The present study was carried out to evaluate the larval efficacy of Dalbergia sissoo and to identify its most potent part as a larvicide. Different solvent extracts obtained from flowers, seeds and branches of D. sissoo along with market procured shisham oil were tested for their larvicidal potential against An. stephensi larvae. There was an overall lethal effect of different extracts of D. sissoo against vector mosquito larvae. On the basis of the LC50 values, the most potent extract of the larvicidal nature was screened and analyzed by GC-MS technique (Gas Chromatography-Mass Spectrography). Hexane extract of flowers was found to be most effective with LC50 value of 55.328 ppm and LC90 value of 180.319 ppm. LC50 and LC90 values of methanol extract of seeds, acetone extract of branches and oil of shisham were 121.517 and 300.695 ppm; 114.829 and 341.972 ppm; 128.739 and 232.543 ppm respectively. The gas chromatography of the flowers extract of D. sissoo revealed 62 chemical constituents19 of which contributed more than 1% of the total area of the chromatogram. These constituents may be further tested for their larval efficacies and their potential could be exploited for the development of safer and effective plant based mosquito larvicide.
