Beautifully stated Jerry. It's all about the "r's"--the relative
intrinsic rates of increase for the two species. By my calcs, they are
roughly the same when there is ample brood present--both the mite and bee
populations will roughly double each month (in non resistant bees). Giving
either a slight edge makes all the difference in the world.
Your findings on brood thermoregulation are of great interest, and I hope
that you have time to publish them soon.
