Abstract: We report on a pearly eye mutant (PEM) line generated from a single male of Bactrocera cucurbitae collected in Kapoho, Hawaii. Crossing experi- ments with colony wild-type flies indicate that the locus controlling this trait is autosomal and the mutant allele is recessive. Experiments with females to assess response to visual oviposition cues (shape and color) suggest that PEM flies are at least unresponsive to color, and likely also unable to perceive visual shape cues. This phenotype has been described from field collection before, but its visual abili- ties have not previously been tested. The rediscovery of the PEM phenotype and results of the vision test support the hypothesis that the PEM trait has significant negative fitness consequences in the field, and that the recessive allele resulting in this phenotype probably occurs at a low frequency in nature.
