Table 5 Impact of different modes of pollination on percent seed set, number of seeds per siliqua, and test weight (1000 seeds) in mustard

From: Larval feeding capacity and pollination efficiency of the aphidophagous syrphids, Eupeodes frequens (Matsmura) and Episyrphus balteatus (De Geer) (Diptera: Syrphidae) on the cabbage aphid (Brevicoryne brassicae L.) (Homoptera: Aphididae) on mustard crop
