In Indonesia, common types of mosquito-borne diseases caused by infected mosquitoes are dengue fever, malaria, and chikungunya. Dengue fever seems to be a perennial problem in Indonesia, as its cases have been reported each year. Bandung is one of the cities that has more cases than the average number of dengue cases per city in Indonesia. Prevention of dengue fever by monitoring the number of Aedes aegpty (the main vector of dengue fever) in an area can suppress the number of dengue cases. One of the methods used for monitoring and controlling Aedes aegypti is by using ovitrap (mosquito egg trap). It is simple, inexpensive, and most importantly, it has an impact on lowering the population of Aedes aegypti. Ovitrap works by providing water/liquid as a breeding site for female mosquitoes to lay their eggs. This helps the observer collecting samples of these eggs hence laid. Previous studies have reported that Aedes aegypti has preferences for selecting breeding sites for oviposition, including the characteristics of the water. In this study, water used in ovitrap was replaced with different liquid solutions commonly found at home. Ovitraps with different solutions were tested in Bandung, Indonesia from June – July 2021. Nine different solutions were made from 9 substances; MSG (monosodium glutamate), fertilizer, granulated sugar, honey, palm sugar, salt (NaCl), cat food, fish food, and dog food. All of the substances were dissolved in distilled water and made in 100 ppm (100 mg/L or 100 ml/L) concentration. Distilled water was used as a control. Ovitrap was made from a plastic cup (height: 11 cm, diameter of upper end: 9 cm, diameter of lower end: 5.5 cm) and its outer surface was covered with a black plastic bag. Filter paper was put inside the plastic cup as a substrate for mosquito eggs to stick. Ovitrap was then filled with 300 ml of solution. Ten ovitraps (9 solutions + 1 control) was put inside and outside the house, conducted in three houses, making a total of 60 ovitraps. After 26 days, eggs from all ovitraps were counted and the data tested with T test. The aims of this study were to determine Aedes aegypti’s preferences to oviposit in different solutions and to determine ovitrap’s effectiveness if put inside and outside a house. Solutions that contained protein (dog food, fish food, cat food) significantly were chosen by mosquitoes to oviposit, and the dog food solution was observed to have the highest number of eggs. Ovitrap had better effectiveness if put inside, as the number of eggs observed were more as compared to ovitraps positioned outside. To summarize, indoor water bodies that contain protein have a high risk as breeding sites for Aedes aegypti to spread dengue fever.
