Jim,
Referring to your reasonings for comb rotation.

Presuming that your levels of AFB presence are correct, you suggest that rotation will in your case
have a 1 in 5 chance of removing an "infected frame" in any one year.

Do you not agree that a bee colony from which you would have removed the potentially contaminated
frame would also after removal of said frame still contain 9 other potentially spore contaminated
frames!

i.e. what benefit would be derived by the removal of only one frame from a AFB contaminated colony?

Sequential frame removal would only be useful if AFB took 5 years to reach a level that resulted in
detrimental consequences on the population. Plus, if the removal of frames was undertaken
sequentially as frame contamination took place.

If you agree that this not to be the case - then surely random removal of frames from an AFB
infected colony will have equivalent consequences and potential benefits as those of sequential
frame removal.

Hence that practice of removing all frames etc. from an "infected colony" and only replacing them
once the hive body et al. has been well toasted with an efficient flame throwing like device.

Regards,
Peter
