Rose, an eye color mutation in a species of the Anastrepha fraterculus complex (Diptera : Tephritidae)

The rose eye color mutation is described in Anastrepha sp. l aff. fratercul us. It changes the color of the wild-type eyes from reddish with a blue-gre en iridescence to yellow-orange with a rosy iridescence. The wild-type and rose phenotypes are distinguishable in dried individuals at least 2-3 wk af ter death. Rose is transmitted as a recessive autosomal mutation. Disruptio n of the ommatidial pattern was observed as an alignment irregularity and e nlargement of some individual ommatidia. Mutant individuals have reduced fi tness relative to the wild-type. The rose mutation, the first one described in Anastrepha, has potential use in release-recapture studies and as a mar ker for mass-reared flies.
