Effective sanitation practices mitigate coffee berry borer, Hypothenemus hampei (Ferrari, 1867) (Coleoptera, Curculionidae) infestation in robusta coffee in Indonesia

Abstract

The coffee berry borer, Hypothenemus hampei (Ferrari, 1867), is a major pest responsible for substantial economic losses in global coffee production. This study investigated the impact of field management, particularly sanitation practices, on controlling H. hampei infestations in robusta coffee (Coffea canephora). Field observations were conducted in both maintained and non-maintained plantations to assess pest populations at different fruit development stages. Results showed that well-maintained fields had significantly lower pest populations across all developmental stages compared to non-maintained fields. Statistical analysis confirmed the effectiveness of sanitation measures in disrupting the pest’s life cycle. Mature cherries were found to be highly susceptible to infestation, emphasizing the importance of timely field management. Additionally, healthy coffee plants in managed fields showed greater resilience to pest attacks. The research underscores the vital role of consistent field management in mitigating pest damage and enhancing the sustainability of coffee production systems.
