English summary: No nectar flow so the bees can easily rob a weaker colony in case they found it. This small colony had no chance once the bees entered and when we checked all bees were dead and the food gone. Luckily, the loss was limited since it was a new born unmated queen.Just nuContinue reading “29 Juli – röveri”

English summary: In our resistent colonies we have seen about 60% cleaning rate in the drone combs (DBVSH=Drone Brood Varroa Sensitive Hygiene) and now we want to check if the bees also clean out worjer brood. We have taken photos everyday of one comb and yesterday we saw one cell that was opened. We tookContinue reading “28 Juli – Indikation att DBVSH är länkat till VSH”

English summary: We released our newly purchased black queens that have been caged for one week to ensure they will be accepted by the colonies.Eftersom svarta nordiska bin luktar annorlunda än de gula buckfasthybriderna är det svårare att få en ny drottning accepterad. Vi har insett att man måste börja med en liten avläggare ochContinue reading “27 Juli – frisläpp av svarta drottningar”

English summary: A reader pointed out the risk of overheating on a warm day since ventialtion could be an issue due to the paper blocking airflow. We have not experienced this but if one uses a ventilated top plate with insect net, see below, this potential risk is overcome. We use this solution when weContinue reading “22 Juli – tillägg till hopslagning av samhällen.”

English summary: We have purchased two black queens which we put in two small hives and we will keep them caged for a week to optimize the chances for acceptance. We also exchanged a queen that made aggressive bees and we use a technique with paper between the boxes in two places where the newContinue reading “21 Juli-Drottningtillsättning till stort och litet samhälle”

English summary: No nectar flow in our forest apiary so we have to give back honey combs that we collected earlier. There seem to be plenty of pollen and now we saw orange pollen of unknown origin. Mite infestation is low on all hives so hopefully some lnes are resistent – we will see inContinue reading “19 Juli – svält samt orange pollen”

English summary: This year have been notoriusly poor with honey and even the Linden flow missed. When the high temperature arrived the Linden had already passed. We took a swarm whwere they had built combs which we secured with rubber bands but the bees did not approve and throw out the rubber band after áContinue reading “17 Juli – ännu ett missat drag samt grönt pollen”

English summary: The droon season is now over and its time to make conclusions. We seem to have a few lines who perform DBVSH (Drone Brood Varroa Sensitive Hygien), a novel resistant trait against Varroa destructors. In the images we can see the progress of the bees cleaning out three cells which we beleive isContinue reading “11 juli – slut på drönarutskärningen”

English summary: We collected some unprocessed nectar that we found on the combs and put them in the fridge and now that we have a draught in our forest apiary we gave some of the smaller hives a bit of feeding from the fridge. We also saw some black pollen in the hives, perhaps clover.Continue reading “9 juli – stödmatning, svart pollen samt strejkande drottning”

English summary: There are disputes whether feral bees would build smaller cells, perhaps as small as 4,5 mm, and if thsoe small cells would be beneficial to reduce Varroa fertility and thus the total population. We caught a swarm that had built 10 combs and when I measure the cells it seems to be sameContinue reading “Små celler naturligt för bin?”
