Abstract
Temperature is often identified as the main environmental factor affecting the growth of the mosquito population. It is important to study the effect of temperature on the life parameters of Aedes albopictus and Aedes aegypti in the local environment using the local strains. This will subsequently provide an in-depth understanding on the biology of Aedes mosquitoes which will eventually affect the transmission of dengue viruses directly to human. In this study, we examined the effect of constant temperatures (25°C, 27°C, 30°C and 33°C) on the developmental period of local Aedes albopictus and Aedes aegypti strains using environmental chambers. Two categories of the containers (artificial - a glass jar, tire and plastic cup and natural - coconut shell) were used to examine the association of the types of containers to the development of both Aedes albopictus and Aedes aegypti. Based on the developmental data, it was found that the increase in temperature reduced the developmental period of the mosquito except for the first instar larvae. In addition, both strains were found to be able to develop and survive at all selected temperatures up to 33°C. In terms of the types of breeding containers, shortest development was recorded in the coconut shells, followed by tires, glass jars and plastic cups for both Aedes species. These findings provided valuable baseline information on the potential effects of climate change on the bionomics of Aedes albopictus and Aedes aegypti in future projection of Aedes density towards an improve vector control.
