Peak activity of A. dorsata, A. meilifera, A. cerana, A. florea (2.62, 2-33, 1.82 and 1.95, bees/10 flowers/min, respectively) and other pollinators (1.01 pollinators/10 flowers/min) was observed at 1200 h. Fruit boost spray at both the concentrations attracted significantly more number of A. dorsata, A. meilifera and A. florea upto fifth day after spray during first and second spray and upto third day during third spray. Bee-Q spray was the second best in attracting significantly higher number of bees upto third day during first and second spray and upto one day during third spray. Sugar solution and tuberose scented water were able to entice significantly higher number of bees only on first day after spray.ennullThesis
