I must correct a mistake in my last posting. It was Israeli Acute 
Paralysis Virus (IAPV) of bees, not nosema ceranae, that people thought 
had been introduced by Australian package bees. The rest of my post is, 
I hope, accurate.  IAPV, it turns out, also predated the introduction of 
Australian package bees.
