Standardization of maize genotype for the rearing of maize spotted stem borer, Chilo partellus on natural host

Abstract

A total number of five genotypes namely CML-165, CML-169, CML-373, CML-186 and HKI-586 were evaluated for their nutritional significance on the basis of feeding and survival of the immature stages of maize spotted stem borer, Chilo partellus (Swinhoe). The results under this study revealed that genotype CML-186 followed by HKI-586 were superior in the term of larval, pupal survival while in the case of feeding, maximum feeding was done in CML-186 which was followed by genotypes HKI-586 and CML-165 and they were found at par in larval feeding. The results showed the significant importance of genotype CML-186 in rearing of maize spotted stem borer on natural host. In all the above tested genotypes, no any genotype was found to be having any significant adverse effect on larval population of test insect.
