Man, where was I when this thread started? The gun (not the smoking gun) we have right now is the IAPV, Israeli Acute Paralysis Virus. The newest development is that a hive in a green house was inoculated with it and crashed, but we are still waiting to see the final numbers etc. What we think most is that it is a combination of this and many other instances. The mite is the big problem, that was mentioned before. We have beekeepers who aren't treating their hives correctly, and we are getting serious resistance to it. I just was in Florida looking at bees, and we haven't heard much about CCD from them either right now. The bee block is for a mason bee and a blue orchard bee.
