I'm hoping that someone who reads this thread will have tried this and will be able to provide useful feedback on how to optimize a strategy that I've been thinking about.
I've managed varroa in my apiary with organic acids (oxalic acid vaporization and formic acid strips), green drone comb placement (so that they can be removed, frozen, and eliminated), and hive splitting and requeening with queens raised from my best hives to introduce brood breaks that would hamper varroa reproduction.
This year I am going to be devoting significant effort to improving my apiary's genetic stock (queens of a few different lines ordered from a few different sources), and in addition to grafting larvae and raising queen cells from these queens, I want to pull frames of drone brood from my best hives and from these new queens in an effort to saturate my drone congregation area by selectively placing them into a few nucs at nearby outapiaries (instead of freezing them). I'd be using my older, less productive queens (ones that would otherwise have been given Michael Palmer's hive tool test) to serve as the queens in these nucs...they're really just being created to be overflowing with drones...
The number of drones raised this way will stack the deck favorably when the virgins take their mating flights and will hopefully result in improved local genetics overall with my bees having a greater ability to cope with varroa, make it through a New England winter, bring in the honey, etc.
I'm a little worried about creating mite bombs with these nucs that might ultimately hurt my apiary.
Does anyone have any thoughts or suggestions from personal experience in doing something like this? Are there any articles or chapters that you can suggest I read that might detail important steps/procedures to increase the probability of success?
