Abstract

During the field survey, eight insect visitors visiting rapeseed mustard (Brassica rapa var. toria) were recorded, belonging to three major insect orders: Hymenoptera, Lepidoptera, and Diptera. Hymenoptera was the dominant order, comprising Apis cerana himalaya, A. dorsata, A. florea and Sceliphron caementarium. Lepidoptera included Pieris canidia and Pontia daplidice, while Diptera consisted of Sphaerophoria scripta and Helophilus pendulus. Among all visitors, Apis cerana himalaya was the most abundant species, accounting for 58.7% of total insect visitors, followed by Sphaerophoria scripta (9.65%), Helophilus pendulus (8.61%), Apis florea (7.62%), Pieris canidia (5.83%), Pontia daplidice (5.14%), and Apis dorsata (4.21%). Sceliphron caementarium showed the lowest abundance (0.95%). The predominance of Hymenopteran species, particularly A. cerana, highlights their important role in mustard pollination and seed set, while hoverflies and butterflies also contributed to effective cross-pollination.
