Sitotroga cerealella
Angoumois grain moth
Sitotroga cerealella, the Angoumois grain moth, is a gelechiid moth and the type species of its genus. It is a significant pest of stored cereal grains, particularly wheat and corn. The species serves as a factitious host for mass rearing of the parasitoid Trichogramma chilonis in biological control programs. Laboratory studies indicate sensitivity to gamma irradiation and thermal stress, with dose-dependent effects on egg viability and adult longevity.
