NCKU develops bacillus thuringiensis israelensis to better mosquito control (news)

Tainan, Taiwan, September 17, 2015

The primary preventative measure to reduce dengue infections is the control of mosquito populations. For better and more environmental friendly management of dengue mosquito populations, National Cheng Kung University (NCKU), Tainan, Taiwan, has recently produced 100 kilograms of Bacillus thuringiensis israelensis (Bti) to put into dengue endemic sites on campus.

For the control of dengue vectors, the university is applying Bti to dengue endemic sites, not only around the campus but in the neighborhood to stop the spread of dengue.

Dr. Tzen-Yuh Chiang, a professor of life sciences at NCKU, said, bioinsecticides like Bti is a safer option to be used to kill mosquitoes.

Bti is a naturally occurring soil bacterium that can effectively kill mosquito larvae present in water, according to Chiang.

To deal with the dengue outbreak in Tainan, we are able to culture Bti in our labs with yeast extract in 24 hours, said Chiang.

He also noted that biological approaches are being considered as alternatives to control mosquito populations and bioinsecticides, a combination of biological controls and insecticides, are considered as best mosquito control.
