Interview with @stevensbeeco767 , @NaturesImageFarmGregBurns , and Dr. David Peck at Hive Life 2023.
Cory Stevens and Dr. David Peck both agree that selective breed of honeybees in combination with IPM strategies is our best path forward for Varroa Mite control long term.
We need more queen breeders selecting for mite resistance!!! In order to get that, we need to make it easier to select for mite resistance.
I think a promising avenue is a combination of OAV / Screened Bottom board mite population monitoring on EVERY hive, plus hygienic tests on good performers. The work that Kaira Wagoner is doing with UBO (Unhealthy Brood Odor) could make it fast and easy to find hygienic bees.

This conversation sums up so many thoughts, debates, and discussions I have had over the past year, thank you guys for this! Unfortunately the SMR / VSH terminology is still quite confusing and controversial. One complication is that I think VSH may not actually be Varroa-specific at all. My thinking is that colonies performing “varroa sensitive hygiene” are probably better at detecting stressed brood or signaling stress and detecting stressed brood. Reproducing mites create more stress because there are more individuals feeding on the brood. Unhealthy brood (such as brood with viral infections, including viruses not spread by Varroa) are stressed because they are sick. Bees better at detecting these stress signals are going to be better at removing varroa, but should be better at removing brood unhealthy for other reasons as well. Page et al. 2016 showed us that Apis cerana likely resists varroa at the colony level through susceptibility of brood (varroa infested brood die, and are thus easy to detect). Apis mellifera brood is much more resistant to varroa (varroa infested brood don’t die right away) and thus the varroa is more difficult to detect and the colony more susceptible. So I agree, it’s critical that we keep selecting for more resistant bees, using as many different mechanisms of resistance as we can. Tropi may be knocking at our door soon and we better be ready!
Kaira, thanks for taking the time to comment. I’m pinning this to get more eyes on it. I’m very excited about your UBO work and am on your waitlist already. It’s got the potential to be a key in selecting for resistance.
@@DuckRiverHoney Thanks for your interest and glad to hear you are signed up. I’m really excited to get UBO out into the hands of beekeepers and breeders to try out themselves. Thanks for the great content here!!!
This is why I am so interested in the UBO. I've been thinking for years that there has been too much focus on trying to just kill the mites. When we should be raising disease resistant bees. If we can select for a bee that not only is more resistant to viruses but also keeps a low percentage mite load, that would be the ticket!!
Testing is the key. Testing for mite loads, implementing IPM on a per hive basis, plus testing for specific resistance traits. Specifically, labor efficient / economically feasible testing. Testing needs to level up.
This video should be played at every beekeeping meeting at least once a year! And we need a follow up discussion with Cory Stevens and Dr. Peck
Nathan, you pulled it off. What an informative dialogue you shared with us. Thanks.
I brought in some New World Carni into my program that I'm hoping will improve my stock.
Thanks Russell!
Great and interview with Dr.Peck and Cory Stevens. Got a chance to chat with Cory and he is doing a lot of great work. Hope to see Dr.Peck next HL.
Thanks for this video. Good stuff🤙
Thanks, I appreciate it!
there is great headway being made on this problem. the better job the bees do at control, the less we have to be involved, the better for all
Agreed, I think a lot can change for the better in the next 20 years.
I have watched many of Dr. Pecks an Cory's interviews or lectures va UA-cam,🤔I find them very interesting and have even begun to understand what they are talking about over time.😲The more I learn about honey bees the more incredible they are.🤯 Ty Nathan and Greg for sharing that with us .👍
Thanks! I learn a lot from those guys. Applying knowledge is the trick though…
This was a great discussion! yall hit the nail on the head.
Thanks!
excellent work
Thanks Ian. Have you looked into the UBO hygiene testing yet? Very promising. Michael Palmer has been trialing it. Could make hygiene testing relatively fast and painless.
