Royal jelly production with queens produced by single and double grafting in Africanized honeybee colonies Animal Sciences
Santos, Pedro Rosa; Souza, Tuan Henrique Smielevski de; Rossoni, Diogo Francisco; Toledo, Vagner de Alencar Arnaut de.
The objective of this research was to evaluate royal jelly production from Africanized honeybee queens of different lineages (lineage selected for honey production, lineage selected for royal jelly production and unselected) produced by single and double grafting and to compare royal jelly production among their offspring. Data were tested by double factorial analysis of variance and the means were compared by Tukey test at 5%. The parameters evaluated were: queen weight at emergence, percentage of larvae acceptance in the upper and lower bars, royal jelly per cup (mg) and royal jelly per colony/collection (g). Queens selected for honey presented greater weight at emergence, while the unselected queens were the lightest. Double grafting was better than...

Royal jelly production in Africanized colonies with selected queens, use of Chinese model cups and supplementation Animal Sciences
Pereira, Heber Luiz; Santos, Pedro da Rosa; Rossoni, Diogo Francisco; Toledo, Vagner de Alencar Arnaut de.
This research was carried out to evaluate the royal jelly production in two trials. In Trial I, three genotypes of Africanized honeybees (Apis mellifera L.) were submitted to royal jelly production with two types of cups of different size and volume (conventional and Chinese model) and two types of supplements (commercial and formulated). A total of 24 colonies were used, two bars with different cups each, alternating between the upper or lower position of the frame. While in Trial II, 18 colonies, two genotypes, two types of cups and two types of supplement were tested. The evaluated parameters were: percentage of larvae accepted in upper and lower bars, royal jelly per cup (mg), and royal jelly per colony/collection (g). Chinese cups were not well...
