NOt to start a conspiracy theory, but a friend of mine, close to the group put, in charge of finding a way to rid us of the killer bees, told me that there was a release of experimental parasites that target honey bees. Apparently, from what he said, they will attach to the bees and actually eat them from the inside out. But the downside is they will also destroy any domestic honey bees. I've noticed the honey bee numbers have dropped drastically, in Texas, since the late 1990's.
I don't know how accurate the information is that I was told, but I didn't see any reason for him to make up something like this. And I wouldn't put it past the gvt. to do this without informing the general public.
