%X The fruit fly, <em>Bactrocera dorsalis</em> (Diptera: Tephritidae) is one of the most important pests in all mango-producing areas, particularly in West Africa. In Senegal, <em>O. americanum</em> leaves have been used for several years to control this fly. However, to our knowledge, no chemical studies have been carried out. Thus, the aim of this study is to determine the chemical composition of the essential oil of <em>O. americanum</em> leaves collected in Senegal and Gambia. The essential oil obtained by hydrodistillation of these leaves is analyzed by GC/FID and GC/MS. Yields of essential oils from <em>O. americanum</em> leaves are 3.84% and 2.13%, respectively. Analysis of these essential oils by GC/FID and GC/MS allowed the identification of 23 compounds representing almost 100% of the total compositions. These essential oils are mainly dominated by methyleugenol (72.0% and 75.8%, respectively). Other components in significant percent are trans-<em>¦Â</em>-caryophyllene (13.9% and 13.0%, respectively), germacrene D (4.1% and 3.7%, respectively), <em>¦Â</em>-elemene (3.3% and 0.9%, respectively). Due to the high methyleugenol content, this study explains the attractive potential of <em>O. americanum</em> towards B. dorsalis. In perspective, we plan to evaluate the attractive effect of the essential oil and leaf powder of <em>O. americanum</em> against <em>B. dorsalis</em>, a real pest of mango orchards in Senegal.
