COLOSS Questionnaires were disseminated during 2015 to estimate the colony losses inSpain. The dissemination of the questionnaires was made by asking collaboration trough beekeepers associations and during meetings. Also, some beekeepers were contacted by phone and asked to answer the questionnaire that the interviewer was filling out.
As in previous years, a low participation was achieved and only 86 beekeepers answered the questionnaire. This represented just 0.3% of participation according to the number of beekeepers inSpain. The colony mortality rate was 13.19% and the most of beekeepers declared there were no bees inside the colony (69.1% of lost colonies). Additionally, the 34.3% of the colonies were declared to be weak after winter. Conversely, only the 1.6% of the colonies were declared to have queen problems. Transhumance was an activity declared by the 29.5% of the participant beekeepers and the most of them did not have a significant flow on oil seed rape or maize (>70% in both cases). All beekeepers reported to treat against Varroa following the sanitary rules in the Country and the most used treatments were coumaphos and amitraz strips.
New methods to improve the dissemination of the questionnaire should be developed to increase the number of beekeepers collaborating in this survey.
