Secondary update on the Varroa Front..... The Resistant Mite Spread
We have just received yesterday - results on mite samples we conducted in April across a number of suburbs.
I thought it important to share this information asap as we had an idea it was bad but now we truly know how bad the resistance mite load actually is throughout Brisbane.....
To say we are disappointed would be an understatement, the sense of urgency and communication to get this type of information out to beekeepers that are making daily decisions on thier colonies and finances - has a lot to be desired in our opinion.
These samples were submitted and collected on the 14th April and results communicated the 1st of June.
For us - In that time we have condensed and treated entire apiaries (150 colonies) using Bayvarol and now Apivar. Over $3000 spent on treatments and wages to now learn we have to do it all again as the mites have up to 100% resistance to both products in some of our apiary locations -
a ticking time bomb for entire collapse and spread now.
The attached two pics - one is the data of actual samples we collected (personal data covered for obvious reasons) the other a suggestive map of areas we suspect to be most impacted by resistance. Information below to explain further -
We have asked for DPI to release more findings or to construct a map for us to use but we have been informed their test results are not for public disclosure at this stage.
DPI response is "to continue to use different modes of treatments and to check efficacy rates and suggested to check wash counts again a week after treatment applied".
What has been confirmed is that the Brisbane and Ipswich areas have resistant mites and the spread is vast - areas like Kingaroy, Bundaberg, NSW and Victoria all have confirmed cases of the resistant mite, without testing samples we don't know the percentage of impact.
I'll let you all be the judge of all this information but hope talking about it and sharing it can help you with your management of this pest.
Thanks

Data example pic 1
Using say example 3 in Pullenvale 70 % of the mite sample tested resistant to Pyrethroid and 80% of the sample tested resistant to Amitraz. Highlighted in red due to the high number of resistant mites in the sample provided for testing.
Next line Marburg zero mites tested resistant to both modes of treatment.

Varroa week ending 12th April 2006

- Chewar 2nd Apiary 20'hives avg >20 mites
- Stockleigh 1hive >70mites
- Pullenvale 3 hives avg 8 mites
So just over 12months in from our first confirmed detection of varroa into QLD and it's been a tough learning for most and that learning isn't slowing up anytime soon....
We all as beekeepers get to be a little unique compared to what everyone else in Aus and I'd say the world has experienced when it comes to the varroa spread across our state.
It would be fair to say the sheer amount of colonies across the eastern suburbs of QLD was grossly underestimated by everyone.
The initial and continuing plague numbers have been extreme, we have seen with our own eyes estimated weekly mite re-infestation rates in the thousands. This is subsequently confirmed with weekly mite drops rates in the thousands if not 10's of thousands of mites during effective treatments.
Now add the scientifically confirmed genetic mite mutation resistance to synthetic pyrethroids and synthetic formamdine (this includes Bayvarol, Apistan, Apivar and Apitraz)
And lastly as we are sub tropical and many may have noticed these last couple of weeks we have just started our winter honey flows meaning brood build ups - zero chance of a brood break.
All of this is a perfect situation for varroa, allowing this little parasite to continue its lifecycle and not slow down.
Now this sounds like all doom and gloom for us, for people on the outside looking in seeing death and destruction, no beekeeper in their right mind would want to be walking in your shoes if any of our shoes right now.
So for us in QLD keep on being resilient if you have tried, tested, adjusted, changed your management plan over and over again and you have failed or succeeded you are a great and more experienced beekeeper regardless, just for having a go. Every beekeeper is inclusive of this- natural beekeeping or treatment free, mechanical methods, treating methods or a combination of all of the above - well done from us as you have had a go and you have learned what many beekeepers haven't.
You are and have become far more experienced beekeepers and in an ageing demographic of beekeepers we hope that you can pass on this knowledge to our next generation of beekeepers, as beekeepers are more vital than anyone truly realises and to loose the craft would be devastating.
My final quote for your thoughts and to keep in mind when reading, sharing, commenting or judging others....
I truly believe......
" There isn't a single beekeeper out there that does not have their bees welfare at front of mind right now, doing their best to keep their bees alive with the knowledge, beliefs and tools they have chosen to use and prevent their colonies from perishing" as quoted by me...
Goodluck out there - feel free to share your stories, mite counts and things that are working for you.... negative and unhelpful comments will be deleted as we see them!

Stevo- the wise one out west - he's available for Towoomba / Kingaroy and beyond if you need him.
Wifey- clearly the birthday week continued and I wasn't told, that's or it's a stop work week, wanting better conditions π€·ββοΈπ€¦πΌπ
Video - a super healthy hive in Redland bay double brood with Bayvarol in for last 4 weeks - drone uncapping showed 4mites in one cell- count went from 6 mites to plus 20 in 4 weeks
