Optimization of a phenotyping system in sugarcane to evaluate different strategies against Diatraea saccharalis (Fabricius)* [Full subscriber]

Abstract         Sugarcane borer Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae) is the most important sugarcane pest in Tucumán, Argentina.  Older larvae (L3, L4) bore into the stalks, disrupting the physiological integrity of the plant, facilitating fungi and bacteria colonization which indirectly reduce yield and quality of sugar.  The aim of the present work was to optimize a sugarcane plant-infestation method with D. saccharalis under controlled conditions to help to evaluate different strategies to manage the pest.  Different numbers of neonate larvae were placed in the leaf whorl of sugarcane seedling (two-month-old) of cultivars TUC 95-10, TUC 03-12 and LCP 85-384.  Ten larvae…
