Abstract The performance of bee colonies greatly depends on the quality of the queens. The current research was conducted at the apiary of the Faculty of Agriculture, Zanjan University, in Zanjan, Iran. Together, 24 rearing colonies were assigned to 4 grafting larvae age groups: 1-day-old, 2-day-old, 3-day-old, and emergency queens. Two feeding groups, fed and not fed, were created. The effects of reared queens on biological characteristics and performance of honeybee colonies (Apis mellifera meda) headed by those queens were measured. Age of grafted larvae significantly influenced the results. The performance ratios of the most efficient colonies headed by queens reared from 1-day-old larvae compared with the least-efficient queens reared from 3-day-old larvae were 118% in brood production, 140% in bee population, and 154% in honey production. However, the age of grafted larvae did not affect colony defense behavior. Supplemental feeding of rearing colonies increased brood production to 111%, bee population to 116%, and honey production to 115%. A combination of the effect of age of larvae and supplemental feeding resulted in twice as much honey (12 kg) produced by colonies with queens reared from 1-day-old larvae in fed rearing colonies compared to those with queens raised from 3-day-old larvae in unfed rearing colonies.

Effects of the Age of Grafted Larvae and the Effects of Supplemental Feeding on Some Morphological Characteristics of Iranian Queen Honey Bees (Apis mellifera medaSkorikov, 1929)The research was conducted at the apiary of the Faculty of Agriculture, Zanjan University in Zanjan, Iran. Queens were reared in 24Apis mellifera medahoney bee rearing colonies. The colonies were assigned to 4 grafting larvae age groups; 1 day old larvae, 2 day old larvae, and 3 day old larvae, and the last group reared emergency queen cells. The groups were divided into the 2 feeding groups: fed additionally and no fed. The effects of the age of the grafted larvae and the effects of supplemental feeding on 9 morphological characteristics of queens were measured. The results showed that the age of the larvae significantly affected the morphological characteristics of reared queens, and thus, their quality. Queens reared from 1 day old larvae were of the highest quality. These queens were significantly heavier (158.83 mg) and had significantly larger spermatheca (0.99 mm3) than queens reared from larvae 2 and 3 days old. Queens from emergency queen cells were of lower quality than queens reared from 1 day old larvae. However, queens from emergency queen cells were of higher quality than queens reared from 3 day old larvae. The supplemental feeding significantly increased most morphological characteristics of the reared queens. The different ages of the larvae did not significantly affect the wing length nor did supplemental feeding affect the wing length.

Although kin selection is commonly regarded as a major force in the evolution and maintenance of social behaviour in eusocial insects, recent controversy regarding whether honey bee (Apis mellifera L., 1758) workers can discriminate close kin from more distant relatives casts doubt on the extent to which cooperation among individuals within honey bee colonies is controlled by genetic relatedness. We contrasted brood and honey production in colonies where we diluted worker relatedness with those elements of productivity in colonies where relatedness was unmanipulated. Relatedness manipulation did not affect overall brood production, worker or drone brood production, the worker to drone brood sex ratio, or the volume of honey produced. Thus, there is no evidence that honey bees discriminate close from distant relatives or, more importantly, that dilution of the coefficient of relatedness within a colony has any impact on the efficiency of that colony.

Bee Colonies

The basic rule in honeybee (Apis mellifera L.) rearing is to work with qualified queens. Quality queen means strong and healthy colonies. Honey bee colonies are a social community, each managed by a single queen bee. The queen bee is the only female that produces eggs in the colony under normal conditions, and the quality and healthy queen is important for the continuity of the colony. Many factors affect the quality of the queen bee, such as the rearing colony, the age of the transferred larva and the transfer medium, the season, cell emergence weight, spermatheca charged, the characteristics of the starter and finisher hives. In this paper, the issues to be considered in raising a quality queen are emphasized.

