Lachesillid barklice
Lachesillidae is a family of tiny insects belonging to the order Psocoptera, commonly known as barklice or booklice. While they are not typically classified as primary pests of living crops, they represent a significant challenge in the storage and handling of agricultural commodities where high humidity facilitates their development.

Lachesillid barklice
Systematically, this family is part of the suborder Psocomorpha. They are characterized by their small size and specific wing venation. These insects are cryptic, often hiding in crevices, bark, or structural gaps, which makes their detection and control difficult without precise monitoring techniques.
The primary concern regarding Lachesillidae is their impact on stored products. They are not direct consumers of healthy seeds but thrive on the microscopic fungi and mold that grow on damp grain or agricultural produce. By feeding on these fungi, they contaminate stored stocks, leading to quality degradation and losses in market value.
Their life cycle involves egg, nymphal, and adult stages. They require high moisture levels for population outbreaks. Under optimal conditions, such as warm temperatures and elevated relative humidity in storage facilities, their reproductive cycle is rapid, allowing populations to expand quickly and spread throughout the stored material.
Effective management requires a strict focus on environmental control within storage facilities. Key protection measures include:
- Maintaining relative humidity levels below 60% to prevent fungal growth.
- Regular cleaning of storage areas to remove debris and potential food sources.
- Use of appropriate desiccant dusts or authorized fumigants when infestations are detected.
- Ensuring proper ventilation of bulk stored grain and seeds to reduce moisture pockets.
