title: [Parasitic effect of Opius concolor (Spzl) (Hymenoptera, Braconidae) on an intermediate host Ceratitis capitata Wied (Diptera, Trypetidae)].
abstract: The parasitic incidence of Opius concolor (Hymenoptera, Braconidae) on a replacement host, Ceratitis capitata (Diptera, Trypetidae) was studied using polyacrylamide gel electrophoresis and immunoelectrophoresis methods. A noticeable modification of C. capitata proteins was observed when parasited by O. concolor. But the most important phenomenon is the finding of common antigens between the host and the parasite. These results are discussed with regard to trophic and parasitic behaviour of the parasite.
