Hi all,

In case this is helpful, here is a review we recently wrote about
overwintering in honey bees!

http://ento.psu.edu/pollinators/publications/overwintering-honey-bees-biology-and-management

We developed a theory that changes in environmental nutritional resources
alter levels of pheromones in honey bee colonies, and this is what triggers
the production of overwintering bees - the student (Mali Doke) on this
project is currently testing that theory, so hopefully we will have more
info on that in a few months!

Happy New Year!

Christina
