White-shouldered house moth

The white-shouldered house moth (Endrosis sarcitrella) belongs to the order Lepidoptera and the family Oecophoridae. This species is a widespread cosmopolitan pest, commonly found in domestic and agricultural settings, including warehouses, granaries, and poultry houses, where it finds suitable conditions for larval development.

The moth is a scavenger that feeds on a wide range of organic materials. Its preferred agricultural targets include stored grain, dried legumes, flour, cereals, and plant debris. It thrives in neglected corners of storage facilities where moisture and organic refuse accumulate, providing an ideal microhabitat for the larvae.

The life cycle consists of the egg, larval, pupal, and adult stages. Females lay eggs on or near the food source. The larvae are robust and capable of surviving in varied environments, although their development speed is highly dependent on ambient temperature and relative humidity within the storage facility.

Larvae cause damage by boring into seeds and grains, consuming the endosperm, and webbing the surrounding material with silk. This activity not only causes direct weight loss but also ruins the quality and germination potential of seeds, leading to severe economic impacts for farmers and grain storage operators.

Control measures emphasize hygiene and environmental management:

• Maintaining strict sanitation protocols to remove dust and spilled grain.
• Ensuring grain is stored at moisture levels below 12% to inhibit larval survival.
• Regular inspection and cleaning of storage equipment and ventilation systems.
• Applying professional fumigation when heavy infestations are detected.
• Sealing storage containers to prevent the entry of egg-laying moths.
