HONEY BEE Apis cerana terrorizes VARROA MITE 

from a corner of Asia my bees love to watch ur vdos:) Just keep it up we r glad to find a researcher like u❣

Hello Dr. Humerto! This presentation is flawlessly put together, and I really enjoyed spending my coffee break watching. I hope you have a fantastic week! Thank you, as always.

They worker brood cycle is much shorter than Apis Melifera giving the mite much less time in the capped cell to reproduce. Fewer mature female mite can be produced in this shorter time which gives them a huge advantage (or rather Melifera has a big penalty to pay for the longer cycle). Every extra day produces one more mite per cell...

Thank You very mutch Mr Doctor Boncristiani summing up these significant points. I myself am a very active beekeeper, originally from the Czech Republic, specifically in the south of Moravia. We are the country with the highest density of bee colonies and beekeepers. Most are over 60 years old. I'm going to the point of why I write. I treat varroa mites in combination every year, but for the most part with a so-called biological trap. I have colony mortality in the single digit percentages. A beekeeper friend from another part of Bohemia has a mortality rate of up to 50 percent in some habitats. What all possible viral diseases can Varroa transmit?

Thanks Dr Humerto. I’m planning on raising bees Apis and meliponia in the Philippines. I need them for pollination and hope to convince my fellow province residents to keep bees or at least watch over mine. Apis Cerana seems to be the local feral honey bee and Tetragonula Boroi the stingless bee. I’m struggling with the stingless names as many varieties live in the Philippines and all have local names. Kyowat kululut etc.

I love bees!

Very interesting.

This is fantastic information on Apis cerana! Thanx.

I need these queens for my apiay

⁠did the mite infestation fade afterwards? Have your bees been alright since then? We are just about to get a dose of them in NSW Australia for the first time.

The drones are by definition expendable. So the workers are a legitimate drag on the colony, but the drones are not necessarily. So getting ris of the infected brood that becomes forages is paramount. But a drone mating, with or with out mites doesn't matter. Either way the drones doesn't come back to contribute to the colony.

Hello. I just discovered your channel today. Thank for the great content. I was wondering, do you have a video of identification of bee species? I have about 10 hives I’ve collected over the last few years and have no idea what varieties they are. Would love to know. Thank you so much, I am happy to support your work any way I can. ❤️

We have the Asian dwarf honey bee in Los Angeles. Their stinger is too small to be afraid of. They are very docile. We welcome them.

as far as i have seen, European bees were transported/used in Asia because of better honey production than domestic Asian. but they were not ready for giant hornets as Japanese bees are. this video brings new light (well, for me certainly) on Asian bee as a better fighter in numerous ways, varoa at first. i wonder - how many hives with Asian bees are in Europe, how do they handle with domestic Europeans conditions? just found this channel, wonder how that didn't happened before. thanks. will keep learning from you.

the best adaptation would be for bees carrying a varroa mite to be ejected from the hive or to leave it voluntarily....but there is no research protocol on this subject

Sir can we put apis cerana in a beehive box sir?

Very interesting. Thank you. What triggers grooming?

What is the ratio of the apple cider vinegar to water does John use to spray on his bees?

Honey biee Apis cerana

Quick question, I read that wood vinegar is effective against red chicken mites. Would this be effective against Varroa?

To bardzo ważne dla pszczelarzy ! Bo pszczoły mają kłopoty. Pozdrawiam!

Here in NZ my bee's are NZ native cross they are jet black smaller than normal with three in time the sting beekeepers here don't breed them they're angry to but no mite none my other Canadian bee hives all had mite plus the back bee's work twice as fast the hives are very very clean

I noticed you said that varroa been around for thousands of years, yet I think it's only been in USA for 50 years or so , so what date was varroa first discovered and in what country .Peter 🇦🇺

Please no opinion, conjecture, or feeling...just give us the prove facts

This is interesting, but not the route to victory over the varroa mite which is making the hive environment varroa destructive. 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 thermoregulation 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. 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-heathy bees-zest hive”.

apis cerana have toxic feminism

well, a mite in a drone cell is a mite in prison.. and days pass, and in other words she is done. So l will speculate that by natural selection those bees "know" that it's better to keep mites in prison than to open the capping
