> The present study demonstrates variability in the incidence and viral loads of the tested virus set across the queen's developmental stages. It is worth pointing out that all seven tested viruses were detected (pooled samples), with the highest incidence observed for BQCV, LSV3, DWV-B, and SBV at 72%, 69%, 60%, and 40%, respectively. ABPV, CBPV, and DWV-A were also detected but at relatively low levels. Furthermore, studies have suggested that these viruses may impact the health and productivity of queens . Regarding this issue, viruses can be transmitted vertically from queen mother through eggs to the offspring.

Comment: It would be great to know the levels of viruses our queens have. At some point, getting a report may be cost-effective. I believe it would be valuable in a breeding program.
