Abstract

Aedes sp is the transmitting vector for Dengue Haemorrhagic Fever (DHF). One of the mosquito
controlling measure is by using insecticides with electric mat. One of bological insecticides which
can be used is nutmeg or Myristicafragans. The extract of the kernels contains tanine and saponine. The purpose of this study was to determine the effect of concentration variation of nutmeg
kernel extract as additional substance for used electric mat against the mortality of Aedes sp.
The study was a quasi experiment with post test only control group design. The collected data
were analysed by using one way anova at 95 % significance level, to determine the effect of the
concentration variation (15 %, 20 %, and 25 %) on the death of Aedes sp. LSD test was then
performed to determine the most effective concentration. The results showed that the three concentrations of nutmeg extract influence the death of Aedes sp (p-value < 0,001), and the most
effective concentration was 25 % with 95 % mosquito mortality.
