Removal of optic lobes of adult blow flies ( Calliphora vicina) leaves photoperiodic induction of larval diapause intact

Blow flies ( Calliphora vicina) surgically deprived of their optic lobes were found to retain the ability to distinguish between short and long day lengths for the production of diapausing or nondiapausing larval progeny. In this species, therefore, the compound eyes and optic lobes are not essentia...

Summary:Blow flies ( Calliphora vicina) surgically deprived of their optic lobes were found to retain the ability to distinguish between short and long day lengths for the production of diapausing or nondiapausing larval progeny. In this species, therefore, the compound eyes and optic lobes are not essential for photoperiodic reception, and the optic lobes cannot be the site of the photoperiodic clock. The brain emerges as a likely location for both functions.
