Description Mustard, Brassica juncea (Gunther) is an oftenly cross pollinated oilseed crop of India. Rapeseed and mustard are, grown on an area of 6.23 million hectares with an annual production of 5.88 million tonnes. The average productivity of 944 kg/ha, is very low as compared to the world average of 1262 kg/ha. (Anonymous, 1995). About 40 insect species are associated with this crop but among them mustard aphid Upaphis erysimi (Kalt.) is considered as key pest on this crop. The saw fly Athalia lugens proxima (Klug); painted bug, Bagrada hilaris (Burm.); pea leaf miner, Chromafomyia horticola (Goureau) and Bihar hairy caterpillar Diacrisia obliqua (Walker) no doubt are of major economic importance but are sporadic in nature (Bakhetia and Singh, 1992). Honey bees accomplish major cross pollinating role among other agents (Kapil et al. 1971). Flowers of mustard are extremely attractive to foraging honey bees and are considered an important source of honey by the bee keepers. Since, the use of insecticides to control pests is one of the choicest method nowadays but their indiscriminate use has led to the poisoning of many beneficial organisms as well as food commodities. Commonly used' insecticides to manage the mustard pests complex are oxy-demeton methyl, dimethoate, endosulfan and cypermethrin (Bakhetia, 1986), but at the same time honey bees are poisoned in the field resulted in heavy mortalilty of the bees.
