Abstract
An autosomal, recessive eye color mutant, rosy (ry), is described in the Mediterranean fruit fly, Ceratitis capitata (Wiedemann). The homozygous rosy flies are killed or delayed in development by the presence of purine in the larval rearing medium at levels that have little effect on wild-type flies. A possible genetic sexing technique is outlined that uses male flies which contain a Y chromosome-autosome translocation and are heterozygous for rosy and female flies which are homozygous for rosy. The development of female flies would be prevented when the stock is reared on purine-containing medium.
