Abstract
An investigation about the power of redwood bark sap to invite stingless bee arrival had been done at Biology campus area, The University of Sriwijaya, Indralaya, South Sumatera, Indonesia; during Nopember 2010. Redwood breadfruit bark have been hurt for outcoming the red sap, and duration time for stingless bee arrival be measured then. Meanly, in 17 minutes, stingless bee had came for red sap; and in 5 minutes for breadfruit. Chemical test of redwood sap after soluted in methanol and put on gelsilicon chromatography with ethil-acetate and methanol (1:1), and sprayed by sulphic acid indicate that the compounds is terpenid (tannin) for red wood sap, and tannin and alcaloid for bread fruit sap.
Highlights
At an afternoon, one year ago, a neighbor cut the red wood trunks in front of the house
What were the chemical compounds in the red sap? And what for stingless bee to keep it? The study on Trigona and Pterocarpus begin at that day
At least there are 100.000 chemical compounds produced by 200.000 species of flowering plants in their growth and development
Summary
One year ago, a neighbor cut the red wood trunks in front of the house. Many red elastic sap/gum came out from the bark and lot of insects, stingless bee, hold the gum and keep it i n their leg baskets. Most of chemical compounds of plant identified, were functioned as volatile attractant for insects. Broad chambers containing queen cells are removed al ong with same adult bees, and placed 1-2 metres away from the original colony. The nest of stingless bees usually consist of an external tube, internal tunnel, resin dumps, wax dumps, foot pots for storing pollen and honey, brood and nest envelopes like involucrum and batumen. Stingless bees need flower nectar and pollen for their food.
