FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
Light suppresses a rhythmic (approximately 0.3Hz) movement of the proboscis and antenna that is prominent in the mutants, and in white eyed derivative of the mutants, light enhances the climbing defect induced by general anaesthetic.
