Senggigi beach is one of tourist destinations of Lombok island-West Nusa Tenggara. In addition to its beautiful scenery, Senggigi has potential problems in the health field namely Aedes spp., mosquito, which became a dengue vector. This explorative and descriptive research, has been done in June-July 2017 and aimed to observe the bioecology of Aedes spp., mosquito in Senggigi beach. Sampling was done with purposive sampling method, by collecting larvae and adult mosquito Aedes spp., at specified sampling point. The collected samples then identified. The result of the study, two species of Aedes spp., mosquitos were found, there are Aedes aegypti and Aedes albopictus. Breeding habitat of Aedes spp. mosquitos were found in artificial containers. The highest density were 57.5 individuals/100 mL found in the boat habitat and the lowest density were 2 individuals/100 mL in the trash bin. The highest Relative Abundance Index value of Aedes aegypti were 100% in fish pond habitat and Aedes albopictus was 100% in three different habitats (used tire, sterofoam box and used bowl). The selection of Aedes albopictus habitat in clear and dirty water, near the yard of the house with dense vegetation rather than densely populated makes the distribution more widespread. Meanwhile, Aedes aegypti was only distributed in clear water habitats, near densely populated settlements.

Abstract: Dengue Hemorrhagic Fever (DHF) has become a public health problem in Indonesia because of its high prevalence and ability to spread more widely. In North Sulawesi itself Case Fatality Rate of carrying dengue is increasing from year to year. The local village Malalayang has a high potential for spreading this disease. The result of an  entomology survey on adult mosquitos showed that Aedes sp was found in 40 houses of 80 house samples. From these 40 houses we got 71 mosquito samples. From these 71 samples tested and identified, we found three species: Aedes aegypti (30 samples, 42.25%), Aedes albopictus (22 samples, 30.99%), and Culex sp (19 samples, 26.76%). Mosquito density can be seen from the indices of the resting rates, which were 0.375 for Aedes aegypti, 0.275 for Aedes albopictus, and 0.65 for Aedes sp. Key words: density, adult mosquito, Aedes sp., resting rate.   Abstrak: Demam Berdarah Dengue (DBD) merupakan penyakit yang menjadi masalah kesehatan masyarakat di Indonesia karena prevalensinya yang tinggi dan penyebarannya semakin luas.

Acute Viral Infection

Dengue is a mosquito-borne acute viral infection that can develop into a potentially lethal complication known as severe dengue. It is endemic in more than 100 tropical and subtropical countries where the mosquito vectors, predominantly Aedes aegypti and Aedes albopictus, are found. Non-immune travellers are at risk of infection and with the rise in international travel and the availability of cheap holiday packages to endemic countries, many of which are popular tourist destinations, there has been a significant increase in spread of dengue viruses.

Abstract Sugar is an essential source of nutrition for adult mosquitoes to acquire energy. Toxic sugar bait (TSB) provides a promising method for mosquito control by incorporating toxins into artificial sources of sugar (i.e., toxic baits) presented to wild populations. Spinosyns comprise a family of bacterial secondary metabolites with a unique mode of action against the insect nervous system, an appealing environmental safety profile, and potential for incorporation into sugar baits. This research evaluated acute and subacute effects of spinosad (spinosyns A and D) and spinetoram (spinosyns J and L) in sugar meals on survival, fecundity, and fertility of Aedes aegypti and Aedes albopictus. Acute toxicity of spinosyns doubled from 24 to 48 h of assessment, revealing a relatively slow and cumulative action of the formulated spinosyns. Median lethal concentrations at 48 h were lower for spinetoram than for spinosad, lower for Ae. albopictus than Ae. aegypti, and lower for males than females. When exposed to subacute LC50 concentrations of spinosad and spinetoram for 24 h, survival of males and females of both species was diminished compared with controls, fecundity of females was increased, but fertility as measured by hatch rate of eggs was decreased. The formulations may have increased the nutritive value of the sugar meals thereby boosting fecundity, while toxifying embryos, reducing fertility. The inclusion of subacute effects of spinosyns allows assessment of the broader consequences of TSB for adult mosquito control.

Dengue hemorrhagic fever is a public health problem in Pekanbaru. It is transmitted by Aedes aegypti mosquitoes. The use of insecticides to kill vectors is a common practice. It is often used in outbreaks by fogging and daily use of insecticides in households. Household insecticides contain a variety of active ingredients such as organophosphates, carbamates, synthetic pyrethroids, and their combinations. This study aims to determine the sensitivity of Ae. aegypti mosquitoes from various household insecticides. This research was descriptive research by conducting a susceptibility test from World Health Organization. Adult mosquitoes were obtained from the breeding of larvae collected from dengue-endemic areas in Pekanbaru. Three types of insecticides are widely distributed in the market consisting of insecticides X with the active ingredient cypermethrin, transfluthrin, and imiprothrin, insecticide Y containing transfluthrin, and insecticide Z containing pralethrin and sifluthrin. Each insecticide was exposed to an adult mosquito by applying insecticides to filter paper and exposed for 1 hour and observed after 24 hours. The death of mosquitoes in the three types of insecticides is less than 80%. Based on the WHO criteria mortality of less than 80% showed a resistant mosquito. This tendency of resistance is probably caused by long-term continuous use.

