Actually the folks at the LSU Louisiana Bee Lab did not really want to engage in a conversation about small cell beekeeping, after I mentioned the subject at last year's Louisiana beekeeper's meeting.
They are aware of Dee Lusby but would not say much about her and her small cell ideas either.
I don't see these folks often but I will encounter them in the future, I'm sure, and I will pump them further on the small cell subject.
The Louisiana Bee Lab does, I think, have a good reputation for their bee research efforts. However I also think that since scientific reasearch on anything can go on for a long time and scientist must stick with their efforts in the direction they have chosen. Appearently, in the small cell case, that is not where they want to go. Also this is MY speculation on the small cell subject and what the bee lab does.
In the future I will probably develop a more familiar relationship with the Bee Lab guys and hopefully gather more insight.
Further since comb can, and, does last for years, the build up of pupae residue/shells accumulates in the cells and thus causes them to become smaller? creating small cells? That is one answer I got from a long time bee guy...
