Abstract

The field experiment on the population trend of Lipaphis erysimi (Kalt.) was conducted at New Developmental Farm, The University of Agriculture, Peshawar, from 2021 to 2022. The results revealed that aphids appeared at rates of 1.00 and 0.75 per leaf during January 8-14, reaching their peak at 10.10 and 11.35 per leaf during March 12-18. Subsequently, they disappeared from the field after April 9-15 in both years (2021 and 2022). Therefore, as L. erysimi reaches its peak population during SMW 11 (March 12-18), plants should be closely observed during this period, and control methods with rapid curative action should be applied if needed.
