_______________________________________________________________
The video discusses the evolution of defense mechanisms against Varroa mites in honey bee colonies. It highlights the concept of social immunity and the resistance of certain honey bee populations to Varroa destructor. The study by Dr. Melissa Oddie explores the behavior of uncapping and recapping brood as a potential mechanism for disrupting mite reproduction and improving colony survival. This finding provides valuable insights for queen breeders in selecting bees with enhanced resistance to Varroa mites.

CORRECTION: Dr. Oddie misspoke when outlining the test for sperm counts in varroa to determine a reduction in mating success due to recapping. The intended focus was on examining the spermatheca in female mites, not the sperm in males. Analyzing sperm counts in males would not provide evidence of hindered mating. Please feel free to share your comments and questions. Best regards, Humberto.
What about the buckfast bee ? Weavers bees in tx. Claims resistance bees.
I agree with you , its like we are trying to add crisper(dna) to the bees to get what we want , we cant play God, we just cant.
Locally adapted bees .
Can they be requeened and keep the local adaptability?
We have to pressure the system and select the best bees , ive heard this .
But we are here because nature selected bees without humans and we are studying them.... just doesn't feel right in your spirit does it.....
She didnt say aggressive but she did.
Aggressive bees need more focus, African as great example being resistant
Poly line is interesting, its just selection need breed if im correct..
Test for the chemicals, you'll cry if you had the numbers
Thank you Dr. Oddie and Dr. Humberto Boncristiani for a great interview, as usual. Happy holidays
Same to you!
I have been a bee keeper since before varroa mite and treatments for viruses and other issues of today,I also for many years was a contact used though the state to handle swarms in my geographic area.About 10 years ago I collected my last swarm which was the largest swarm that I have ever seen the size of a very large beach ball ,also the were a very deep brown to black in color something I also have never seen ,I been told that they are not European,well to get to the point they are the most adaptive bees to mites I ever had and I have never re queened just let them super seed ,To the bad side they build up very fast and swarm early and late in the year they are very hard to control that way sometimes I do 2 splits and pass them on. No treatments.
Interesting.
Thank you for some useful info !
I’d be interested to know what size and type of equipment you use?

Barbara, (not being critical) your posting lacks enough context to offer an attempt at any meaningful dialogue. Since this was an apparent podcast, people from around world can post comments so not knowing your location (at least roughly) makes interpreting your comment/observation exceedingly difficult. I, too, have keep bees (here in Texas) since before Varroa was a real problem. But I also have traveled the world and seen enough beekeeping operations to know color variations of the so called European honeybee can vary greatly from yellow Italians to German black {grey} bees. Even the Buckfast bees mentioned by Melissa in this video tend toward a darker color bee than Apis mellifera ligustica (Italians).
The Russian Federation has an Oblast {state / Federal District} called Primorsky Krai located in the far east, bordering the Pacific Ocean - Vladivostok being its administrative center. This region of Asia has had Varroa mite pressure on Apis mellifera for the longest period of time. As a result, I would suggest Dr. Oddie obtain Apis mellifera for experimentation from beekeepers in this area of Russia. Within Russia, honeybees from this region are reputedly known for their Varroa mite resistance.
Did you contacted Dr.Oddie?
@@InsideTheHiveTV I was hoping to communicate to Dr. Oddie about the Russian bees via this post (assuming she follows your You Tube channel). Now for a short FICTIONAL tale - emphasis on ‘fictional’ (so as to make it clear to any potential U.S. Department of Agriculture readers of this posting). Not only fictional but also just a “rumored” event anyway! According to this tale, five of these Russian queens found (cc 2001) their way back in a suit jacket pocket to the north Texas DFW area. The beekeeper involved was experienced and had managed to keep all five queens and their attendants alive on the long flight back home from the other side on the planet. He gave one queen to each of two lady beekeeper friends in the local area and kept three queens himself. The queens were all successfully introduced to colonies and in turn, those hives were encouraged to become crowded and throw off successive swarms. I have no idea if the anti-varroa hygienic behavior is dominant or recessive but they were released into nature to take its course. Not unlike the invasion of Texas from Brazil of the hybridized Apis mellifera scutellata. Now some might see this action as reckless abandon and to those folks, all I can say is, thank goodness it’s only a fictional tale. 😉
Melissa you are awesome!!! Thank you for time
Please look at the work by Cory Stevens and Rondy Oliver. it isn't perfect but it is progress. There is hope.
Golden Ridge Honey farm can also be added to this list along with the entirety of the Russian Bee breeders association.
Awesome! Thanks guys.
Im new to beekeeping but think ive missed my calling im really interested in evolutionary biology and looking to get into queen rearing. Wonder if you could point me in right direction for obtaining good genetics .im in northern queensland australia where varroa hasnt reached yet but its on its way
I tried to listen to this interview, but it took too long way too long to get to the topic in the title regarding varroa resistant bees.
that is unfortunate...it was a really good interview and discussion.
Often there's more to the story than just the headlines. I enjoyed the conversation very much. All of it
I went to the Bee Culture--Diversity in Beekeeping...which somehow was not very diverse as it was pretty much all women that had degrees doing the speaking. They were told to "tell their story" and it didn't take long to find out they all had basically the same story--as is the case here. Go to school with a degree that's not what you're working with today, go abroad, lose funding, realize they're throwing money at anything beekeeping, and go tell people what you learned that won't change anything.
QUESTION:::what is the mite co2 threshold before it dies? How close is it too the honeybees co2 threshold? Thanks
This is a thing for sure! What it is? Idk as a back yard guy does it matter? Small or no upper entrance is a thing for me!
@@bryanbetournay5557I think part of the question is about upper venting,if you're using upper venting or entrance the CO2 won't be trapped in the hive to see the effects it will have on bees or mites. I'm a new backyard beekeeper just trying to learn, not trying to teach .✌️
Its acatch 22 you do better with upper flow thru
venting if you collect huge honey crops as you need to evaporate moisture which is more efficient with air flowing thru the hive rather than having bees fan a bottom entrance to make air from the top of a 6-8 deep super high hive exit the bottom on a hot day .
For Co2 to be trapped your hive would need a small restricted entrance to keep the air trapped moisture co2 heat and all .
1) Young Quality Queens ....2) Brood Breaks a bump in the road that puts the hurt on Varroa populations.
At 20:30 she says cold temperatures help. How?
😮how can we get you in Australia?
I think you just need to send her an email.
Sura 16: AN-NAHL (THE BEE) - Juz' 14 -
Your Lord revealed to the bee: 'Build your homes in the mountains, in the trees, and in what they are building. (68) Eat every kind of fruit, and follow the easy ways of your Lord. ' From its belly comes forth a drink (honey) of many hues in which there is healing for people. Surely, in this there is a sign for a nation who reflect. (69) Allah created you, and causes you to die. There are some of you who, after knowing something, will be kept back to the vilest state of life, knowing nothing. Allah is the Knowing, Powerful. (70) In your provisions Allah has preferred some of you above others. But, those who have been preferred do not give their provisions to those whom their right hand possess so that they might be equal therein. What, do they vainly disbelieve the favor of Allah? (71)
