Plaster beetle

Systematic position: The plaster beetle (Cartodere nodifer) belongs to the order Coleoptera and the family Latridiidae. These minute beetles are commonly known as mold beetles because their presence is strictly correlated with the growth of micro-fungi and mold in damp environments.

Host materials and infestation: These beetles do not feed on healthy plant tissues. Instead, they infest stored grain, seeds, dried herbs, tobacco, and processed food products that have become damp or moldy. They are frequently found in new buildings with high moisture levels, as well as in warehouses and storage facilities where ventilation is poor.

Biology and life cycle: The life cycle is dependent on the availability of fungal spores and mycelium. Cartodere nodifer thrives in conditions with high relative humidity and moderate to warm temperatures. Eggs are typically laid on surfaces covered with mold, which allows newly hatched larvae to begin feeding immediately upon emergence.

Damage and pest status: While they do not consume large amounts of physical material, their presence causes serious contamination issues. They degrade the quality of stored goods through their fecal matter and cast skins. In agricultural and commercial settings, their presence is considered a nuisance and a sign of improper sanitation and excessive moisture levels.

• Reducing ambient humidity levels to below 60% in storage.
• Improving air circulation to prevent mold growth.
• Removing all sources of mold and decaying organic material.
• Regular inspections of grain storage areas for moisture leaks.
• Applying desiccant materials to keep storage environments dry.
