Utilization of Basil Leaf Extract as Anti-Mosquito Repellent: A Case Study of Total Mosquito Mortality (Aedes aegypti 3^rd Instar)

Abstract

This study aims to determine the most effective concentration of extract that kills the larvae in the third instar Aedes aegypti, knowing the value of LC50 and LC90 anthen knowing the value of LT50 and LT90 of forest basil leaf extract (Ocimum sanctum). Research is using a completely randomized design with factorial, and the first factor is forest basil leaf extract with 5 level concentrations, there are 0.3%, 0.6%, 0.9%, 1.2%, 1.5%, and 0% as control, whereas the second factor is observation period that began after the death of the larvae. Observations were made up to 4320 minutes. The results showed the influence of forest basil leaf extract against third instar larvae mortality of Aedes aegypti, and the most effective concentration of basil leaf extract to kill the larvae was 1.5%. LC50 values of this study was 0.97%, and for the LC90value was 1.42%. Value of LT50and LT90 of this study is 5,71 hours or 342,31 and 17,02 hours or 1021.22 minutes. The conclusion of this study is basil leaf extract forest affect mortality third instar larvae of Aedes aegypti, and the most effective concentration of extract was 1.5%.

“…Incidence Rate (IR) atau angka morbiditas DBD di tahun 2016 juga meningkat dari tahun 2015, yaitu 50,75 menjadi 78,85 per 100.000 penduduk, meskipun Case Fatality Rate (CFR) atau angka kematian mengalami penurunan dari 0,83% di tahun 2015 menjadi 0,78% di tahun 2016. (Husna et al, 2019;Angelina & Rudatin, 2019).…”

Impact of Four Plant Extracts on Bactrocera dorsalis a Pest on Fruits

“…It is clear from their results that plant extracts are effective on insects. Various studies have examined the lethal concentration (LC) and lethal dose (LD) of these plant extracts for insect like rice weevil [15]; Spodoptera litura [16]; mosquito [17]; termites [18]; Callosobruchus maculatus [19]…”

The Efficiency of Ethanolic Extract of Ocimum basilicum Leaves and Flowers agiainst Mosquito Larvae

“…Ocimum basilicum L -belongs to the family Lamiaceae -is used globally in folk medicine [6]. The Aedes aegypti, showed high sensitivity to Ocimum basilicum L leaf extract with concentrations of 0.3%, 0.6%, 0.9%, 1.2%, 1.5% [7]. Basal leaf powder, when extracted by ethanol, becomes more toxic to insects.…”
