abstract
Studies on diversity on insect pollinators sweet basil was carried out at Instructional Farm, Rajasthan College of Agriculture, MPUAT, Udaipur. In the present study, the insect pollinator diversity was recorded during the flowering period from 21/08/2017 to 29/10/2017 on sweet basil. The major insect pollinators belonged to 5 different orders: Hymenoptera, Lepidoptera, Coleoptera, Diptera and Hemiptera that were observed during different hours of the day. The maximum Shannon Weaver diversity index (1.20) for transect sampling was observed during 16:00 to 18:00 hours; while minimum (0.94) was during 10:00 to 12:00 hours. The Shannon Weaver diversity index for insect pollinators trapped in the colored bee bowls (Yellow, White & Blue), white bee bowl was recorded maximum (1.59) and minimum in yellow bee bowl (1.51); whereas, in yellow pan trap (1.34) was observed.
