New report out

Nosema was highest in WA, HI, and CA; IAPV and KPV were much higher in CA; ABPV (Acute Bee Paralysis Virus) was highest in HI, WA, and CA. 

Of particular interest was a very sharp spike in N. ceranae levels in April and May this year. Deformed Wing Virus seems to be present at the same levels throughout the country.

California had much higher pathogen levels than most of the other states, so I can hardly imagine that one could make a case for keeping out of state bees out to protect California bees! The only pathogen that was lower in California than elsewhere was varroa, although Georgia also had low levels of varroa. 

Quoted from the report:

> The primary focus of this survey was to verify the absence of the parasitic mite Tropilaelaps and other exotic threats to the U.S. bee population (e.g., Apis cerana). Under current international trade agreements, the U.S. cannot deny import permits from other nations unless the exporting nation has a disease, parasite, or pest of honey bees that is not found in the U.S.
