The present study deals with the foraging activities and pollination efficiency of Tetragonula iridipennis in cucumber (Cucumis sativus) under protected conditions. Experiments were conducted during two seasons (summer and winter) with three different treatments: open pollination (OP), pollinator exclusion (PE) and stingless bee pollination (SBP) in Assam, North East India. The foraging activity of T. iridipennis was checked in SBP treatment at different timings after installing a 15,504 cm3 beehive. The pollination efficiency of T. iridipennis was also examined among the three selected treatments. The peak period of visitation on cucumber flowers was recor­ded during 0800-0900 h of the day during both seasons. The yield increase of SBP over PE during both seasons was five times higher. These findings indicate the significance of T. iridipennis as an effective pollinator in greenhouse cucumbers

Experiments were conducted during two seasons (summer and winter) with three different treatments: open pollination (OP), pollinator exclusion (PE) and stingless bee pollination (SBP) in Assam, North East India. The foraging activity of T. iridipennis was checked in SBP treatment at different timings after installing a 15,504 cm3 beehive. The pollination efficiency of T. iridipennis was also examined among the three selected treatments. The peak period of visitation on cucumber flowers was recor­ded during 0800-0900 h of the day during both seasons. The yield increase of SBP over PE during both seasons was five times higher. These findings indicate the significance of T. iridipennis as an effective pollinator in greenhouse cucumbers
