Abstract: The efficacy of larval grafted queen was determined in comparison to queen reared naturally in <em>Apis mellifera</em> L. colonies. The results showed that larval grafted queens were significantly superior (p&gt;0.05) over naturally produced queen. The maximum brood area (9525.50 cm²), pollen area (358.40 cm²), honey store (2.70 kg), cleanliness (3.55 g), queen weight (189.80 mg) and egg laying (1835.00 eggs per day) were recorded in larval grafting method (T1) and also showed highly significant difference over natural reared queen. The minimum brood area (6445.30 cm²), pollen area (210.20 cm²), honey store (1.85 kg), cleanliness (1.00 g) and egg laying (1250.00 per day) was recorded in emergency impulse reared queen (T4) Significant (p&gt;0.05) differences were observed among all the treatments.
