Plants extracts contain many essential natural synthesized chemical compounds with considerable potentials for medicinal exploitation and application. There has been a growing concern about the adverse effects of mosquito repellants and the need to search for natural and environment-friendly Mosquito repellants. Synthetic insecticides and their associated toxicity issuesand the growing incidence of insect resistance haveinspired novel insecticides. The present study analyzed the phytochemical extract of H. suaveolensand its effect on mosquito pupa. A total number of pupa (320) was poured into a 200ml glass beaker twenty pupae each per three hours was introduced into a glass beaker containing different extract concentrations (ppm) of Hyptissuaveolens. Twenty pupae were introduced in contrast to a glass beaker containing 100ml of distilled water treated with 1ml of acetone used as treated control. Twenty pupae were introduced into 100ml of distilled water and used as untreated control.The result reveals that Hyptissuaveolenspossesses inhibitory activity against Anopheles gambiae.
