Abstract

Genetic manipulation of insects and other arthropods may enable better control strategies to be developed against agricultural pests and disease vectors. Transposon-based transformation techniques have been implemented in Drosophila1 and other insects2 such as medflies3,4 and mosquitoes5,6. A major obstacle in the use of these transposons, however, has been the difficulty in obtaining marker genes that will allow easy and reliable identification of transgenic animals. Here we describe a marker system that is suitable for following gene transfer in most arthropods and in many other phyla.
