A preliminary study was conducted for nine days in a commercial crop field at Haripal in Hooghly district of West Bengal during the flowering phase of Brassica juncea L. to observe the periodical occurrence of various insect visitors and their role in pollination. 29 insect species belonging to 16 families under 7 orders were recorded as visitors of Brassica. As a whole, Lepidoptera had maximum number of species occurrence followed by Coleoptera and Hymenoptera. It has also been observed that species were found to visit in different parts of plant but most of them had a common location with flowers. It is indicated that most of the insect species has specific intension of nectar collection which led the pollination efficiency. Symbiotic interaction of the visited insect species was also studied.
