Previous data from this laboratory has shown that consumption of ethanol by worker honey bees disrupts learning, communication and social behaviours. We extend our honey bee model of ethanol induced behaviour by reporting preliminary observations on a queen honey bee (Apis mellifera anatoliaca Maa) which had consumed 20µl of a 10%, 2.0 M ethanol so...
The study was conducted during 2004-06 to determine the effects of pollination using honeybees on seed yield and quality characteristics of the rapeseed 'Pulsar' winter variety of canola (Brassica napus ssp. oleifera) was grown and small colonies of honeybee (Apis mellifera anatoliaca) were placed in mini hives with or without pollen trap. The pres...
Experiments utilized three honeybee subspecies from very distinct biomes (Apis mellifera caucasica, A.m. carnica, A.m. syriaca). In experiment one a simple association between odor and a sucrose feeding was readily established in all three subspecies. This association decreased when the conditioned stimulus was no longer followed by a feeding. Neit...
Pollen collected by honeybees foraging in the region of Bursa, Turkey was analysed for a whole year. Pollen loads were collected from the hives of Apis mellifera anatoliaca once a week and were classified by colour. Forty‐one taxa were identified from the pollen analyses of the loads and 14 of these had percentages higher than 1%. Only 2.05% of the...
The mite formerly known as Varroa jacobsoni is one of the major problems in beekeeping worldwide. Recently, it was shown that this pest is not V. jacobsoni, which chiefly infests the nests of Apis cerana in the Malaysia-Indonesia region, and the widespread pest was recognized with the new name, V. destructor. Morphometric analysis was performed on...

examined. Forty ou...
Pollen traps, in conjunction with walnut leaf smoke or mint leaves, were tested as a control for Varroa destructor. Experimental colonies were left untreated for one year prior to use in this study. Four treatment groups were tested: I - walnut smoke+pollen trap, II - paper smoke+pollen trap, III - walnut smoke only, and IV - mint leaves+pollen tra...
Notes and comments that the presence of queen cells in a colony does not necessarily indicate a queen change will occur. The presence of queen cells and cells which appear to have emerged are used in beekeeping to signal a need for actions to prevent swarming or to replace a failing queen with a queen of a desired stock rather than allow the colony...
This is the first extensive study of the incidence of varroa (Varroa destructor) and tracheal mites (Acarapis woodi) in Turkish honey bees (Apis mellifera). Samples were taken from 204 colonies in 39 apiaries spread over five regions of Turkey. Fifty bees from each colony were dissected in the laboratory and examined under stereo and compound micro...

We compared the European honeybee races Apis mellifera armeniaca, A.m. caucasica, A.m. cypria, and A.m. syriaca. These subspecies are endemic to very different habitats. Additionally, they are exposed to very different levels of predation. A.m. caucasica exists where honeybee predators typically are rare, while the remaining subspecies have ranges...
Honeybees can use various kinds of information, including color and pattern, in choosing flowers during foraging. We offered free-flying bees a dimorphic artificial patch of radial and bilateral blue/white flowers in order to examine three hypotheses to explain the noted increase in visitation to the flower type offering a lower caloric reward, i.e...
Differences in predation pressure and floral resources exist among the endemic ranges of Apis mellifera subspecies. Those environmental differences should select for heterogeneity in forager flower fidelity among honey bee subspecies, particularly when reward frequency differences are associated with competing flower types. We tested that evolution...
The foraging ecology of Apis mellifera syriaca and A. m. armeniaca was studied using artificial flower patches consisting of blue, white, and yellow flowers. Two experiments were performed with each race. Experiment I examined forager response to differences in sucrose reward molarity (quality of reward) associated with flower colors. Experiment II...
The foraging of Apis mellifera caucasica was examined on trimorphic (blue, yellow, white) artificial flower patches in the eastern region of the Black Sea. Foraging was defined by a superstructure where some bees visited only yellow flowers, and other bees limited visitation to blue and white flowers. That flower fidelity persisted in spite of rewa...
