Minimum webbing due to M. vitrata was recorded in variety H03-41 and maximum in Manak. The webbing was maximum in 3rd date of sowing. The peak larval and webbing of H. armigera and M. vitrata was observed in 40th 43rd, 41st and 43rd and 44th, 47th and 43rd during 1st, 2nd, 3rd and 4th date of sowing, respectively. Significant positive correlation of H. armigera and M. vitrata was observed with maximum temperature, evening relative humidity and rain fall. Significant negative association of M. vitrata webbing was observed with morning and evening average vapour pressure and wind speed. Irrespective of pests and varieties, maximum infestation was found in 2nd date of sowing date of sowing and minimum in 4th date of sowing. Variety AL-201 recorded lowest infestation of all the pests. Pusa-992 recorded highest infestation of H. armigera and M. vitrata, whereas, maximum infestation of pod fly was observed in variety Manak. The maximum pod damage (23.39%) was recorded in 1st date of sowing and the maximum larval survival (2.66), larval weight (16.81 mg/ larva), per cent pupation (83.76%), adult emergence (96.11%) and fecundity (595.54 eggs/ female) was observed in 2nd date of sowing, whereas, minimum pod damage (15.08%), larval survival (1.18), larval weight (10.77 mg/ larva), per cent pupation (40.33%), adult emergence (67.78%) and fecundity (423.25 eggs/ female) was observed in 4th date of sowing. In different sowing dates, the maximum pod damage (21.4%) and larval weight (15.40 mg/ larva) was observed in variety Manak. The maximum larval survival (2.28) and per cent pupation (76.76%) was observed in Paras. The adult emergence was maximum (94.17%) in variety Pusa-992, whereas, the minimum pod damage (15.89%) and larval weight (12.02 mg/ larva) was recorded in variety AL-201. The minimum larval survival (1.56), per cent pupation (50.24%) and adult emergence (75%) was recorded in PAU-881. The interaction between sowing dates, varieties and per cent pod damage was observed significant. The significant difference in the per cent pupation and adult emergence in relation to sowing dates and varieties was observed. In larval survival, per cent pupation and fecundity the significant difference was observed in relation to sowing dates. Significant negative correlation was observed between glandular and non-glandular pod trichomes and pod wall thickness with all three pod borers. Significant positive correlation of all the three pod borers was observed with moisture, crude protein and total soluble sugars, whereas, significant negative correlation of the three pod borers was observed with fat, phenol and tannin content. The glandular and non-glandular pod trichomes, pod wall thickness, tannin, phenol and fat content was comparatively more and total soluble sugar and protein was comparatively less in variety AL-201 which make them moderately resistant against pod borer complex.ensowing, fruits, sowing date, biological interaction, pigeonpeas, animal developmental stages, developmental stages, planting, genotypes, cropsThesis
