CHARACTERIZATION OF NEST STRUCTURE AND FORAGING ACTIVITY OF STINGLESS BEE, GENIOTRIGONA THORACICA (HYMENOPETRA: APIDAE; MELIPONINI)

Meliponiculture is the activity of stingless bee keeping, where the colony of stingless bees extracted from wild for the purpose of domestication. The study of stingless bee nest architecture of selected species brings benefit to this newly booming industry. Geniotrigona thoracica, is one of the largest stingless bee in Malaysia and has potential used in meliponiculture. The objectives of this study are to determine nest structure and growth, foraging activity and morphometry of worker bee. Colonies (n=3) of G. thoracica were used to study the nest structure and growth, foraging activity and morphometry of worker bee. Sampling was done for a period of one year from July 2013 until June 2014 for nest growth and foraging frequency. For morphometry study, worker bees were sampled from each nest Result showed external nest structure formed in brown mount shape and the internal nest formed by three components, horizontal brood combs that surround with honey pots and pollen pots. The nest dynamics of G. thoracica changes according to the season. The peak time foraging frequency of G. thoracica was in between 1000 hrs until 1200 hrs.  From morphometry study of worker bee, result for flight cost and aggressive cost were 8.48 ± 0.440 and 0.06 ± 0.004 respectively.
