Colony condition and differences in individual preferences influence forage type collected by bees. Physiological bases for the changing preferences of individual foragers are just beginning to be examined. Recently, for honey bees octopamine is shown to influence age at onset of foraging and probability of dance for rewards. However, octopamine has not been causally linked with foraging preference in the field. We tested the hypothesis that changes in octoparnine may alter forage type (preference hypothesis). We treated identified foragers orally with octoparnine or its immediate precursor, tyramine, or sucrose syrup (control). Octopamine-treated foragers switched type of material collected, control bees did not. Tyramine group results were not different from the control group. In addition, sugar concentrations of nectar collected by foragers after octoparnine treatment were lower than before treatment, indicating change in preference. In contrast, before and after nectar concentrations for bees in the control group were similar. These results, taken together, support the preference hypothesis.

This chapter addresses survey methodology and questionnaire design for the collection of data pertaining to estimation of honey bee colony loss rates and identification of risk factors for colony loss. Sources of error in surveys are described. Advantages and disadvantages of different random and non-random sampling strategies and different modes of data collection are presented to enable the researcher to make an informed choice. We discuss survey and questionnaire methodology in some detail, for the purpo...
Genetic and morphometric variation in honeybee (Apis mellifera L.) populations of Turkey
Kandemir, I; Kence, M; Kence, Aykut (Springer Science and Business Media LLC, 2000-05-01)
Six enzyme systems were studied to determine the genetic variability in honeybee populations in Turkey. Ten morphometric characters were also measured to determine the extent of morphometric variation. Out of six enzyme systems, four were found to be polymorphic with 16 allozymes. The average heterozygosity was calculated as 0.072 +/- 0.007. Morphometric and electrophoretic variables were equally effective in discriminating honeybee populations. European and Anatolian honeybees were separated on the first a...

The changes in growth and photosynthetic performance of two wheat (Triticum aestivum L.) cultivars (Bolal-2973 and Atay-85) differing in their sensitivity to boron (B) toxicity were investigated under toxic B conditions. Eight-day old seedlings were exposed to highly toxic B concentrations (5, 7.5, and 10 mM H3BO3) for 5 and 9 days. Fast chlorophyll a fluorescence kinetics was determined and analysed using JIP test. Growth parameters, tissue B contents, and membrane damage were measured at two stress durati...
Morphometric and genetic variability of honey bee (Apis mellifera L.) populations from northern Iran
Kence, Meral; Farhoud, Houmen Jabbari; Tunca, Rahsan Ivgin (Informa UK Limited, 2009-01-01)
Samples from seven honey bee populations; five Apis mellifera meda from Iran and two from Turkey, one belonging to A. m. meda and one to A. m. caucasica, were investigated using morphometric, mtDNA, and microsatellite analyses. Morphometric analysis revealed three distinct clusters. The first included all Iranian populations, whilst the second and third contained the meda and caucasica bees from Turkey. No variation was observed in the DraI restriction of COI-COII intergenic region in mitochondrial DNA, yie...
Identification and characterization of hydrolytic enzymes from the midgut of Sunn Pest of wheat (Eurygaster integriceps)
Ogur, E.; YÜCEL, MUSTAFA; Öktem, Hüseyin Avni (Informa UK Limited, 2009-01-01)
To help in the development of Sunn Pest-resistant transgenic plants employing protease or alpha-amylase inhibitors, midgut hydrolytic enzymes of Sunn Pest (Eurygaster integriceps, Put.) (Heteroptera: Scutelleridae) were identified and characterized biochemically. We observed levels of very low proteolytic activity of trypsin (3 nmoles/min/mg), elastase (0.66 nmoles/min/mg) and leucine aminopeptidase-like (14.4 nmoles/min/mg) proteases, but no chymotrypsin and papain-like activity. Proteolytic activities wer...
