The findings provide an important five-year baseline against which to track future trends. Key findings show that the varroa mite, a major honey bee pest, is far more abundant than previous estimates indicated and is closely linked to several damaging viruses. Also, the results show that the previously rare Chronic Bee Paralysis Virus has skyrocketed in prevalence since it was first detected by the survey in 2010.
The good news, however, is that three potentially damaging exotic species have not yet been introduced into the United States: the parasitic tropilaelaps mite, the Asian honey bee Apis cerana and slow bee paralysis virus.
