Abstract

Mustard aphid Lipaphis erysimi (Kaltenbach) appeared as a major pest in Jobner and its incidence is highly influenced by weather parameters and natural enemies. Therefore, a study was conducted to understand their population dynamics. The commencement of the aphid incidence was recorded in the fourth week of December (52th SMW) which gained a peak in the 6th SMW i.e., second week of February and declined thereafter and reached its lowest during 9th SMW i.e., first week of March. Among the natural predators Coccinella septempunctata (L) and Xanthograma scutellarae (F) were found predating on L. erysimi and showed significant positive relationship (r= 0.997* and r = 0.883*). The population of X. scutellarae showed a significant negative correlation (r=-0.658*) with minimum temperature.
