Trogid beetles
The Trogidae family, commonly known as hide beetles or skin beetles, belongs to the order Coleoptera. These insects are primarily scavengers and keratophages, meaning they feed on keratin-rich materials. While not traditional plant pests, their presence in agricultural environments is often associated with poor sanitation and the presence of organic debris.

Trogid beetles
The biological cycle of Trogidae involves a complete metamorphosis. Larvae are typically found in dry, decaying organic matter, such as bird nests or animal remains. Understanding their lifecycle is crucial for agricultural professionals, as these beetles can thrive in neglected storage areas, moving from animal-based waste to stored agricultural products.
The damage caused by these beetles is primarily indirect but significant for quality control. They can infest grain stores if the product contains impurities or organic residues. By damaging packaging and contaminating stored goods with their excreta and larvae remnants, they degrade the overall quality of the agricultural product.
Protection measures should focus on integrated pest management (IPM) practices. The most effective strategy is the removal of potential breeding sites, such as animal carcasses, feathers, and old hides near warehouses. Keeping storage facilities dry and clean significantly reduces the risk of a Trogidae infestation.
Chemical control is rarely the first line of defense; however, if infestation levels are high, targeted applications of insecticides in storage units may be necessary. Monitoring through regular inspection and the use of traps is essential to detect early signs of beetle activity before they impact the commercial value of the stored crops.
