Queen honeybees of Apis mellifera ligustica and Apis mellifera syriaca were raised to investigate physiological and reproductive characteristics and to determine the most suitable time for queen rearing under semi‐arid conditions in Jordan. The queen rearing season as well as the origin of the queens affected the queens’ weight, acceptance, preoviposition period, volume of the spermatheca, and quantity and quality of sperm in the spermatheca. Italian bees were heavier than Syrian bees at emergence. The introduced queen acceptance rate appeared to be a genetic influence of the queen: A. m. ligustica virgin queens were accepted at a higher rate than were A. m. syriaca queens. There were large seasonal variations in the acceptance rate. Experimental bee colonies accepted their virgin queens during spring with good honey flows at a higher rate compared to the other rearing periods. The greatest mating success was achieved in May and the smallest was during July and August. The preoviposition period was shorter in the Syrian than in the Italian queens, and was longer during summer for both honeybee subspecies. The volume of the spermatheca was smaller in Syrian bees and the spermatheca had lower numbers of spermatozoa compared with Italian bees. Thus, under semi‐arid Mediterranean region conditions, it is highly recommended to raise virgin queens in the spring months only to obtain their highest quality.
