Study on seasonal incidence of insect pests on rapeseed-mustard was conducted on the Oilseed Farm Kalyanpur, Kanpur during rabi,2018-19. The occurrence of three major insects were recorded viz., Mustard sawfly Athalialugens proxima Klug which was observed at seedling stage, whereas painted bug Bagrada cruciferarum Kirkaldy was observed at two different crop stages: firstly at seedling stage and secondly at maturity stage and mustard aphid Lipaphiserysimi Kaltenbach appeared from flowering to pod bearing stage of mustard crop. The cloudy weather condition and temperature from 8-32°C favoured the insect pests multiplication. Out of the six Brassica species, viz Urvashi, GSC-6, BSH-1, T-27, YST-151 and DRMR IJ-31; T-27 was least attacked by the mustard aphid.
