<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. <b>Materials and Methods:</b> A total of 17 tourist attractions and public places in four districts/cities of Central Java Province were selected as study sites and 25-40 ovitraps were installed in each location for three days. The coordinates, altitude, vegetation density, shade, wind speed, air temperature and humidity were recorded. Ovistrips and water of each ovitrap were observed in the laboratory to determine the ovitrap index (OI) and egg density index (EDI), mosquito species and their susceptibility to temephos. <b>Results:</b> A total of 12,231 eggs were obtained with a range, OI and EDI of 0-1,024, 42% and 31.93 eggs/trap, respectively. Vegetation density, shade and wind speed were significantly associated with the presence of <i>Aedes </i>eggs in the ovitraps (p<0.05), while altitude, temperature and air humidity were correlated with the average of <i>Aedes</i> eggs per ovitrap. <b>Conclusion:</b> Although <i>Aedes</i> larvae in all study sites were susceptible to temephos 0.02 mg/L the results indicated the vulnerability of visitors to <i>Aedes</i>-borne diseases. Further investigation of arbovirus infections in <i>Aedes</i> mosquitoes at tourist attractions and public places is necessary conducted to evaluate the potential and risk of pathogen transmission to visitors. |
