The Institute for Medical Research has completed one run of its field trial involving genetically-modified male Aedes aegypti mosquitoes at a forest near Bentong, Pahang. IMR director Dr Shahnaz Murad said the institute released about 6,000 GM mosquitoes at the site on Dec 21, along with a similar number of normal male mosquitoes. ”The experiment was successfully concluded on Jan 5,” she said in a press statement here yesterday.
