Ten different maize germplasm were evaluated for their relative resistance to maize stem borer Chilopartellus (Swinhoe). Several biological parameters of C. partellus viz., larval and pupal survival, larvaland pupal recovery, larval and pupal weights and percent pupation and plant parameter i.e. leaf injuryrating (1-9) were used to study the germplasm susceptibility level. Larval weight (10th, 18th and 25th Daysafter Artificial Infestation) and pupal weights were significantly lower on the germplasm viz., BML-7and HKI-323 as compared to the germplasm namely, HKI-1128 and HKI-193-1 indicating thegermplasm susceptibility level. The pupae obtained from the relatively resistant germplasm were founddeformed with lower weight indicates maximum antibiosis resulted from rearing the larvae on resistantgermplasm. The adverse effects on biological parameters were found more pronounced in larval andpupal weight, and larval survival and percent pupation of C. partellus. Relatively higher percent pupationand larval survival were observed on highly susceptible germplasm HKI-1128 and HKI-193-1 ascompared to resistant ones BML-7 and HKI-323. Not Available |
