Hi Stuart. We had CBPV in one of our hives last year. We first noticed this in July with exactly the same symptoms as you have shown and described in today's video. In September, we had multiple bee deaths outside the hive and called in our local bee inspector. He took some samples for the Newcastle research and noted that he had never seen the shaking so bad. It had been a very strong hive, 5 box hive (Rose method). He did acknowledge that there was no recognised treatment however he did suggest the following: we removed the hive from its stand and replaced with a new, clean, full box of capped honey from a healthy hive and on top of this, a box of foundation (everything was new, crown board, lid, floor, stand etc. We located the queen and placed her in the new hive and shook all of the bees 10 feet away from the hive onto a sheet with a ramp up to the new hive entrance. Eventually, all the healthy bees walked into the hive and were convinced they had swarmed and so went into overdrive and drew out the top box within the week, helped by a 1:1 sugar syrup. Obviously all the weaker bees did not make it back to the new hive, however we also feel that by making them think they swarmed perhaps galvanised them and fought off the disease. We shook the bees and made them walk on the 9th September. We do have a late honey flow here so this would have helped. The hive was unfortunately near to another hive. This also developed the virus but slightly later and so when it came to the later stages of the disease, it was mid September and the weather was not conducive to perform the 'walk'. We then had a direct comparison of the two hives throughout winter. Both hives we treated for varroa in January with Apibioxal. The death rate in the second hive was significant whereas the 'walked' hive was robust. Coming into this Spring, our 'walked' hive made a massive come back, this is with the original queen too. Our second hive just got through the winter however we lost the queen in April. We are keeping a careful watch on our hives this year and so far there has been no sign of the virus in any of the hives. Another option that was suggested was take the original hive up to 100 metres away and shake them on the ground. Therefore only the strongest flying bees would make it back to the hive. However due to being so late in the season, we took the 'walk' option instead. We don't regard this as a cure all, but it seemed to work very successfully in our case.

Hi Andy, Thank you so much for such a details comment. I'm moving the colony to an isolation apiary today and as a first step am going to try the "Shake and Walk" method. I will record a video to show what I am doing and give everyone an idea as to how the process is carried out and to show if it works. Stewart

Removed a feral colony from a friend's garage that had this virus. I re queened it and kept them isolated and fed and the numbers of "walking dead" started dwindling until the hive became fully healthy and grew into a second deep brood box. One of my strongest hives now.

Hi Stewart, we had a hive back in September with CBPV, it was spotted when we had a Bee inspector visit us, we were given two options, destroy the hive or relocate and place in isolation, we decided to relocate and the Bees improved dramatically, building up in numbers, unfortunately the hive died out in February after the cold snaps of weather, I must add that once isolated a few weeks later the number of dead Bees dramatically reduced

Then moving the hive every 3 days may be a good idea Getting ridd of the elder bees so reduce infection by older bees. I am suggesting this as a last resort. There may be a better methods. I would leave a dummy hive in place of the hive thats been moved and be prepared to feed. Hope you get a solution soon Regards John Owen

Hi Stuart. As always your videos are of great help. We spotted last year CBPV in a single hive that was fortunately separated from our main apiary. It was an incredibly busy and productive hive. We increased the brood size with a super and fed well, which took us into the winter. In the spring the hive was still alive and had no signs of CBPV, so we thought the problem was resolved. About a month ago we noticed queen cells had been produced and on careful inspection we thought we saw a few bees looking like they had CBPV. We left alone and within a week we saw that CBPV was back in earnest with many dead bees. The re-queening didn't work. The hive is now very small and sad. As CBPV is so devastating we have decided to lose the hive. The question is, what do we do with the brood, supers, boxes stand and frames? It would appear that freezing will not work. Will flaming? if you have any ideas on the reuse of kit, we would love to hear from you. Many thanks.

Just a suggestion for thought, relocate the hive and isolate ,after the hive has reoriented do the laying worker method of shacking the bees off all of the frames at a good distance from the hive( after U cage the queen) and study the results. I know that this theory doesn't work for that problem, but like I said just something to think about .Thanks for your videos.

I've learned a little about this and would like to share what I know here. It's the fecal matter that infects, and when other healthy bees attempt to get rid of it and clean the hive they are reinfected. So what I have heard will turn this around is get a brand new hive and set it in the same, or close, location. Cage the queen, and get rid of the entire old hive. The place a blanket far out away from the new hive and shake all the old bees. The non-infected will walk in, leaving all the infected behind. This give them a new hive, and new start, and has worked in where I learned about it.

Hi Stuart, I am one of those new beekeepers that started with one hive I caught a swarm at the beginning of May and noticed a few of these black greasy looking bees while catching this swarm. When setting up my hive I started with a queen separator between the base and bottom brood box I noticed after a few days that I had drones trying to enter the hive. Here is my crazy Siri I think it is the drones spreading viruses and mites. Curious to see if anyone else has tried this. They hive a still doing well. I have noticed a consistent number of black greasy bees. So far so good my bees are still growing strong. I say build an immunity to said virus. If they fail let it be nature. If nature does it’s thing and evolves then great.

Poor drones! Old foragers can look black and shiny and particularly those that rob other colonies can take on this appearance. Storch, 'At the Hive Entrance', describes this. Keeping viruses under control requires distancing, good nutrition, good housing and the chance to out-evolve - we all know this now in the COVID pandemic and ought to apply it to the bees.

Hi Pamela, There could just be a few bees that have died in their cells before emerging as adult bees and your colony is good at housekeeping (Hygenic bees). Unless you find lots of dead bees outside I wouldn't be too worried about it. If you start to find piles of bees outside check for Chronic Bee Paralysis Virus. Stewart

I have only just come across this CBPV myself and have some questions to prompt a discussion. If the varroa mite is the vector in the transmission of the DWVirus by sequentially sucking the young bees blood and transmitting it that way, is the varroa also the vector for CBPVirus and not just physical proximity (overcrowding). If overcrowding was the vector why do not all the bees catch it? Why does the queen not get it? What is different about her apart from the varroa not being tolerated on her? Why do some colonies survive and others do not? If there is anyone with any views or facts I would be pleased to hear them.

@fishmanfairclough75306 жыл бұрын
That seems unlikely as the virus particles are mainly in the mushroom bodies (infection mainly in the bee's brain) and so probably aren't transmitted through the sexual act, in terms of worse infection the drones probably aren't able to fly at that point to mate with the queen anyway. Would be interesting to see if the drones are infected at the same rate as the workers.

Hi D.B., That's a really interesting observation. Do you have any examples of why you think this is the case? Last Autumn was the first time I've used Apistan for a long time, over five years in fact, and it was pretty effective. I'm very cautious of a build up of resistance so I won't be using it again for at least 4-5 yrs. I am leaning towards just using Oxalic Acid treatments going forward. Stewart
