Screening of different okra genotypes against fruit borer (Earias spp.) (Lepidoptera: Noctuidae) on Okra Crop

The present study was carried out at experimental area of vegetable research institute,(aari) faisalabad to test the resistant/susceptibility responses of 25 genotypes of okra against fruit borer under field condition during 2013. from the preliminary screening trial,nine genotypes of okra including three comparatively resistant (sabz pari,green wonder and super star),three genotypes with intermediate response (lakshami-24,cok-1418 and ikra anamika) and three comparatively susceptible genotypes (pusa sawani,ikra-2 and okra-3) were selected for final screening trial during 2014. during preliminary and final screening trials genotype pusa sawani proved susceptible genotype,while sabz pari was found comparatively resistant genotype. maximum host plant susceptibility indices (hpsi) was observed in pusa sawani i.e. 16% and was found susceptible,while minimum hpsi i.e.,6% was recorded in sabz pari and found to be comparatively resistant genotype. copyright 2015 zoological society of pakistan.
