Abstract: The present study was made to evaluate field bean genotypes for tolerant against field bean spotted pod borer. The experiment was conducted during 2017-18, at college of agriculture, IGKV, Raipur, Chhattisgarh. By growing a total of 118 genotype accessions on July, 2017 in an augmented design. The study revealed that the major insect pest spotted pod borer was attacking in field bean genotypes. The incidence of a spotted pod borer started from last week of October. Further incidence was increased and recorded the peak activity of spotted pod borer larvae per plant were observed during second week of December with the population of 2.96 larvae/plant. The result of screening the field bean genotypes against spotted pod borer showed that among the 118 genotypes, 14 genotypes were least preferred by insect pest and considered as tolerant. However, 102 and 2 genotypes were moderately and highly susceptible.
