I mailed a small plastic container of dead bees to the ARS (USDA Agricultural Research Service) Bee Research Lab in Beltsville, Maryland on January 14 and have been waiting for the results. Our new president slowed things down by telling the ARS they could not communicate directly with the public. That made me so mad that I took part in a demonstration for the first time in my life. Thankfully, some of that nonsense has now been lifted and I received the PCR results in my e mail today.
It turns out my bees were infected with Nosema, which is a fungal disease, to the tune of 61.5 million spores per bee. They also had 5.3 Varroa destructor mites per one hundred bees. Together, they had no chance.
What I don’t know, is why the Apivar Miticide strips I applied on August 22 did not kill the mites. Hive number 2 did not get treated until Sept 29, and I removed the strips in that hive after only 37 days, instead of the 50 they should have remained, but the other 5 hives all had the strips for 53 days. It should have worked.
I have no idea why they got Nosema but there does not seem to be a good treatment for that. I am not sure what I will have to do to disinfect the two dead-out hives stacked on my porch. They are full of honey, which might possibly harbor Nosema. I was hoping to use them to start new hives with in the spring but do not want to infect the next batch. I can do a heat treatment but am wondering how to prevent melting all the honey and wax together. I have a small greenhouse that may be able to get up to the required 120 degrees F for 24 hours but I will have to monitor it closely as beeswax melts at 144 degrees.
A 50/50 bleach water solution can disinfect empty combs and wooden ware. Maybe I will have to remove the honey from the frames so I can reuse them the combs.
Guess I will be experimenting yet again.
Who needs a science based job when my whole life seems to be an experiment?
Please, let the other four hives be healthy. I am doing all I can.
