Genetic engineering in insects of agricultural importance.
The past five years have witnessed the extension of genetic transformation techniques into 11 insect species covering four orders within the Insecta. While the robustness of these transformation systems can be improved, there is now a highly likely probability that transformation of a given insect species will ensue, provided transposable element-containing plasmid DNA can be effectively delivered to the embryo or some other life stage. These developments have shifted emphasis to concerns of transgene stability and the regulation of the rearing and release of these transgenic insects. They have also led to some elegant demonstrations of genetic sexing mechanisms in Drosophila melanogaster with the expectation that similar systems be extended into pest insect species. These developments and issues are discussed in this short review.
