Abstract
This experiment was done at a private apiary in Damietta region during the years (2017-2020), and accordingly the study was divided into two parts:
The First part:. The results during the two years of the study showed the acceptance rate of the grafted larvae was a significant difference when the number of larvae 32 from the 48, so increased in the middle from the edge as follows and agreed with that in the second year, the results also recorded very significant differences between The two periods of rearing, summer and late winter and a clear effect of the genetic origin of the Carniolan strain and the Bickfast (88.9%-80.6%). The first dimple on the middle and upper levels (89.6%-83.4%-81.3%),
The results recorded the average coverage ratio a small significant difference between the two numbers, while showed significant differences between the middle and adge bare positions and The interaction appeared between the breeding season and the number of bots, and the highest closure rate reached 97.8% in the classroom season, while in late winter 91.7%) and the genetic origin did not record significant effects on the coverage rate, but it interacted with the level of the mulch, and significant differences appeared between the two breeds and the level of the mulch, which was the highest closing rate. The highest (100%-97.7%) and the lowest (100%-93.8%)
Significant differences were found between the weights resulting from rearing 32 and 48, respectively. And the royal houses raised in the middle inside the brood nest gave heavier weights than the one on the edge Significantly in the weight of the bred virgins of the Carniolan strain and the Bickfast, respectively. The number 32 gave a shorter period (184 hours) than the number 48 (190.4 hours), and the houses bred in the middle inside the brood nest (183.7 hours) and recorded a significant difference during the two breeding seasons in the summer Compared to late winter, and the genetic origin and level of the sedge did not record clear effects, did not record any significant differences.
The second part: The effect of queens weight at hatching on their productive traits, This study was conducted over two years (2019-2020).The results recorded a significant moral difference in the group of heavier queens by weight compared to the light queens with a mating percentage for the two years in a row. The average start of egg laying for all queens varied from 6-14 days after spawning, and the heavier queens started laying eggs early.In general, the overall mean of the two open brood, sealed brood, total brood worker, and drone brood producing areas, number of building queen cups, stored pollen areas and stored honey areas in colonies containing heavier queens were higher than medium and light queens during the two years of the study.
