Dengue Hemorrhagic Fever (DHF) is a disease caused by Dengue virus. The disease is spread rapidly in the territory of Indonesia by Aedes aegypti mosquito as the vector. Using Moringa Aloifera leaf extract as a natural larvacide is an attempt to control the disease. This study aims to determine the effect of Moringa Aloifera leaf extract on the mortality of Aedes aegypti larvae. Moringa Aloifera leaf extract is obtained by maceration. The experimental design was divided into negative control groups containing aquades, positive controls containing abate and sample treatment groups. Phytochemical test and UV-Vis spectroscopic quantitative test to identify active compounds. A total of 20 Aedes aegypti larvae were put into a glass containing a solution of distilled water, abate solution and sample solution. Observations are made every 2 hours for 24 hours. The results showed that Moringa leaf extract solution could kill larvae at LC50 3953.17 ppm and LT50 18.98 hours. The mortality rates of larvae at each concentration were 1000 ppm, 5.25 units / 2 hours; 2000ppm, 5.28 units / 2 hours; 3000ppm, 5.91 units / 2 hours; 4000 ppm, 7.18 units / 2 hours, and 5000 ppm 8.63 units / 2 hours. The results showed that Moringa Aloifera leaf extract can kill Aedes aegypti larvae because they contain alkaloids, tannins and flavonoids.Keywords: larvacide, Moringa, Aedes aegypti larvae

SummaryCooling techniques have several applications for reproduction in aquaculture. However, few studies have sought to create protocols for cooling and cryopreservation of Macrobrachium amazonicum embryos. Thus, the objective of this work was to verify the survival of M. amazonicum embryos and the correlation between embryonic volume and mortality of M. amazonicum embryos after cooling. Embryo pools were collected from three females and divided into two treatment groups: dimethyl sulfoxide (DMSO) 3% and ethylene glycol (EG) 0.5%, both of them associated with 2 M sucrose. Positive and negative control groups consisted of seawater 10%. Aliquots of 10 µg of embryos were placed in Falcon® tubes containing a cryoprotectant solution and submitted directly to the test temperature of 2°C for 2 and 6 h of cooling. Further analysis of survival and embryonic volume were performed under a stereoscopic microscope. Data were subjected to analysis of variance (ANOVA), and means were compared using the Tukey test at 5%. The highest embryonic survival rate was observed after the shortest storage time for both the DMSO 3% and the 0.5% EG groups, with survival rates of 84.8 ± 3.9 and 79.7 ± 2.8%, respectively. There was a reduction in survival after 24 h, with the DMSO 3% group presenting a survival rate of 71.7 ± 6.6%, and the EG 0.5% group, 66 ± 6.9%. Survival showed a statistically significant difference when compared with the positive controls after 2 h and 24 h of cooling, with 99 ± 0.5% and 95.8 ± 1.5% survival rates, respectively. There was no significant statistical difference in the embryonic volume, but it was possible to observe a change in the appearance of the embryos, from a translucent coloration to an opaque white or brownish coloration, after 24 h in incubators. Thus, it can be concluded that survival is inversely proportional to storage time and that, although there was no change in the embryonic volume after cooling, a change in the appearance of embryos could be observed.

