ABSTRACT
The twenty genotypes of green gram namely Pant M4, ML 2410 , VGG 15-030, KM 2349, ML 818, Pusa 1671, Pusa 1672, Pant M6, PM 11-26, SML 1811, COGG 912, RMG 1092, PM 11-25, AKM 12-24, IGKM 06.26.5, RMG 1087, VGG 10-008, IGKM 05- 18-2, AKM 12-14, HUM-12 were raised under natural condition to study the population build-up of major sucking insect pests viz., Bemisia tabaci, Empoasca kerri, Caliothrips indicus on green gram. The results of present investigation revealed that maximum population of B. tabaci was recorded on the genotype ML 2410 (3.20 whitefly/split cage) followed by genotype PM 11- 25 (3.07 whitefly/split cage) and minimum in genotype RMG 1087 (1.38 whitefly/split cage) followed by genotype AKM 12-24 (1.67 whitefly/split cage). The maximum jassid population was recorded on genotype VGG 15-030 (3.41 jassid/ split cage) followed by genotype ML 2410 (2.92 jassid/ split cage) and minimum on genotype AKM 12-24 (1.63 jassid/split cage) followed by genotype AKM 12-14 (1.70 jassid/ split cage). The genotype PM 11-26 (2.06 thrips/5 flowers) showed maximum infestation of thrips followed by genotype Pusa 1671 (1.94 thrips/5 flowers) and minimum in genotype VGG 15-030 (0.21 thrips / 5 flowers) followed by genotype COGG 912 (0.45thrips / 5 flowers). The maximum yield was recorded in genotype VGG 10-008 (7.67 q/ ha), followed by genotype HUM 12 (7.33 q/ha) and minimum in COGG 912 (2.67 q/ha), followed by genotype VGG 15-030 (3.00 q/ha).

Key words : Genotypes, Green gram, Jassid, Screening, Thrips, Whitefly.
