Artificial overwintering, assuming that adulthood is the overwintering stage, has been performed on six experimental populations of Drosophila melanogaster. In five of them, the frequency of flies infected by the hereditary Rhabdovirus sigma is always in the first spring generation than it was in the last generation of the preceding fall. This result might(More)

— In natural populations of Drosophila melanogaster throughout the world a minority of flies are infected by a rhabdovirus, sigma, which is not contagious but is transmitted through gametes. Transmission of the virus by males is a cornerstone for its maintenance in populations. The experiments reported in this paper show that in the wild European(More)
It has been shown previously that a polymorphism for two alleles of the ref(2)P locus is a regular feature of French natural populations of Drosophila melanogaster and that this is maintained in laboratory populations raised in cages. In this paper, an experimental population and egg-collection experiments are reported. Differential survival of the three(More)
