Aphid-induced phytochemicals in Brassica juncea (L.) Czern & Coss. afflicting host preference and bionomics of Lipaphis erysimi (Kaltenbach)

Bionomics of an insect and metabolic flux of the host plant are important tools to decipher the status of plant resistance against insect species. This study illuminates vital information on aphid-induced levels of phytochemicals in the siliquae of Brassica juncea cultivars and their effect on host selection and population growth parameters of Lipaphis erysimi. The current study unveiled that the siliquae preference, intrinsic rate of increase (r), finite rate of increase (λ), gross reproductive rate (GRR) and net reproductive rate (R0) were significantly lower on Pusa Mustard 27, DRMR 150-35, RLC 3, NRCHB 101, Pusa Mustard 26 and Pusa Mustard 25. However, mean generation time (T) and doubling time (DT) of L. erysimi were significantly longer (P<0.001) in these genotypes. These cultivars were also found with elevated levels of aphid-induced phytochemicals and their associated enzymes, except in a few cases.
