Tropical coffee berry borer

Hypothenemus crudiae is a species of beetle belonging to the order Coleoptera and the family Curculionidae (subfamily Scolytinae). It is a highly significant agricultural pest known for targeting the fruits and seeds of various tropical plants, primarily in equatorial regions.

The host range of this insect includes coffee berries, various legumes, and diverse tropical nuts. Its ability to thrive in warm, humid climates allows it to establish permanent populations on plantations, often leading to severe economic losses if not managed with precise agricultural interventions.

The life cycle is distinctively associated with the host fruit. An adult female bore into the fruit to lay her eggs, ensuring that the offspring have immediate access to food. The entire larval and pupal development occurs inside the seed, which protects the insect from environmental factors and most chemical applications.

Damage caused by this borer involves the systematic destruction of the seed interior. Infested berries often drop prematurely from the plant, and the remaining seeds show characteristic boreholes. These entry points significantly facilitate secondary contamination by molds and fungi, rendering the crop unmarketable.

• Strict sanitation practices, such as clearing all dropped berries from the field.
• Deployment of pheromone-based trapping systems for population monitoring.
• Application of biological control agents, specifically entomopathogenic fungi.
• Targeted use of systemic insecticides during the peak flight season.
• Post-harvest processing and sorting to identify and remove infested batches.
