Dengue hemorrhagic fever (DHF) is still a health problem in Indonesia, transmited by Aedes aegypti. One of vector control method against Aedes aegypti larvae has conducted using Bacillus thuringiensis due to safe for the environment. The objectives of this study was to isolate and identify B. thuringiensis which toxic to Ae. aegypti larvae at various habitat and ecosystem in the District Magela…

The study was conducted in (2011) and the soil samples were collected from 20 locations cons & of 5 spots with 50 cm interval. The toxicity of all isolates of Bacillus thuringiensis were t…
Using of Bacillus thuringiensis H-14 as a Biolarvacide are more commonly on this decade. Institute of Vector Control and Reservoir Disease (IVCRD) has used coconut as a medium for B.thuringiensis H-14. This research used only coconut water that was took from many kind of places with difference on altitudes. Locations of this research were from Parangtritis (with altitude < 20 m dpl)), Purwero…

To control dengue haemorrhagic fever (DHF) it is necessary to apply an effective method. Furthermore, it should not contaminate the environment and has a long term effect. A biological agent namely Bacillus thuringiensis israelensis (Bti) which is toxic for Diptera larvae has been used. It is safe for humans and has a long term effect to control the DHF vector Ae. aegypti. Bti is a rod-shaped s…
