Abstract: A polymerase chain reaction based assay to distinguish six different ecotypes of the Spodoptera litura, a sporadic insect pest and a predominant defoliator of various crops was carried out. A total of 40 random primers were screened to reveal the existence of polymorphism between the populations. Among them eight showed scorable banding patterns and three primers(OPA-01 , OPA-05, OPM-01) exhibited distinguishable banding patterns. However, Chengalpattu and Chennai populations revealed their closed relatedness and Coimbatore population stood distantly from others.
