The use of bee attractants, Bee-Q, Bee Scent and Fruit Boost™ in the pollination of guava was evaluated. The bee visitation on guava flowers was made for a week, followed by estimation of quantitative and qualitative parameters in fruits. The different concentrations of bee attractants were evaluated to understand the honeybee visitation pattern of target crop for improving pollination efficiency. The observations indicate that the best mean foraging time on guava flowers was observed at 1000 hours (6.78) followed by 1200 hours (4.89) and 1400 hours st (3.78) . Bee scent @ 1.5 ml/l (15.67) was the most effective bee attractant in increasing bee visitation on the 1 day of spray in guava. Bee scent @ 2 ml/l (14.00) significantly attracted higher number of bee foragers than the control in guava plots. In addition, the plants sprayed with bee attractants significantly enhanced the length, diameter, and weight of fruits and total soluble sugars in guava. The present investigation suggests that the bee attractants increase marginal percentage of bee visitation and fruit parameters in guava.
