Abstract :
The present studies were conducted during 2008-2010, to test the susceptibility of onion crop to a globally recognized pest of onion Thrips tabaci Lindeman. The results revealed that genotype VRIO-3 was highly susceptible one having 181.7 thrips per plant. The genotype Desi Large was moderately resistant having 94.2 thrips per plant. Survey of susceptibility of onion cultivars revealed that there is a scarcity of thrips resistant varieties in agro-ecosystem of Punjab, Pakistan. So, thrips resistant varieties must be developed to combat the menace to thrips attack. This study provides a guideline to the genetic engineers and conventional breeders.
