Protocol for genetic engineering in Drosophila suzukii using microinjection

The spotted wing Drosophila (Drosophila suzukii Matsumura) is recognized globally as a significant economic pest. Here, we present a protocol for genetic engineering in D. suzukii using microinjection. We describe steps for genetic engineering techniques, including transposon-mediated germline transformation, recombinase-mediated genome targeting, and CRISPR-mediated gene editing. This protocol can significantly expand the toolkit for functional genomics and genetic control studies of this pest. For complete details on the use and execution of this protocol, please refer to Schetelig and Handler,
