“…The differential morphometric traits mentioned above are probably attributable to royal jelly, the exclusive food of queen bees. Our former study revealed not only lower levels of fatty acids including 10-hydroxy-2-decenoic acid (10-HDA) in royal jelly but also reduced royal jelly amount per queen cell with the rise from 64 to 320 queen cells per colony [24]. To date, the role of 10-HDA in honey bee development and caste determination has been explored.…”

“…This is reflected in the higher larval acceptance rate and royal jelly provisioning in RJBs than in other honey bee races during royal jelly production [21][22][23]. Notably, the larval acceptance rate is over 90% even with 320 queen cells per colony [24]. The remarkable performance of RJBs makes it possible to rapidly rear a large number of queens.…”

“…The remarkable performance of RJBs makes it possible to rapidly rear a large number of queens. It should be noted, however, that the introduction of 320 queen cells could lower the royal jelly quantity and alter its chemical constituent levels compared to the introduction of 64 queen cells [24]. It is yet unknown whether these changes could influence the quality of the reared queens.…”

The mass rearing of high-quality queen bees is an essential beekeeping practice for producing new queens to maintain colony productivity. A strain of high royal-jelly-producing bees (RJBs; Apis mellifera ligustica) in China exhibits high potential for the rapid mass rearing of queens. To explore the potential changes in the quality of mass-reared queens, a set of morphometric traits and the sealed brood area were compared between the queens reared from 64 and 320 queen cells in RJB colonies. The increase in the queen cell number was found to induce a slightly but significantly reduced body weight and smaller wing length and thorax width in the reared queens at emergence. However, the ovariole number and sealed brood area, an indicator of the queen fecundity, were not observed to be significantly influenced. With respect to body weight and ovariole number, all the reared queens satisfied the current criteria for high-quality queens. Our findings provide evidence for the efficient mass production of high-quality queens using RJB colonies.

“…It is known that 350 tons of RJ are produced annually in China. This production is about 90 % of the world‘s RJ production [6,7] . Although there isn't official data, according to research, nearly 1 ton of RJ is produced in Türkiye, it has not been able to take advantage of the large RJ market [8] .…”

This study analysed some physicochemical and quality parameters of 176 royal jelly (RJ) samples from different regions of Türkiye, collected over different years and seasons. According to the obtained results, the moisture percentage varied between 47.36% and 69.58%, with no statistically significant differences seen across various seasons and areas (p>0.05). The average value of 10‐hydroxy‐2‐decenoic acid (10‐HDA), which varies according to factors such as season, region, and year, was determined to be 2.32%. It was also seen that this value was close to the international standard. The values of total acidity ranged from 28–58 mL 1N NaOH/100 g. Furthermore, statistical significance (p<0.001) was observed for the year‐region interaction in relation to 10‐HDA and total acidity. The pH measurement results for all samples confirmed the acidic nature of the samples and resulted in a range between 3.45 and 3.80. And the pH variability was also found to be statistically significant for years (p=0.002) and regions (p=0.011). Finally, the correlation analysis between moisture (%), 10‐HDA (%), total acidity, and pH revealed no statistically significant or strong differences. This comprehensive study, supported by statistical analyses, is thought to be a useful reference for future research on RJ.
