Effectiveness of indoor and outdoor larvitrap modified jars and paralon hit for Aedes spp. Control

Background. Dengue hemorrhagic fever (DHF) is a disease caused by the dengue virus which is transmitted by the mosquito vector Aedes spp. Efforts to control dengue vectors using chemical methods such as the use of larvicides and fogging with insecticides can result in the risk of environmental pollution and also resistance to Aedes spp. Objective. This study aimed to analyze the effectiveness of indoor and outdoor modified larvitrap made from jars and black paralon as well as attractants to control Aedes spp. Methods. This research is applied research in society. Indoor and outdoor larvitrap is made using clear jars and black paralon. The attractants used were Imperata cylindrica soaking water, rice straw, and sugarcane leaves with concentrations of 20 and 30. Indoor and outdoor larvitrap was installed in the respondent’s house in a dengue-endemic area in Pandak village, Banyumas, Indonesia. Observations were carried out on the number of Aedes spp. larvae trapped by larvitrap. Results. The results showed that outdoor larvitraps caught fewer Aedes spp. larvae (46.8) than indoor larvitraps (61.6). The use of attractants between Imperata, rice straw, and sugarcane leaves has a different effect on the number of larvae caught. Most of the Aedes spp. larvae were caught in Imperata soaking water with a concentration of 30 installed in an indoor larvitrap. Conclusion. The use of indoor and outdoor larvitrap modified jars and black paralon at research sites can be effective for controlling Aedes spp. Imperata soaking water with a concentration of 30 proved to be the most effective attractant. © the Author(s), 2023.
