Sitotroga
Heinemann, 1870
Sitotroga is a of small in the , with five recognized . The genus is best known for , commonly called the , a significant stored-product pest of cereal grains. Species in this genus are routinely mass-reared in laboratory and insectary settings as for used in programs, particularly Trichogramma chilonis.

Habitat
Stored grain products; specifically documented in shelled corn and wheat grain systems. Mass rearing occurs in laboratory environments using tin chambers or glass jars with wheat grains as substrate.
Distribution
Distribution records from GBIF indicate presence in Norway (NO) and Sweden (SE). Natural distribution is poorly documented; are in association with stored grain products through human commerce.
Host Associations
- Trichogramma chilonis - relationship; S. cerealella are mass-reared to produce this egg for programs
- Pteromalus cerealellae - Documented of S. cerealella in shelled corn systems
Life Cycle
stage duration has been observed at 12 and 24 hours post- under laboratory conditions. of 7.06 days recorded for eggs exposed to 35 Gy irradiation. Pupal stage documented with of 86.66% at 5 Gy irradiation. Natural parameters not established from available sources.
Ecological Role
in stored grain . Serves as for mass-rearing of agents, enabling year-round availability of for research and field release programs.
Human Relevance
Economic pest of stored cereal grains, particularly corn and wheat. Subject to control efforts including using and evaluation of . Used extensively in insectary production systems to support biological control industry.
More Details
Mass rearing methodology
Mass rearing in newly designed tin chambers with 6 kg wheat grains achieved 21% higher production compared to traditional glass jar rearing, yielding up to 77.9 g of eggs sufficient for 1756 Trichogramma cards
Radiation sensitivity
show dose-dependent response to irradiation: 35 Gy resulted in 55.3% hatching rate and prolonged incubation, while 95 Gy caused lowest values for incubation, , and longevity
