13. Streptococcal L-forms isolated from Drosophila paulistorum semispecies cause sterility in male progeny.
The Drosophila paulistorum complex contains six semispecies that do not normally interbreed. In the laboratory, crosses between semispecies produce fertile daughters and sterile sons. Microbial endosymbionts have been observed in all D. paulistorum flies that display this male sterility. Streptococcal L-forms have been isolated from the Andean-Brazilian (Mes

19. Induction of Sterility in Drosophila paulistorum: Effect of Cytoplasmic Factors
Male hybrids from Mesitas and Santa Marta (Colombia) strains of Drosophila paulistorum are sterile. Homogenates of males belonging to these strains and from the hybrids were injected into Mesitas or Santa Marta females, which were crossed to males of their own strains, so that their progenies were genetically nonhybrid. Nevertheless, some of the males from t
