Screening of groundnut (Arachis hypogaea L.) genotypes against Helicoverpa armigera H, Spodoptera litura, and Aproaerema modicella was conducted during Kharif 2019-20 at Oilseed Research Station, Latur. Among 50 germplasms screened for Helicoverpa armigera, Spodoptera litura and Aproaerema modicella larvae incidence, one entry was found ‘Highly Resistant’ against Helicoverpa armigera larvae i.e. ISK-I-2019-17 and ten germplasm lines were categorized as ‘Resistant’ germplasms. Sixteen germplasm lines were found as ‘Moderately Resistant’ and thirteen as ‘Susceptible’ while ten varieties was found ‘Highly susceptible’ to Helicoverpa armigera larvae. Whereas, Out of 50 germplasms none of the entry was found ‘Highly Resistant’ against Spodoptera litura and eleven germplasm lines were categorized as ‘Resistant’ germplasms. Fifteen germplasm lines were found as ‘Moderately Resistant’ and twelve as ‘Susceptible’ while twelve germplasm lines were found ‘Highly susceptible’ to Spodoptera litura. Two of the entries were found ‘Highly Resistant’ against Aproaerema modicella larvae and twelve germplasm lines were categorized as ‘Resistant’ germplasms. Fourteen germplasm lines were found as ‘Moderately Resistant’ and twelve as ‘Susceptible’ while ten germplasms were found ‘Highly susceptible to Aproaerema modicella larvae. The check JL-24 was found ‘Susceptible’ to Helicoverpa armigera, Spodoptera litura and Aproaerema modicella larvae. Among 50 germplasm lines screened for respective lepidopteran pest of groundnut, most of the germplasm lines were found moderately resistant to Helicoverpa armigera, Spodoptera litura and Aproaerema modicella larvae.