We’ve invited Karia up to our convention
Awesome. I’m really excited about it. Better testing is a holdup across the industry.
ohh, gotta be careful calling commercial beekeepers lazy! Its not laziness, its practical commercial application. Its about animal husbandry
Efficient and lazy can describe the same behavior. If you’re referencing the part I think you are where Dr Peck mentions lazy beekeeping, I don’t think he meant anything negative.
Oh that tone permeates through the back end. It’s not going to help gain traction. It’s not laziness or looking for the easy way out. It’s about the unfortunate fact of businesses that demands maintaining the here and now along side the progressive actions into the future
@@DuckRiverHoney I'm confident Dr. Peck was referencing "management-free" beekeeping.
Yep, I agree with that. That’s a good, precise, term for it. Using precise language is something I’m not great at, and it opens you up to people taking your words the wrong way.
Your video sure has opened up a lot of dialogue, none of which has focused on what I’m complaining about. Rather, that point is pretty much accepted as such but it’s has acted as a bit of a hook for guys to watch the entire video.
:) keep up the great work
What a great discussion….Thank you all!
Thanks Moe!
Great video Nathan!! Lots of great info and discussion. Also enjoyed chatting at Hive Life. Looking forward to Spring!!
Thanks Keith!
This was a fantastic conversation with some really smart people and I appreciate you filming this.
Thanks Matt!
Thank you to all involved putting this video together. I'm going into my 3rd year keeping this spring and see a big difference in good bees that surely have some mite resistance. We need as many on board as we can keeping bees with some sort of mite resistance or tolerance.
It’s the path to progress!
Much appreciated that Nathan. But wow, what a lot to take in. Great podcast. I look forward to bringing in the best queens to my operation regardless of cost. You get what you pay for.
Thanks Rod!
Great interview/discussion as always.
Thanks!
Great question about symbiosis? That was good content, tahnks!
Thanks!
Nathan, This was an outstanding discussion. This is another example of what the Hive Life Conference has made possible. You and Greg put together a fantastic discussion that benefits all beekeepers. SML BEEs / SWVA
Thanks Craig!
Just stumbled across your channel. Beekeeping is something I’m looking to get into. I’m not too far away if you have any classes in the future.
I appreciate it. I’m no planning on doing classes, but maybe someday.
Absolutely awsome discussion. Having a background in biology myself, it was great hearing the things being done from two aspects. I do believe that a combination of avenues is the way to managing mites in our colonies.
Such an informative discussion with David and Cory. Where else but Hive Life could bring all four of you together for such a great interview. It was good to see you again and I encourage you to keep making the quality content as you have been doing these past years.
Thanks James, I appreciate it!
Very interesting conversation.
Thanks Joseph! Thanks for the honey.
Only just saw this, great interview Nathan. Even though I was at hive life I feel I missed a ton of stuff. This brings me up to date with a lot of terminology I had thought I understood but had got a lot wrong!! I personally am not a big believer that VSH will ever have a huge impact on Varroa management without significant loss of other traits, ( trade offs) but I am remaining optimistic . Like Dr David Peck and Cory say it’s probably better to hope we can at least increase the level of VSH in some ways and hopefully with other IPM and better treatments we can move forward! Nice work. Well done!!
Thanks Richard! You know, I did a honey swap at the conference and got honeys from all over the US. I sure wish I had some honey from Europe, you know, from some random area, such as the Brittany area of France. If only I knew a handsome English speaking beekeeper over there…..
@@DuckRiverHoney 🤣🤣🤣🙌🤗❤️ pm me your address, I have some to send to others too. Will see what I can do! I will speak to that handsome beekeeper!! 🤣
Done! Send me yours too.
Solid content big dog
Thanks!
Thanks Nathan I feel like the path is set to follow only getting beekeepers on board is the part I'm struggling with.but with more experience in bee keeping people start to catch on .I look at it like this if u just save on one treatment a year then progress is being made.
