>When more than one mite invade a single brood cell, the per capita fecundity decreases, as the number of mother mites per cell increases. Mites invading brood cells in older combs also have fewer offspring. This led scientists to speculate that mites themselves might have a chemical to inhibit each other’s reproduction (a pheromone).

These two statements are not mutually exclusive.  Old comb may be attracting mites more, but then reducing their fecundity.  It gets better!

I read a bit deeper into the paper and read it differently,  the number of mites was reduced in old comb,  but as I read it there was no change in the number of fertile mites?   Maybe I misread the numbers??


I know one beekeeper with  30 year old comb,  and all old stuff..... mites get him too.
