Background: Dengue is still a major vector-borne disease problem in the world. It is caused by infection with the Dengue virus, which can be spread through a vector in the form of the Aedes aegypti mosquito. One of the ways to reduce the incidence of dengue infection is by controlling vectors. Aim: This study aims to analyze the effectiveness of vector control of the Aedes aegypti mosquito on the dengue incidence in Southeast Asia. Methods and findings: This study was a systematic review that examines articles with experimental research designs and cluster randomized controlled trials. The scope of this research area is limited to Southeast Asian countries during 2012-2021. There are 333 articles obtained from two sources: PubMed and ScienceDirect, by using certain keywords. Furthermore, articles were selected based on inclusion and exclusion criteria, so that 31 articles were obtained. A total of 6 articles that met the inclusion criteria were then selected for further analysis. Three journals that discussed the output in the form of the Larva Density Index (LDI) showed a decrease with significant results. Two journals that discussed biological control (Bacillus thuringiensis israelensis) got significant results in decreasing Pupal Density (PD). The two journals on chemical control (permethrin) that discussed the outcome of the presence or absence of IgG seroconversion show insignificant results. Conclusion: All control methods are considered effective. However, among the three vector control methods studied, the control with Bacillus thuringiensis israelensis is the most effective method.

Introduction: The control program for Dengue Hemorrhagic Fever (DHF) outbreaks prioritizes controlling the mosquito vector population. One way of biologically controlling mosquitoes that is safer and more environmentally friendly is fish as natural predators of larval and pupae stage mosquitoes. One fish tested in this study was Rosy Barb (Pethia conchonius). Objective: This study aimed to compare the male and female fish predation ability of rosy barb (P. conchonius) in Aedes aegypti larval and pupal stages. Methods: This study is a laboratory experiment with a post-test-only design and five replications. One aquarium holds one litre of water, one fish, and 25 Ae. aegypti larval/pupa tails. Fish testing begins at 09.00 WIB in the morning. Fish predation was timed until the fish consumed all larvae and pupae. Results: The mean time of predation of male P. conchonius to larvae was 12.03 minutes, and pupae were 2.83 minutes. The mean time of predation of female P. conchonius on larvae was 11.70 minutes, and pupae were 4.28 minutes. The results of the independent sample t-test equal variance assumed statistical test showed that male and female fish had mosquito larvae feeding times that were not significantly different (p\> 0.05). Male and female fish had mosquito pupa feeding times that were not significantly different (p \> 0.05). Conclusions: Rosy barb fish (P. conchonius) has the potential as a natural predator of Ae. aegypti larval and pupal stages.

Introduction: The mosquito species of Ae. aegypti is a vector of arthropod-borne diseases such as dengue haemorrhagic fever. Acetylcholinesterase (AChE) enzyme in Ae. aegypti that encoded by the ace-1 gene. Damage in the ace-1 gene as target of insecticide lead to the loss of the normal structure and function of AChE. However, damage in the ace-1 gene remains uncharacterised. The main aim of this study was to find out the point mutations of ace-1 gene in Ae. aegypti larvae treated with methanolic extract of Citrus hystrix leaves. Method: This experiment using a completely randomized design with two treatment groups. A container containing lethal concentration 50 of methanolic extract of C. hystrix leaves, and a control group containing only water with 0.5\% Tween-20. Each group contained 50 third instar larvae of Ae. aegypti, and each group was repeated four times. Observation was performed for 24 h for the number of survived and dead larvae. Survived and dead larvae were collected prior to the DNA extraction, PCR, electrophoresis, and sequencing. The sequences of those two groups were then compared to determine the point mutations using genetyx ver 12. Results: The PCR products of both groups showed clear bands of 500-600 bp long. Furthermore, the presence of the mutation was confirmed by sequencing the PCR product of ace-1 between each treatment group. The survived larva in the extract-treated group showed more point mutation compared with that of dead larvae. Conclusions: This first report indicated that many mutations in the form of deletions and insertions in nitrogenous bases and different amino acid variations of the ace-1 gene of third instar larvae of Ae. aegypti after 24 h treated with methanolic extract of C. hystrix leaves than those in control group.

Objective: The purpose of this study is to investigate the larvicidal and pupicidal activity of Clerodendrum philippinum leaf extracts against disease causing vectors Anopheles stephensi and Aedes aegypti. Methods: Five different concentrations (200, 300, 400, 500 and 600 ppm) of leaves were prepared by using aqueous (distilled water), ethanol, methanol, n-hexane, chloroform and tested for both the activity. The LC50 and LC90 values of leaf extracts were determined with the help of probit analysis. Results: Among the different extracts of leaf screened, the ethanol extract of C. philippinum was recorded the highest larvicidal and pupicidal activity of 100 \± 1.9 \% (1st instar) and 58 \± 0.8 \% at 600 ppm concentration for controlling An. stephensi, respectively. Similarly for Ae. aegypti, 97 \± 1.2 (1st instar) and 51 \± 0.5 (pupa) percentage of inhibition were achieved for the same solvent extracts of the leaf which were maximum than others. Moreover, the values of LC50 and LC90 clearly indicate that the activity of both larvicidal and pupicidal are not only solvent extracts dependant but also depend on their concentration. Conclusion: The obtained data highlight the potential role of ethanolic extracts of C. philippinum for controlling An. stephensi and Ae. aegypti mosquitoes at their larval and/ pupal stages of development.

Objective: The bio-efficacy of Tephrosia purpurea leaf extract and bacterial insecticide, Bacillus sphaericus larvicidal activity was assessed against the first to fourth instars larvae of Aedes aegypti, under the laboratory conditions. Methods: The plant material was shade dried at room temperature and powdered coarsely. T. purpurea and B. sphaericus show the various concentrations of larvicidal and pupicidal activity against various instars larvae of A. aegypti. Results: The LC50 of T. purpurea against the first to fourth instars larvae were 139.24, 176.24, 219.28, 256.27, and 326.29 ppm and the 480.72, 541.21, 580.34, 672.20, and 762.80 ppm, respectively. B. sphaericus against the first to fourth instars larvae the LC50 values were 46.16, 56.23, 69.82, 80.81 and 96.12 ppm and the LC90 values 141.68, 172.46, 184.21, 193.31 and 218.16 ppm, respectively. However, the combined treatment of T. purpurea + B. sphaericus (1:2) material shows highest larvicidal activity of the LC50 values 80.08, 82.21, 88.00, 92.21 and 98.16 ppm; The LC90 values of 108.39, 118.71, 136.75, 149.02 and 153.24 ppm, against A. aegypti in all the tested concentrations than the individuals and clearly established that there is a substantial amount of synergist act. Conclusion: The present study reported that both T. purpurea and B. sphaericus materials could serve as a potential larvicidal agent. Since, A. aegypti is a container breeder vector mosquito this user and eco-friendly and low-cost vector control strategy could be a viable solution to the existing dengue disease burden. Therefore, this study provides first report on the mosquito larvicidal activity the combined effect of T. purpurea leaf extract and B. sphaericus against as target species of A. aegypti.
