This is a question for anyone on the list. Just to give you a little background as to why I ask. I have been doing the drone culling method for varroa this season and have a little knowledge of ethnic diets, thanks to the apitherapy course, it occured to me there may be a market for drone brood. I have found this to be quite lucrative, how about that, cashing in on mite control? I would like to refine my marketing a little and would like to have an idea of what kind of brood development extension I can expect at lower temperatures and still keep the brood alive. This is, I feel, an important aspect of my marketing after harvest. All I have ever read is lower temperatures extends development. I also have a concern as to what are the air requirements to keep these critters alive? As an aside for anyone curious, I am a medium frame/super beekeeper, I place two empty frames in the top brood box of each hive and make (attempt) my yard rounds on a 20 day basis. At this time I cut out any developing drone (eggs thru pupa) and keep only the capped brood for market, the remainder goes to my friends chickens or pigs gratis. 1 frame of brood cut in two fits nicely it a one gal. Ziploc bag, thus the air requirement concern. Presently I use a paper punch for one hole near the zipper. I could leave it open but often there is a limited amount of uncured nectar or honey that could leak out when stored flat. I have pretty much concluded the best way to store is vertical and open, basically solving metabolic heat buildup and the other two issues. Any and all comments will be appreciated.