Bee Colonies

Honeybees can only live and work in a bee colony. There is normally only one queen bee in a standard bee colony. It is the family's only fully matured female and the mother of young queen, drone, and worker bees. When a bee colony loses its queen bee and is unable to reproduce a new one, it eventually dies. Timely change of queen bees every 2 years, as well as increasing and maintaining the strength of bee colonies are the main zootechnical measures to maintain optimal life of bees and get the maximum amount of products from them. The presence of the queen bee in the bee family of honey bees fully influences their flight activity in collecting bee pollen. In its absence, the harvesting of pollen and its processing, as well as the extraction of wax and the construction of honeycombs, the cultivation of brood, and the collection of nectar are significantly slowed down and then completely stopped. With the advent of the uterus, all the functions of the family as a whole biological system are restored. Therefore, the quality of queens is a determining factor in the viability and productivity of the bee colony. The aim of the study was to compare the quality of reproductive function of queen bees of Apis mellifera sossimai and Apis mellifera carpatica breeds in different ways of obtaining them, and the impact on productivity of the bee colony. To carry out experimental work in the apiary, three control groups and two experimental groups were formed, with nine bee colonies in each group. In the first group, the queen bees were artificially breeded from the nursery, in the second group - fistulous queens bees, and in the third - the swarm queen bees. The apiary is situated on a 50-50 meter plot of land. Hives are used to keep bee colonies. Bees are kept in the apiary of the Ukrainian field breed. A pollinating honey area is available at the apiary. A winter house, a mobile vehicle, and a suitable chamber for honey pumping are all available at the apiary. Mustard is sown around the apiary every year. According to the study, big full-fledged queen bees are born in a healthy, physiologically complete bee colony. When the strength of a bee colony was increased, the queen bees were born 30 mg lighter. The number of fallopian tubes of queen bees raised with a biological integrity breach is 185,1 ± 7,3, while the number of fallopian tubes of queen bees raised with biological integrity is 207,6 ± 7,4. If the bees bring nectar and pollen during the breeding process, the queen bees are born huge, but without the forage а little and with poor executive abilities. It makes no difference how strong the foraging is; even 200 – 300 g of nectar and pollen per day has a positive impact on the quality of queen bees produced. Fistula uteruses had higher egg production compared to swarms in the same conditions of colony development.

The aim of this research was to analyze the relationship among hygienic behavior (HB), Varroa destructor infestation, and honey production in the central highlands of Ecuador. Overall, 75 honey bee colonies were evaluated before, during, and after production at three altitude levels (2600–2800, 2801–3000, and >3000 m.a.s.l.). The hygienic behavior percentage of the colonies was determined by the pin-killing method, and the colonies were classified into three groups: high HB (>85%), mid HB (60.1–85%), and low HB (≤60%). Varroa infestation was diagnosed as well, and honey production was evaluated only during production. HB was high and heterogeneous, averaging 80% ± 9.7%. Its highest expression was observed at lower altitudes. The infestation degree was low (3.47% ± 1.56%), although the mite was detected in all colonies upon sampling. A negative correlation was observed between HB and Varroa infestation in the first sampling (−0.49 **), suggesting that the high- and mid-altitude HB colonies underwent the lowest infestation rates, regardless of sampling. The correlations between HB and production were significant (0.26 *), indicating a positive effect of HB on production, meaning that colonies with high HB obtained the highest honey production (25.08 ± 4.82 kg/hive). The HB of bees showed an inverse relationship with altitude and it tended to reduce the effect of Varroa infestation, favoring honey production and, thus, suggesting the feasibility of selecting colonies with high HB.

This study during the spring of 2014, effects of plant extract and oil mixture obtained from various plants added to the syrup given to the forces equalized bee on physiological characteristics of the colonies were examined. Bee colonies (10 colonies in each group) were randomly divided into two groups. When the first group feed syrup and plant extract oil mixture, at the same rate with feed syrup only test group to control group (1/1 sucrose-water) was applied. According to the research results, the plant extract-oil mixture was not effective on the number of frames and hive weight. The mixture although numerically increased the amount of brood rearing area, this effect was not statistically significant. However, provided statistically significant increase in honey production. We concluded that, while the plant extract-oil mixture tested is not effective in brood production, is effective on honey production.