The Difference

Effort to control DHF (Dengue Hemorrhagic Fever) vectors without toxic substances by using natural and enviromentally friendly materials was natural repellent made using plants that were widely available in the community.Many types of plants contain  various secondary metabolite compound substances that have the potential to be used as natural insecticides, especially as repellent of the Aedes Aegypti mosquito. The research needs  to be done to determine the effectiveness of basil leaves, citronella leaves, clove leaves and betel leaves as a repellent against Aedes Aegypti mosquitoes. This research method was an experiment in the laboratory. The materials used for this research were basil leaves, citronella leaves, clove leaves, and betel leaves. The extracted leaves were then made lotions with certain formulas, tested as a natural repellent against Aedes Aegypti mosquitoes. The concentrations used were 20%, 40% and 80% as well as negative control (0%) and positive control (brand x lotions). The number of mosquitoes used in the study were 25 x 4 treatments = 100 mosquitoes. The replication or repetition was done 10 times. To find out the difference in the number of Aedes Aegypti mosquitoes that perch on the hands of probandus which has been smeared with basil leaf, citronella leaf, clove leaf and betel leaf extracts uses Anova Statistical tests and kruskal wallis. To see the difference between concentrations was tested with LSD or Mann-Whitney test. The calculation result of the number of Aedes Aegypti mosquitoes that perch before and after applying the lotion, the lowest was the lotion of citronella leaf extract 0% (11); 20% (2); 40% (1); 80% (1); The highest protection capacity of extract lotion is citronella leaves with concetrations of 20% (81,1%); 40% (95%), 80%(98,2%); There were no significant differences between the lotion concentrations of 20% and 80%, while the concentration of 40% is significantly different. Then the LSD follow-up test finds that the protective capacity of lotion of clove leaf extract is negative and citronella leaf extract is positive. The most effective protection capacity against Aedes Aegypti mosquitoes was lotion of citronella leaf extract with concentration of 40% (95%) and a concentration of 80% (98,2%), proven by the value of protection capacity that is stable even though it has been used for up to 6 hours and can exceed the protection capacity of lotion x (90,3%). It is reccomended that further research needs to be developed to optimize the lotion of citronella leaf extract 40% and 80% with orgonolaptic test of color, aroma, stickness and comfort of its use.

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.

Indonesia is the country with the highest cases of dengue fever in Southeast Asia. The WHO estimates a 50–100 million dengue infections worldwide every year. Dengue Hemorrhagic Fever (DHF) is transmitted through the bite of female Aedes mosquitoes infected with the Dengue virus. Mosquitoes Aedes aegypti is the main vector of the dengue virus. At the time, there is no cure for dengue so that the control efforts are focused on breaking the chain of life cycles. One effort to prevent the transmission of the dengue virus is to avoid vector mosquito bites. Repellent can reduce exposure to the bite of mosquitoes infected with the dengue virus. The aim of this study was to determine the effectiveness of the extract of citrus hystrix leaf as a repellent against the Aedes aegypti mosquitoes. This research is a laboratory experimental study with a one-shot case study design. In this study, the extract of citrus hystrix solution was made at a concentration of 10%, 20%, and 30%, and then the extract solution was used as a stock to make a 100-gram base lotion that would be used as a repellent. Repellent effectiveness is seen from the percentage of repellent protection power. The percentage of repellant protection used with the basic ingredients of Citrus hystrix leaf extract at concentrations of 10%, 20%, and 30%, respectively, at 93.33% 94.67%, and 97.33%. The extract of citrus hystrix leaf was found to be effective as a repellent against Aedes aegypti mosquitoes.

ABSTRACTMosquitoes are type of insect that acts as a disease vector. One of them is Culex sp mosquitos which their existence is many around us. In Indonesia there are still a lot of disease cases that caused by Culex sp mosquitos, one of them is filariasis disease. The efforts to control thecurrent population of Culex sp mosquitoes mostly use chemical insecticides. The control becomes difficult because of the resistance to chemical insecticides and adversely affects the environment. This study aims to determine the potential of jackfruit leaf extract as biolarvasida against Culex sp. The type of this study was post test onlycontrolled group design, using 625 larvae Culex sp instar III, divided into 5 groups (negative control group, 0.25% extract, 0.50% extract, 0.75% extract, extract and 1% extract). Observation was performed 24 hoursafter the treatment and counted the number of larvae death.The data were analyzed by Kruskal Wallis test followed by Post Hoc Mann-Whitney U test to determine the killing power of leafy leaf extractusing Probit analysis. The results of data analysis in this study were thedeath rate percentage of larvae after 24 hours treatment was 0% incontrol, 44% in 0.25%extract, 52% in0.50% extract, 60% in 0.75%extract,while in the extract group of 1%, the number of larval deaths was 72%. Itobtained results with significant differencein some treatment groups thatwere concentrations of 0.25% - 1%. Probit analysis showed that LC50 wasat 0.382% concentration.From results of the studyit can be concluded that jackfruit leaf extract(Artocarpus heterophyllus Lamk) was potential as Culex sp mosquitobiolarvacide. So it is necessary to conduct further research on the effectsof compounds that contained in other plant parts such as flowers, stemsand roots which will be expected to have a function asbiolarvasida.Keywords: Leaf Jackfruit, Biolarvasida, Mosquito Culex sp
