Incidence parasitaire d'opius concolor [Spzl] [Hymenoptera, braconidae] sur un hote de remplacement 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 polyacrylamid gel electrophoresis and immunoelectrophoresis methods. A noticeable modification of C. capitata proteins was observed when parasited by 0. concolor. But the most important phenomenon is the finding of common antigens obetween the host and the parasite. These results are discussed with regard to trophic and parasitic behaviour of the parasite
