Abstract: The present invention relates to a vector including: (i) an inverted terminal repeat (ITR) nucleotide sequence at the 5? position; (ii) a nucleotide sequence functionally bonded to a promoter at the central position, said nucleotide sequence coding for a toxin; and (iii) an inverted terminal repeat (ITR) nucleotide sequence at the 3? position, wherein said vector does not include any viral nucleotide sequences of Junonia coenia densovirus other than the ITR sequences according to (i) and (iii). The present invention also relates to a method for producing recombinant and nonreplicative particles of Junonia coenia densovirus (JcDNV) using such a vector. Finally, the present invention relates to the use of recombinant and nonreplicative particles of Junonia coenia densovirus produced according to the above-described method as a moth-control agent.

Abstract: Recombinant plasmids capable of replicating themselves in Escherichia coli containing a complete or partial sequence of the double or single strand DNA or a Densovirus causing a densovirosis in a sensitive insect, a process for obtaining said plasmids and a method of combatting ravager insects.
