Abstract: The larvicidal activity of essential oil extracted from Glycosmis pentaphylla (Retz.) was evaluated against three mosquito species Anopheles stephensi, Aedes aegypti and Culex quinquefasciatus. Fifty five compounds were identified through GC-MS analysis of the essential oil and showed bioactive compounds. The major compounds were biocyclo (6.1.0) non-1-ene (18.93%), benzaldehyde oxime (15.66%) caryophyllene oxide (7.47%) aromadendrene (0.30%). Five different logarithmic concentration of essential oil was evaluated. The Lethal Concentration 50 (LC50) and Lethal Concentration 90 (LC90) for 24 hr and 48 hr exposure against A. stephensi larvae were 13.79 ppm, 5.85 ppm and 45.06 ppm 30.51 ppm respectively. These properties suggest that G. pentaphylla oil has a potential and valuable larvicidal compound. This plant which causes high mortality at lower doses could be considered as potential plant for bioprospecting.
