This present study was conducted for the evaluation of different onion cultivars against onion
thrips Thrips tabaci L. (Thysonoptera: Thripidae). The data regarding maximum population of adults on
Marvi with 3.4 adults per leaf and minimum number of adults on Red Orb with 1.6 adults per leaf were
recorded. According to Physico-morphic characters the height and girth of Marvi cultivar was minimum
with 14.95 cm and 9.02 mm respectively. Maximum height of Red Orb cultivar with 19.94 cm and girth
with 9.84 mm were noticed. The leaf infestation of Marvi was maximum with 43.04 percent while
minimum infestation was recorded on Red Orb i.e. 22.58 percent. Maximum yield was observed on Red
Orb with 151.4 g per 5 plants while the Marvi cultivar had low yield 100.3 g per 5 plants.
