- Abstract
Resistance potential of 210 groundnut accessions against leaf caterpillar, Spodoptera litura Fab. was evaluated during Rabi, 2018-2019 and Kharif, 2019 seasons at Thandavankulam village, Nagapattinam district of Tamil Nadu, India. Weekly observations on larval population and percent damage revealed a higher level of leaf caterpillar incidence and infestation during Rabi, 2018 than Kharif, 2019. Based on the standard scale, none of the accession was found immune during both the seasons. During Rabi season, 31 accessions were rated resistant while 40 accessions were moderately resistant. During Kharif season, 121 accessions were rated resistant because of lesser population of S. litura.
