An experiment was conducted using five different wheat genotypes to determine their resistance to Sitotroga cerealella (L.) at Chaudhary Charan Singh Haryana Agricultural University, Hisar during the year 2018-2020. The experiment was carried out in Completely Randomized Design (CRD) with three replications in a control temperature of 29±2?C with 65±5% relative humidity. The cultures were maintained in glass jars of 1 kg capacity containing the wheat grains and 25 adults of S. cerealella were released in these jars, separately. The results were evaluated by calculation of susceptibility index, percent grains damaged and percent weight loss of wheat grains against the infestation of S. cerealella. Among all the genotypes percent grains damaged (52.91%), percent weight loss (21.75%) and was found to be ‘highly susceptible’ genotype, while the lowest percent damaged grains (25.25%) and weight loss (8.64%) were recorded in genotype HPBW 1 and was found the ‘susceptible’ genotype against the infestation of pest, while all the remaining genotypes were intermediary to the pest attack.
