Abstract: 

Out of fifteen genotypes of cluster bean, Cyamopsis tetragonoloba (Linn.) Taub. screened against leaf hopper, Empoasca motti Pruth; whitefly Bemisia tabaci (Genn.), and aphid, Aphis craccivora Koch; none was found immune. Based on statistical categorization; the genotypes, RGC–197, RGC–1031, RGC–986, RGC–1017, RGC–1055 and RGC– 1076 were found least susceptible to leaf hopper, genotypes RGC–1077, RGC–1066 and RGC–1078 moderately susceptible and genotypes RGC–1038, RGC–1003, RGC–1002, HGS–365, RGC–936 and HGS–563 were highly susceptible. The genotypes, RGC–1017, HGS–365, RGC–986, RGC–197, RGC–1031 and RGC–1076 were least susceptible, genotypes RGC–1077 and RGC–1066 were moderately susceptible and RGC–1038, RGC–1003, RGC–1002, RGC–1078, RGC– 936 and HGS–563 were highly susceptible to whitefly. The genotypes, RGC–197, RGC–1017, RGC–1031, RGC–986 and RGC–1055 were found least susceptible; RGC–1077, RGC–1076, RGC–1038, RGC–1078, RGC–1066 and RGC– 1002 as moderately susceptible; and RGC–1003, RGC–936, HGS–365 and HGS–563 as highly susceptible to aphid.
