Hi Allen, Additionally, the test was done with AHB which is naturally smaller than > EHB,> reply: The bee is small only due to its natural comb sizing. Allen, where would a source of 4.8- 4.9mm cell combs come from? US and Canadian beekeepers and European beekeepers for that matter all use foundation and at 5.2 and up. South of the border there is much more use of natural combs without foundation. so I wonder if the results can be applied to EHB and if so, if the > cells would be larger for EHB? reply: I don't see why not. I have colonies of carniolan type bees right now that are on 4.8-4.9mm cell sizing(Non- Lusby stock). I know Dee suggests 4.9 top tolerance. Maybe as the bees move north and up in elevation the top tolerance maybe as high as 5.05mm. But for doing the ground work for the average beekeeper 4.9 is a good sizing and in time one can see if it can be stretched upwards for EHB. Now Allen I can understand beekeepers looking for a less labor intensive way. I started with a base of 64 colonies. Have suffered a 75% loss each year(with minor replacement). On the first year of regression the bees pulled an average of 2-3 small cell combs (4.9 top tolerance). No chems of any sort have been used and only FGMO for 4 yrs prior. Then second year shaking bees onto these bait combs and culling the rest you gain another 6-7 combs,with each season the bees locking in better and pulling more and more. Very slow work as you can only accomplish what the bees allow. Then you have to figure mite immigration from neighbors yards ravaging colonies whom are already struggling to handle mite loads as when regressing the mites don't really give you a break. The shakedown process puts enough stress as it is. But no other method work as well and speed is everything especially coming out of the pocketbook. Natural selection? Oh yes, theres that too. > I think there is definitely something to this and that enlarged cells > are a bad idea.
