Erdoğan, Yaşar
Numerous flowering plants rely on bees for pollination. Any natural or anthropogenic factor that threatens colony survival can have a large impact on plant production. This study investigates the effects of manmade hives built from different materials and how these may influence colony growth. Ten each of three hive types were selected, wooden, polystyrene and composite insulated hives. Factors of adult bee numbers, brood development, nectar flow period weight gain, bee flight activity, aggression response, and honey yield were selected markers of hive development. Statistically, each hive type produced significant variation (p<.05). The greatest overall productivity across all factors was for insulated hives made of composite material, with honey production approximately 35% times that of wood, 14% times that of polystyrene and in terms of the development of honeybee colonies, the average of other hives is 10.2 times.Highlights Relative humidity and temperature are important environmental factors for honeybees. Insulated hives, increased honey yield. High temperature and humidity inside the hive made honeybees more aggressive.

Erdoğan, Yaşar
This study was conducted in 2018 in order to determine the effects of an electric fence system on honeybee colonies housed in hives made from different materials. The experiment was carried out with honeybee colonies of 36 Caucasian races (Apis mellifera Caucasica) in full-size Langstroth hive. In terms of mean values of the aggressive behaviour of honeybee colonies were found to be the highest (13.57 number/colony) application group where the conductor wires of electric fence system are within a 1 m distance from hives and the lowest (2.39 number/colony) were obtained from control application group. The highest mean values adult bee development (23.76 ± 12.34 number/colony), development of brood area (5421.25 ± 1432.75 cm 2 /colony), nectar flow period weight gain (46.42 ± 3.61 kg/colony), flight activity (107.38 ± 11.74 number/colony) and honey yield (21.55 ± 1.54 kg/colony) were determined in control groups. When the average values of honeybees robbing behaviour were examined, the highest value (3.33 ± 0.32 number/colony) was determined in the control groups. This experiment shows that the electromagnetic and electric fields produced by the electric fence system have negative effects on honeybees. In order to minimise the negative effects of the electric fence system on the bees, hives should be covered with a metal screen or should be placed long distance (minimum 2 m) from the electric fences.Highlights The electric fence system is the most effective method of keeping honeybee colonies. At the same time, the electric fence system disturbs the honeybees. All negativity can be completely eliminated by simple measures.

In this study, wintering ability and some physiological properties of Buckfast, Carniolan, Caucasian and Erzurum honeybee genotypes were investigated in Eastern Anatolian conditions. During the wintering season of 2014, a total of 48 colonies, 12 from each of Buckfast, Carniolan, Caucasian and Erzurum honey bee genotypes, were taken from the equilibrated colonies of Langstroth type wooden hives for wintering. In the 2015 production period, a total of 43 colonies,11 from each of Buckfast, Carniolan, Erzurum genotypes and 10 from Caucasian genotype were used in the study. In the production season, the average number of combs covered with bees in genotype groups were found as 11.72±0.63, 12.17±0.62, 9.52±0.51 and 10.72±0.55 per colony, and the average brood areas were found as 2713.7±237.9, 2797.6±238.3, 2036.5±166.4, 2364.3±197.2 cm2/colony (19.04.2015-4.10.2015). The difference between the groups was found statistically significant (P<0.01) in terms of number of combs covered with bees and brood areas. Averarage honey yields were determined as 28.08±2.37, 29.94±2.17, 19.28±2.13 and 23.36±2.15 kg/colony, respectively. The difference between groups in honey yield was found statistically significant (P<0.05).
