Abstract

Pollinators provide key services to both natural and agricultural ecosystems. Agricultural productivity depends, in part on pollinator populations from adjacent semi natural habitats.The diversity and abundance of different insect visitors on sunflower (Helianthus annuus L.) were studied at Pantnagar. A total of 12 insect visitors belonging to order Hymenoptera (9), Diptera (1), Lepidoptera (1), and Coleoptera (1) were observed visiting the blossom of sunflower. The abundance (percentage of insect/m2/2min.) of Hymenopterans were maximum (86.09%) followed by the Dipterans (22.80 %) and others (3.87%). In Hymenopterans, the honeybees (Apis bees) were observed maximum (65.22 %) followed by non Apis bees (20.39 %) and the scolid wasp (1.69 %).
