<![CDATA[Spodoptera litura is a polyphagous pest that causes serious damage to various agricultural commodities. Control methods that still rely on synthetic pesticides negatively influence the environment and health, necessitating more environmentally friendly control alternatives. This study aims to determine the efficacy of ginger extract (Zingiber officinale var. amarum), which contains shogaol compounds, on the mortality of third instar S. litura larvae. The study was conducted experimentally using a one-factor completely randomized design (CRD) with six treatment levels: a positive control (fenite 150 OD), a negative control (Aquades), and ginger extract concentrations of 2%, 4%, 6%, and 8%, each with four replicates. Mortality tests were conducted using the topical application method and observed for 72 h. Data were analyzed using ANOVA, Tukey's test, and probit analysis to determine the LC₅₀, LC₉₀, LT₅₀, and LT₉₀ values. The results showed that ginger extract treatment significantly influenced the mortality of S. litura larvae (Sig. = 0.032). The 8% concentration resulted in the highest mortality of 82.5% at 72 h and the highest efficacy value of 82.5%, approaching that of the positive control. The LT₅₀ and LT₉₀ values were 37.15 hours and 64.81 hours, respectively, while the LC₅₀ and LC₉₀ values were 0.815% and 23.134%. The extract treatment also caused morphological changes in the larvae, including changes in body color, shrinkage, and tissue damage. Emprit ginger extract containing 6.8% shogaol, particularly at an 8% extract concentration, has the potential to serve as an effective environmentally friendly biopesticide in controlling S. litura.]]>
