“…Larval mortality increased at higher extract concentrations, whereas in the negative control, there was no larval mortality because it did not contain ethanol extract of E. indica leaves. In this study, LC50 and LC90 were obtained at concentrations of 466.907 g/L and 868.42 g/L, different from research conducted [20] that at a concentration of 0.9093 g/L, E. indica leaf extract had the effect of killing 50% of the Aedes aegypti larvae population in 24 hours. Differences in outcomes E. indica leaf larvicide can be influenced by the location where the E. indica plant grows.…”

This study aimed to ascertain the larvicidal and mortality activities of crude ethanolic extract derived from Euphorbia indica against larvae of Aedes aegypti and Culex vishnui. A preliminary test was conducted in order to ascertain the mortality rate ranging from 10% to 90%. The concentrations for the final test encompassed a range from 0.0998 g/L to 1.498 g/L alongside a single negative control. The LC50 and LC90 values of the ethanolic extract derived from Euphorbia indica leaf were determined to be 466.90 g/L and 868.42 g/L, respectively. The larvicidal effect of Euphorbia indica leaf is attributed to a chemical component that acts as a positive allosteric modulator of the GABA pathway. The collected data was subjected to analysis using the Kruskal-Wallis statistical test. Probit analysis was employed to examine the LD50 and LD90 values. The minimal lethal dose that resulted in 100% mortality of Culex vishnui larvae was determined to be 0.2 g/100 ml (p=0.01). The probit analysis yielded LD50 and LD90 values of 0.01 g/100 ml and 0.06 g/100 ml of aquades in Culex vishnui, respectively. The larvicidal efficacy of the dose was determined to have an LD90 value of 0.06 g/100 ml of aquades, but the LD50 value was found to be 0.01 g/100 ml of aquades. The assessment of Culex vishnui treatment involved comparing the number of mortality larvae and the number of living larvae from each treatment to the control group. In conclusion, the ethanolic extract derived from the leaves of Euphorbia indica exhibits promising potential for developing mosquito larvicides.

“…The results of this study were consistent with those reported by Sneha (Sneha & Preet, 2016) that during the test, essential oils affected the test larvae which decreased the frequency of larval movements. Decreased frequency of larval movements is the first sign that a material has larvacidal properties (Torres et al, 2014) The decrease in the frequency of larval movement is the effect of one of the compounds in kaffir lime peel essential oil namely monoterpene. Most essential oils of kaffir lime peel are monoterpene.…”

DHF vector control still uses chemicals. Long-term application can lead to target insect resistance and environmental pollution so that a better alternative is to use biological insecticides because it is environmentally friendly. The aim of the study is to identify the effect of kaffir lime peel essential oil on the behavior and mortality of Ae.aegypti larvae. The research method used was completely randomized design of three treatments and three replications. The results show that larval behavior after administration of kaffir lime peel essential oil at a concentration of 103 ppm decreased the frequency of movement, the larvae were unable to rise to the surface of the water after 1.5 hours. The results of the research were tested with probit analysis at a confidence level of 95% LD 263,552 ppm. The analysis result in one-way ANOVA for the number of differences in the number of dead larvaes, with the value obtained sig. = 0.000, which means that there is a significant influence on differences in doses of papaya seeds powder solution used against the death of Ae. aegypti larvaes. Kaffir lime peel contains essential oils that can be used as biological insecticides in DHF vector control.

Penggunaan larvasida kimiawi yang digunakan untuk mengontrol aedes aegypti telah menimbulkan populasi yang resistensi, sehingga dibutuhkan dosis yang lebih tinggi. Namun hal ini memiliki efek toksik bagi manusia, hewan, serta lingkungan. Larvasida alami merupakan larvasida yang dibuat dari tanaman yang mempunyai kandungan beracun terhadap serangga pada stadium larva dan tidak menimbulkan efek samping terhadap lingkungan. Penelitian ini bertujuan untuk mengetahui kemampuan dari ekstrak daun mengkudu, daun papaya dan kombinasi keduanya dalam mengendalikan larva Aedes aegypti. Jenis penelitian yang digunakan dalam penelitian ini adalah eksperimental laboratorium dengan desain Rancangan Acak Kelompok (RAK). Objek penelitian adalah larva Aedes aegypti sebanyak 400 larva. Uji dibagi menjadi 4 kelompok dengan dua kali pengulangan. Analisis yang digunakan adalah analisis univariat dan bivariat. Hasil penelitian menunjukkan terdapat perbedaan jumlah kematian larva pada pengulangan I dan II sedangkan rata-rata PH air, suhu air dan kelembaban udara tidak menunjukkan perbedaan yang signifikan. Disimpulkan bahwa kombinasi ekstrak daun mengkudu dan daun pepaya lebih efektif sebagai larvasida alami untuk kematian larva Aedes. Disarankan melakukan analisis probit untuk mendapatkan nilai toksisitas (daya racun) terhadap serangga percobaan dan pengujian terhadap insektisida kimiawi sebagai pembanding (kontrol) terhadap insektisida alami.
