Metamorphic development of the olfactory system in the red flour beetle (Tribolium castaneum, HERBST).

Background: Insects depend on their olfactory sense as a vital system. Olfactory cues are processed by a rather complex system and translated into various types of behavior. In holometabolous insects like the red flour beetle Tribolium castaneum, the nervous system typically undergoes considerable remodeling during metamorphosis.
