Bait spray control

The research has been very successful in strawberry, raspberry and cherry. A coded product containing sugars (now named ‘Probandz’) and a commercially available adjuvant Combi-Protec are both very attractive to  spotted wing drosophila (SWD) adults. When …

Push-pull control strategy

Research carried out by PhD student Christina Conroy as part of the CTP for Fruit Crop Research studentship scheme, identified a chemical repellent that causes a reduction in egg laying in strawberries up to 6 metres away from the sachet containing the …

Recent UK research into SWD led by Niab

Three particularly exciting new control approaches were investigated in Project SF/TF 145a including the reduction of over-wintering populations, the use of a ‘push-pull’ technique and the use of bait sprays for control during the season. All of these …

Reducing overwintering populations

During the monitoring process, data also showed that the traps nearest the crop on the woodland edge captured the most SWD, enabling growers to make better decisions about trap placement. Although numbers of SWD increased in the crop later in the year, a …

Sterile insect technique

Sterile males are produced and introduced regularly by BigSis staff, to the semi-natural areas surrounding crops and within the crops themselves. These sterile males compete with wild males to mate with wild female spotted wing drosophila (SWD), which …

Strawberry and raspberry resistance

In a Growing Kent & Medway funded project, in partnership with Asplins PO and WB Chambers, Niab screened many accessions of strawberry and raspberry to identify if any show tolerance to SWD. Across the life of the project a wide range of strawberry and …
