Abstract

Present investigation was undertaken to know the biochemical and molecular mechanism of rynaxypyr resistance
in Diamondback moth (P. xylostella.) Selection of DBM against rynaxypyr upto seven generations resulted in
development of about 34.88 folds resistance. Biochemical studies revealed increased Glutathione-s-transferase
and Carboxylesterase activity by 2.385 and 1.57 folds respectively, in resistant strain as compared to susceptible
strain. Native PAGE demonstrated the induced and over expression of the respective enzymes. In RAPD-PCR out
of 20 primers two primers gave maximum polymorphism and found to be potential markers for rynaxypyr
resistance in DBM.
