Variation the oviposition behavior by the stingless bee, Heterotrigona itama (Hymenoptera, Apidae, Meliponini)

Abstract A study to determine the variation of ovipositioning behavior of stingless bees, Heterotrigona itama (Cockerell, 1918) was conducted on three colonies on June 2015. A digital single-lens reflex (DSLR) camera with a macro lens attached was used to record every movement of H. itama in its colonies for 20 min hour between 0800 h and 2000 h for seven days and seven month. The daily egg laying rate and time for laying eggs in colony-B and colony-C were significantly (P ˂ 0.05) higher than the colony-A. However, time to close the brood was not significantly different among colonies. The fastest egg oviposition time was 4 s by the colony-B and the slowest was 6 s by the colony-A. In addition there are no significant trends on brood produced per day, laying time of eggs, and the closing time of the brood after the oviposition process from June to December 2016. This result is useful for understanding the behavior of egg laying process by the queen bees and necessary to deal with problems of management and reproduction in the near future.
