[QUOTE="John B, post: 12299, member: 207"] I am a fan of the survey and am always happy to participate. It is really important to understand how trends are going. The only problem I have with the survey is that it is for winter losses which up till a few years ago wasn't a problem but the truly horrendous losses over the last three or four years have been in autumn. These are 100% varoa related but very poorly understood. Some is obviously resistance but in other cases the varoa die like they should with treatment but the hives just keep on dying anyway. Apart from being killed by wasps winter losses were very low around here in the pre-varoa days with just the odd failed Queen. Queens also don't last as long these days and fail far more frequently and throughout the year. [/QUOTE]
