The present study titled “Selection of different Okra genotypes against Earias spp.” was carried out at Entomological Research Institute, Faisalabad and GC University Faisalabad. Twenty genotypes of okra viz., Parbhani kranti, Pusa swani, Ikra-1, Clean spineless, Pussa green, Ikra-2, Sanam, Dera local, Pusa green, Makhamali, Okra-3, Ikra-3, Green wonder, Kirn-51, PMS-55, Punjab selection, Arka anamika, Namdahari. Diksha and Anarkali with the objective to find their comparative resistance susceptibility were studied during 2011 regarding fruit infestation percentage caused by Earias spp. From these preliminary study, nine genotypes of okra showing three susceptible (Parbhani kranti, Pusa swani and Ikra-1), three intermediate (Makhamali, Okra-3 and Ikra-3) and three comparatively resistant (Anarkali, Diksha and Namdahari) were selected for final study during 2012. The genotype Parbhani kranti showed susceptible trend with fruit infestation of 17.83 percent during preliminary screening trial during 2011 and fruit infestation of 4.78 percent during final screening trial during 2012 while the genotype Anarkali was found to be comparatively resistant resulted in minimum fruit infestation i.e., 7.60 during preliminary screening trial and 1.30 percent during final screening trial. The maximum Host Plant Susceptibility Indices (HPSIs) were recorded to be 16, 19 ad 17 percent for Parbhani kranti during 2011, 2012 and on cumulative basis of 2011 and 2012, respectively and this genotype was found to be comparatively susceptible, whereas minimum HPSIs were observed to be 7.0, 5.0 and 4.0 percent on the genotype Anarkali during 2011, 2012 and cumulative basis of both years, respectively and was found to be comparatively resistant genotype.
