[QUOTE="tristan, post: 12307, member: 30"] [IMG]https://www.landcareresearch.co.nz/assets/Discover-Our-Research/Environment/Sustainable-society-policy/NZ-Colony-Loss/2022-survey/9_pie_colony_loss_colonies__ScaleWidthWzEwMjRd.png[/IMG] what needs to be corrected here is the fique for wasps and unsure. hives rarely die from wasps, typically wasps get blamed because they are robbing out a nearly dead hive. you can see that by the low numbers of wasp related deaths in commercials but higher in the hobby side. so realistically we are looking at around 4% death by wasps. the rest is most likely varroa related so we can bump varroa fique up. the unsure deaths are also most likely varroa related. so for 1-10 colonies varroa should be around 38%, 11-50 varroa 37%, 51-250 varroa 37%, 251-500 varroa 31%, 501-3000 varroa 44% 3001+ varroa 45%. so what interesting here is the big outfits are reporting a lot larger varroa problems. the higher wasps reported of the 3001+ can indicate more of a staffing issue may be at play.
