The investigations were carried out on succession of sucking pest complex infesting greengram during  Kharif2010 at Junagadh Agricultural University, Junagadh. During the study, jassid, Empoasca kerri Pruthi,  whitefly, Bemisia tabaci (Gennadius) and thrips, MegalurothrOs distalis (Karny) were the major sucking  insect pests infesting the crop. Population dynamics of jassid, E. kerri revealed that the pest appeared during  2nd week after sowing and its population multiplied steadily in succeeding weeks and reached at a peak (5.20 nymphs/3 leaves) during 9th week after sowing. The whitefly, B. tabaci initiated its infestation from rd week after sowing with a population of 0.60 whitefly/3 leaves and peak with 5.40 whitefly/3 leaves at 9th week after sowing. Similarly, Thrips, M. distalis infestation was started from 2nd week after sowing with the population of 0.40 thrips/3 leaves and increased gradually to attain a peak (4.20 thrips/3 leaves) during 10th
week after sowing.
