Abstract Drosophilid species with different life histories have been shown to exhibit similar behavioral patterns related to locating and utilizing resources such as hosts, mates, and food sources. Drosophila suzukii (Matsumura) is an invasive species that differs from other frugivorous drosophilids in that females lay eggs in ripe and ripening fruits instead of overripe or rotten fruits. We hypothesized that there may be diurnal and/or seasonal patterns associated with the movement of drosophilid species into and out of crop fields and their attraction to fermentation-odor-based monitoring traps, and that D. suzukii would conform to similar patterns. To test these hypotheses, we deployed passive, 2-headed Malaise traps between crop fields and wooded edges to simultaneously catch flies moving into and out of crop fields. We also deployed monitoring traps with a fermentation-based bait between crop fields and wooded edges and within crop rows. Traps were deployed weekly in June–August in 2014 and 2015 at two commercial blackberry farm in Cleveland County, NC, and were checked hourly for 24 h, except during darkness. Both D. suzukii and other drosophilid species moved between crop fields and wooded edges and were attracted to monitoring traps primarily during the morning and evening hours. Whereas other drosophilids were captured in traps throughout the season, few D. suzukii were caught in traps until early to mid-July in both years and increased as the season progressed. Understanding D. suzukii movement and activity patterns is essential for the development of effective management strategies.

黑莓农业生态系统中存在的果蝇物种（双翅目：果蝇科）的昼夜和季节性活动模式，重点是斑点翅果蝇

摘要 具有不同生活史的果蝇物种已被证明表现出与定位和利用资源（如宿主、配偶和食物来源）相关的相似行为模式。Drosophila suzukii (Matsumura) 是一种入侵物种，与其他食果果蝇不同，雌性在成熟和成熟的果实中产卵，而不是在过熟或腐烂的果实中产卵。我们假设可能存在与果蝇物种进出农田及其对基于发酵气味的监测陷阱的吸引力相关的昼夜和/或季节性模式，并且 D. suzukii 将符合类似的模式。为了验证这些假设，我们在农田和树木繁茂的边缘之间部署了被动的 2 头 Malaise 陷阱，以同时捕捉进出农田的苍蝇。我们还在农田和树木繁茂的边缘以及作物行内部署了带有发酵诱饵的监测陷阱。2014 年和 2015 年 6 月至 8 月每周在北卡罗来纳州克利夫兰县的两个商业黑莓农场部署陷阱，并在 24 小时内每小时检查一次，黑暗期间除外。D. suzukii 和其他果蝇物种都在农田和树木繁茂的边缘之间移动，并且主要在早晨和晚上被吸引到监测陷阱。尽管其他果蝇在整个季节都被捕获在陷阱中，但很少有 D. suzukii 在这两年的 7 月初至中旬之前被捕获，并且随着季节的进行而增加。了解 D. suzukii 的运动和活动模式对于制定有效的管理策略至关重要。
