Abstract
The present studies were carried out to investigate the quantity (as % of accepted larvae, sealed queen cells and emerged queens) and quality (as weight of queen at emergence) of queen honeybees as affected by some internal environmental factors related to rearing process during late winter period and summer season of two successive years, (2018/2019) at Damietta governorate, (North Egypt). No significant difference was found for all parameters between the two studied years. Significant increase in the percentages of acceptance, sealed queen cells and emerged queens as well as weight of queens at emergence were obtained when introducing 32 than 48 larval queen cells into starter and finisher queen rearing colony, respectively. Larval queen cells which presented on the middle position, (174.6 mg./queen) of rearing bar produced more frequently queens with heavy weight than those presented on the peripheral ones, (169.9mg./queen). The artificially reared virgin queens during summer season were significantly heavier (175.7 mg. /queen) than those reared during the period of late winter, (166.9 mg./queen).
