Presence of Arboviral Vector in Tourist Attractions and Public Places: Abundance, Associated Factors and Susceptibility to Temephos.

<b>Background and Objective:</b> <i>Aedes</i> mosquito is a competent vector of arboviruses, mainly dengue, chikungunya, Zika and yellow fever. The high incidence of arboviral infections among travelers indicated the vulnerability of tourist attractions and public places visitors to arboviral infections. This study aimed to determine the presence and population density of <i>Aedes</i> mosquitoes at the places, as well as the susceptibility to temephos larvicide.

Predatory Efficiency of Larvivorous Fish against Mosquito Larvae in Different Water Temperature Levels: Implication in Control Measure of Dengue Vector.

Background: Reduction of the population is the priority effort to control dengue virus transmission including the use of larvivorous fish. Biologically, the predatory efficiency of fish will slow down when the water acidity and temperature change from normal conditions. This study aimed to determine the predatory efficiency of three species of larvivorous fish against the larvae in different water temperatures.

Evaluation of Larvicidal Activity of Extracts Against Larvae.

<b>Background and Objective:</b> The resistance of <i>Aedes aegypti</i> larvae against temephos become an obstacle in controlling the arboviral vector. This condition triggered researchers to investigate the larvicidal activity of phytochemical compounds that are effective, safe, biodegradable and eco-friendly from various medicinal plants. This study evaluated the larvicidal activity of <i>Kaempferia galanga</i> extracts against <i>Ae.

Adherence to Dihydroartemisinin + Piperaquine Treatment Regimen in Low and High Endemic Areas in Indonesia.

After decades of successful artemisinin regimen in combating malaria, its effectiveness has decreased since parasite resistance to the treatment regimen has begun to appear. Adherence to artemisinin combination therapy (ACT) in a population is considered to be the key factor contributing to such resistance phenomenon. Although several studies have tried to demonstrate adherence to several ACT types in a population, only a limited number of studies demonstrated adherence to dihyrdroartemisinin + piperaquine (DHP) regimen.

Susceptibility of Larvae to the Larvicidal Activity of Three Types of Extract.

<b>Background and Objective:</b> The methanol, ethyl acetate and n-hexane extracts of <i>D. elliptica</i> root have high larvicidal activity against <i>Aedes aegypti</i> larvae, the primary vector of dengue but have not been understood their potential against <i>Ae. albopictus</i> larvae, the secondary vector of dengue that also transmits Chikungunya and Zika viruses.

Arboviral vectors dispersal and density in storey buildings: the association of light intensity and air temperature.

Aedes mosquito is the most common arboviral vector in the tropic and subtropic regions that it was dispersed in high-rise buildings up to many storeys. A study reported that similar condition in Indonesia is still limited, although the high-rise buildings are also growing rapidly throughout the country. This study aimed to understand the dispersal and density index of Aedes mosquitoes among storey buildings at the campus of Universitas Muhammadiyah Semarang, Indonesia.

Larvicidal Activity of Ethyl Acetate Extract of Root against the Third-Instar Larvae of Cypermethrin-Resistant Offspring.

Background: extracts have a high larvicidal potential against the laboratory strain of larvae, but the effect on offspring larvae of pyrethroid-resistant strains of the species is lack understood. This study aimed to determine the larvicidal activity of the ethyl acetate extract of tuba root against the third-instar larvae of the Cypermethrin-resistant offspring.

Methods: The experimental study occupied four levels of ethyl acetate extract of namely 10, 25, 50, and 100 ppm, and each level was four times replicated.

Evaluation of Toxicity in Four Extract Types of Tuba Root against Dengue Vector, (Diptera: Culicidae) Larvae.

Background And Objective: Since the Dengue virus spreads rapidly and the vector becomes resistant to insecticides and larvicides, exploration of new compounds that overcome resistance problems, are easily degraded and do not lead to bioaccumulation, is needed. This study evaluated four extract types of Derris elliptica represented the polar, semi-polar and nonpolar extract against the 3rd-instar larvae of Ae. aegypti and determined the effective concentration among the extracts.

Impact of Dengue Surveillance Workers on Community Participation and Satisfaction of Dengue Virus Control Measures in Semarang Municipality, Indonesia: A Policy Breakthrough in Public Health Action.

Objectives: The aim of this study was to assess community participation in Dengue virus control measures, and community satisfaction in the Dengue surveillance workers (DSWs) performance in Semarang municipality after 3 years of empowerment.

Methods: A cross-sectional survey involved 1,018 selected participants from 12 groups of social roles in 141 villages in Semarang municipality, Indonesia. A direct interview was performed using a structured questionnaire to evaluate the acceptance, and satisfaction of the community towards the DSWs.

Effect of D-Allethrin Aerosol and Coil to the Mortality of Mosquitoes.

Background: Commercial insecticides were widely used by communities to control the mosquito population in their houses. D-allethrin is one of insecticide ingredients widely distributed in two different concentrations namely 0.15% of aerosol and 0.

In-vitro study on the larvicidal activity of Manihot glaziovii peel extract against Aedes aegypti larvae.

Use of chemical method to control Aedes aegypti population in the Dengue endemic areas caused the emergence of a resistant strain of this species to insecticide compounds, including temephos. Exploration of the alternative compounds that have larvicidal effects is needed, such as natural products derivate from plants. The current study was designed to evaluate the effective dosage of methanolic extract of Manihot glaziovii peel against the third instar larvae of Aedes aegypti.

Altitudinal distribution of Aedes indices during dry season in the dengue endemic area of Central Java, Indonesia.

Aedes mosquitoes, mainly Aedes aegypti and Aedes albopictus, are the primary and secondary vectors of dengue viruses in Indonesia, with transmission occurring by sucking blood. The density of the vectors is influenced by season and rainfall, but limited by altitude. The aim of the study is to describe the density and distribution of dengue vectors during the dry season based on the altitudes of recent dengue cases in five regencies of Central Java Province, Indonesia.

Distribution of Voltage-Gated Sodium Channel (Nav) Alleles among the Aedes aegypti Populations In Central Java Province and Its Association with Resistance to Pyrethroid Insecticides.

The emergence of insecticide resistant Aedes aegypti mosquitoes has hampered dengue control efforts. WHO susceptibility tests, using several pyrethroid compounds, were conducted on Ae. aegypti larvae that were collected and raised to adulthood from Semarang, Surakarta, Kudus and Jepara in Java.

Molecular surveillance of dengue in Semarang, Indonesia revealed the circulation of an old genotype of dengue virus serotype-1.

Dengue disease is currently a major health problem in Indonesia and affects all provinces in the country, including Semarang Municipality, Central Java province. While dengue is endemic in this region, only limited data on the disease epidemiology is available. To understand the dynamics of dengue in Semarang, we conducted clinical, virological, and demographical surveillance of dengue in Semarang and its surrounding regions in 2012.
