Biopesticidal Efficacy of Tephrosia purpurea and Derris elliptica Against Spodoptera litura

Key Points

Derris elliptica achieved 94% mortality at 20% concentration, while Tephrosia purpurea reached 90% mortality.
Both plant extracts were effective, indicating their potential as biopesticides for pest control.
The extracts were prepared using ethanol maceration at different concentrations for testing.
Findings support the use of these plants in integrated pest management programs.

Abstract

AbstractIn order to search plant-based biopesticides, ethanol leaf extracts of Tephrosia purpurea and Derris elliptica were evaluated against Spodoptera litura larvae. The leaf extracts were prepared using ethanol maceration and tested at four concentrations (5–20%). Mortality was recorded after 48 hours. Results demonstrated clear concentration-dependent larval mortality, with D. elliptica achieving 94% mortality at 20% concentration, while T. purpurea achieved 90%. The performance of both plants may be attributed to their rotenone content. The findings indicate that both species possess strong insecticidal potential suitable for Integrated Pest Management (IPM) programs.
