Article Synopsis
  • The study explored the insecticidal properties of various compounds from the plant Artocarpus lacucha, traditionally used in Southeast Asian medicine.
  • The research involved extracting and testing these compounds against Spodoptera litura larvae, identifying that the ethyl acetate extract was the most effective.
  • The compound catechin, isolated from this extract, showed the highest toxicity and affected important enzymes in the larvae, indicating its potential as a natural insecticide, though further research is needed for field application.

Essential oils are well known to act as biopesticides. This research evaluated the acute toxicity and synergistic effect of essential oil compounds in combination with cypermethrin against Spodoptera litura Fabricius (Lepidoptera: Noctuidae). The effects of distillation extracts of essential oils from Alpinia galanga Zingiberaceae (Zingiberales) rhizomes and Ocimum basilicum Lamiaceae (Lamiales) leaves; one of their primary essential oil compounds 1,8-cineole; and linalool were studied on second-instar S.

Spodoptera litura (Fabricius) is economically important in many countries. Many biopesticides have been developed and studied to control this pest species; however, few natural products from marine organisms have been studied for their pesticidal efficiency. This study compared the acute contact toxicity of solvent extracted from the viscera of Holothuria atra and isolated triterpene glycoside compounds on third-instar S.
