    To discover the pollinator community of sunflower (Helianthus annuus L.) and different aspects of behavior, activity and pollination effect of Apis and non Apis bees, an experiment was performed at the research farm of Arid Agriculture University, Rawalpindi, Pakistan. The insect pollinator community was composed of eighteen species belonging to seven families and three insect orders. Apis mellifera and Xylocopa fenestrata were the most frequent visitors comprising 44% and 14% with maximum activity observed during early day hours.Visitation frequency of these two pollinators significantly varied at early and late observation times with no significant differences observed during the mid-day. The study also covered other aspects including visitation rate and duration of a single visit on flower heads. These also contributed significantly in increase of head diameter, total number of seeds per head, filled seeds, seed filling percentage and seed weight when compared with self-pollination.Presence of wild pollinators with commercial bee keepers can help in increase of crop yields and their good seed potential due to improvement of crossing of gene pool.
