Trogiid barklice
The family Trogiidae belongs to the order Psocoptera. Often referred to as booklice, these tiny insects are common pests in domestic and industrial environments, particularly in areas where humidity promotes the growth of mold and fungi on stored materials.

These pests cause significant damage to various products, including grain, seeds, flour, and processed animal feeds. Beyond agricultural storage, Trogiidae are notorious for damaging organic matter in archives, herbariums, and libraries, where they feed on glues, binding materials, and paper.
The biology of Trogiidae is characterized by simple metamorphosis. They thrive in damp, undisturbed environments, feeding primarily on microscopic fungi and organic debris. Their life cycle can proceed rapidly under warm and humid conditions, allowing populations to expand quickly if sanitation is neglected.
The nature of damage involves the consumption of seed germs and the degradation of organic packaging. Because they often thrive alongside mold, their presence is an indicator of poor storage conditions. They cause loss of product quality and can contaminate agricultural commodities with their excrement and body parts.
Effective management requires a combination of cultural and chemical strategies.
- Maintain low humidity levels (below 60%) to prevent mold growth.
- Ensure thorough cleaning of storage sites to remove debris.
- Use appropriate insecticides or fumigants as a last resort in cases of heavy infestation.
- Improve ventilation to minimize moisture accumulation.
