Abstract


Aedes aegypti and Aedes albopictus are dominant mosquito vectors that transmit life-threatening arboviral diseases like dengue, yellow fever and chikungunya all over the world. Water holding containers produced by humans are main important habitats for the preimaginal development of these mosquitoes. The elimination of their breeding sites is among the ways to control dengue and other arboviral diseases. Thus, this study was conducted to assess the abundance and relative importance of each breeding site of Aedes aegypti and Aedes albopictus in order to minimize or eradicate dengue cases in Dumaguete City. In this study, all water holding containers in nine sampling sites were visually inspected for the presence of mosquito larvae and pupae. Mosquito larvae and pupae were then collected from the containers and identified. The relative importance of the breeding site per species was calculated. Results of this study showed that plastic container had the highest relative importance for Aedes aegypti larvae while drainage canal had the highest relative importance for Aedes albopictus. However, drainage canal showed the highest relative importance for the pupae of both species. This may show that plastic container is more preferred for oviposition by gravid Ae aegypti but drainage canal provides favorable pupal development. Moderately turbid water and high organic content from fallen leaves and other debris in these breeding sites may serve as suitable artificial breeding habitat for Aedes mosquitoes.
