Drosophila suzukii Matsumura (Diptera: Drosophilidae) is a cosmopolitan polyphagous pest on unripe soft-skinned fruits. We sought to determine (1) temperature treatments that could be used to kill immature D. suzukii in fruit or packaging and (2) whether development on different fruits led to differences in cold tolerance of immature D. suzukii. We reared animals from egg on a banana-based laboratory diet and diets made of apple (Malus domestica Borkhausen; Rosaceae), blueberry (Vaccinium Linnaeus; Ericaceae), cherry (Prunus avium Linnaeus; Rosaceae), grape (Vitis Linnaeus; Vitaceae), orange (Citrus × sinensis (Linnaeus) Osbeck; Rutaceae), raspberry (Rubus Linnaeus; Rosaceae), or strawberry (Fragaria × ananassa Duchesne; Rosaceae) homogenate in agar and measured development time, adult body size, and cold tolerance. Diet type had complex effects on development time; in particular, D. suzukii reared on apple-based or blueberry-based diets developed more slowly to a smaller adult body size than those on other diets. Cold exposure killed eggs and both first and second instars. Survival of 24 hours at +4 °C by feeding third instars was lowest in blueberry and cherry. Five days at +0.6 °C killed all feeding third instars; this treatment is likely sufficient for targeting D. suzukii in fruit. Two hours at −5 °C or −6 °C killed all wandering third instars and pupae; this exposure could be sufficient for sanitation of packaging.

铃木果蝇松村（Drosophila suzukii Matsumura）（双翅目：Drosophilidae）是一种未成熟的软皮水果上的世界性多食性害虫。我们试图确定（1）可用于杀死水果或包装中未成熟铃木的温度处理，以及（2）不同水果的发育是否导致未成熟铃木的耐寒性差异。我们以香蕉为基础的实验室饮食从鸡蛋中饲养动物，饮食包括苹果（Marus domestica Borkhausen;蔷薇科），蓝莓（Vaccinium Linnaeus; Ericaceae），樱桃（Prunus avium Linnaeus; Rosaceae），葡萄（Vitis Linnaeus; Vitaceae），橙色（柑橘×中华（Linnaeus）奥斯贝克；Rutaceae），覆盆子（Rubus Linnaeus; Rosaceae）或草莓（Fragaria × ananassa Duchesne; Rosaceae）在琼脂中匀浆并测量发育时间，成年个体大小和耐寒性。饮食类型对发育时间有复杂的影响。特别是，以苹果或蓝莓为基础的饮食中饲养的铃木D.比其他饮食中的成年人体重更慢。寒冷暴露会杀死卵以及第一和第二龄。喂食第三龄幼虫，在+4°C下的24小时存活率最低的是蓝莓和樱桃。在+0.6°C的温度下放置5天，杀死了所有进食的第三龄幼虫；这种治疗可能足以靶向铃木在水果上。在−5°C或−6°C下的两个小时杀死了所有游荡的第三龄幼虫和p。这种暴露可能足以包装卫生。
