Genetic modification (use of genetically modified insects)

A method using recombinant DNA technology to create genetically modified insects called the release of insects carrying a dominant lethal (RIDL) is under development by a company called Oxford inInsectechnologies, UK. The method works by introducing a repressible ‘’dominant lethal” gene into the insects. This gene kills the insect but it can be repressed by an external additive (tetracycline), which allows the insects to be reared in manufacturing facilities. This external additive is commonly administered orally and so can be an additive to the insect food. The insects can also be given genetic markers such as DsRED fluorescence, that make monitoring the progress of eradication easier, preferably under field conditions. Biotechnological approaches based on genetically modified organisms (transgenic organisms) are still under development.
