On a lighter note, I stumbled upon this :
Sacbrood virus
From Wikipedia, the free encyclopedia
Sacbrood virus or SBV disease is an infectious disease caused by the Morator aetatulas virus that affects honey bee larvae. When sick, the colony declines gradually with little or no replacement troops, costing 20-80% of honey production.
Symptoms
When sick bees go to work, particularly heavy herds noticed that bees take dead larvae out of the nest. The screw cap on the pupil surface is sunken, and a few small pinholes are present. The larvae die at the new stage screw cap (pupa). At the pointed tip of the diseased larva protruding between the nest holes, the tip of the larvae tilts towards the abdomen. At the larvae's end is a small transparent water bag. Dead larvae have no odor.
Prevention and treatment
The best preventative measures are hygiene of means, transporting tools and beekeeping tools when trading, importing, and transporting bees and products, as well as inspecting and interacting with bees; when importing the breeds, choose healthy, clean and clear herds.
Antibiotics do not affect this disease. Biological techniques such as replacing the sick lord with a royal cap or silk thread, confining the herd for 8-10 days, removing bridges so that the bees thicken the remaining bridges, feeding 5-6 nights in a row to transfer to a new and better source of flowers and isolation from other bee farms and merging the weakening herd.
ยง
Bottom line: replace the sick lord with a royal cap or silk thread
