“…Even in commercial high‐tunnel systems, netting reduced D. suzukii oviposition and delayed the impact on fruit by up to 3 weeks (Leach et al, 2016). Netting could be deployed as a vertical barrier around the crop margins at the start of the cropping season, limiting entry of low‐flying D. suzukii from the non‐crop habitat while allowing pollinator access over the top (Cini et al, 2012; Groot et al, 2021; Leach et al, 2016). However, without a roof barrier meeting these mesh borders, the effect on D. suzukii populations within the crop and related fruit damage can be limited.…”

“…Recommendations for management of non‐crop habitats surrounding fruit crops warrant more research as these areas support natural enemies important for predation and parasitism of a variety of pests (Holland & Fahrig, 2000; Marshall & Moonen, 2002; Veres et al, 2013) and increases biodiversity on the neighbouring farmlands (Garratt et al, 2017; Groot et al, 2021; Haro‐Barchin et al, 2018; Montgomery et al, 2020).…”

1. Drosophila suzukii (SWD) poses a threat to soft and stone fruit globally. SWD inhabits non-crop areas adjacent to farms from where it moves into crops to cause damage. Effective IPM control strategies, considering both the crop and non-crop area, are needed to control this economically important pest.2. We conducted a meta-analysis to quantify the impacts of different non-crop habitats around fruit farms on SWD populations, comparing abundance of SWD trapped in crop and non-crop habitats.3. Overall, SWD abundance was greater in non-crop habitats than in cropped areas and this difference was greatest in farms adjacent to woodland, or field margins containing known SWD host plants.4. The difference in SWD abundance between crop and non-crop habitats was not affected by crop type but was greatest in the winter months and in conventional compared to organic farms, indicating conventional approaches can reduce relative SWD abundance. 5. Drosophila suzukii overwinter in non-crop habitats which provide refuge outside the cropping season. However, certain habitats support greater relative abundance of SWD than others and this is also affected by farm management. We discuss what these findings mean for effective control of SWD.

“…We found that D. suzukii adults had higher population density, even up to ten times more, in the forest border than inside the vineyard. This observation aligns with findings reported in the literature that D. suzukii prefers the surrounding vegetation (Briem et al, 2018;Groot et al, 2021;Ioriatti et al, 2015;Mazzetto et al, 2020;Santoiemma, Trivellato, Caloi, Mori, & Marini, 2019;Weißinger, Samuel, et al, 2019;Weißinger, Schrieber, et al, 2019). However, during the grape ripening, females tended to migrate into the vineyards.…”

“…In this study, it is possible to observe that although occurring in the same period, the population peaks were different between the observed years. This may be related to the climatic conditions and phenological grape stage, which can change each year, as observed by Groot et al (2021) through monitoring in raspberry orchards in Slovenia. In the second year of our study, we noted a reduction in relative humidity and an increase in temperature during the ripening period compared to the first year.…”

The invasive pest, spotted wing drosophila (Drosophila suzukii (Matsumura, 1931) or SWD), damages various soft-skinned fruits, severely impacting orchards and vineyards economically. Current sorting practices in commercial production may overlook early-stage SWD infestations, as visible signs take a few days to appear. Our study focused on managing SWD infesting fruits (blueberry, cherry, and raspberry) without visible signs using an artificial atmosphere with elevated CO2 and low temperature. We hypothesized that these factors affect SWD survival and possibly interact, with potential variations among different soft- or stone-fruit species or varieties. High CO2 concentrations and cold storage both negatively affected SWD development. A 24-h 100% CO2 fumigation, without cold storage, significantly reduced SWD infestations in all 3 fruit species studied. On the other hand, 10% CO2 without cold storage did not cause a significant infestation reduction in cherries. Cold storage alone was too slow to be considered effective. Concurrent low-temperature treatment and CO2 treatment reduced the insecticidal efficacy of CO2 fumigation. Optimal fruit sanitation was achieved with a 3-h 100% CO2 treatment at ambient temperature before cold storage. Raspberries were the most suitable host for SWD development, with over a 5-fold higher SWD development compared to blueberries and over 50 times more than in cherries. We discussed the observed interactions between CO2 fumigation and chilling and suggested a simple postharvest SWD management protocol using optimal CO2 levels, exposure times, and chilling periods—achievable without complex equipment.
