| Summary: | An understanding of the ecological factors and population bionomics of Aedes albopictus can improve control and mitigate the incidence of dengue (DF) and dengue hemorrhagic fever (DHF). The depth knowledge on the biology of dengue vector is crucial to understand various aspect of the disease, including control programme and future outcome. The development performance and survival rate of Ae. albopictus were investigated under four temperatures in response with different types of water and water holding containers which conducted at insectarium UiTM Puncak Alam. Based on the observation, the development performance and survival of the vector mosquito was increased with the increasing of temperature. These findings also showed rain water and coconut shell provide better development rate compared to tap water and plastic cup respectively. The hatching success was 91.7% in rain water and declined to 2% when hatched in tap water. An Ae. albopictusreared in coconut shell showed 50% pupation on day 5 with highest pupation
occurring at the maximum temperature, 35°C. Under four constant temperature ranging from 20°C to 35°C, the highest mortality rate recorded at the maximum temperature. The size of wing reared at the minimum temperature, 20°C was significantly longer than maximum temperature, 35°C. The findings of this study are discussed in the context of changing or increasing water temperature, favourable types of water and preferable water holding containers in vector population and vector competence. Using these key factors control strategies are recommended to manage vector populations as expected increases in temperatures. |
