IN THE MIDST of its intense fogging programme health authorities are also fighting off claims that mosquitoes have become resistant to a chemical in the fog used to destroy them.
A senior health source yesterday flatly denied that its arsenal in the war against the deadly aedes aegypti mosquito was weakened because the insect had grown resistant to the component malathion in the fumigation.
“That is not true. I heard people saying that but they are just talking without any proof,” said an expert in the area who preferred not to be identified.
He revealed that the Ministry of Health was in the process of sending mosquito eggs to Trinidad for testing to determine the effect of malathion on them but that was part of the routine checks and balances. The last time such tests were carried out was three years ago. (AC/LK)
