Diversity of insect pollinators visiting the tree, Relative abundance of the pollinators, Foraging behavior in term of Foraging rate, Foraging duration and loose pollen grains adhered to the body. On the basis of the data, performance score and pollinating index (PI) of each Polistes herbreaus and Rhynchium flavolineatum was the most efficient pollinator of Ber (Ziziphus maurtiana). No other species viz Apis cerana Apis dorsata Apis mellifera are found on the Ber.
