Analysis and larvicidal activity of tinospora rumphii boerl (Makabuhay) stem against mosquito larvae
Year: 2025
Type: article
Abstract: This study investigates the larvicidal potential of Tinospora rumphii Boerl (Makabuhay) stem extract against Aedes aegypti larvae, assessing its viability as an eco-friendly insecticide. Phytochemical analysis confirmed the presence of bioactive compounds, including alkaloids, steroids, and saponins, known for their insecticidal properties. The stem extract was tested at concentrations of 1%, 5%, 10%, and 20%, and mortality rates were recorded at 24, 48, and 72 hours. ANOVA revealed significant differences in mortality rates across concentrations, with the 20% extract causing 98% mortality. Pearson’s correlation analysis demonstrated a strong positive relationship between phytochemical concentration and larvicidal activity. Eco-toxicity tests showed minimal adverse effects on non-target organisms, and the extract exhibited biodegradability. These results support T. rumphii as a promising natural alternative to chemical insecticides for mosquito control. Future studies should focus on isolating active compounds and optimizing application methods for broader use in integrated pest management strategies.
