Autostichidae
Systematic position: Autostichidae is a family of moths belonging to the order Lepidoptera. These insects are classified as small, often cryptic moths that play a significant role as pests in environments involving stored products and organic plant matter.

Autostichidae
Host crops: These moths primarily infest stored grain products, including wheat, barley, and maize, as well as various leguminous and industrial seeds. They are commonly found in warehouses, silos, and mills where they target cereal-based processed products like flour and animal feed mixtures.
Biology and lifecycle: The lifecycle of Autostichidae follows the typical holometabolous development process. Adult females lay eggs on or near the food source. The larval stage is the primary feeding phase, where caterpillars consume the stored product. After several molts, the larvae pupate within protective silken cocoons spun amidst the debris or damaged grain.
Damage and economic impact: Damage is characterized by larvae tunneling into seeds or webbing together product particles, leading to significant quality degradation. This infestation results in quantitative losses and severe reduction in the nutritional value of stored stocks, often rendering grain unsuitable for human consumption or seeding.
Control measures: Managing Autostichidae requires a focus on preventive sanitation. Recommended strategies include:
- Regular inspection of storage facilities to detect early infestation.
- Maintaining optimal grain moisture levels below critical thresholds (usually under 13-14%).
- Proper cleaning of equipment to remove organic residues.
- Application of specialized fumigants or cold storage techniques when infestation levels exceed economic thresholds.
