Introduction: This study evaluated the chemical characterization, larvicidal activity and molluscicidal activity in front of the snail transmitting schistosomes (Biomphalaria glabrata) of the essential oils of Alpinia zerumbet and Cymbopogon citratus (DC.) Stapf. The essential oils (EOs) were extracted by hydrodistillation, with chemical characterization through Gas Chromatography coupled to mass spectrometry (GC-MS). The physical-chemical parameters were determined according to the Brazilian Pharmacopoeia. The toxicity test followed the bioassay with Artemia salina Leach, the EOs approved in this assay followed to evaluate their biological properties. Methodology: for molluscicidal activity, the methodology recommended by the WHO was performed, and the LC50 of the EOs was performed for their action in the face of the snail obtained by the Reed&Muench method. Both EOs showed low toxicity, and thus were evaluated for the biological properties larvicidal and molluscicidal. Alpinia zerumbet EO showed molluscicidal activity with LC50 of 40.63 mg·L-1 and Cymbopogon citratus EO 33.94 mg·L-1. Results: Both EOs showed larvicidal and molluscicidal potentials against the organisms tested, showing satisfactory results for their action. The results indicate that the evaluated EOs are composed of substances that promote and encourage their application due to their potential for molluscicidal and larvicidal biological activity.
