PETALING JAYA: The Health Ministry is using new strategies to combat Aedes mosquitoes that have developed resistance to “traditional” measures. 

Health Ministry director-general Datuk Dr Ismail Merican said among the methods is the use of the Bacillus thuringiensis var. israelensis (Bti) biopesticide to kill mosquito larvae. 

”The mosquitoes have developed some resistance to traditional measures like fogging,” he said when contacted yesterday. 

Bti comes in various forms and the easiest to use are the pellets. Bti is not a contact insecticide and does not harm mammals, bird or fish.  

Dr Ismail said there has been a change in the behaviour of the mosquitoes. 

“Last time, there were specific hours that they were more attracted to people. But from the Singapore experience, there is now a different pattern.“
