Abstract
Leafhopper, Empoasca flavescens (Cicadellidae: Homoptera) and thrips, Scirtothrips dorsalis (Thripidae:Thysanoptera) are the major yield limiting biotic factors in castor. Growing resistant cultivars is an effective andeconomical approach to manage these insect pests. Thirty advanced breeding genotypes of castor were screened against the sucking pests along with susceptible and resistant checks during rabi 2018-19. The results exhibited that two genotypes (PCH-566 and JHB-1066) were found highly resistant and 13 genotypes (SHB-1027, SHB-1021, ANDCH1507, ICH-86, JHB-1061, ICH-538, ICH-515, BioMaruthi-999, JHB-1062, SHB-1033, SHB-1034, SHB1029 and ICH-404) were found resistant to leafhopper. Three genotypes (SHB-1034, ICH-404, JHB-1066) werefound promising against thrips.
