Thaneroclerus buqueti

Thaneroclerus buqueti is a beetle species belonging to the order Coleoptera and the family Cleridae. While many members of this family are known predators, this specific species is a significant pest of stored products. Originating from tropical climates, it is frequently intercepted in international trade, making it a subject of concern for agricultural quarantine services worldwide.

The pest primarily targets dry plant-based commodities. Its host range is extensive, including items such as cocoa beans, spices, nuts, dried fruits, and various stored grains. It thrives in warehouse environments where there is an accumulation of organic matter, providing both food and shelter for the entire development cycle of the beetle.

The life cycle of Thaneroclerus buqueti is temperature-dependent. Females lay eggs directly onto the food source or in nearby crevices. Upon hatching, the larvae begin to feed, creating tunnels and damaging the structure of the product. The transition through larval instars to the pupal stage occurs within the commodity, making them difficult to detect until substantial damage has already occurred.

The damage caused by this pest is twofold: direct consumption and contamination. Larvae and adults destroy the physical integrity of seeds and processed goods, leading to weight loss and degradation. Furthermore, their waste products, larval skins, and webbing contaminate the stocks, often rendering large batches of agricultural goods unfit for human consumption.

Effective management strategies include the following steps:

• Stringent sanitation practices to remove debris and residual stock.
• Implementation of warehouse climate control to lower temperature and humidity.
• Use of pheromone or sticky traps to monitor and reduce adult populations.
• Application of specialized fumigation protocols for heavily infested commodities.
