Larviciding is an effective supplementary tool for malaria vector control, but the identification and accessibility of aquatic habitats impedes application. Dissemination of the insect growth regulator, pyriproxyfen (PPF), by gravid Anopheles might constitute a novel application strategy. This study aimed

To analyze the chemical compositions of Dalbergia odorifera essential oils extacted by CO2-supercritical-fluid-extraction (SFE-CO2) and steam distillation extraction (SD). The essential oils of Dalbergia odorifera were extracted by steam distillation extraction and SFE-CO2. The chemical components were separated and analyzed

A previous study reported that when cedrol (odorant) is inhaled directly through the lower airway of the trachea, it decreases the sympathetic nervous activity and blood pressure in totally laryngectomized subjects (Umeno et al., 2008). In the present study, totally
