Chalkbrood
« on: January 04, 2009, 10:18:18 PM »
I live in Honolulu.  It has been raining lots the last few weeks, and it is cold.  I think I have chalkbrood, but since I have never seen it before I'm not sure.  Do you know of a place that has pictures of it?  My frames have a scattered brood pattern, the larvae looking like they are surrounded with a white fuzzy mold.

TwT, I use that site all the time.

Once started, chalk, because of the time period to develop, may linger for a good period of time. It will limit buildup and take it's toll on hive strength, but will not kill the hive outright.

Sounds like your conditions are ripe for it.  It may clear up on its own, or it may take re-queening to clear it up.  If you don't like your queen then now is a good time to try requeening.  It took me a full year to clear one hive up since I had to wait till late spring before I could get a new queen in there, and that hive never produced any honey.

i think i am the chalkbrood master this last year....

if you have chalkbrood you will see "mummies" like the ones in MB's pictures on your bottom board or entrance.  you may also see mummies in the cells.  fuzzy sound more like moldy brood that is already dead. 

you can take some pics and ask one of the moderators to post them for you.  that will give us all a chance to see what you see.
.....The greatest changes occur in their country without their cooperation. They are not even aware of precisely what has taken place. They suspect it; they have heard of the event by chance. More than that, they are unconcerned with the fortunes of their village, the safety of their streets, the fate of their church and its vestry. They think that such things have nothing to do with them, that they belong to a powerful stranger called “the government.” They enjoy these goods as tenants, without a sense of ownership, and never give a thought to how they might be improved.....

Thank you for all of the help.  I haven't been able to look for mummys yet. This is a nuc with a new queen.  It is getting dry and warm, so it should clear up.

One of the things that many nuc producers experience is that you can make up a nuc from a full size hive or a simple split, etc., and even though no visable signs of chalk were seen in the mother colony, chalk can easily outbreak in the nuc. Not sure if it is a imbalance of bees (nurse to worker, etc.) to  when the nuc was made up, a difference in environment inside the hive (Less moisture control, etc.) or just the added stress of making of the nuc or the placing of the nuc in a full size hive. But chalk can be seen with nucs at an increased level. We always mention moisture and queen replacement with chalk. But chalk is also listed as one of the "stress diseases". And we know stress can throw a normal functioning colony into many problems.

you know I never thought of it that way, good info, I have never had chalk brood but have seen it, I see how after you posted this that some nuc's could have it from different things other than the old queen bee.
