“…Other authors also found differences (HAYDAK, 1970;PALMA, 1992;SCHMIDT;BUCHMANN, 1992;LERCKER et al, 1993;SCHMITZOVA et al, 1998;PARFITT, 1999;GARCIA-AMOEDO;ALMEIDA-MURADIAN, 2007) and attributed these differences to the nutritional status of the evaluated colonies, age of mother queens, and the laboratory methods used to analyze their components. Queiroz, Barbosa and Azevedo (2001) reported that supplementation is good, mainly in the Northeast region of Brazil, for royal jelly production throughout the year, including autumn and winter, periods between flowering, in regions of monoculture such as sugarcane plantation, limited pollen flow or low nutritional pollen quality.…”

-In this study, the chemical and mineral composition and trace elements in royal jelly (RJ) and worker jelly (WJ) and in royal jelly on particular days (only-2-day RJ [O2d], only-3-day RJ [O3d] and only-4-day RJ [O4d]) were determined. Significant differences in levels of moisture, protein, 10-hydroxy-2-decenoic acid (10-HDA), fructose (F) and glucose (G) were found between the RJ and WJ samples. The nutrient content was significantly higher in samples on O2d than the O3d and O4d samples. The results of this study add to the current knowledge of the nutritional value of RJ and WJ. These results also imply a strong relationship between nutritional effects and polyphenism in honey bees.chemical / composition / royal jelly / worker jelly

“…The viscosity of royal jelly varies with the age of honeybees and water content. Royal jelly is widely known for its complex composition, including various minerals, proteins, amino acids, steroids, phenols, carbohydrates, vitamins, lipids, and other, as yet, unidentified substances (Garcia-Amoedo and Almeida-Muradian, 2007).…”

ABSTRACT.It is important to select the best honeybees that produce royal jelly to identify important molecular markers, such as major royal jelly proteins (MRJPs), and hence contribute to the development of new breeding strategies to improve the production of this substance. Therefore, this study focused on evaluating the genetic variability of mrjp3, mrjp5, and mrjp8 and associated allele maintenance during the process of selective reproduction in Africanized Apis mellifera individuals, which were chosen based on royal jelly production. The three loci analyzed were polymorphic, and produced a total of 16 alleles, with 4 new alleles, which were identified at mrjp5. The effective number of alleles at mrjp3 was 3.81. The observed average heterozygosity was 0.4905, indicating a high degree of genetic variability at these loci. The elevated F IS values for mrjp3, mrjp5, and mrjp8 (0.4188, 0.1077, and 0.2847, respectively) indicate an excess of homozygotes. The selection of Africanized A. mellifera queens for royal jelly production has maintained the mrjp3 C, D, and E alleles; although, the C allele occurred at a low frequency. The heterozygosity and F IS values show that the genetic variability of the queens is decreasing at the analyzed loci, generating an 6725 ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 13 (3): 6724-6733 (2014) MRJP marker for Africanized honeybees producing royal jelly excess of homozygotes. However, the large numbers of drones that fertilize the queens make it difficult to develop homozygotes at mrjp3. Mating through instrumental insemination using the drones of known genotypes is required to increase the efficiency of Africanized A. mellifera-breeding programs, and to improve the quality and efficiency of commercial royal jelly apiaries.
