Finally I find someone who actually explains and shows how to use this grafting tool. I have watched other videos using this tool and they fumble about trying to slide the larvae off as they were NOT bending the tongue while placing the Larvae. Also never saw anyone just slide it down the side of the cell to pick up the larvae. You made this look easier than I ever thought it could be. I feel much more confident that I too can graft successfully using your instruction on how to use this grafting tool. Thank you
Would you consider giving a reference as to where a microscope like the one you use in the video can be purchased? This presentation is one of the finest productions on grafting that I have ever seen. As a side note, I am amazed that this collection has not exploded with viewers. Please do not let the lack of immediate success in any way detract from the knowledge that you have probably made the finest collection of videos on bee keeping that has ever been produced. This has to be a "National Treasure." Thanx for all you efforts and kind willingness to share.
Hi Larry Thanks for your kind remarks and question. I inherited the scope we use and it doesn't seem to be available now. This link is to a new microscope that we have started using: www.amscope.com/10x-stereo-binocular-microscope-boom-arm-light.html
I appreciate your very generous comments Larry! You are are #1 supporter !!! Please share the links to our videos everyone :) WE did the videos with $ from a crowd funding campaign so it's all free! The video series will soon be available at cost on a flash drive.
The microscope is called a stereo microscope. You can search online but finding one with an arm like that one might be impossible. They range in price from $89 and up.
A pair of reading glasses should be all you need, one slightly stronger than what is comfortable for you to read a News Paper is what I use. This guy probably has several uses for a microscope and since he has it he uses it.
Hi Paul..very informative and very well explained. I like your style of teaching. Love your video's and look forward to seeing more of them . Many thanks cheers Darren from New Zealand
Thanks Darren! We are working on about 20 more videos. Hope to have them posted later this fall. I had a great time on my bicycle in New Zealand 30 some odd years ago. Lots of very progressive beekeepers there. If it weren't so darn far away I might have stayed. Cheers from Canada!
u do a great job with teaching us all u make it very simple nothing confuses me with your teaching I really like the way u teach about bees i wish u would do a hole lot more thanks for what u are doing
Thanks Frances! We will do some more videos each bee season but not as many as we did last year. We had some money last year from a crowd finding campaign to hire a videographer.
Outstanding video on technique! I'm old and God gave me calloused hams for hands. I can't see well enough to graft anymore so I just use Grandkids...no video games till this is done kids. If none of them are around, I just use an old cell punch tool that I made years ago. Thank you for sharing your work !
The royal jelly and larvae are both sticky so they cling to the queen cup when its inverted. In a natural situation the larvae and royal jelly in a queen cup are positioned the same way. Thanks for the question Joe.
An excellent and informative video. I am new to grafting and queen rearing but am hoping to have a go for the first time this coming season. A couple of questions though are how do you transport the brood frame to your grafting station without the brood becoming chilled and what is the maximum length of time you aim to have the larvae outside a hive? Or is the ambient air temperature during the summer high enough that chilling is not a problem?
The ambient temperature during grafting season is adequate for survival of the larvae and pupae. We try to have the frames back in the hive in about an hour. Temperature is less of an issue than desiccation. That's why we keep everything covered with damp dish drying towels - all the way from and back to the hive.
Thank you for the video. It is awesome. My question is; how does the bees recognize the queen cups? Is it because the queen cups look different or bigger than other regular colony cells where original worker bee larvae were?
Hi John Yes they do recognize queen cups. The ones made by humans are very similar to ones made by worker bees are. They hang down and are larger than worker cells.
How large of a cell builder do you put them in and do you finish in a separate box? What is your average on cells that take? Do you find a difference in size of cell and queen quality? How long can you bank a virgin before she won’t mate? What treatments do you administer prior to going into winter?
Hi Jake You could see more about our queen rearing techniques in some of our other videos. We did two on our cell builder method and others that show mating nuc management and one on winter prep. Queens mate between five and ten days from emergence. I introduce queen cells not virgins .
All of the videos are excellent!! I noticed that you use wax cells. I wonder why you don't you plastic ones. Have you ever tried them? Is the acceptance rate lower with plastic ones?
Hi Sotiris Thanks for letting us know you like our videos. 21 more on the way very soon. I've never been interested in plastic cups. Another disposable plastic product where beeswax cup/ wooden base is renewable and decomposes when I toss it over my shoulder as I check on mating. Plastic cups work well for producing queens too. I think the acceptance rate is very similar but I've never tested it. For hygienic reasons plastic cups shouldn't be reused. I know many beekeepers drop them on the ground when they are done with them :(
I see a lot of people showing how they graft the worker cells.. but no one talks about the queen cup prep. Do you put royal jelly in them before you put the larvae in it? can you please explain it to me?🙏🏽🙏🏽🙏🏽
Hi Scott Room temperature is fine for an hour or so. We have a no AC in our building and don't use a heater. Keeping the larvae from desiccating is more important than keeping them at brood nest temperature.
I have a question, do the cups already have some royal jelly? Or does all the jelly come from the cell with the larva? Also what keeps the larva from just falling out of the cell when you turn it upside down to put in the hive?
We 'dry' graft. That means the cells aren't primed with royal jelly. Some royal jelly is transferred with the larvae when a Chinese style grafting tool is used. The jelly and larvae are sticky so they stay put but we are careful to not bump them.
UoG Honey Bee Research Centre thank you so much! You are the only person that has ever responded to those questions! I’ve asked so many people! I think I understand how to do this now, thank you!
No video of this yet. We cut the wood pieces and attach them to the graft bar with liquid beeswax. We then attach the cups with liquid wax. In both cases the liquid wax is applied with a syringe. I used to make the wax cups but now buy them from www.kelleybees.com/
We start to graft in early May -about when dandelions start to bloom. Our drone supply for mating with queens diminishes by mid August se we stop grafting in late July.
Hi Tracy The cup is empty. It is polished by the bees in the cell builder for 24 hrs but they don't add royal jelly. We don't add royal jelly either so this is called a 'dry graft'.
I inherited the scope we use and it doesn't seem to be available now.This link is to a new microscope that we have started using: www.amscope.com/catalogsearch/result/?q=gooseneck+binocular
Not sure if a glitch or not but looked like one larvae fell out of the cup around the 3:55 mark when inserting the cups into frame! Seemed pretty large tho so maybe some old comb lol
@@UoGHoneyBeeResearchCentre I figured as much. Going to try grafting this year with queenless splits as well so learning as much as possible. Love the depth and info in all your videos! Keep making them!
Hi Petra I'd like to answer your question but I'm not sure what you mean by after 16 days. We don't cage the cells, we introduce them at ten days from grafting to full size splits ( see double nucs videos) or to mini nucs (see making mini nucs video) Thanks Petra.
UoG Honey Bee Research Centre i understand. So you take the capped queen cells out before they hatch and let them hatch in a nuc? My dad used to graft back in the 70. He put a queen cage around the cell and let them hatch in the brooder hive. I am wondering now what he did with so many undated queens.....
Hi Petra Yes we let the queens emerge in the nucs or splits. We get better acceptance with queen cells compared to virgin queens. Your dad probably had a good reason to do it his way.
First rule of beekeeping is there are no hard rules. Your Dad just used an older (but still pretty common method) that is a little more work but not as time sensitive. If your late coming back say 11 days instead of 10 or one hatched a little early she will go sting the others in their cells, and kill them. So one method adds some more work for a little insurance should life get in the way.
You mention that you play music to help you stay relaxed while you graft. Have you ever tried playing music around the hives? I ask because you are a research facility (right?). While nothing scientific, I have seen music influence dogs and cats to varying degrees, and wondered if there was any type of music that help to: calm bees; increase honey production; increase brood production; provoke hostile behavior; etc.
Hi TK Good question. I've never noticed any change in behaviour when listening to music in the bee yard. They don't have ears but are sensitive to vibrations.
@@UoGHoneyBeeResearchCentre Now my curiosity is piqued. I'm thinking the sound of a calm Brook, at low to moderate volume, near a hive with uncharacteristically testy bees. Hmmmmm
Hi Maxbees Nicot systems work well for some but I prefer to graft. It gives me more flexibility to graft from an number of breeder colonies and I get more consistent results. It's been a long time since I tried Jenter and Nicot but I found that I couldn't get all the queens to lay at a precise time so it was hard to work on a schedule.
Lol thank you. You guys do real professional work! Anyone can tell the dedication , love, and pride you all have in your work. Keep doing you. Question : how do you feel about harvesting royal jelly? N what does it taste like.
UoG Honey Bee Research Centre thanks for answering. I've since seen a few videos from I guess somewhere in Asia where they harvest royal jelly. I've been seriously thinking (for a few months now), about staring my first hive next year. I would like to get a flow hive hybrid. That one has 3 flow frames n 4 reg frames. What kind of,hive do you recommend , I would like to spend the least amount since it would be my first, I live right outside of Philly, pa. So I'm just wondering if some are better than others for winter. Thanks for,your time!
Camera man needs to practice his zoom. Or UA-cam's being funny on its picture quality. Other than that these videos have taken me from knowing nothing of beekeeping to feeling like I could raise bees

