[Characterization of vitellogenins and vitellines in Ceratatitis capitata (Diptera, Trypetidae): electrophoretic and immunoelectrophoretic study].
Electrophoretic study of haemolymphatic proteins in Ceratitis capitata has allowed to establish a proteic sexual dimorphism in this insect. This consists in a proteic fraction which is specific to the male and which appears at the imaginal ecdysis and stays during all the imaginal stage and in 3 other fractions which are characteristic to the female. Immuno electrophoretic study showed that these female proteins could be considered as vitellogenins. The nature and the mode of incorporation of those proteins in the oocyte are discussed.
