difficult. Less concern for Varroa is also suggested by the high percentage of participants of this survey who have taken the individual decision not to use any chemical treatment, 85% i.e. 46 out of the total of 53 participants. Furthermore, the 41.3% losses sustained by participants treating, i.e. 31 losses out of 75 colonies, were higher than those choosing not to treat who had a 32.4% loss, i.e. 57 losses out of 176 colonies. The majority of participants in this survey keep bees in National hives, 173 out of the 251 total. The full detail of hives used and all the collated data from this survey is shown in the table. The table is divided into two, with the upper section showing the hives that were chemically treated for Varroa and the lower section the hives not treated for Varroa. Other than showing the wide variety of hives used it is difficult to draw clear conclusions comparing hive types because of the small numbers.

The meaning of ‘treated’ is less clear. Participants used a variety of different treatments as follows: thymol in Apiguard or crystals, Apistan, and/or oxalic acid. This survey is not rigorous scientific research. It is a survey to collate information from fellow local beekeepers to try and further our own knowledge about our bees and our own beekeeping, especially relating to ‘winter losses’.
