One of my hives has chalkbrood. I see the little ‘mummies’ on the coreflute bottom (which I have in the bottom slot). I have been removing it and cleaning them off- but more appear over a few days. The colony seems very active and strong in numbers- and has built out several full combs of honey over the last 5 weeks in their flow hybrid super. However they have been slow to start working the three central flow frames.
This colony came from an overwintered Nuc- I noticed some of the frames looked to be quite old when I installed it early in spring. I am planning to transfer the colony to a horizontal hive in a few weeks and plan to rotate out all of the old frames over summer/autumn. I might hot wax dip the frames I take out to kill off any spores.
Since I saw the mummies I have not done an inspection of the brood chamber yet: I plan to do it shortly. What should I be looking for- and is there anything to be done? I have three other hives in the same apiary- I am slightly concerned about cross contamination. I will be sterilizing my hive tool after my inspection…
I had thought this was more of an early spring issue- and exacerbated by humid and cool conditions. The season has been all over the place with unseasonable rains and a few cool nights- but still it’s a Mediterranean type climate in summer here in Adelaide- alongside the hive their is an olive tree covered in fruit just now… Is it likely that this will clear up over summer?
