Recent developments in transgenic insect technology

In this short review, David O'Brochta and Peter Atkinson examine recent progress in the development of transgenic insect technology. To date, only Drosophila melanogaster and a few closely related species can be routinely transformed; transformation is far from routine in all other insects. The key bottleneck that has impeded progress has been the identification of transposable elements or viruses that are mobile in target species such as the mosquito, Anopheles gambiae. These mobile genetic elements will serve as platforms upon which effective gene vectors, genetagging agents and enhancer traps will be designed and constructed. Significant progress has been made on a number of research fronts.
