铃木果蝇 (SWD) 对全球软果和核果构成威胁。社会福利署栖息在农场附近的非农作物地区，从那里进入农作物造成损害。需要考虑作物和非作物区域的有效 IPM 控制策略来控制这种经济上重要的害虫。我们进行了一项荟萃分析，以量化果园周围不同非作物栖息地对 SWD 种群的影响，比较作物和非作物栖息地中捕获的 SWD 丰度。总体而言，非农作物生境中的 SWD 丰度高于农作物地区，并且这种差异在邻近林地或含有已知 SWD 寄主植物的田地边缘的农场中最为明显。作物和非作物生境之间的 SWD 丰度差异不受作物类型的影响，但与有机农场相比，在冬季和传统农场中差异最大，表明传统方法可以减少相对 SWD 丰度。铃木果蝇在非作物栖息地越冬，为作物季节以外提供庇护。然而，某些栖息地支持的 SWD 相对丰富度高于其他栖息地，这也受到农场管理的影响。我们讨论这些发现对于有效控制社署意味着什么。
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. 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. 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. 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. 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.
