“…Hasil analisis uji probit menunjukkan bahwa konsentrasi 586,009 ppm dan 2119,645 ppm dapat membunuh populasi 50% dan 90% (Tabel 5). Hal ini berbeda dengan penelitian sejenis yang dilakukan Kewa et al (2020) mendapatkan nilai LC50 sebesar 0,736 % apabila dikonversi ke ppm maka sebesar 7360 ppm. Menurut Sumihe et al (2014) bahwa semakin kecil nilai LC50 dari suatu sampel maka senyawa bioaktifnya juga semakin tinggi.…”

The Culex genus is widely distributed in Indonesia. It is responsible for disrupting and interfering of human daily activities and also transmitting some diseases for human. Vector control strategies normally involve the use of synthetic larvacide however excessive use causes adverse effect on environmental quality and resistance to larvae. Thus, extract from soursop (Annona muricata L.) leaves may be an alternative sources of larval control agents. The present study reveals the larvicidal effect of methanol extract from soursop leaves against 3rd instar larvae of Culex sp. mortality. Experimental method with Completely Randomized Design (CRD) consisting of 6 treatments (0 ppm, 125 ppm, 250 ppm, 500 ppm, 1000 ppm and 2000 ppm) and 4 replications was carried out with Culex sp. 3rd instar larvae and the larval mortality was recorded after 48 hours since the exposure. Data were analyzed using one way ANOVA which was continued by Tukey HSD and followed by Probit analyze to determine LC50 and LC90. The results showed that the methanol extract of soursop leaves exhibited significant larvicidal activity with LC50 and LC90 values are 586,099 and 2119,645 ppm. The highest concentration increases the mortality rate of larvae. In conclusion, the soursop leaves methanol extract has a larvacide effect on the 3rd larvae of Culex sp.

Controlling the vector by eradicating mosquito larvae is frequently done by spreading Abate powder containing 1% Temephos as a larvicide agent. However, the use of Abate powder will possibly increase pesticide residue contamination in the water. This study aimed to explore the potential use of ethanolic extract from red dragon fruit skin to kill mosquito larvae. An experimental laboratory study was performed to examine the larvicidal activity of ethanolic extract from red dragon fruit skin. Maceration method was used to extract active compounds from the fruit skin. Subsequently, the viscous extract was formulated using the wet granulation method to obtain powder form. The larvicide test was done by comparing the lethal concentration (LC50) of mosquito larvae after treatment using the extract and the reference larvicide agent, 1% Temephos Abate. The treatment groups consisted of four different extract concentrations of 1%, 2%, 3%, and 4%. The LC50 of each treatment groups was then calculated against the negative control group. Phytochemical screening showed that the ethanol extract of red dragon fruit skin contains alkaloids, flavonoids, saponins, triterpenoids, and tannins. The larvicide test on Aedes aegypti mosquito larvae showed that the extract treatment hardly killed the Aedes aegypti mosquito larvae. However, on Culex mosquito larvae, the ethanolic extract of red dragon fruit skin was able to kill mosquito larvae, with LC50 value of of 19.06%. The ethanolic extract of red dragon fruit skin was effective on killing the Culex mosquito larvae but not the Aedes aegypti mosquito larvae.
