The effectiveness of arabica coffee ( Coffea arabica L) grounds on mortality and growth of Aedes aegypti Larva

摘要

Background: Control of Aedes aegypti mosquito by using synthetic insecticides has potential effect toenvironmental pollution and increase the resistance of target vectors. It is needed to search the propermethods in controlling Aedes aegypti which is environmentally friendly.Materials and Methods: This study used coffee grounds as inhibiting factor in mortality process andinhibiting the growth of Aedes aegypti larva. This study was an experimental design, conducted in JuneAugust2016 in the laboratory of Environmental Health, Polytechnic of Health Banda Aceh. The doseswere 28/liter, 30g/liter, 31g/liter, 33g/liter, and 34g/liter. The mortality data were analyzed by ANOVA,followed by Least Significant Difference (LSD) test and probit test. Growth data were analyzed by usingGI (Growth index) and RGI (Relative growth index).Results and Discussion: The results showed that the grounds of arabica coffee was capable of causingthe death of Aedes aegypti larva (p=0.00). The treatments with coffee ground also caused a decrease inGI and RGI values, which means that it inhibited the growth of larva.
