PAPAYA LEAVES EXTRACT EFFECTIVENESS TEST (Carica papaya L) AS A LARVACIDINE Aedes aegyptiINSTAR III

Abstract

The Aedes aegypti mosquito is a vector of dengue hemorrhagic fever which has a major role in the transmission of the disease in Indonesia. Mosquito vector control is expected to have an impact on decreasing the vector population of the Aedes aegypti mosquito so that it is no longer significant as a disease transmitter. Therefore, natural larvicides are used, one of which is papaya leaf (Carica papaya L) which contains alkaloid compounds, tannins and flavonoids which have a larvicidal effect. This research is experimental to see the killing power of papaya leaf extract (Carica papaya L) against Aedes aegypti larvae and to determine the LC50 and LC90 of papaya leaf extract against Aedes aegypti larvae. The sample size used was 800 larvae with 4 repetitions in each treatment group. Observation time was carried out 24 hours. The measured data was the treatment of papaya leaf extract against Aedes aegypti larvae with concentrations of 0.5%, 1%, 1.5%, 2%, 2.5% and 3% and abate as a positive control or distilled water as a negative control. that there is a difference in the mean mortality of Aedes aegypti larvae between groups which is statistically significant with a value of p0.000 ≤ α (0.05). Probit analysis results found that papaya leaf extract (Carica papaya L) with a concentration of 0.591% was able to kill 50% of Aedes aegypti larvae for 24 hours. Papaya leaf extract (Carica papaya L) with a concentration of 2,873% was able to kill 90% of Aedes aegypti larvae for 24 hours
