Abstract
Kunzea arnbigua (Smith) Druce (Myrtaceae) is an Australian native plant, commonly
known as tick bush. The essential oil of the plant has been proposed as a potential mosquito repellent.
Commercial K. arnbigua oil was analyzed by gas chromatography-mass spectrometry (GC-MS) and
its composition compared with that of oils from two individual K. ambigua plants and citronella oil.
K. ambigua oils were studied for their repellency against Aedes aegypti L. Formulations of three
different K. arnbigua essential oils (30% vol:voi) were tested for repellency to mosquitoes using human
volunteers. One oil was compared \vith citronella and N,N' -diethyl-:3-methylhenzamide (deet) for
repellency. Oil formulations were also tested for repellency with and without the addition of 5%
vanillin. The formulation containing commercially produced K. ambigua oil had a mean complete
protection time (CPT) of 49 ± 24 (SD) min. All the K ambigua formulations had comparable
repellency to 40% citronella. However, the 60% citronella formulation showed higher repellency than
the 40% K. arnbigua formulation. The addition of 5% vanillin did not increase the repeliency of K.
arnbigua oi1. Botll K. arnbigua oil and citronella were significantly less repellent than deet. The K
arnbigua essential oil formulations should not be advocated for use as repellents in regions prone to
mosquito-borne disease.
