Abstract
Pupae of Ceratitis capitata (Wiedemann, 1824) were irradiated with 60 Gy gamma radiation and subsequently the emergent males were crossed with females of recessive mutants on white pupa color (w p/w p). A strain with a translocation between autosomal chromosome number 5, carrier of w p+ dominant gene, and Y chromosome was isolated. By this way the T:Y (w p+) 70 strain with sexual dimorphism based on pupal color was obtained. Cytological examination of the males was carried out to confirm the translocation. The genetic stability was monitored under laboratory conditions during 21 generations. The rates of contaminant females emerged from brown pupae were 0,96 to 4,5% and for males from white pupae these rates were 0,26 to 0,66%. These values presented no definite increase tendency. The origin of contaminant genotypes and the potential for utilization of the sterile male techniques are discussed. (author).