Mark I think testing is the answer. The real value in what Randy Oliver is doing is testing for mites in each hive and implementing IPM on the poor performers, and breeding from the high performers. We need labor efficient methods to do the same.
I totally agree maybe teaching the Harbo essay will help. beekeepers need that info I'm just starting to lern how to test myself. I'm thinking we need to hop over to Corys place and join the vsh harbo test group and video that
I’ve already asked Cory if I could film it. He’s in.
@@DuckRiverHoney Let me know I'm in!!
Bit late but my concept is Combine all the natural way of keeping Varroa down like VSH where they groom/kill the mites away. My plan is to try and combine all the treatment free methods along with brood breaks with freezing drone cells, then when I put the drones back in a few days later powder sugar to get then to groom the last few away. Thats my plan for next year since Ive already tried the break and powdered sugar this year and I dont want to ever chemically treat my bees
Start with good stock!
Loved the 2 different "species" of bees concept your raised...feral/forest bees (survive) versus our bees kept in a box (thrive). I don't want bees just to survive, I want them to thrive in the way I define thriving (honey, growth). Also, I try to talk to all new beekeepers about mites since, as was pointed out, it is not at the forefront of beekeeping for them partly because the impact of doing nothing is not seen for possibly the entire first year. Therefore it is not so urgent for them to recognize the need for treating/managing mites. As you know In their first year they are still rapidly approaching the "peak of mount stupid" on the Kruger-Dunning curve so we experienced beekeepers have an obligation to help them not become part of the problem as you said. Great video!!
Thanks Dwight! I love the Kruger-Dunning curve. Just have to avoid the pit of despair 🤣
Can you say Tropi?
We better get some more eyes checking out Tropilaelaps than anything.
3 months from infection to death of hive. And no the 36 hour broodless period doesn't work.
Man what an interview very eye opening I wonder if the vsh queens are production quality
Cory has a lot of queens go to commercial producers. They usually want breeders though, because they can make their own.
@@DuckRiverHoney if you buy cells how much time do you have from the time you pick them up to the time you put them in a nuc ? I would have a days drive home
He overnights virgins. That’s what I’m getting from him.
I buy his virgins and then pick the best production colonies to continue make queens from
That’s what I’ll do. I want to push VSH into my bees and then select for high VSH bees that I like working with.
The “lazy” way I believe David is trying to present is is not trying unpopular or not traditional methods and doing the status quo. Like all the conventional miteacides that are being used.
The non”lazy” way is not doing the status quo and trying something different and controversial like VSH and/or grooming and natural selection.
We have been kicking the varroa can for 40 years and most still don’t have faith that bees will ever be able to handle without treatments
Jeff I believe testing each hive and implementing IPM on poor performers and breeding from high performers will be the key. Fast and easy testing methodology is the holdup.
Most hobbyists beekeepers don’t have queens on standby to replace poor performers. I had same problem till last year and it’s a struggle if one doesn’t have em. I struggled for many years and natural selection was difficult due to poor genetics in our DCA’s. A good business model is to keep supplying queens that aren’t resistant so all the keepers that don’t want to treat will just end up buying more packages in the spring
@@nkapiariesjeffbeezos796 I think its about replacing your current stock with VSH queens and go from there. All feral bees producing drones for the most part are intuitively mite resistant. So, if you flood (even if its small) the DCAs with VSH/SMR whatever terms you prefer it will make a difference.
Sorry but this went way over my head on the practical end. Would someone please. explain in practical English what the heck Cory meant at 28:28 ongoing..
Natural selection is letting the weak bees die. Not just with mites but also with honey production and the colonies ability to increase and decrease population to match nectar and pollen flows.
Thanks Jeff, I appreciate the assist
@@DuckRiverHoney ..did the other response get deleted?
I don’t recall another response…did you post something else?
Maaaan, if only CRISPR were being applied to this to edit and insert specific genes from one line of bees into another...
I don’t know how helpful it would be. With multiple matings and short life spans it could get expensive quick, and washed out even quicker.
