THE EFFECTIVENESS OF NEEM LEAF EXTRACT (Azadirachta Indica Juss) IN ETHANOL AS REPELLENT FOR THE BITES OF AEDES AEGYPTY

Abstract

Background : Aedes aegypti mosquito is the primary vector of dengue fever is common in tropical
countries, including Indonesia. Control measures with eradication of vector / adult mosquitoes using
plant neem (Azadirachta indica Juss) containing compound azadirachtin, salanin, nimbin and
nimbidin which can inhibit the appetite of adult mosquito Aedes aegypti. The purpose of this study to
determine the effect of neem leaf extract (Azadirachta indica Juss) on the growth and development of
the mosquito Aedes aegypti.
Methods : This research method using descriptive experimental (purely experimental test). Samples
of neem leaf extract and as an indicator is adult mosquito Aedes aegypti. The consentration of neem
leaf extract used 0% (g/ml) (control), 10% (g/ml), 20% (g/ml), 30% (g/ml), 40% (g/ml), 50% (g/ml),
60% (g/ml), and excuted the experiment twice.
Results : Frequency bite of Aedes aegypti was 210 at concentration of 10%, 195 at concentration of
0%, 164 at concentration of 30%, 138 at concentration of 40%, 129 at concentration of 50%, 88 at
concentration 60%.
