The Consumers’ Association of Penang and Sahabat Alam Malaysia call upon the National Biosafety Board to revoke the approval given to the Institute for Medical Research in October 2010 to release genetically modified male aedes aegypti mosquitoes for the purpose of a field experiment. The applicant and implementer of the field trial is the IMR which had developed the GM mosquitoes in a joint research with UK-based biotech company Oxitec Ltd.
