Deformed wing virus prevalence in solitary bees put to the test: an experimental transmission study

Virus spillover from managed to unmanaged bees and vice versa may be one mechanism driving colony losses of the former declines latter. There is clear evidence that ubiquitous Deformed wing virus (DWV) a major driver honey bee ( Apis mellifera ) mortality. Although DWV has been detected in solitary Osmia bicornis , data on infectivity virulence are scarce. Here, we used microinjection investigate whether genotype A (DWV-A) obtained can replicate O. . DWV-A titers intermediate strand analyses suggest does not thus probably infectious for this species. Interestingly, demonstrate recovered 16 days post-microinjection remains A. Therefore, despite lack apparent species, potential act as host contribute increased populations other or