Hi paul what is the right age of the larvae for grafting and what is issue if we graft old larvae
Thank you for the videos. What does a appropriate aged larva look like?
Hi Cliff
Comma shaped and slightly larger than an egg. You can see one at 3:05 minutes on the video.
Very well explained. Thank you. And you get the Queen cups from the hives you inspect?
Thank you for the video. Have you used additional royal jelly, adding it to the cell to prevent it from desicating and promoting the larva's health?
Hi There
We transfer royal jelly with the larvae so there is no need to add more.
The tool we use picks up both royal jelly and the larvae. Thanks.
Hello, I saw the video and I liked it. I want to enter this beautiful experience to work with you

@@UoGHoneyBeeResearchCentre OK thanks, I'm hoping to try it in future
Do you only take larva out when they have the royal jelly? Or do all the larva have it??? Kinda new to this.
They all have some royal jelly. If conditions are great you have more royal jelly and grafting is easier.

@@UoGHoneyBeeResearchCentre Thanks for the great videos. What diameter are the wax cups?
Rick
3.52 did you lose a larva in 4th pod from the left?
What month do you usually start your first graft? And about when is it getting to late in the year to do it?
We start to graft in early May -about when dandelions start to bloom. Our drone supply for mating with queens diminishes by mid August se we stop grafting in late July.
UoG Honey Bee Research Centre so basically when drones start showing up is when it’s ok to start grafting?
when you transferred the larvae into the cup, what was in the cup. I know they shine the cups but do they also put royal jelly also?
Hi Tracy
The cup is empty. It is polished by the bees in the cell builder for 24 hrs but they don't add royal jelly. We don't add royal jelly either so this is called a 'dry graft'.

Is it necessary to prime the queen cups before grafting with wax?
Hi Noah
We don't prime the cups. Using the Chinese grafting tool allows you to transfer both the larvae and the royal jelly it is sitting in.
Thank you. Your videos are such a nice resource.

Hello.Write the brand, and the model of the microscope as Professor Paul Keli.
Thank you,

Why do you put a damp cloth on the frame?
It keeps the larvae from drying out. They would die if they get too dry.
Veery good
