Phylogenetic analysis, using the putative amino acid sequence of the conserved RNA-dependent RNA polymerase (RdRp) domain, indicated that HaNV clustered with Spodoptera exigua Nora virus, Drosophila Nora virus and Nasonia vitripennis virus-3 with a high bootstrap value (100%), which might indicate a new viral family within the order Picornavirales. HaNV was efficiently horizontally transmitted between hosts via contaminated food, and transmission was found to be dose-dependent (up to 100% efficiency with 109 viral copy number/µl). HaNV was also found to be transmitted vertically from parent to offspring, mainly through transovum transmission (virus contamination on the surface of the eggs), but having a lower transmission efficiency (around 43%). Infection distribution within the host was also investigated, with HaNV mainly found in only the gut of both adult moths and larvae (>90%). Moreover, our results showed that HaNV appears not to be an overtly pathogenic virus to its host.",
