Introduction: Dengue hemorrhagic fever is one of the most common infectious diseases in Indonesia. The vector of this disease is Aedes aegypti (Ae. aegypti). Dengue hemorrhagic fever can be controlled by a few measures, one of them is using insecticide. However, frequent use of chemical insecticide could lead to resistance and is harmful to non-target organisms. One of the solutions for this problem is the use of bioinsecticide derived from lemongrass (Cymbopogon citratus or C. citratus) leaves extract. Methods: The design of this study is true experimental post-test only control group. The population used are adult Ae. aegypti mosquitoes. For each experiment, 10 mosquitoes are required and given the extract of C. citratus in 2%, 10%, and 20% concentrations, and negative control respectively.The lethal effect of the extract is observed in 10, 30, 60 minutes and 6, 12, 18, 24 hours. Results: There is a significant difference in the lethal effect of Ae. aegypti mosquitoes with variations in duration of exposure to the C. citratus leaves extract (p = 0.007), but no significant difference with variations in extract concentration given (p = 0.281). Conclusion: C. citratus leaves extract has bioinsecticidal effect on Ae. aegypti mosquitoes. The optimal result of mosquito mortality is achieved by using the extract in 20% concentration with duration of 12 hours.

Dengue hemorrhagic fever (DHF) is a disease that is found in some tropical and subtropical regions. This disease is caused by dengue virus and is transmitted to humans through the bite of the Aedes aegypti mosquito. the solution taken in controlling DHF is to break the life cycle of the Aedes aegypti mosquito. Vector control is generally carried out using synthetic larvicides, namely abate / temefos, but the use of abate can cause residues, environmental pollution, poisoning and resistance of the eradicated vectors so that natural larvasides from plants are needed namely temulawak rhizome (Curcuma xanthorrhiza Roxb.) for vector control. The purpose of this study was to determine whether temulawak rhizome extract was effective or not in killing Aedes aegypti larvae. This research method includes larva collection, identification and maintenance of mosquitoes, determining sample size, making extracts and testing effectiveness. This study used a control and experiment group with 3 repetitions in the minutes to 15, 30, 45, 60 and 1440 (24 Hours). The control group was positive control using abate and negative control using aquades while the eksperiment group used extract of temulawak rhizome (Curcuma xanthorrhiza Roxb.) with concentrations of 0.6%, 0.8%, 1%, 1.2% and 1.5%. The results of this study indicate that the temulawak rhizome extract (Curcuma xanthorrhiza Roxb.) effective as larvicides because at the lowest concentration 0.6% can kill 100% Aedes aegypti larvae.

DHF (Dengue Hemorrhagic Fever) is a serious problem in Indonesia. DHF disease control has been applied so far, one of which is the use of larvacide temephos (abate). However larvacide is a chemical insecticide that has a negative impact on human health and causes resistance. Therefore in this research, biological control is carried out by utilizing entomopathogenic fungi as a larvacide. The purpose of this study was to determine the effectiveness of entomopathogenic fungi isolated from Ae aegypti larvae. Against the death of Ae. Aegypti mosquito larvae with the moist chamber method. This study used a completely randomized design (CRD) with a factorial pattern and performed two repetitions. Factor A is a type of fungi with 3 levels, namely A1: Aspergillus sp1, A2: Aspergillus sp2, and A3: Syncephalastrum sp. Factor B is a dilution with 7 levels, namely B0: Control, B1: 100 (without dilution), B2: 10-1, B3: 10-2, B4: 10-3, B5: 10-4, B6: 10-5 with every treatment was applied in 2 repetitions. Observations were made 24 hours after treatment for 3 days. Data were analyzed using analysis of variances (anova) and continued with the Least Significant Difference Test (LSD) at 5%. The results indicate that fungi isolates are the most effective in killing Ae. Aegypti mosquito larvae is Aspergillus sp1 and Aspergillus sp2 on the treatment of spores without dilution. Key words: DHF; larvacide; Aedes aegypti; Entomopathogenic Fungi.

<p><em>Aedes aegypti mosquito is a type of mosquito that can carry dengue virus that causes dengue fever. This mosquito has the potential to transmit dengue hemorrhagic fever (DHF). DHF is a disease characterized by sudden fever, bleeding both on the skin and in other parts of the body and can cause shock and death. So in order to reduce the impact of the disease, there are several ways that must be taken. One way of controlling that is done to reduce the population of aedes aegypti mosquitoes is by reducing larval growth by using a solution of papaya leaves as larvacide. Papaya leaves contain tannins of 0.12%. So it is possible to kill larvae. The purpose of this study was to analyze the differences in the average mortality of untreated instar 1 aedes aegypti larvae and treated with a solution of distilled papaya leaves, amounting to 0ml / 100ml (X0), 1ml / 100ml (X1), 2ml / 100ml (2) , 4ml / 100m (X3) with observations every 6 hours for 24 hours. This study is a true experimental study with the presentation of the data analyzed using the kruskal wallis test on spss. The results showed that there were differences between the control group and the treatment group (p &lt;0.05). The most significant difference occurred in the 4ml / 100ml (X3) group which had the highest mortality than the other groups. So the higher the concentration and the longer the duration of exposure, the higher the mortality rate in the larvae. </em></p>
