The Angoumois Moth, scientifically known as Sitotroga cerealella, is a small grayish-brown insect belonging to the family Gelechiidae. It is a widely distributed pest that primarily infests stored grain products, with a particular affinity for corn and other cereals. As a common and destructive grain moth, it is named after the Angoumois region in France, where it was first observed.
Characterized by a slender body, narrow wingspan, and intense powdery scales coating its wings, the Angoumois Moth typically measures about 7-11 mm in length. Its larvae, which are the primary culprits causing damage to stored grains, are small, whitish caterpillars with brown heads and grow to about 8-13 mm in length when fully developed. These voracious pests burrow into kernels, feeding on the nutritious contents and leaving behind a trail of frass.
Due to its resistance to cold temperatures, the Angoumois Moth can survive in various climates, thriving in all types of grain storage facilities, grain elevators, and even in home pantries. Infestation of crops can lead to significant economic losses by reducing grain quality, causing weight loss, promoting mold growth, and deteriorating overall marketability.
Control measures for Angoumois Moths typically involve strict sanitation practices, including regular monitoring, cleaning, and the use of effective insecticides or fumigants in affected storage areas. Prevention is key, and proper storage techniques, such as maintaining low moisture levels and frequent grain turnover, are crucial in deterring infestation and minimizing the potential damage caused by these destructive pests.
