| Abstract | ||||
| The present work was carried out at Fayoum governorate to study the effect of the genetic origin of breeding colonies (A.m. carnica, A.m. ligustica and A.m.bukfast) and rearing colonies (A. m. carnica, and A. m. ligustica), queen cell position within the grafted frame (Edge, Near Edge and Center), cell bar level (Upper and Middle) and batches on the acceptance rate of the grafted larvae, queen weights and queen cell length during April, May, July and August. The results indicated that the acceptance rate of the grafted larvae was significantly higher for ligustica as breeding (62.90%) or rearing (60.93%) colonies, for related (71.04%) than unrelated larvae (51.86%), for Center than Edge or Near edge positions, for the Middle bar than the Upper bar, for batch 1 than batch 2, and for July or August than April or May. The average weight of queens was significantly heavier for carnica (174.37 mg) than ligustica (167.58 mg) (as rearing colonies), for the Middle bar than the Upper bar, during April than May, July and August. The average length of queen cells was insignificantly longer for carnica (1.94 cm) than ligustica (1.90 cm) (as rearing colonies), and was significantly longer for April than May, July and August. | ||||
