Development of the Formal Genetics of the Mediterranean Fruitfly, Ceratitis Capitata Wied. Final Report for the Period 1 December 1976 - 29 February 1980

摘要

An attempt was made to develop Medfly (Ceratitis capitata) strains with a sex-limited dimorphism permitting automated sex-sorting through pupal colour dimorphism. (Such sorting is important in sterile insect release). This can be achieved by ''translocating'' mutant pupal colour alleles into the male's Y-chromosome. The Y-chromosome translocations were effected by irradiating wild-type males with 1.0-1.2 Krad of gamma radiation, followed by appropriate crossing. The results have been published in Entomophaga 24(1979)411-416). The effect of sterilization on fertility and competitiveness of males of the ''69-apricot'' line was investigated.
