Impact of PROPOLIS on HONEY BEE health and pesticide exposure

Impact of PROPOLIS on HONEY BEE health and pesticide exposure
Impact of propolis on colony health and pesticide exposure in agroecosystems
InsideThehHIve.TV is proud to announce that Dr. Mike SImone, a honey bee researcher at USDA-ARS, Baton Rouge, LA, will join us LIVE to discuss the impact of propolis on colony health and pesticide exposure in the agroecosystems.

Dr. Michael Simone-Finstrom is a Research Molecular Biologist. His research has focused on individual and social mechanisms of disease resistance, including resin/propolis use, hygienic behavior, and genetic diversity. His current work aims to add to this line of research by more fully understanding how these traits work in concert in order to promote them within the beekeeping industry and identify components of viral resistance in honey bees.

Excellent information that non-researchers can understanding. Thank you both!

Many thanks... I live in Australia and have Horizontal Top Bar Hives. The ladies stick them up really well. In my area I have lots of Gums, Iron Bark, Wattles, Pine's etc. Yes, i can attest to the fact that when I stopped removing the propolus from my top bars and left it on the chalk brood issues we get from time to time due to tropical weather greatly reduced. Now I know why.

Great presentation that has enhanced my understanding of this important bee function.

Thank you for putting together another informative study,
In the area of why proplis is not so common in selected breeding, I believed it comes front historical information of Brother Adam at Buckfast abbey,
The period of early 1900s to where the inbreeding and mixed type breading to creation of a better bee, his list in doing that had a reducing of Propolis, successful at that time, it's both written and premonition towards it, it's only had a following, but people wanted the buckfast and just followed his teaching, it's only now! that this type of research is changing peoples way of thinking.

I have hives on an organic farm that are gummed up with propolis. My other hives have a lot less propolis.

All hives are treatment free.

I was wondering more sources of propolis was available on the organic farm.

Anyway, excellent video. I wont be so keen to clean the propolis away from my hives.

I am finding that regardless of rough lumber or smooth lumber I see no propolis being used to coat the inside of the hive like they do in a tree.
Any boxes where I see added propolis being used to coat the boxes is when I use lumber that has not been kiln dried or has gotten wet and mold has formed on the box.

This year I am seeing much more propolis in the hives than I ever have and I think it has to do with what I have been giving the bees for frames of drawn comb.
I have not gone into a trial yet to see results pertaining to the condition of foundation being placed in the hives to know if the condition is what makes the difference.

The one factor that I believe determines if the bees will coat the boxes or not is the presence or lack of presence of fungal spores and other pathogens on the wood being used to build the boxes.

Kiln dried lumber will kill most if not all fungal spores.
In trees there is a large amount of fungal spores and pathogens present in dead, dying and damaged trees.
I would assume there is a certain amount of bacteria in the damaged, dead and dying trees also.
We are not going to see this in the kiln dried lumber.
In nature the tree resins naturally suppress fungal growth as well as other pathogens.
It is only when the tree is dead, damaged, or dying that we see the breakdown and lack of resins in the damaged, dead and dying tress.

This year after having to start all over again, I have open bred Minnesota over wintered nucs and Hygienic Italians packages.
And both are bringing in an abundance of resins and producing lots of propolis.
Based on having these two strains of bees I would have to believe it is not the strain of bees that dictates the amount of propolis but the internal environment of the hive that promotes the abundance of propolis.
Voids in the hive such as gaps between frames and boxes is an example of internal factors.

Another thing I have seen over the years concerning propolis is when the bees choose to store honey next to the brood rather than move it up, they will generate more propolis to pack between the frame end bars to drive them apart to build deeper honey storage cells.
I have seen the bees move frames as much as half an inch for this purpose.
But never have I seen the push frames when storing all the honey above away from the brood.

Also when I give empty frames for the bees to build their own foundation and cells, they use propolis in the building of the foundation.
Using commercial foundation the bees would have no need to produce the propolis for comb building.

In my hives I have a few that I've roughened up to encourage propolis build up. It's not enough of a count as science but there is a significant mite count difference between these and the smooth boxes. I've also noticed a significant difference in the condition of the wood from one vs the other. The propolized wood looked to be in good condition while the smooth had started to mold and develop soft points. I've collected a bunch of propolis from cleaning frames and plan on coating the new boxes hoping for the same result.

Very informative presentation. Many thanks Humberto for making it happen. Can't wait for the next one.

Thanks for nice time. The story of propolis is complex, we see. I gained some knowledge during a visit to some companies and laboratories that deal with the analysis of the composition of propolis in South Korea. The story of propolis took me from a beauty salon to a nuclear reactor plant. High technology in that country has enabled an excellent business in which propolis is the central product of the hive. With reason. We need to know a lot in order to conclude propolis and its functions.

[tadatada]

Absolutely briliant and interesting. It ecouraged me to make few hives with rough wood for observation. Like and sub right away.

[jorgemurillo-yepes]

Excellent information! I have collected propolis from plastic drum top-bar hives by means of covering the internal surface with window mosquito and also with Sarang nets, with reasonably good results.

[nordichoneybeeandqueenprod]

I use burlap as inner cover to promote propolis envelop in all my hives.

Посмотрел Ваши ролики классные, 👋👌👌👌👍 остаюсь

Great presentation. Any plans to have Marls Spivak on or Renata Borba?

[ninon]

Great vídeo in a great channel.
Thank you!
Obrigado!

[donaldlippert]

Awesome video. Great guest. Interesting topic. Many thanks (from Papua New Guinea).

[gilfisher]

I want to see these walls full of propolis and how they are constructed, please

[grounded]

I would have to question the self life of propolis in its form found in the hive due to the fact I am seeing bees rob propolis from stored boxes and frames, stored near the bee yard.

[BeekeeperUK]

Thank you for your amazing information presented in a clear and calm way 🙌💐

[nadernaderi]

Do you know how and what Egyptian used the propolis for?
