    Pollen preferences of honeybees was analyzed in the blooming period of GörükleBursa, Turkey. Pollen loads were collected from the hives that belong to Apis mellifera anatoliaca, local honeybee subspecies in the region. Pollen grains of 47 taxa were identified (including unidentified), of which 11 of them reached the percentages higher than 1 % and 0,18 % of the total could not have been identified. Dominant taxa are; Helianthus annuus L. (34.84 %), Trifolium pratense L. (15.96 %), Cruciferae (15.34 %), Paliurus spina-christi Mill. (6.79 %), Rosaceae (6.44 %), Papaver spp. (6.12 %), Compositae (3.12 %), Punica granatum L. (1.59 %), Melilotus spp. (1.28 %), Trifolium repens L. (1.06 %), Zea mays L. (1.02 %) and these are representing 93.56 % of the total.

    Extraordinary colony losses have been reported in early 2007 from several eastern provinces of Turkey. We have conducted a questionnaire study on a subsample of beekeepers from Turkey. This is the first report on 80 questionnaires representing over 10,000 colonies. We investigated whether there has been extraordinary winter losses in comparison to previous years through pairwise analysis of self-reported past and present losses of same beekeepers. This analysis indicated regional extraordinary bee losses. In addition we have analyzed a battery of 9 question groups to investigate several hypotheses related to causes of bee deaths. These hypotheses included; irregular season, known bee diseases, colony collapse disorder, honey bee genetic source, use of different beekeeping inputs such as sugar feed, wax foundation, queens, and parasite and disease treatments. The results support hypotheses related to irregular season and an unknown regional factor.
