چکیده
A new Densonucleosis virus was isolated from the maize worm, Mythimna(= Leucania) loreyi Dup.,) in Egypt. This Virus may play an important role, as a regulating factor of pest populations. The virushas icosahedral non-enveloped particles of 25 nm in diameter. The Virionsof Mythinzno loreyi Densovirus (MCDNV) contained 4 structural proteins with molecular weights of 41 000, . 53000,63000 and 91000 daltons, respectively. The size of the DNA molecule which composes the viral genome was estimated to be 5950 bases. Southern hybridization and ELISA tests revealed a relationship between MCDNV and both Galleria mellonella DNV and Junonia coenia DNV, but failed to reveal any homology with Casphaliaextrunea DNV. Restriction profiles of the MfDNV DNA showed essential differences between M " V and GmDNV as well as with JcDNV. It is suggested that MlDNV is a member of the Densovirus genus (Parvoviridae family).
