The influence of sorghum varieties on the biology of sorghum shoot bug Peregrinus maidis (Ashmead) when evaluated it was observed that the highly resistant variety (Y-75) led to reduced incubation, nymphal and total lifecycle periods (4.30± 1.04, 8.60± 0.76 and 33.50± 3.01 days, respectively). Fecundity was reduced to minimum in variety Y-75 (21.00± 3.60), in maximum while it was Hathi Kunta (55.30± 7.01), while in M 35-1 it was intermediate (42.00± 8.74). The survival was the least on Y-75 (25%) followed by that on M 35-1 (60%) and maximum was on Hathi Kunta (90%). The total lifecycle (days) was significantly less on Y-75 (33.50± 3.01 days) and maximum on Hathi Kunta (45.00± 4.83).
