Population dynamics studies of mustard aphid, L. erysimi on three Rapeseed-mustard varieties i.e. RH 0749, HNS 0901 and BSH 1 belonging to three Brassica spp. i.e. B. juncea, B. napus and B. rapa revealed that mustard aphid was available in the field from 3rd Standard metrological week (SMW) (January) to 11th SMW (March). The peak aphid population (23.33-86.05 aphids/10 cm main apical shoot) was recorded during 9th SMW in all Brassica species (both timely and late sown) except in BSH 1 (timely sown) in which it attained peak (31.98 aphids/10 cm main apical shoot) in 6th SMW. The mustard aphid population had negative correlation with evening relative humidity under timely sown conditions and positive correlation with maximum temperature under late sown conditions in B. juncea (RH 0749) and B. napus (HNS 0901). While in B. rapa (BSH 1), the population of mustard aphid did not have any correlation with any of the weather parameters.
