Abstract
The wild-type allele of a “dark pupae” mutant of the Mediterranean fruitfly,Ceratitis capitata Wied. was translocated to the male's Y-chromosome. Through a series of crosses and backcrosses, 2 lines of the Mediterranean fruitfly with the male linked translocation were produced. These lines produced continuously wild-type (brown pupae) males and mutant “dark pupae” females. The lines are true-breeding. Automated sex-sorting of such lines may be feasible using the pupal color dimorphism.
Résumé
L'allèle du type sauvage d'un mutant «pupe noire» de la mouche méditerranéenne des fruits,Ceratitis capitata Wied. a été transféré sur le chromosome X du mâle. Par toute une série de croisements et de croisements réverses, 2 lignées de mouches ayant cette translocation liée au mâle ont été obtenues. Ces lignées produisent de façon continue des mâles du type sauvage (pupes brunes) et des femelles mutantes aux pupes noires. Ces lignées faciles à élever permettent la séparation des sexes d'après le dimorphisme dans la couleur des pupes.
