This research aims to determine the effectiveness of Belimbing wuluh (Averrhoa bilimbi
L.) against Aedes aegypti mosquito larvae mortality. The method used in this research was an
experimental method using a Completely Randomized Design (CRD) which consist of 5
treatments and 4 replications. Parameters measured were mortality of Aedes aegypti larvae
during 96 hours exposed, LC50 values and toxic response of Aedes aegypti larvae. Other
parameters are temperature and pH medium during 96 hours exposed. Result showed that
belimbing wuluh has mortality power against Aedes aegypti larvae. At concentration of 3%
larvae’s mortality achieve 100% at 48 hours exposed, whereas at concentration of 2%, 1.3% and
0.8% larvae’s mortality were 87.5%, 67.5% and 35% at 96 hours exposed. LC50 values exposed
at 24 hours, 48 hours, 72 hours, and 96 hours were 2.14%, 1.35%, 1.34%, and 0.6%. Aedes
aegypti larvae’s toxic response showed agile movement, slowing in time, siphon’s position
parallel to the surface of the medium, and color of larvae’s body becomes gray. Concentration
suggested to be applied to the environment is 0.6% during 96 hours exposed.
