| Summary: | Three Curcuma species. Curcuma aeruginosa (pink and blue ginger). Cu. aromatica (aromatic turmeric), and Cu. xanthorrhiza (giant.curcuma), were selected for investigation of mosquito repellent activity. In a laboratory study, a 95% ethanol extract of each plant was tested for repellent activity of Aedes togoi on human volunteers. Only Cu uromatica extract showed repellency against Ae. togoi with EDsa and EDos values of 0.061 and 1.55 mg/cm2, respectively. It also provided biting protection for 3.5 b when applied at a concentration of 25 g% The ethanolic extract of Cu. aromatica was therefore chosen for further repellent activity under field conditions, where it had a protective effect against Armigeres subalbatus. Culex quinquefasciatus, and Cx. tritaeniorhynchus. The ethanol-extracted Cu. aromatica did not cause dermal irritation when applied to human skin. No adverse effects on human volunteers were observed 2 mo after application. Therefore. Cu aromatica extract can be applied as an effective personal protection measure against mosquito bites. |
