Abstract
Many essential plants, including high-quality food and industrial oils, common vegetables, and weeds, belong to the Brassicaceae family, which includes the genus Brassica. The strong attack of many pests and diseases not only degrades the quality of crops, but also significantly affects the oil content of many oil-producing brassica crops. Aphids, a severe insect pest of Brassicaceae species, which include key vegetable and oilseed crops, have evolved with their host plant to become the most economically important insect pest of agricultural Brassicas. This page provides an overview of pest biology in general insect habit and nature of damage, scenario in case of Nepal and Asian countries and the management strategies for their population control which includes physical, cultural, biological, innovative methods, plantation of resistant varieties, chemical applications and integrated pest management technologies. Some cultural techniques to deal with the aphid population include fertilizer applications at the proper dose, irrigation, and resistant cultivars. For crop security, natural enemies are currently effective and spectacular.
