Rough hide beetle

The rough hide beetle (lat. Trox scaber) belongs to the family Trogidae, order Coleoptera. Known primarily as scavengers that feed on dry animal matter, these beetles are often overlooked in agricultural settings until their population reaches levels that threaten the integrity of storage facilities and stored feed supplies.

This pest is commonly found in grain silos, poultry houses, and facilities processing animal-based agricultural products. While it does not directly consume live plants, its presence is highly detrimental to stored goods containing proteins or fats. Furthermore, the beetles have a habit of boring into wood and packaging materials, causing structural damage within warehouses.

The biology of Trox scaber is well-adapted to environments with low humidity and high availability of dry organic matter. The life cycle consists of egg, larva, pupa, and adult stages. Both larvae and adults are highly resilient, allowing the species to persist in neglected corners of buildings where dust and debris accumulate over long periods of time.

In terms of harmfulness, the rough hide beetle acts as a contaminant. By feeding on organic waste and tunneling through materials, they spread pathogens and create an environment that encourages the growth of mold and secondary pests. This degrades the nutritional quality of stored feeds and necessitates strict sanitary interventions to ensure animal health and facility safety.

Effective management strategies include the following:

• Rigorous warehouse sanitation to eliminate accumulations of organic dust and debris.
• Structural sealing of storage areas to prevent access to hidden nesting sites.
• Regular inspection of wooden beams and storage pallets for signs of tunneling.
• Application of approved residual insecticides in cracks and crevices during downtime.
