A new Densovirus isolated from the African cotton bollworm Helicoverpa armigera Hbn. (Lepidoptera: Noctuidae) in Egypt [electronic resource].

For studying the genomic diversity of the Egyptian Densovirus isolatedfrom Mythimna loreyi (MIDNV), the epidemiological survey was done on the noctuid fauna of the lucerne alfalfa Medicago sativa on which the pests are the same that attack the cotton fields. During this work, we have isolated at EI-Bahareya Oasis from dead larvae of the African Cotton Bollworm Helicoverpa armigera another 25 nm icosahedral non-enveloped DNA virus sharing the main biological and biophysical properties of densovirus that we named HaDNV. After characterization and partial cloning of the genome, the presence of antigenic cross-reactivity and some sequence homology indicates that HaDNV and MIDNV are not phylogenetically distant. The 6 kb genome of HaDNV was found to have high homology with members of the Densovirus genus as Galleria mellonella DNV, Junonia coenia DNVand MIDNV.
