Thanks for the report, Dennis. We're all interested in following the results of the various trials going on. I realise that there are many small special interest lists these days for various topics, but most of us don't have time to read them all and we appreciate when anyone posts a synopsis to BEE-L. A lot of the special interest groups have a high level of background chatter and a there is lot of reading to do before any real information is found, but they are interesting communities and some do have the time to spend there. I tend to spend some time reading them in the winter, but in the summer, time is short and I stick to BEE-L. From those who do spend the time to read these other lists, we would love to get a summary monthly or so. In reading through your note, I was wondering a number of things and perhaps you could expand a bit? > I had seen colonies on large cell comb collapse long before this stage.... > Lost about 40% of my small cell colonies throughout the winter. Are you running any or are all your hives on small cell? How small? How many hives went into winter? > I have not seen a single varroa mite on a bee or on drone brood this spring. Are you using any mite treatments? > considering the very cold, nasty spring weather we have had. Where do you live? Thanks allen http://www.internode.net/honeybee/diary/
