generations within a single harvest season.

Damage and economic significance: The economic damage is caused by the larval feeding, which leads to seed destruction, reduction in coffee quality, and significant loss of yield. Infested berries are often discarded during the sorting process, which increases processing costs and lowers the overall market value of the harvested produce.

• Implementing strict sanitation programs to remove infested berries from the tree.
• Prompt collection and destruction of fallen berries (ground maintenance).
• Deployment of pheromone-based traps to monitor and trap adult populations.
• Application of selective insecticides during the peak of adult emergence.
• Continuous pruning to improve airflow and reduce the humidity favored by the beetles.
