Abstract

Management of spotted stem borer, Chilo partellus (Swinhoe) by the use of resistant cultivars is being developed at ICRISAT. Different cultivars show resistance based on several mechanisms, one of which affects the establishment of first instar larvae in the plant whorl. However, it has been found that low establishment is a factor associated with resistance only in some cultivars and not in others. A number of physical and chemical plant factors are associated with preferential establishment of the young larvae in the leaf whorl. Among the physical characteristics, erect leaves and curled leaf bases are involved in larval establishment. Detailed chemical analysis of surface extracts showed that the concentration of one compound in the wax is related to resistance at this stage and assessment of physical and chemical plant characters has been used to predict resistance.
