Abstract:
An investigation was carried out for two consecutive kharif and rabi seasons (2017 and 2017-18) with a view to know the role of honey bees in sunflower, Helianthus annus L. Considering the importance of honey bees, Apis mellifera L. and Trigona sp. increased in production of seed yield with sugar and jaggery solutions (5%) like phagostimulants application during flowering season which attracted more number of bees. The data recorded higher bee visits on first (3.22 to 3.83 bees/5 capitula/2 minutes) and third day (3.34 to 3.78) after spray of both the sprays in kharif and rabi, 2017-18 in sunflower in the treatments of sugar and jaggery solution (5%). But, after three days of sprays, the influences of both the sprays declined.
