Day 3 - maybe the worst day so far? Video is the collected casualties from a single hive. I posted 3 days ago about a mass death on my 4 hives in my single apiary at home.
I'm in Southern Tas and we are Varroa free so it's nothing to do with mites.
I'm suspecting CBPV but there are 2 facts that are bothering me.
1) mass deaths starting the same day
2) zero evidence of type 1 infections
I contacted the nearby orchards, they haven't sprayed and won't until the contracted pollinators are moved off-site. I contacted local beekeepers and no one else is reporting anything unusual. The farm behind just hosts a few cattle and I check security camera footage the days leading up and there has been zero activity (except me) near the hives or on the field behind them.
I contacted BioSecurity the first day but they said unless I know it was pesticide drift, they won't test as it's too expensive. And the orchards are 450m away so not like next door.
So that leaves CBPV I guess. The hives do have foragers returning, sacs full of pollen and the like, and they are fine. I feel if they were sprayed they'd be returning worse for wear. It really seems like young and old bees just emerge from the hive and die. Like there is a blob of uranium inside killing everything off.
Anyone deal with CBPV before and can offer me some advice or tell me if what I am describing could be the infection?
As far as all hives being affected, there was some commonality between 3 of the hives. And that's Hive 2.
Hive 2 was very weak due to queen getting trapped above queen excluder for 2 weeks. So I donated some brood from hive 1 to hive 2 about 5 weeks ago.
Then when I inspected last week, probably due to the accidental brood break, hive 2 was very low on stores. So I took stores from hive 3 and gave it to 2.
When frames were donated to hive 2 from hive 1 and 3, I gave those hive a frame from hive 2.
So if hive 2 developed an outbreak from being week, I might have transmitted infected frames to hives 1 and 3.
Hive 4 however is about 10m away and received nothing from any of those 3 hives.
And just another theory, maybe hive 2 was suffering deaths earlier, but because it was weaker I didn't notice. It wasn't until the other hives had mass deaths that I payed attention.
Anyway, just thinking out loud. I'm incredibly devastated but I can't give up. I made a mistake somewhere and just have to learn from it.
We don't even have Varroa where I live so beekeeping here is easy mode compared to the rest of the world. Still feels terrible though, and it's hard not to want to give up when you watch your babies die and there's nothing you can do.
The thought of burning all my equipment and really starting over is heartbreaking though.
Ugh.. I have no idea what to do next..
/Rant over
Edit - I said no evidence of type 1 symptoms but I think I meant type 2 after doing some research. Essentially my bees are shaking, but no obvious dark greasy bees. But then from reading it's only a small number of bees that present those symptoms and i should see a few once I open the hive and can see if I spot them walking around. Will post update later today.
Edit 2 - Some reported on my FB post that they are a few blocks down from me and are suffering the same problem..
Edit 3 - the Bee store about 2km away from me has a display hive that lost about half the hive overnight. Same symptoms of bee death and pre mortem. I no longer suspect CBPV but a pesticide use by a local orchard that didn't care about pollinators.
