Bimal da,
here is some evidence that some constituents of the nectar like nicotine like or caffeine like substances make the honey bee remember a plant for up to three days. there are scientific papers, but here s a news item i can get on the net to read in toto i thought you may like to know. *Another buzz for bees* *Blooms are more memorable when their nectar contains caffeine* *STEPHEN ORNES <https://www.sciencenewsforstudents.org/author/stephen-ornes>* MAR 24, 2013 — 1:00 PM EST https://www.sciencenewsforstudents.org/article/another-buzz-bees I have searched extensively to find if schefflera flower nectar contains caffeine or such chemical compound, but have not made any headway yet. but most plants that make such compounds put them first in the roots or leaves, so to save them from being eaten, because they are then bitter. some bitter nectar makes the bees fly off and search for another flower on the same tree, hoping to find sweet only nectar. that's the theory. Interesting conundrum. usha di On Sat, Jun 2, 2018 at 10:36 AM, J.M.
