     Unfortunately, it is hard for me to get excited about this 
reference to the use of an antagonist to block germination sites on AFB 
spores. The free fatty acids, including Linoleic acid, do exactly the 
same thing and were explored for effectiveness here in Western Australia 
by a group of beekeepers some years ago. Results were very mixed and 
this approach was subsequently abandoned. The difficulty appears to be 
keeping the antagonist available to meet up with the spores ad 
infinitum, otherwise disease breakdown occurs. Once sporulation has 
occurred, the spores are distributed so widely,  there are so many of 
them, and their viability persists for so long, that it becomes 
inevitable that some will eventually find their way into the larval gut. 
Unfortunately it seems this approach doesn't appear to be within the 
realms of practicability. For both the bees and the beekeeper's sake I 
wish it were.

in Western Australia, where we are experiencing (so far) a relatively 
benign summer weather pattern. Our brethren on the east coast of Oz have 
however, not been quite so fortunate.
