[Iclusion proteins and viral proteins of the baculovirus of the dipteran Tipula paludosa (Meigen)].

Examination of the polyhedron protein by polyacrylamide gel electrophoresis shows only one polypeptide with a molecular weight of 25,500 +/- 500 daltons, while that of virion proteins reveals 13 polypeptides. No antigenic community could be demonstrated between the polyhedron protein of the Baculovirus of T. paludosa and the polyhedron protein of several other Baculoviruses.
