Garlic (Allium sativum) As Natural Larvacides For Aedes Aegypti Larvae

Application larvicides synthetic in the long term could be expected to cause resistance, so it required an effort of larvicides alternative, one of them is with natural larvicides derived from plants to toxic insects but harmless to humans and the environment. Garlic contains allicin, and diallyl sulfide has bactericidal and flavonoid that act as a respiratory inhibitor to insects. The objective is to determine the effectiveness of garlic against Aedes aegypti larvae mortality. We did experimental studies with Aedes aegypti larvae as research subject which is tested with garlic solution with concentration and a certain amount of time. The larvaes were divided into 6 groups: concentrations of 10%, 15%, 20%, 25%, 30%, and control (without treatment). Each group contains 20 larvaes observed every 3 hours, 6 hours, 9 hours, and 12 hours with 3 repetitions. Garlic solution is effective if Aedes aegypti larvae death more than 50%. The data were analyzed based on guidelines for laboratory and field testing of mosquito larvicides by WHO. At concentration of 10% larvae mortality by 30%, concentration 15% larvae mortality 45%, concentration 20% larvae mortality 75%, concentration 25% larvae mortality 85%, and concentration 30% larvae mortality of 90% while in control group there is no dead larvae. Effective garlic solution to kills larvae at concentrations of 20%, 25%, and 30%. We recommended using garlic solution with high concentrations to killing larvae at containers
