5:11 Chalk brood isn’t a bacteria, it’s a fungus

Thanks for your effort to educate the public about bees.

I think a good reference would be feeding bees by Bob, the sterilization effect of fresh nectar/sugar syrup has on the colony is almost undeniable. Hydrogen peroxide and gluconic acid produced turning sucrose into honey is anti fungal and anti bacterial.

I have chalkbrood infested hive, I notice that the fungus even causes mold in the pollen, I'm not an expert but my feeling is, I think the cause was damp under ventilation. It is contagious and old frames spotted it. Yes a strong resistance queen will help but I don't think it's the whole story. I'm venting the bottom boards under the side walls in future to reduce moisture buildup, also when feeding liquid syrup extra vents need to be opened in the crownboard. I go in on a hot day lift out a frame shake off the bees then as quick as possible I pick out the chalkbrood with a toothpick, I think this helps to reduce the infection also giving the Queen more space to lay me eggs, my hope is once numbers go up bees will over rule the infection and be able to once again kero it under control. Best to dust off and start again as it is a fungal spore that resides in the pollen which in turn is fed to the brood. This is only my personal opinion from my own research and personal experience and expense, if say start fresh. I'm hoping to build big enough to split with new frames equipment, best thing with disease is to cull it. Not a minor problem get rid of it.

Thanks a lot for your helpful information and I wish from you to provide us more and more videos

Unfortunately, giving them a cell from a resistant line doesn't completely solve the problem. The virgin queen, if/when she emerges, may mate with drones which originate from susceptible queens. The only way to truly remove the problem is to introduce queens that are control-mated on both sides of the ancestry to be resistant.

nice video. however, it's not a bacterial disease.

My first colony got infected with chalkbrood. They were going strong and then rainy season came with about a week of heavy rain then the mummies appeared and almost half the colony died 😭 what i wonder about is that even when the colony was down to about less than 200 bees the queen was still alive. Why didn't the colony replace her?

the biggest problem with this plan is knowing what queen line you are replacing her with. I havent been breeding queens long enough to know all the strengths in a queens line. so should I requeen anyway, and hope she is better

I was under the impression that chalk brood was fungal, not bacterial.

i need your help! my bees were healthy and really strong . weather was good and really warm but after that weather got worse and was really cold and rainy and after that i noticed chalk brood in some strong hives. can they heal them self?

How long do you wait to requeen? I have been told to wait 9-10 days and introduce a new queen and kill all queen cells. Do I have to kill all the larva or just the queen cells?

Epic video - thank you! I have a problem with chalk brood at the moment with a hive which I have had to requeen due to a failing Queen and so the hive is week however, by the sound of it I have done the best remedy for chalkbrood - requeening. I do not rear my own queens and so a got one of your F1 buckfasts and I was wondering about your opinion of them for chalkbrood resistance. Should I requeen again with a more resistant Queen or is this one good? Thanks!

👍

Whats the best way to kill the queen?

Chalkbrood isn„t a bacterial infection! American and european fullbrood are! Michael beekeeper from Roumania.

Will they throw out white hard pieces of stuff to front.

This doesn’t really make sense if it’s a bacterial infection…how a new queens is going to get rid of bacteria is a mystery. I know nothing about bees but something about bacteria 😂
