Abstract - This paper studies the biology of A. dorsata in the Melaleuca forest of Vietnam. The width of 158 A. dorsata combs was from 43-162 cm, and the height from 23-90 cm. About 3-4 weeks after nesting, a colony could store 4.1 2.6 kg of honey. The thickness of the worker brood comb was 3.3 cm and of the drone was 3.7 cm, but that of the honey comb was possibly 19.0 cm. The width of 10 continuous drone cells (58.1 1.4 cm, n = 90) is significantly larger than that of worker cells (55.7 1.7, n = 330). The depth of drone cells was 19.0 0.4 mm (n = 90) and of worker cells was 17.4 1.5 mm (n = 225). The weights of the newly emerged worker, drone and queen bees were 159.9 15.5 mg (n = 30), 168.5 10.4 mg (n = 30), and 272.0 40.1 mg (n = 9), respectively. Development time from egg to adult was 19.7 0.1 days (n = 30) for workers, 23.7 days for drones, and 16.5 days for queen bees. When a colony reached 121 cm 57 cm in size, it built 9.7 2.4 (n = 32 nests) natural queen cells. The volume of a queen cell was 1.300 0.159 mL (n = 28).
