Abstract
Field study was conducted during the 2023-24 at the Agricultural College, ANGRAU, Bapatla, to investigate the diversity and Rabi abundance of insect pollinators in sesame (L.).Thirty insect species belonging to four orders were recorded visiting Sesamum indicum sesame flowers.Among these, (Indian honey bee) was the most dominant pollinator.The family Megachilidae was Apis cerana indica dominating among the pollinator guild.Pollinator activity varied throughout the day, gradually increasing from 09:00 h and peaking between 09:30 and 11:05 h, before declining after 14:00 h.However, species,,, Megachile laticeps Megachile lanata Megachile cephalotes Ceratina binghami Ceratina, and sp.exhibited peak activity between 12:30 and 14:05 h.The Shannon-Wiener index (H) was lowest during the early morning hours but increased throughout the day, showing two peaks corresponding to morning and noon activity.Both the Berger-Parker dominance index (d) and Shannon's diversity index showed a positive correlation with floral abundance.These findings highlight the diversity, diurnal activity, and ecological significance of pollinators in sesame, emphasizing the need for their conservation and sustainable management.
