Observations were made on 45 to 20400 flowers per treatment. The flowers were subjected to different treatments: Free flowers (Treatment 1), bagged flowers (treatment 2), castrated and free flowers (treatment 3), and castrated and bagged flowers (treatment 4). Some (8695 and 3325) flowers of <em>Glycine max</em> (Fabaceae) were observed in 2016 and 2017, respectively, for the diversity and Frequency of insect visits. For results, 1527 visits of 13 insect species distributed in seven orders were recorded on <em>G. max </em>flowers. The most dominating Hymenoptera observed was <em>Apis mellifera,</em> with 40.20 % of the total insect visits. The highest number of insect pollinators harvested in the flowers of this Fabaceae was between 8h-9h. The studied insects have a positive impact on the yields of this plant. This positive impact of the pollinator insects on the yields was 26.29 %, 16.13 %, 15.02 and 4.45 % in fructification rate, number of seeds pod, the weight of seeds, and percentage of normal seeds respectively. The avoidance of pesticide treatment of plants during flowering could be a good management strategy to improve on plant yield.</p>}, journal={JOURNAL OF ADVANCES IN AGRICULTURE}, author={Dounia and Clautin Ningatoloum and Chantal Doukaa and Elono Azang Pierre Stephan and Amada Brahim and Joseph Lebel Tamesse and Fernand-Nestor Tchuenguem Fohouo}, year={2020}, month={Jun.}, pages={99–107} }
