Antibiosis studies in kharif-2016 with seven selected genotypes and kharif-2017 with 8 genotypes, respectively. Higher food ingested mean was observed in genotypes G5P22 (6.14) and lowest food ingested mean was observed in CAT- 47 (3.26) and in genotypes EC333879 were observed highest food ingested (7.58). Minimum weight gain of larvae in genotypes CAT-47 (0.49) and maximum in genotypes EC333902 (1.27) was recorded. Maximum weight of frass was observed in susceptible check JS -335 (1.75) and minimum weight of frass were observed in genotypes CAT-139 (0.74), whereas the lowest weight of frass in genotypes (0.32). The larvae reared on CAT-139 found the lowest value of AD (81.82%) and mean highest value of AD (084.77%) in JS 335 and EC333879 found the highest value of AD (1.05%). Mean lowest value of ECI (14.78%) found genotypes CAT-47 and mean highest value of ECI (23.14%) and mean highest value of ECD (47.54) found in genotypes EC333902, whereas the low value of ECI (8.05%) and ECD (7.71%) found in genotypes EC333879.
