Strange chalk brood

[beesbeesbees]

Alright, so I've just had a look in the beehive (this hive is about 2 weeks after performing a Demaree to control population) and on one of the frames there is what looks like chalkbrood but strangely the only chalky scales I can see in the entire brood box are in this one square of drone comb, this is in the box with the queen and the bees are now covering every frame in the box despite making two splits along with the Demaree.

I have no idea what caused this, the hive has never had a problem with chalkbrood and is in direct sun most of the day, also why is it just this block of drone brood affected and none of the neighboring worker brood.

A Picture would help?

Please tell us how a demaree is going to ‘control’ population? The idea is to increase the population, shirley? Did you do the splits at the same time as the demaree? Watch out for scrubby queens in the splits, btw.

Seems likely that some brood has been chilled? Drones are often found at the extremites of the brood nest. One square what? Square cm, inch, decimetre, foot?

I know the idea because I have had same cases quite much.

One form of chalkbrood to show up is existence in drone brood. It is a sing, that you have some level of hidden disease. It means that your queen has chalk sensitive genes, which you should kick off from your bee yard.

Change the queen to chalk brood immune stock.

I realized this, when I read about Ethiopian chalk brood research. There disease was only in drones.

I could see it so, that drone brood combs had holes. When I bred the disease off, since that drone brood have been 100% even.

It is too possible, that you had kept that one frame outside too long and the larvae have caught cold. The colony may be immune to chalkbrood, but in special case the disease hits in limited area.

That was poor phrasing, but i did do the splits at the same time as the demaree

Oh and, when i said square i just meant about the bottom third of the frame is solid drone brood

I'll try and get a pic next time I'm in the hive
