Accelerating research on Spotted Wing Drosophila management using genomic technologies

Spotted Wing Drosophila (Drosophila suzukii) is an invasive species and a serious pest of berry and soft-skinned fruit crops. The close genetic relationship between D. suzukii and other well-studied Drosophila species has provided researchers with an already extensive genetic toolkit. The reference genome and transcriptome of this insect have been annotated and made publicly available since 2013, and facilitate basic and applied research. In this review, we present a synthesis of recent research that implements next-generation sequencing and genomic technologies to better understand biological questions concerning this important pest. Much of the work performed is directly applicable to improving agricultural management practices, and includes topics such as insecticide response and resistance, invasion demographics, seasonal biology, and RNA interference technologies for pest control.
