Description
Summary:is an ectoparasitic mite of Asian or Eastern honeybees which has become a serious threat to European subspecies of Western honeybees ( ) within the last century. and its vectored honeybee viruses became serious threats for colony survival. This is a short period for pathogen- and host-populations to adapt. To look for possible variation in the composition of viral populations we performed RNA metagenomic analysis of the Western honeybee subspecies , , , and and their respective mites. The analysis revealed two novel viruses: Varroa orthomyxovirus-1 (VOV-1) in and and a Hubei like-virga virus-14 homolog in . VOV-1 was more prevalent in than in and we found evidence for viral replication in both hosts. Interestingly, we found differences in viral loads of and their , , and its showed partial similarity, while and and their varroa where very similar. Deformed wing virus exhibited 82.20%, 99.20%, 97.90%, and 0.76% of total viral reads in , , , and respectively. This is the first report of a complete segmented-single-stranded negative-sense RNA virus genome in honeybees and mites.
