abstract
The laboratory studies on the effect of resistant and susceptible maize genotype on the growth and development of Sesamia inferens was studied in poly house, Agriculture college campus, IGKV, Raipur (C.G.) on HQPM-1 (resistant hybrid) and Sugar-75 (susceptible hybrid). The percentage pupation, moth emergence and viability of eggs parameters were more in Sugar-75 and as compared to HQPM-1. The period of development from larva to adult emergence was prolonged in case of resistant genotype HQPM-1 i.e. 35.84 days. The growth index was higher on susceptible genotype Sugar-75 which recorded 1.68, whereas the growth index was 1.48 in the resistant genotype HQPM-1. When the larvae reared on susceptible genotype Sugar-75 the developmental period was recorded 34.90 days. The results appear that resistant genotypes might have certain growth inhibiting factors, which retarded the development of S. inferens larvae.
