Abstract

We studied the effects of different maize genotypes on developmental biology, and larval and adult behaviors of spotted stem borer, Chilo partellus. The test maize genotypes had signifi cantly lowerpupal weight, larval survival, adult emergence and fecundity as compared to susceptible check, Basi Local. There was signifi cant increase in premating period, decrease in pre-oviposition and oviposition periods, decrease in numbers of egg clusters and eggs per cluster, and increase in egg incubation period in C. partellus on these test genotypes as compared to those from susceptible check, Basi Local. The studies on establishment and feeding behaviors of C. partellus larvae on different maize genotypes revealed that the neonate larvae took longer time to establish on the resistant maize genotypes, and the establishment on resistant maize genotypes was also signifi cantly lower than on the susceptible genotype. Thus, the maize genotypes viz., CPM 13, CPM 15, CPM 18 and CPM 8 impart detrimental effects on the growth, development and progeny production of C. partellus and can be utilized in breeding to derive C. partellusresistant varieties of maize.
