The terai agroclimatic region of West Bengal has been surveyed in this study for the diversity of aphids and their predatory coccinellids during 2017-19. The collected specimens were studied in the laboratory of Department of Entomology, Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar. A total of 29 plant hosts were observed which revealed that Brevicoryne brassicae (L), Myzus persicae (Sulzer), Lipaphis erysimi (Kalt), Aphis gossypii (Glover) and Sitobion avenae (F) are the important species. Many coccinellids were observed predating on these, of which the dominant ones were Coccinella septempunctata (L), C. transversalis (F), Micraspis discolor (F), and Cheilomenes sexmaculata (F).
