    landcruiser 70 series upgrades

    Before you remap and re clutch, maybe just a larger exhaust as a first step, it is suppose to make a big difference on the V8's, and won't put your warranty(if any) at risk. With 2 heavy pallets on the truck, and 4 on the trailer, you are only barely legal depending on how solid the boxes are- you can't carry more. My V8 underwhelms me at times, but it is still in another league compared to other utes.

    Queen with a freckle

    I would see those marks occasionally back in my yellow bee days- harder to see with carni's! Called them birthmarks, like John, thought maybe the origins were a sting, or maybe a knock to the cell when being transported. Would find them laying normally sometimes.

    Splitting hive mystery

    Probably 2 queens in the hive you split- mother and daughter most likely, happens more often than you think.

    Two Queen Questions

    I agree, never put attendants in any type of banking cage. The system works, but you lose varying percentages of the caged Queens, and I don't think they are all the ones that were better off dead any way, and I think mating percentages are lower in nucs where a Queen is being held. The JzBz cages work well for this, with a cell cup on the candy tube, and candy the cages as well- it keeps the Queens out of the tube.

    Chronic re invasion is a Myth?

    I stand corrected. That just appeared to be what happened when beekeepers brought mellifera alongside cerana. Without the genetic tools we have now, there was no way to distinguish the species. All that was known for sure was that jacobsoni could not reproduce on mellifera, and all of a sudden in 1960 it could, and a convenient explanation was the mutant jacobsoni, and that was accepted theory, until your modern genetic tools took all the fun out of it. If destructor has been around in cerana for millions of years, it did an amazing job of avoiding mellifera until 1960. So nothing until 1960, then virtual global distribution by 2000.

    Yes, Varroa destructor is a distinct species, but it originated as a mutant of Varroa jacobsoni less than 60 years ago. And yes, it was Dennis who finally solved the puzzle, and differentiated between the 2 species- we can almost claim him as an honorary Kiwi because he spent a lot of time working for DSIR at Mt. Albert during the 80's, and a bit into the 90's, and a lot of beekeepers came to know him well, and enjoy his company.

    Only using the Primorsky Bees as an example. I wouldn't want them here either. From my experience with them, I wasn't impressed with them at all, except for their Varroa tolerance. They were generally a bit nervous and nasty, but worst of all, they were so swarmy, and not very productive. Those negative traits are not necessarily linked to their Varroa tolerance, but with those bees they adapted to the environment they were in.

    Why would the importation of a small number of Varroa Tolerant European Honey Bees into a research Centre in Louisiana necessarily mean the clock is ticking towards totally tolerant bees stocks across America? For not millions, but more likely many 10's of thousands of years Varroa jacobsoni parasitised Apis cerana(the Asian Honey Bee). They evolved together, and Apis cerana were totally tolerant of Varroa j., Varroa j. could not reproduce on Apis mellifera, but last century(a mere blink-of-an-eye ago in evolutionary timescales) probably in Far East Russia where Apis mellifera was being kept along side Apis cerana, a mutation occurred, a mite resulted that could reproduce on Apis mellifera, Varroa destructor was born, and it spread around Apis mellifera populations around the world, arriving in NZ in April, 2000. Humans are not trying to reverse anything, but by treating, we are standing in the way of Apis mellifera adapting to this very new pest. As a beginner beekeeper, you should have an open mind, and a thirst for more knowledge about the bees you keep, and not enter so rabidly into discussions you know little about.

    I agree, do we ever want a feral population like, and of the size, we had here pre-varroa. Tolerant bees would see the inevitable return of the ferals much more quickly.

    Same year as we have world peace. What a stupid statement. Again great attitude.

    1997(no 2 in it), the year Rinderer first brought Primorsky Honey Bees to the U.S., after their research had shown that the Apis mellifera population there were tolerant of Varroa D., and could exist treatment free.

    Last century, Apis mellifera in the Primorsky region of Eastern Russia achieved it on their own when treatment free beekeeping was the only option, and in Western Europe breeding efforts resulted in some very varroa tolerant carnica bee stocks. This century, breeding efforts have continued and there are lots of examples of people beekeeping treatment free. As for NZ and with attitudes like yours- it will never happen.

    Of course there 'Aint nothing wrong with being a new entrant- we all were at some point. I already admitted I was a bit harsh, and sort of gave @Philbee a 'Bro hug', so let it go.

    I was a bit harsh with my post. Actually, I am a big fan of the work that you have been doing, and you should feel proud of your efforts to develop a more effective oxalic varroa treatment. BUT it is still only a varroa treatment, the final solution will be achieved through breeding for Varroa Tolerance. We just can't accept that our future is brood nests full of of staples stuffing up good brood comb! With time, as with any treatment , the staples will become less effective. We can't just sit back and accept that we only have a future with Varroa Treatments as our only option. Back to the inter-colony mobility of mites- I think they are a lot more mobile than we think. It is in their interest to be mobile, and their evolution would have saw to that.

    Yea, re invasion is a myth, just like Climate Change. Mites loading in from nearby, and not so nearby, collapsing and heavily infested colonies is what makes managing mites a challenge. If it was simply mite reproduction, then dealing with Varroa would be a piece of cake. You must not have been around in the early days, or you would not be asking such a question.
