The present study evaluated its biological and morphological parameters on different wheat varieties. The results revealed that its incubation period was varied from 7.01-8.91 days, being longest on the variety Faisalabad-08, and shortest on Sehar-06. Its total developmental period from egg-adult varied from 48.44- 64.16 days, respectively; male and female longevity was 19.14, and 17.02 days on Sehar-06. The weight of 6<sup>th</sup> instar larvae ranged from 6.21 to 7.11 mg, while the survival was maximum and minimum on Sehar-06 and Faisalabad-08, respectively. The minimum and maximum weight losses were observed in Faisalabad-08 and Sehar-06, respectively. Thus, Sehar-06 was observed to be the most susceptible variety giving maximum fertility and fecundity.</p> ER -
