“…Larvae are found feeding on immature cobs, silks and tassel and severe infestation result in stunted plant growth and appearance of cob and tassel at one place (Reddy et al, 2003) [10] pink stem borer, Sesamia inferens is major insect pest of maize in Peninsular India during Kharif and Rabi. The loss primarily due to S. inferens in Kharif varies from 60 to 81.7% and in Rabi (winter) it varies from 25.7 to 78.9% (Sekhar et al 2009) [11] .…”

The germplasm/varieties of maize raised during Rabi season of 2020-2021 at oil seed farm, Kalyanpur and insectary department of entomology, C. S. Azad University of Agriculture And Technology Kanpur (U. P.). The soil of experimental field was study loam with homogenous average fertility level. The topography of the site of experiment was fairly prevented from the water logging condition. Geographical location of Kanpur district falls at 26.29° North longitude and 80.18 °C East longitude at an altitude of 125.9 m from the sea level. Observation on pink stem borer was recorded at 15 days intervals on five randomly selected plants, started from sowing to harvesting of the crop. In study we found that Azad Kanti, Azad PC-3, Azad BC-14, REHBC 1413-2, and Azad BC-5 were found resistant and HPC-5 more susceptible against stem borer, Chilo partellus.

“…HPR can effectively complement other components of IPM to reduce the losses due to PSB damage in maize. In previous studies, variability in resistance to PSB has been observed among maize inbred lines based on Leaf Injury Rating (LIR) at the early whorl stage ( Sarup et al., 1978 ; Sekhar et al., 2008 ; Sekhar et al., 2016 ; Lakshmi Soujanya et al., 2019 ; Lakshmi Soujanya et al., 2020 ). Apart from LIR, observations on stem tunneling is also been reported as one of the most important parameter which can be considered to identify the resistant genotypes against PSB ( Malvar et al., 2008 ).…”

Host Plant Resistance (HPR) is the most important component for sustainable management of insect pests. The purpose of the present work was to understand the role of various morphological and biochemical factors as defense mechanism and their interaction on different biological parameters attributed to survival and development of pink stem borer (PSB), Sesamia inferens Walker in maize. The resistant and moderately resistant genotypes (DMRE 63, CM 500 and WNZ Exotic pool) suffered least leaf injury rating (LIR), dead hearts (DH%), percentage stem tunneling (ST%), number of entry/exit holes (E/EH) and showed deleterious effects on biological parameters of pink stem borer as compared to susceptible ones (CM 202 and BML 6). Resistance index among the genotypes varied from 0.11 to 0.46. The variation in morphological traits such as number of nodes, internode distance and stem diameter could not distinguish all the resistant genotypes from that of susceptible genotypes in terms of its mean value. Higher levels of biochemical constituents, viz., p-Coumaric acid (p-CA), ferulic acid (FA), acid detergent fibre (ADF) and acid detergent lignin (ADL) were observed in resistant genotypes compared to susceptible ones. Antibiosis was expressed in terms of reduced pupal weight when fed on WNZ Exotic pool, whereas larval weight and larval survival affected when fed on DMRE 63. Higher concentration of p-CA content in pith of resistant maize genotypes prolonged the pupal period of pink stem borer. Higher concentration of p-CA and FA contents in rind reduced the adult emergence, as they showed significant negative correlation between them. The larval period was prolonged with higher levels of ADF and ADL contents in maize genotypes either in rind or both rind and pith as both ADF and ADL content showed a significant positive correlation with the larval period. The Pearson correlation analysis of most of the biochemical constituents revealed significant negative correlation with damage parameters. The correlation coefficients between p-CA with DH (%), ST (%) and E/EH were r= -0.9642**, r= -0.9363**, and r= -0.9646**, respectively. Similarly, the correlation coefficients between FA with DH (%), ST (%) and E/EH were r= -0.9217*, r= -0.9563**, and r= -0.9434**, respectively and ADF with DH (%), ST (%) and E/EH were r= -0.9506**, r= -0.9611**, and r= -0.9709**, respectively. The study confirms that stem damage parameters can also be used as selection criteria along with LIR to identify resistant genotypes against pink stem borer. Based on the correlation analysis it was concluded that resistance to pink stem borer in maize is the result of interaction of several morphological and biochemical traits rather than a single factor. The findings obtained from the present study can be utilised in pink stem borer resistance breeding programmes to enhance and diversify the basis of resistance.
