Daya Repelen Beberapa Minyak Esensial dan Deet terhadap Culex
Abstract: Diseases transmitted
by Culex can be prevented by using repellent. DEET (N,N-diethyl-m-toluamide),
is an effective repellent, but may cause several toxic effects for certain
users. Therefore DEET substitute must be searched such as essential oils, for
example eucalyptus, clove, and citronella oils, which are safer. The aim of
this study is to compare which oil from these ones is the most effective, to
know whether these oils can be listed in standard repellent against Culex as a
DEET substitute, and also to know the time interval of application needed. The
laboratory study was carried out based on method described by Fradin and Day’s method. Repeated tests were
conducted simultaneously in five cages using repellent treated forearms of
volunteers. The time needed in minutes since repellent application until first
mosquito bite was recorded. The data was analyzed using one way ANOVA and
continued with Duncan analysis using α= 0.01. Highly significant statistical
analysis proved that against Culex, duration of repellent effect of eucalyptus
oil was shorter than clove oil/ citronella oil, and duration of repellent
effect of clove oil/ citronella oil was shorter than DEET. From this study it
is concluded that repellent effect of clove oil/ citronella oil was more
effective than eucalyptus oil and these essential oils can be placed on standard repellent list.
Eucalyptus oil application must be repeated every 123 minutes while clove oil
and citronella oil must be repeated every 287 minutes.
