Honey bees defeat Varroa mites

_______________________________________________________________
DESCRIPTION
In our search for the perfect honey bee, I am covering the main scientific discoveries about genetic traits already found related to varroa mite-resistant honey bees. In this video, I talk about the first evidence found, in Apis cerana, that honey bees can handle Varroa mites themselves.
Can beekeepers and researchers use this interesting information from the Asian honey bees to help the European honey bees?
Is this the oldest way to help honey bees to fight varroa mites?

Good stuff Humberto. I'm hoping that in the next few years we start to see some breakthroughs in the States for Mite treatments and/or resistance . .

[dcsblessedbees]

So why can I not buy Asian Honey Bees? And or why are we not just crossing the Asian and European Honey bees? I know I am a brand new keeper but seems simple?

[realitycheck]

My colonies are evolving and learning to deal with them naturally...

[GEEZBEEZ]

Interesting video. Thanks for sharing your knowledge.

[MinnesotaBeekeeper]

Humberto how do they kill the mites? Similar to a Bee Weaver leg chewings?
Looking forward to your next part. Thank you.
Grooming. It's interesting to see people's reaction when I sift powdered sugar into a hive then show them the bottom screenboard mite drop. It's just a demonstration of phoretic mite removal via grooming, nothing more.

There was a study and a report done by the Australian department of agriculture and water. Titled "Varroa mites on Asian
honey bees in the Torres Strait"

This study contradicts what your saying in this video. It's worth a read.

Grazie per la traduzione in italiano .

Hello Umberto-off topic. Do you know a lot about OAV? Does it’s application kill or harm open larva and brood? I’ve heard it does and want to know. Thx.

[dimkoron]

Misleading title, we have no progress against varroa just wishfull thinking .

[williamsummers]

If you change the hive environment by changing its design features you can be varroa treatment free. You just need to make an environment that reduces the varroa replacement value over each generation. This is not so hard. Forget chemicals. Honey bees in Cuba and South America have apparently learned to deal with it. The reason is likely to be that the climate is hot and humid, both factors of which can benefit the bees against varroa in their own way.
The propensity for varroa to die away in a humid hive was found out by accident when a laboratory hive was accidentally left at a higher humidity than others and that one lost its varroa. The precise mechanism of varroa destruction by humidity remains a mystery, but with a very small creature it probably drowns it.
The standard vertical bee hive entrance at the floor level of a thin walled vertical hive with ventilation at the top causes a cooling stack (or flue) effect internally. This cools the hive in winter and takes away its humidity all year. If, in a standard vertical hive the bee entrance/ventilation was placed at the top of the brood nest (under the queen excluder in summer) a VIBEZ (Ventilated Integrated Bee Entrance Zone) is formed giving a “bucket” of humid air in the brood nest below.
Wrapping the brood boxes of a thin walled vertical hive with aerated concrete blocks is also a major benefit for the bee’s thermo-regulation duties, particularly in winter.
The temperature of the brood nest is important in the fight against varroa as it affects the pupa hatch period and therefore the time available for the varroa to mature in the cells. The temperature over the time of day and position in the brood nest affects the pupa temperature.
Below 29C. and above 37C. the pupa die. At 35C. it takes 10-11 days to hatch. At 31C. it takes 14-15 days to hatch.
If you are already committed to the thin walled vertical hives as most are, consider making those modifications to test their efficacy.
If you are not committed, the ZEST DIY hive is functionally free of varroa in so far as it does not need treating for it. It has many other advantages in cost, effectiveness and benefit to the bees and bee keeper. It is made from aerated concrete blocks which have 39 times more Resistance (R) to the passage of heat than a thin walled wood hive, is humid and functionally free of varroa.
It also has top entry. If you want to know more about varroa free hive design go to the ZEST web page, and read the free E-Book going to pages 21 to 24 and 50 where the mechanism for being varroa free is explained. There is a U-tube that you may also want to view titled “Build your own bee hive-healthy bees-zest hive”.

A new queen is born in a queenless box but there are three to four drone bees in this box, will the queen mate? Please inform

[badassbees]

We've had truly feral bees dating back hundreds of years and some of them still get slammed..people always selling "resistant " bees, my ass vhs, smr, grooming,mauling is hygienic not resistant. Some resistance yes, resistant no..my bees are best bees on the planet I believe, especially compared to everyone else's I've tried or helped with and they can't all beat varroa, although they do handle them very well compared to Georgia and Mississippi and Cali queens I've tried...the Russian bees can't do it hardly either, we don't have those bees, their bred down with watered down worn out genetics , I'll stick with my bees.

[amwartwork]

paul stamets talks about this with his work on funghi

[philweber]

Why not replace apis malifera with Apis cerana?

[lagrangebees]

Are Apis Mellifera and Apis Cerana genitically compaible? If so, maybe creating a hybrid would help transfer the grooming behavior over? Although I Randy Oliver's resistance breeding program is making great progress last I heard (close to 50% resistance, so still a few years away)

[drpk]

Would be interesting to hybridise these two varieties. Hopefully this time we woulndnt get something like Africanized bees.

[luckydragon]

its the size of the honeycomb - free bees make the comb smaler - most problem with Varroa have bees with bigger honycomb size - a few years ago i watch a documentary about that issue - the problem with Varroa came from the idee to make the size of the comb bigger to earn more honey

[ronny]

I think if apis mellifera could grow naturaly and not by beekeepers Selection they would find a way to handle that enemy. Nature find a way, every time.

[sonofthunder.]

i thought it was proven they dont feed on hemolymph

[drumcdoo]

Intrigued to know Humberto, why Asian bees (Apis Cerana) are not used to produce honey across Europe? Is it perhaps because of a warmer climate they come from and cannot survive European winters or somethhing else? Would seem an obvious solution to control a devasting problem...
