Methanolic extract of Artemisia ludoviciana "Estafiate" against Spodoptera frugiperda larva

Abstract

Artemisia ludoviciana contains several medically important metabolites, but few studies have been reported on its effects on insects of agricultural importance. This article aimed to know the biological effects of a methanolic extract of A. ludoviciana on neonatal larvae of Spodoptera frugiperda, where column chromatography was obtained to fractionate the crude oil and mass gas chromatography to identify metabolites, the extract, and the 90:10 mobile phase showed low mortality of about 30% at a concentration of 1 mg/mL, but a weight loss in neonatal larvae of more than 50% was lost, confirming a significant antifeedant activity. GC-MS analysis revealed the presence of terpenoids such as limonene, thujone, camphor, borneol, and borneol acetate, which are associated with an insecticidal and antifeedant activity. Therefore, the methanolic extracts of A. ludoviciana can be a friendly alternative for insect pest control.
