A Study of the Effect of Forcipomyia Taiwana Repellents Made of Plant Extracts

The bite of Forcipomyia taiwana (F. taiwana) causes intense pruritus and swelling in sensitive skin. Most commercially available F. taiwana repellents are made of N, N-diethyl-3-methylbenzamide synthetic repellents [; however, using them for a long time influences skins, and the nervous and immune system. This study uses the water extracted Cinnamomum osmophloeum Kaneh and Cymbopogon excavates for the Y-tube test, determining the repellent effect of these two extracts and the influence of water extract time on the difference in their repellent effect.
