Effect of different grafting larvae genotype under cub's position and bar's level on acceptance percentages and royal jelly quantity mean

الملخص EN

Royal jelly is a yellowish-white, creamy, acidic secretion, with a slightly pungent odor and taste, produced by the hypopharyngeal and mandibular glands of worker honey bees [Apis mellifera L.

(Hymenoptera :Apidae)].

In this study, the effect of the different grafting larvae genotype under different cub's position and bar's level on the acceptance percentages mean and the royal jelly produced quantity mean were examined.

The fourth day is the first larval age (larvae of one day) which takes the shape of the crescent was used for grafting.

Two different grafting larvae genotype were used (Italian and Carniolan hybrids).

The Italian grafting larvae, middle bar and the medium cubs have the highest acceptance percentages mean more than the other treatments (71.3).

As the Italian grafting larvae, right cubs and the middle bar have the highest royal jelly quantity mean more than the other treatments (167.2).

For the best results of high acceptance percentage and the highest royal jelly quantity mean the Italian hybrid grafting larvae and were recommended.

As the middle bar should be used for the best results.
