Abstract v~summary Royal Jelly IS the hypopharyngeal glandular and mandbular glands secretion of young workers, that is placed in queen cells as food for larval queens. In this experiment for Royal Jelly production, the results indicated that, the following points: 1~ For studying the effect of larval age during the grafted queen-cupS on the acceptance of queen cells indicated that, the larvae grafted at 12 h. old was the best, the mean average was 29.81 queen cells out of 45 queen cups grafted, followed with larvae grafted at 36 h. old; the acceptance was 30.45 queen cells. The amount of royal jelly produced under the different age of larvae showed that, the grafting of larvae at 12 h.old produced 5.65 g1colony royal jelly, it was more than that produced when larvae grafted at 36 h. which produced amount of 4.59 glcolony royal jelly. The amount of royal jelly produced per queen ce.ll was more than in case of larvae grafted at 12 h. it was 0.189 g while the amount of royal jelly produced in queen-cupS grafted with larvae at 36 h. was 0.149 glqueen cell. -_.------ --- Sununery 2- Effect of the time collection of royal jelly on the amount of produced. Showed that the acceptance of queen cells when RJ produced under different periods from grafting was 29.75 queen cell/colony in case the collection at 48 h., while the collection on 72 h.,the mean acceptance numbers was 28.94 queen cells /colony, this difference was not significant while the differences between the amounts of royal jelly produced at these times was highly significant, the collected of royal jelly at 72 h. was 4.9 g1colony mor than that produced when collected at 48 h. it give the mean average was 3.97 g1colony. The amount of royal jelly produced per queen cell was 0.169 g1queen cell in case of the collection at 72 h. it was more than of the collected at 48 h. was give average amount 0.136 glcell, differences were highly sificant. 3- Different types of hives was used to obtain their effect on royal jelly production. The number of queen acceptance was higher in swann box (38.11 queen cells/colony); followed by normal hive (32.44 queen cell/colony) and was (23.11 queencell/ colony) in case of double~queen~hive. The quantity of royal jelly produced in case of swann box was 6.83 glcolony followed by the normal hive with average of 5.5 glcolony, while in case of the double queen hive was 4.61 g1colony, this difference was highly significant. - 99- ------------------- Summery The amount of royal jelly produced per a queen-cell was 0.202 glqueen cell, in case of double queen hive, Followed by the swarm box with mean average amount was 0.179 g/queen cell, the amount of royal jelly produced per a queen-cell was 0.172 g/queen cell in case of normal hive. 4- Effect of artificialfeeding on the royal jelly production was studies, the results obtained showed that, the number of queen cells accepted was 34.77 in case of Brewer’s yeast feeding, it was more than that feeding on sugar syrup (31.55 queen cells/colony), and also in case of the control without artificial feeding which give the average about 29.66 queencells/ colony (out of 45 queen-cups that have been grafted per colony). The amount of royal jelly produced in case feeding the colonies on Brewer yeast was 6.64 g/colony; it was more than that produced in case of sugar syrup(4.9 g/colony),whileit was 3.65 g1colonyin case of the colonies without feeding as control, this difference was highly significant. The amount of royal jelly produced per a queen cell was 0.191 glqueen cell in case of the colonies feeding on Brewer’s yeast, it was more than that produced in case of co.lonies feeding on suger syrup (0.155 glqueen cell) and in case of the control; the amount of royal jelly per a queen cell was O.l27g, this difference was highly significant. -100 - --~---_.- -------------. Summery 5- Effect of queen-cupS types on the royal jelly production, the results obtained that, the difference between wax-queencups and rubber-queen cups was not significant difference, the acceptance of queen-cups was 29.00 and 28.87 queen cells/colony in case of rubber and wax queen-cupS respectively. The amount of royal jelly produced was 5.24 glcolony in case of rubber-cupS, while it was 4.65 g1colony in case of bees wax queen-cups, this difference was not significant. The amount of royal jelly produced per a queen cell was 0.183 glqueen cell in case of rubber-cups ,while it was 0.163 g1queen cell in case of wax-cups, this difference was highly significant. 6- Effect of types of honeybee races on the royal jelly production the results showed that, the acceptance of queen cells was 33.81 queen cells/colony in case of F Carnio1an, it was mor than that F1 Italin (33.06 queen ceWcolony, and also in case of the Fl Caucasion the average 35.5 queen-cell/colony. (out of 45 queen-cupS that have been grafted per colony), the different was not significant. The amount of royal jelly produced in case .of F1 Carniolan bees was 6.1 g/colony, while, in case ofFl Italian bees the mean average was 5.3 g1colony. In case of F1 Caucasion bees the mean average was 5.1 glcolony. -101- ~--_._---- - ---- - - - - -------- Summery This difference was not sigificant. The amount of royal jelly produced per a queen cell in case of Fl Carniolan bees with the mean average was 0.183 gIqueen cell. In case of F 1 Italian bees, The amount of royal jelly produced per a queen cell was, 0.169 g1queen cell. While, the amount of royal jelly produced per queen cell in case Fl caucasion bees was, 146 g/queen cell. The differences between the three strains were highly sinificance difference. 7_ Effect of seasonal activity of honeybee· colony on royal jelly production. The mean amounts of royal jelly produced per month were 3.84, 4.01, 4.25, 5.49, 5.76,4.19,5.09,6.18,4.49,4.12,3.71, and 2.76 g1colony from January to December, 1992. from the above results, the data indicated that, the statistical analysis was highly significance. The amount of royal jelly was higher in August {6.18), followed by May (5.76), April (5.49), July (5.09), September.
