Abstract

Introduction: Dengue Fever (DF) is a disease spread by Aedes spp. caused by dengue virus infection. The study aimed to identify the density of Aedes spp eggs and larvas stages and the characteristics of their habitat in dengue-endemic areas in Ternate City in September-December 2021. Methods: the research was conducted in four dengue-endemic villages in Ternate City, namely Sangaji, Maliaro, Bastiong Karance, and Bastiong Talangame village. In 80 households, egg density was determined by placing 2 ovitraps in each house, one inside and one outside the house. After a week, the filter paper which is a medium mosquito to lay their eggs in the ovitrap was collected, and the ovitrap index value was calculated. The value of the House Index (HI), Container Index (CI), and Breuteu Index (BI) was used to calculate the larval density. The type and materials of the containers were used to assess the parameters of the larval environment. Results: The ovitrap index value in the four villages was categorized as moderate level 3 (27.50% -36.25%). The highest larval density was found in Sangaji Village (HI = 81%), while the lowest was in Bastion Talangame Village (HI = 70%). The highest CI and BI values were found in Bastiong Karance Village (CI=51.5% and BI=190%), and the lowest was in Maliaro Village (CI=37.5% and BI=128%). Density figures in all endemic villages have a high larval density with a value of 8. Conclusion: There was no significant difference (p>0.05) between the types and the materials of containers in each village in Dengue endemic areas. The high density of the egg and larval stage and the information characteristic of habitat Aedes spp. could be considered as basic information for dengue vector control in Ternate City.
