“…Various biotic and abiotic factors affect the quantity and quality of RJ [ 25 – 28 ]. The most important factors are honey bee races [ 23 , 29 ], colony type, i.e., queen-less or queenright [ 30 ], transfer age of the larvae [ 31 ], number of transfer queen cell cup [ 30 , 32 ], grafting techniques [ 33 ], grafting bar level and queen cell position [ 34 , 35 ], harvesting interval [ 36 ], feeding source [ 37 – 39 ] and seasons [ 25 , 35 , 40 ]. For instance, when bees are fed on sugar syrup, it causes significant changes in the amount and structure of vital components of RJ such as amino acids, carbohydrates and vitamins [ 41 ].…”

Royal jelly (RJ) is an acidic yellowish-white secretion of worker honey bee glands, used as food material of worker bee larvae for the first three days and queen bee larvae for the entire life. It is commercially used in cosmetics and medicinal industry in various parts of the world. This study determined the queen cell acceptance rate and RJ production difference among Italian and Carniolan bee races. Furthermore, the effect of plastic cup cell priming media, diets and seasons were tested on the larval cell acceptance rate and RJ yield of both races. The results indicated that average queen cell acceptance rate was significantly (p<0.001) higher in Italian race (75.53 ± 1.41%) than Carniolan race (58.20 ± 1.30%). Similarly, mean RJ yield per colony significantly (p<0.001) differed between both bee races, which were 13.10 ± 0.42 g and 9.66 ± 0.43 g, in Italian and Carniolan races, respectively. Moreover, priming media, diets and seasons significantly (p<0.001) affected queen cell acceptance rate and RJ production of both bee races. This study would help breeders to select the bees with higher-level of queen cell acceptance rate and RJ production in the future.

“…The amount and quality of RJ production are affected by a variety of biotic and abiotic variables [ 30 ]. The most important among them are; honey bee races [ 28 , 31 ], whether the colony is queenless or queenright [ 32 ], larval age [ 33 ], types of queen cell cups [ 34 ], grafting methods [ 35 ], queen cell position on grafting bar [ 36 , 37 ], harvesting time [ 38 ], nutritional source [ 21 , 39 , 40 ], season and, also colony strength [ 37 , 41 ]. When bees feed sugar syrup, for example, the quantity and structure of essential RJ ingredients including amino acids, carbohydrates, and vitamins are significantly altered [ 42 ].…”

Honey bees are crucial for pollination services globally and produce important hive products including honey, royal jelly, pollen, and propolis that are being used commercially in food, cosmetics, and alternative medicinal purposes. Among the bee products, royal jelly (RJ) has long attracted scientists’ interest because of its importance in honey caste differentiation. The present research was carried out to determine the acceptance rate of queen cells, and RJ production between the hygienic and non-hygienic lines. Further, this study unveils the effect of pollen substitute diets on the queen cell acceptance rate and RJ yields between both bee stocks. Results showed that the uncapped brood cells and dead brood’s removal percentage was significantly more in hygienic bee colonies in comparison to non-hygienic bee colonies (p < 0.05). The average percentage of larval acceptance was statistically higher in hygienic lines (64.33 ± 2.91%) compared to non-hygienic lines (29.67 ± 1.20%). Similarly, the RJ mean weight per colony differed statistically between both bee stocks (p<0.001), which were 12.23 ± 0.52 g and 6.72 ± 0.33 g, respectively. Moreover, our results demonstrated that a significant difference was observed in larval acceptance rate, RJ yields (per colony and per cup) between both bee stocks those fed on various diets. However, no significant difference was recorded in RJ yields (per colony and per cup) between both bee stock that feeds on either commercially available pollen or pollen substitute. This study may provide future applications in helping bee breeders to choose the bees that carry a higher level of hygienic behavior with high RJ production traits.

The loss of honey bees has drawn a large amount of attention in various countries. Therefore, the development of efficient methods for recovering honey bee populations has been a priority for beekeepers. Here we present an extended literature review and report on personal communications relating to the characterization of the local and bred stock of honey bees in the Russian Federation. New types have been bred from local colonies (A. mellifera L., A. m. carpatica Avet., A. m. caucasia Gorb.). The main selection traits consist of a strong ability for overwintering, disease resistance and different aptitudes for nectar collection in low and high blooming seasons. These honey bees were certified by several methods: behavioral, morphometric and genetic analysis. We illustrate the practical experience of scientists, beekeepers and breeders in breeding A. mellifera Far East honey bees with Varroa and tracheal mite resistance, which were the initial reasons for breeding the A. mellifera Far Eastern breed by Russian breeders, Russian honey bee in America, the hybrid honey bee in Canada by American breeders, and in China by Chinese beekeepers. The recent achievements of Russian beekeepers may lead to the recovery of beekeeping areas suffering from crossbreeding and losses of honey bee colonies.
