According to a study published by "Parasitology research", extracts of Cestrum nocturnum were tested for larvicidal activity against second, third, and fourth instar larvae of Aedes aegypti. The LC(50) values of the extracts in different solvents were less than 50 ppm, specifically ranging between 15.40-38.50 ppm against all tested larval instars. Qualitative analysis revealed a predominance of saponins in C. nocturnum, which were partially purified and confirmed through thin-layer chromatography and biochemical tests. Larvicidal stability was evaluated at five constant temperatures of 19°C, 22°C, 25°C, 28°C, and 31°C against fourth instar larvae. These partially purified saponins showed potent mosquito larvicidal activity against the fourth instar larval form. Toxicity studies against the fish Poecilia reticulaata showed almost nil to meager toxicity at LC(50) and LC(90) doses.
