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.
