Esse estudo avaliou a produtividade dos criadouros de Aedes aegypti (Linnaeus) e Aedes albopictus (Skuse) no município de Parati através dos dados da vigilância entomológica obtidos pelos métodos preconizados pelo Programa Nacional de Controle da Dengue (PNCD). O maior número de pupas de A. aegypti foi coletado nos ralos (31%), garrafas e latas (23%); e com A. albopictus o maior número foi nas garrafas, latas (24%) e vasos de planta (21%). Do total de pupas obtidas, 84,3% e 79,3% das pupas de A. aegypti e A. albopictus respectivamente foram coletadas em pequenos reservatórios: garrafas, vasos de plantas, pneus, bromélias, oco de árvores e ralos. Essas produtividades contradizem a literatura e podem ser explicadas pelas limitações de acesso aos grandes reservatórios e falha na capacitação dos agentes. Esse estudo chama atenção para a importância que os pequenos reservatórios podem ter na densidade do vetor no meio urbano nacional e conclui que a metodologia de vigilância entomológica usada tem sido ineficaz para identificar os grandes e mais produtivos criadouros. Essa conclusão sugere que essa ineficácia pode ser um fator importante pelos insucessos no combate a dengue no Brasil. Evaluation of Breeding Productivity from Surveillance Data for Aedes aegypti (Linnaeus) and Aedes albopictus (Skuse) in Parati, RJ, Brazil Abstract. This study evaluated the pupa-productivity of the entomologic surveillance according methodology used by the official Program for Dengue Control in Brazil (PDCB) for Aedes aegypti (Linnaeus) and Aedes albopictus (Skuse) in Parati, RJ, Brazil. The highest number of A. aegypti pupae were found in drains (31%), bottles and cans (23%); and the highest number of A. albopictus pupae were found in bottles and cans (24%), and plant vases (21%). Of the total pupae identified 84.3% and 79.3% of A. aegypti and A. albopictus respectively were collected in small receptacles: bottles, plants vase, tires, bromeliads and tree holes. These productivities are not supported by literature and can be explained by the restrictions of access for the bigger receptacles and lack of training of the agents. The study points out the importance which the small receptacles can have on vector densities in urban environment despite of their productivity and conclude that the entomology surveillance methodology for dengue used in PDCB has no efficacy to identify the bigger and more productive receptacles. This conclusion suggests that this inefficacy can be an important factor for the failures on dengue vector control in Brazil.

Background In Malaysia, dengue remains a top priority disease and usage of insecticides is the main method for dengue vector control. Limited baseline insecticide resistance data in dengue hotspots has prompted us to conduct this study. The present study reports the use of a map on the insecticide susceptibility status of Aedes aegypti and Aedes albopictus to provide a quick visualization and overview of the distribution of insecticide resistance. Method and results The insecticide resistance status of Aedes populations collected from 24 dengue hotspot areas from the period of December 2018 until June 2019 was proactively monitored using the World Health Organization standard protocol for adult and larval susceptibility testing was conducted, together with elucidation of the mechanisms involved in observed resistance. For resistance monitoring, susceptibility to three adulticides (permethrin, deltamethrin, and malathion) was tested, as well as susceptibility to the larvicide, temephos. Data showed significant resistance to both deltamethrin and permethrin (pyrethroid insecticides), and to malathion (organophosphate insecticide) in all sampled Aedes aegypti populations, while variable resistance patterns were found in the sampled Aedes albopictus populations. Temephos resistance was observed when larvae were tested using the diagnostic dosage of 0.012mg/L but not at the operational dosage of 1mg/L for both species. Conclusion The present study highlights evidence of a potential threat to the effectiveness of insecticides currently used in dengue vector control, and the urgent requirement for insecticide resistance management to be integrated into the National Dengue Control Program.

Dengue Vector Control

Owing to increased epidemic activity and difficulties in controlling the insect vector, dengue has become a major public health problem globally. The prevention and control of dengue rely mainly on vector control methods. A systematic review was conducted using four databases (PubMed, Cochrane, Google Scholar and Scopus) and a manual search of the reference lists of the identified studies. Data from included studies were extracted, analyzed. Applying all inclusion and exclusion criteria 23 articles was included. Further relevant articles using this keywords Aedes dengue breeding habits housing and community intervention were selected. Eight studies combined community participation programme with dengue control tools. Findings of the published literature indicate that at baseline, almost half the respondents did not know that dengue is serious but preventable, or that it is transmitted by mosquitoes. The analysis showed that dengue vector control is carried out by vertically structured programmes of national, state, and local administrative bodies through fogging and larval control, without any involvement of community-based organizations, and that vector control efforts were conducted in an isolated and irregular way. The most productive container types for Aedes pupae were cement tanks, drums, and discarded containers. Evidence that community-based dengue control programmes alone and in combination with other control activities can enhance the effectiveness of dengue control programmes is weak. This review demonstrates a paucity of reliable evidence for the effectiveness of any dengue vector control method. Standardized studies of higher quality to evaluate and compare methods must be prioritized to optimize cost-effective dengue prevention. Clear best practice guidelines for the methodology of entomological studies should be developed.

Dengue vector control is still relying on fogging using insecticides with solar solvents. This causes pollution due to the odors generated and residues left in the environment. It is necessary  to look for alternative insecticides that no longer use solar as a solvent but use water such as Gokilath-S50EC. In this experiment, we tested the effectiveness of Gokilath-S50EC (d,d-trans-syphenotrin 50 g/l) with the aim to see the insecticidal efficacy of Aedes aegypti known as DHF vector. The sample test mosquito used is Ae. aegypti which comes from Pangandaran Lokalitbangkes as many as 25 females. Test mosquitoes were exposed to insecticides for 3-5 seconds with a method of fogging. The experimental results showed that mosquitoes tested fainting in the first 30 seconds after exposure to insecticides. The same results were shown when the solvent was added polyethylene-glycol (PEG). This time trial also measured droplet diameters at 1.0 mm and 1.2 mm nozzle with or without PEG. The test results showed that PEG increased the percentage of droplets of ≥ 50 µm in air and made the insecticide reach even further. Gokilath-S50EC insecticides are effective in killing Ae. aegypti by using water solvents, the addition of PEG will increase the reach of insecticides but not affect the effectiveness of insecticides.

Indonesia is known as a dengue-endemic country with an increasing number of cases. Appropriate dengue vector control efforts are needed to control the transmission of this disease effectively and efficiently. Botanical larvicide is one type of dengue vector control which is expected to be an alternative as a substitute for chemical larvicides. The purpose of this study was to determine the effect of red betel  (Piper crocatum)infusion on the mortality of Ae. aegypti. True experimental design with post-test only with control group was used in this study. The test was carried out by dividing the sample into two groups, including the red betel infusion group and the control group (with aquadest), the observations were carried out for 24 hours. The results of the study showed that the larvacide test of red betel leaf infusion had an effect on 12 to 24 hours, and there was an increase in mortality of Ae. egypti for 24 hours. The humidity of the test room is one of the factors that can affect the results of the study. Abstrak Indonesia dikenal sebagai negara endemis dengue dengan jumlah kasus yang terus meningkat.  Appropriate dengue vector control efforts diperlukan untuk mengendalikan penularan penyakit ini secara efektif dan efisien.
