An experiment was conducted using Randomized Complete Block (RCB) design to find the effects of initial colony strength of Apis mellifera L. on honey production with four levels of initial populations: 4 frames (9,800), 6 frames (14,700), 8 frames (19,600) and 10 frames (24,500) of adult honeybees per colony replicating 5 times during litchi flowering season (February to April, 2003) in Chitwan. This study revealed the exponential increase in honey production {Y = 4.22 – 0.7325 X + 0.09625 X2 (4 ≤X ≤ 10 comb covered by bees per colony) and Y = 4.22 – 0.000299 X + 0.000000016 X2 (9,800 ≤ X ≤ 24,500 honeybees per colony), n = 4} producing 2.32, 1.59 and 1.18 times more honey from initially 10-, 8- and 6-frame colonies as compared to the honey production of 2.82 kg/colony from 4-frame colonies. There was significantly positive linear correlation among colony attributes like colony strength, brood rearing, comb building, foraging activity and honey production.
