Field evaluation of twenty early maturing pigeonpea genotypes against legume pod borer, Maruca vitrata (Geyer) revealed that the incidence of Maruca population was significantly higher in ICPL 98016 (1.38 webs and 2.09 larvae plant−1 at 15 days after flowering (DAF), 1.48 webs and 1.92 larvae plant1 at 30 DAF) and lower in ICPL 98013 (1.11 webs and 1.54 larvae plant−1 at 15 DAF, 1.18 webs and 1.47 larvae plant−1 at 30 DAF). The percent pod and locule damage was significantly lower in ICPL 98009 (17.16 and 12.52%). ICPL 98016 showed maximum damage rating (7.0 at 15 DAF and 7.6 at 30 DAF), whereas ICPL 98013 recorded the minimum damage rating. The genotype ICPL 98009 recorded maximum grain yield (471 kg ha−1) while minimum yield was recorded in ICPL 98007 (270 kg ha−1). The genotypes ICPL 98009, ICPL 98013 and ICPL 98014 were found least susceptible to pod borer.
