Different Silicon Application Sources and Factors Influencing Mandibular Wear in Sugarcane Early Shoot Borer, Chilo infuscatellus Walker

Abstract

AbstractSilicon (Si) can improve plant resistance to herbivorous insect attack. Early shoot borer (ESB), is one of the most solemn lepidopterans borers on sugarcane in India. Even with insecticide application, management of this pest is difficult. The management requires a fresh new approach. As a result, the current study aims to determine the effect of silicon on the early shoot borer, Chilo infuscatellus Walker, through biophysical factor analysis and mandibular wear documentation. When sugarcane leaves were treated with calcium silicate at 1000 kg/ha, scanning electron microscopy revealed the presence of silicified cells and trichomes, as well as increased cell wall thickness, silicon content, and waxes content. Furthermore, larvae of an early shoot borer fed silica-treated plants showed a complete wearing of mandibles as compared to untreated check.
