Abstract:

The diversity of insect visitors on mustard (Brassica juncea L.) was studied at Dr. Y. S. Parmar University of Horticulture and Forestry Nauni, Solan. A total of 88 insects belonging to 63 genera under 31 families and 9 orders were found to visit the mustard bloom. Order Hymenoptera formed higher percentage of the insect visitors in scan sampling. Apis cerana and A. mellifera abundance were higher by scan sampling methods. Relative abundance (by scan sampling) and diversity (by sweep net method), in general, was statistically more at full bloom than at onset and end of bloom. Other dipterans were the dominant insect trapped in mustard crop by fluorescent pan trap. All the three methods namely fluorescent pan traps, scan sampling and sweep net method are essential for determining pollinator diversity as no single method is fully reliable. Highest seed set, seed siliqua-1 and 1000 seed weight was obtained by open pollination followed by hand pollination. The minimum seed set, seed siliqua-1 and 1000 seed weight was observed in case of pollinators exclusion.
