Abstract: | Suitability ofDrosophila melanogaster larvae to their endoparasiteLeptopilina boulardi (Nordlander, 1980) shows wide genetic and epigenetic variation. Experiments were done onDrosophila isofemale lines. When reared in optimal laboratory conditions only 50 % of parasitizedDrosophila larvae gave rise to an adult wasp, and significant variation was observed between lines. In crowded conditions, this average value increased up to 90 % and no more significant variability could be detected between lines. Genetic and demographic consequences of these results are discussed. Associé au C.N.R.S. no 243 |
