<p>The <em>Aedes aegypti</em> mosquito can develop an immune system against the insecticide used. Control efforts with the use of insecticides are no longer effective if the target insects have become resistant. So there needs to be an effort to overcome the insect resistance that is targeted. Citronella grass is an herbal plant that can be used as an ingredient in vegetable pesticides. The leaves and stems are distilled to produce essential oil known as citronella oil. This research is about studying the effects of citronella oil against the resistance of the vector carrier for dengue fever, namely <em>Aedes aegypti. </em>The detection of citronella essential oil (<em>Cymbopogon nardus</em> L.) by Thin Layer Chromatography showed a reduction in UV<sub>254</sub> visualization (Rf 0,68). The resistance test showed that the mortality percentage of adult mosquitoes <em>Aedes aegypti</em> exposed to 0.03% alphacymethrin was 73,7% resistant criteria (&lt;90%). The mortality percentage of adult mosquitoes <em>Aedes aegypti</em> exposed to Alphacypermethrin (0,03%) and citronella oil was 2,5% each; 5%; 7,5% and 10% with treatment time 15 respectively, namely 18,7%, 50,7%, 70,7% and 82,7%; the treatment time of 30 minutes consecutively is 62,7%, 89,3%, 96% and 97,3% and the treatment time is 60 minutes respectively, namely 93,3%, 98,7%, 98,7% and 100%. There was an increase in the percentage of mosquito deaths exposed to the combination of alphacypermethrin and citronella oil, compared to those without citronella oil, this indicates that mosquitoes are more susceptible and resistance has decreased due to exposure to citronella oil. <strong></strong></p>

Introduction: Indonesia as a tropical country is vulnerable to mosquito-borne diseases like dengue fever, chikungunya, and zika by Aedes aegypti mosquito. Various efforts have been made to eradicate mosquitoes, one of which is by fogging. But this method only eradicates adult mosquitoes and its smoke can also have a bad impact for human health. Therefore, a variety of herbal plants began to be used as biolarvacide, including basil plants (Ocimum basilicum). Methods: This is an experimental research by comparing the lethal effect between concentration and time. In this experiment there were 10 larvas used for each concentration, which were 0,4%, 0,7%, 1,0%, 1,5%, and 2,0%. The lethal effect arising in larval groups is observed every 1 hour in the first 6 hours, and subsequently every 3 hours until 24 hours after exposure. Results: With one way ANOVA test, the result is p=0,012 (p<0,05) this shows that there is a significance difference between the different concentrations and the lethal effect of A.aegypti larvae. With Friedman test, the result is p=0,000 (p<0,05), this shows that there is a significance difference between the different time of exposure of the extract and the lethal effect of A.aegypti larvae. Conclusion: Leaves extract of O.basilicum has lethal effect as biolarvacide against A.aegypti larvae. The higher concentration and the longer time of exposure to O.basilicum extract, increases the lethal effect of A.aegypti larvae.

Kata kunci : Ekstrak, Cymbopogon nardus, larvasida, Aedes aegypti Abstract Control of mosquitoes as the main vector of transmission of DHF can only be done by breaking the chain of transmission through mosquito control. Mosquito control can be carried out at the larval stage by using biolarvasides made from natural materials, one of which is by using a crude extract from the citronella plant (Cymbopogon nardus). This research is to find out the effectiveness of citronella extract as larvae of Aedes aegypti larvae instar III and IV. This research is a pure experimental study using a complete random design. The larvae used were instar larvae III and IV, with the treatment of citronella extract concentration of 20%, 30%, 40%, and 50% in 250 ml of water. In this study, there was a control i.e. aquades which did not add any solution. Observation of larvae death was done at 1 hour, 2 hours. 4 hours, 12 hours, 24 hours and 28 hours with replication 4 times. Data on larval mortality were used to calculate LC50 and LT 50 values using Probit regression analysis. The results showed that citronella extract was effective in killing 50% of the population of test larvae with LC50 values at a concentration of 36.48% and the time needed to kill 50% of the population of test larvae was 10,450 hours.Key words:  Extract, Cymbopogon nardus, larvasida, Aedes aegypti

Effectiveness Of Various Concentrations Of Lemongrass Leaf Extract Lotion (Cymbopogon nardus) As Repellent Of Aedes aegypti Mosquitoes. Dengue Hemorrhagic Fever (DHF) is a disease caused by dengue virus which is transmitted through the bite of the Aedes aegypti mosquito. Vector control efforts that are popular in the community are using chemical insecticides. The use of insecticides can cause mosquito resistance and cause poisoning in humans. Then effective controls need to be developed to avoid these impacts. Safe control of health and environmentally friendly is to use natural repellent derived from plants, one of which is lemongrass leaf (Cymbopogon nardus). The purpose of this study is to know the effectiveness of various concentrations of lemongrass leaf extract lotion (Cymbopogon nardus) as repellent of Aedes aegypti mosquitoes. This type of research is an experimental laboratory with the research design of The Posttest - Only Controlled Group Design. The research method by hand control and treatment is presented in a cage containing 25 Aedes aegypti mosquitoes for 6 hours with repetition 10 times each hour. The results showed that a concentration of 20% had an average protective capacity of 82.8%, a concentration of 40% had an average protective capacity of 95.0%, an concentration of 80% had an average protective capacity of 98.1% and lotion repellent from chemicals with the brand "X" has an average protection capacity of 88.6%. The results of the Kruskal Wallis analysis proved significant with p = 0.003 α (0.05), so there were significant differences in the protective power. The conclusion of the study was that the lemongrass leaf extract lotion was effectively used as a repellent of Aedes aegypti mosquitoes at a concentration of 40% and 80% because the protective power value 90% even though it had been used for 6 hours.

Dengue fever is an infectious disease caused by dengue virus and is transmitted by Aedesaegypti and Aedes albopictus. In the year 2010 there had been 150.000 cases in Indonesia and thenumber of deaths was 1317. Transmission of this disease can be prevented using plant essentialoils to be applied as repellents. This study was aimed at investigating the differences betweenjasmine essential oil (Jasminum sambac) and leaf basil (Ocimum basilicum) as repellents againstAedes aegypti mosquito.This is a quasi-experimental study using a non-randomized control group pretest-posttestdesign. Subjects were female Aedes aegypti mosquitoes, 25 mosquitoes on each test. Thematerials used were jasmine flowers essential oil at 40% concentration and basil leaves essentialoil at 90% concentration. As much as 10 replications were performed during the study.Independent SamplesT Test was carried out for analyzing the data.The average number of mosquitoes that came in contact with human hand that had beengiven jasmine flowers essential oil at 40% concentration were 3 mosquitos and basil leavesessential oil at 90% concentration was one mosquito. There was no significant difference betweenthe number of Aedes aegypti mosquitoes that come in contact with human hand applied withjasmine flowers essential oil at 40% concentration and basil leaves essential oil at 90%concentration (p =0.000; 0=0. 05).The conclusion was 90% concentration of essential oils of basil leaves, having 3.32%linalool as an active ingredient had a better ability as a repellent against Aedes aegypti comparedto jasmine flowers essential oil at 40% concentration which has 2.9% linalool as an activeingredient. Essential oil of basil leaves can be applied as a substitute for synthetic chemicalrepellent topically every 8.5 hours.Keywords: jasmine essential oil, basil leaf; Aedes aegypti
