- Cory will teach us about his foray into treatment free beekeeping and motivations for sustainable practices. He will discuss how he set goals to progress toward sustainability, and provide important tips for backyarder and sideliners that he has gleaned on his journey toward becoming an esteemed VSH queen producer in the Midwest and abroad!

Cory Stevens for United States president!!!
🤣
best of the best
Always good information. Thank you.
Our pleasure!
Wax moth larvae do exist early on in the season & you clearly see the formation of several wax moth lines. The chance of it not being wax moth is very small because of the formation of the diagonals. You can even see the where the wax moth has gone from cell to cell through the side wall.
I agree. I was just getting ready to write a comment. On that picture from the start.. that is Lesser wax moth larva damage. I seen hundreds of those over the years. Bees going after them and trying to catch them.. uncapping in strate line
Wax moth larva can survive all winter. They just don't move much, or eat and grow. In early spring with the first flow coming in, bees start to actively hunting them and l can see them on open bottom trays
These are definitely not wax moth caused. And they’re not always in lines either. Pay attention to how many cells surrounding it have been uncapped/recapped. VSH have a high degree of uncap/recap. I’ve used VSH stock for over a decade and this trait has always accompanied it. The usda-ARS had pictures of the same thing on their website years ago. Were the USDA scientists also mistaken? I don’t think so.
@@stevensbeeco767 which USDA scientist? If they did say that then they were mistaken. Even scientists make mistakes. It's wax moth damage, you shouldn't die in this hill as it undermines your good work. I'm no novice. I've 1000s of hours of experience with 1000s of hives.

Greetings from subtropics australia (currently varroa free) your work is inspiring i was planning on starting selling queens soon and breeding for varroa resistance.i was wondering how i would start breeding for resistance now before varroa arrives(varroa is detected in the state below us so will be here within a year or two)so is it basically hygienic behaviour im looking for.
Start selecting for hygiene now with Freeze Kill or Pin Prick methods.
Since the research shows that varroa prefer drone brood why are you not pulling your samples from the drone brood?
That is a great question. John Harbo states "the VSH trait does not seem to control mites in drone brood, but we do not recommend drone brood removal. It is not necessary with VSH."
Where can I buy good VHS queens
What do you do with vsh3 queens do they get used in commercial honey yards
There are commercial beekeepers using VSH queens.
Dr. Stephen Martin’s group at Salford?
clarify?
@@sbgmimedia I think this is who was doing the viral load work on Cory’s bees. Dr. Stephen Martin and his colleagues are doing leading research on honeybee resilience
@@DerekMasselink Thanks for clarifying! :)
Whomever made the intro to your videos...awesome just doesn't cover it!
You mean the countdowns? We can't take credit for that! Thats RUclips!
Cory, that is Lesser wax moth larva damage on that picture. Start pulling those larvas- pupas out with a needle and l guaranty a wax moth larva will pop out
Incorrect. I see uncap/recap starting as soon as brood is available early spring. There are no wax moth larvae around at that time. Definitely not in very strong vsh colonies. I’ve seen this since I started using high expressing VSH breeder queens.
I'm fighting varroa since 77, and I don't remember when I started fighting wax moth. I can see what you're talking about on this picture.. on the side and above.. it's visible.. but for this particular one I would say it is lesser wax moth. The seme creature that spreads deformed wing virus in Australia.. borrows under larva, eating jelly, producing sick young bees. I could make this a very long comment, not in my language.. you all are so concentrated on varroa, to the point that nobody thinks about other stuff bees can smell and "hunt", uncap and remove. Just for this picture, I would say it's wax moth. But we'll never know.
It's good that you're sure about what you're doing.. we need young people like you to move on. Just don't be overly sure. I have a life time of watching frames like that, living on an island where all bees are mine.. and one more island close by, controlling everything.
If you're interested in watching something old.. Ivan brndusic has two YT channels, over 15 years old, showing bees grooming varroa off themself and Lesser wax moth larva damage. Don't get angry at an old guy opinion. I'm always digging around with a needle. And 99% of the time when the uncapped lines are strate it's the wax moth...
@@researcherAmateur I understand. And I don’t think I’ve got it all figured out, but I do have over a decade of experience with high expressing VSH. I have pulled pupae like these that are uncapped like this one when doing VSH assays out of curiosity. There was no evidence of wax moth tunneling (silk, or webbing where they track) I’m sure that can trigger bees to uncap at times for sure. In this case though, I don’t think that is the case.
@@stevensbeeco767 well, with the work you're doing and the bees you have, you could be right. But I can guarantee that we all have some Lesser wax moth in our hives at some point of the year. It's just that it's impossible to see without an open bottom tray under the hive, where we can see them after bees catch them, or their poop.
I really suggest to watch lvan Brndusic old channel and his two oldest videos. It's a shame that he doesn't care about spreading his knowledge. He did alot of experiments before YT became full with gurus, but he took off most of the videos he had. Probably got disappointed with it. Kinda like me.. Keep up with your work. We really need it
I like to mention Brnda in occassions like this.. just so you young guys know that breeding and selecting didn't start with you. And as a country, or even continent we have over 10 years of varroa on you. Almost nothing is new in beekeeping
