The experiment was conducted at experimental field of Entomology Section, Agriculture Research Institute, Tandojam during the season 2017-18. Using eight mustard varieties such as S-9, Sindh Raya, P-21, Early Raya, Bard-2, P-4, P-78 and Toria Selection to compare the resistance of varieties against sucking insect pests, and To compare the yield of Mustard varieties. The monitoring of sucking insect pests was started on 18th December 2017 and lasted on 05th March 2018. Weekly record of the insect pests (whitefly, thrips, jassid and aphid) infestation on mustard crop varieties was maintained. The population of whitefly (Bemisia tabaci Genn.), thrips (Thrips tabaci Lind.), jassid (Amrasca devastans Dist.) and aphid (Lipaphis erysimi Kalt.) varied significantly among varieties (P<0.05), observation dates (P<0.01) as well as varieties × observation dates interaction (P<0.01).The lowest whitefly population of 2.88±0.37/plant was monitored on mustard variety ‘S-9’; while highest population of 4.36±0.42/plant was recorded on variety ‘Bard-2’. Thrips showed that lowest thrips population of 7.30±1.81/plant was recorded on mustard variety ‘S-9’; while the highest population of 10.63±2.84/plant was recorded on variety ‘Bard-2’. Jassid population was lowest (12.03±2.93/plant) on mustard variety S-9; while the highest population of 14.95±3.39/plant was monitored on variety ‘Bard-2’. Aphid was lowest (3.59±0.99/plant) on mustard variety S-9; while the highest population of 5.10±1.23/plant was monitored on variety ‘Bard-2’. The crop yield was recorded as 2.36, 2.38, 2.41, 2.35, 2.21, 2.37, 2.22 and 2.4 kg/plot in variety S-9, Sindh Raya, P-21, Early Raya, Bard-2, P-4, P-78 and Toria selection, respectively.
