Abstract: Aphids are among the most destructive pests of cruciferous crops, and recent observations have highlighted a heavy incidence of Lipaphis pseudobrassicae (Davis) on knol-khol (Brassica oleracea var. gongylodes) at the Horticulture Farm, College of Horticulture, Anand Agricultural University (AAU), Anand. This aphid species, comprising both nymphs and adults, infests the crop by lacerating leaf tissues and sucking sap, leading to visible symptoms such as leaf curling, yellowing, stunted growth and a general decline in plant vigour. The damage caused significantly reduces the marketable yield and aesthetic quality of knol-khol, making it a matter of economic concern. In addition to its impact on knol-khol, L. pseudobrassicae is known for its polyphagous nature and wide host range, which includes various other economically important crops. This amplifies the pest’s threat level and raises concerns over its potential to spread across different agro-ecosystems. The possibility of overlapping host crops grown in the vicinity increases the chances of cross-infestation and makes the management of this pest more challenging. Therefore, to mitigate the risk posed by L. pseudobrassicae, it is imperative to carry out systematic monitoring and research focused on its geographic distribution, host preference, seasonal incidence and damage potential. Understanding these aspects will facilitate the development of integrated pest management (IPM) strategies, including cultural, biological and chemical control methods. This will not only help safeguard knol-khol crops but also prevent potential outbreaks in other susceptible crops, thereby ensuring sustainable agricultural productivity
