Stability of a Double Translocation Strain in Ceratitis capitata

Conference paper


Genetic sexing mechanisms represent important advantages for SIT programmes Therefore, one of the most important goals in the research related to this technique for the medfly has been to develop such a mechanism. At present the construction of genetic sexing systems are based on the induction of translocation that link the sexing character to the male chromosome (Rossler, 1979; Robinson and Van Heemert, 1982). The stability of these translocations is an important feature because if the linkage between the sexing trait and sex breaks down, the system no longer works. The breakdown can occur due to recombination or to the appearance of individuals coming from aneuploid gametes product of an adjacent segregation in meiosis (Saul, 1986). Here we present data on the stability of a double translocation used for genetic sexing.
