Abstract: Out of 16 plant species tested for mosquito larvicidal activity, the extract of 4 plants could induce 100% mortality of larvae. The results also show that the extract of Lantana camera 1 (pink and yellow coloured flower), L. camera 2 (red flowered), Coriandrum sativum and Eryngium foetidum were the most toxic extracts against the larvae. L. camera 1 and C. sativum showed its pronounced activity after 6 hrs. of treatment where as E. foetidum showed its activity after 24 hrs. and L. camera 2 after 48 hrs of treatment. Though highly aromatic Hyptis suaveolens extract has least activity, which is only 10% after 48hrs. The extract of Triumfetta rhoimboidea has no activity against the larvae
