The varroa may infect a colony during some time even years, until in
a moment, may be in winter de colony collapses.
Somebody knows what is the way the colony collapses?
I suppose varroa has a great preference over drones' larvae, and
they get infected reason why they are not born in normal conditions.
If drones aren't normal, may be queens have problems for mating or
get fertilized eggs.
I would like to hear some explanations about the fact of collapse
and its causes.
Any comments will be appreciated.