Dengue Vectors

Currently, Aedes aegypti, the principal vector of dengue virus in Indonesia, has spread throughout the archipelago. Aedes albopictus is also present. Invasion and high adaptability of the Aedes mosquitoes to all of these areas are closely related to their ecology and biology. Between June 2016 and July 2017, larval and adult mosquito collections were conducted in 43 locations in 25 provinces of Indonesia using standardized sampling methods for dengue vector surveillance. The samples collected were analyzed for polymorphism and phylogenetic relationship using the mitochondrial cox1 gene and the nuclear ribosomal internal transcribed spacer 2 (ITS2). Almost all Ae. aegypti samples collected in this study (89%) belonged to the same haplotype. A similar situation is observed with the nuclear ITS2 marker. Populations of Ae. aegypti characterized few years ago were genetically different. A closely related observation was made with Aedes albopictus for which the current populations are different from those described earlier. Ae. aegypti populations were found to be highly homogenous all over Indonesia with all samples belonging to the same maternal lineage. Although difficult to demonstrate formally, there is a possibility of population replacement. Although to a lower extent, a similar conclusion was reached with Ae. albopictus.

Mosquito index study of three ecologically different ecozones of the Thiruvananthapuram district, Kerala showed sharp difference on the proportionate distribution of Aedes aegypti and Aedes albopictus. Human dengue viremia (HDV) was very high in those ecozones where A.aegypti density was high and HDV was low where A.albopictus was high. In a coastal zone of Thiruvananthapuram city, A. aegypti was the most abundant vector and in a hilly, arid suburban zone, A.albopictus was the abundant vector. In the urban zone both species of mosquitoes showed equal distribution. Study on the circulating serotypes in the serum of HDV by Single step single tube Multiplex PCR showed all the four serotypes viz DENV1, DENV2, DENV3 and DENV4 in patients of Thiruvananthapuram city, which indicated the possibility of Dengue Shock Syndrome, unless there is efficient vector management. Among the four dengue serotypes, Type 1 was the most abundant virus. Abundance of microhabitats in Thiruvananthapuram city, which support A. aegypti may be the reason for high prevalence of dengue fever in the urban zone.

Mosquitoes of Aedes species are vectors of several arboviral diseases which continue to be a major public health problem in Nigeria. This study among other things, morphologically identified Aedes mosquitoes collected from Nsukka LGA and used an allele specific PCR amplification for discrimination of dengue vectors. Larval sampling, BG-sentinel traps and modified human landing catches were used for mosquito sampling in two selected autonomous communities of Nsukka LGA (Nsukka and Obimo). A total of 124 Aedes mosquitoes consisting of five (5) different species were collected from April to June, 2019 in a cross-sectional study that covered 126 households, under 76 distinct geographical coordinates. Larvae was mainly collected from plastic containers 73% (n=224), metallic containers 14% (n=43), earthen pots 9% (n=29) and used car tyres 3% (n=9), reared to adult stage 69.35% (n=86), and all mosquitoes were identified using standard morphological keys. Five (5) Aedes mosquito species were captured; Aedes aegypti 83(66.94%), Aedes albopictus 33(26.61%), Aedes simpsoni (4.48%), Aedes luteocephalus (≤1%) and Aedes vittatus (≤1%). Nsukka autonomous community had higher species diversity than Obimo. Allele specific amplification confirmed dengue vectors, Aedes aegypti and Aedes albopictus species on a 2% agarose gel. Since the most recent re-emergence of arboviral diseases is closely associated with Aedes species, findings of this study, therefore, give further evidence about the presence of potential arboviral vectors in Nigeria and describe the role of a simple PCR in discriminating some. Further entomological studies should integrate PCR assays in mosquito vector surveillance.

O Zika vírus é um arbovírus transmitido pela picada dos mosquitos Aedes aegypti e Aedes albopictus infectados e apresentam como principais manifestações clínicas: febre aguda, exantema, prurido e conjuntivite. Em 2015 causou uma epidemia no Brasil, desencadeando casos de microcefalia em bebês cujas gestantes tiveram a febre da Zika. O Nordeste notificou o maior número de casos. Objetivou-se identificar, a partir de uma revisão integrativa, a relação entre a febre da Zika e a microcefalia. Trata-se de revisão integrativa, realizada a partir de buscas desenvolvidas nas bases de dados da Biblioteca Virtual em Saúde (BVS) e da Scientific Electronic Library Online (SciELO) com publicações dos anos de 2015 e 2016, idiomas português e inglês. Foram encontradas 191 publicações, as quais passaram por um processo de leitura e análise quanto ao atendimento do objetivo e aplicação dos critérios de inclusão. Restaram oito publicações que integraram o corpus desta revisão. Os resultados apontam para uma relação de causa e efeito entre o contato das gestantes com o Zika vírus e o desenvolvimento de microcefalia em seus bebês. Necessita-se de maiores evidências que demonstrem os reais fatores envolvidos nesse processo, como os genéticos, ambientais e até mesmo interferência de outras infecções. Palavras-chave: Zika vírus. Microcefalia. Aplicações da epidemiologia.
