The invasive spotted wing drosophila, an insect pest that recently invaded most parts of the world, is a major pest of soft fruits. The application of an environmentally friendly method, such as the sterile insect technique (SIT), is especially important in greenhouses where the biocontrol methods in use are not compatible with the insecticide application. This CRP should focus on the improvement of the sterile insect technique (SIT) package to support field implementation against Drosophila suzukii.The objective is to identify and overcome constraints of implementing SIT with other complementary techniques. The background information required for SIT, such as mass-rearing and radiation biology, has been developed under CRP D43003. However, scale up for implementation needs to be developed to ensure the success of SIT programmes against D. suzukii. This research is expected to further advance the application of the SIT against Drosophila suzukii,The expected outcome would be that the SIT and compatible control methods are being implemented and used by member states as appropriate to reduce crop losses and pesticide residues in food.


The overall objective is to advance development and implementation of SIT for integration with other biocontrol in greenhouses and open field

Specific objectives

To implement SIT for Drosophila suzukii

To develop genetic sexing strains and assess the efficiency of male only releases

Implement biological control agent use in combination with SIT for Drosophila suzukii management

Investigate long distance and cross jurisdiction shipping of sterile D. suzukii
