Experimental trials were conducted at research field of Beekeeping Unit, Dholi (Muzaffarpur) during Rabi season of 2021-22 on coriander. Diversity among insect pollinators is very much essential for higher yield as well as maintaining ecological balance. Total visited insect pollinators were 76 belonging to 11 genus, 6 families and 5 orders. Apis mellifera was most abundant species at Dholi location (19.74 per cent). Several diversity indices revealed that the region has a substantial amount of rich diversity. Diversity of insect pollinators was due to richness of natural resources surrounding the research field. There were no predominant species present and number of individuals in maximum species was quite similar. Evenness in population was due to the presence of flowering in crops at surrounding fields.

Coriandrum sativum L, Insect pollinators, Diversity index, Richness, Evenness and Dominance

In the present study, coriander flowers were visited by different insect pollinators. Total visited insect pollinators were 70 at Dholi belonging to 11 genus, 6 families and 5 orders. Pollinators from Apidae family contributed more pollination with more than 50 per cent share in population abundance. Various diversity indices showed that area had sufficiently rich diversity. Population of each species was more or less similar and no any over dominated species observed. Abundance of insect pollinators at Dholi location was due to richness of natural resources surrounding the research field. Slight variations between previous reports and results of the present study are may be due to change in the crop variety, floral reward, existing foraging source, climatic condition and native pollinator’s guilds. This study furthermore provides an insight into the efficient species, foraging habits and surrounding flora that might encourage more pollinators to this cross-pollinated crop.
