Tribolium castaneum (Tcas5.2)

Tribolium castaneum Assembly and Gene Annotation

About Tribolium castaneum

The red flour beetle, Tribolium castaneum, is a common pest of stored agricultural products, and is also a genetic model for the Coleoptera. Tribolium castaneum can be found where grains or other dried foods are stored and has evolved a kidney-like organ to survive in such dry environments. It has demonstrated resistance to all classes of insecticides.
