The temporal dynamics of protective symbionts have rarely been characterized outside of aphid hosts. Here, we determine the prevalence of Spiroplasma in two populations of Drosophila hydei where Spiroplasma infection had been previously recorded (UK and Japan). We observe that infection in both populations is variable over time and confirm the persistence of Spiroplasma in the UK population for 9 years. Thus, variable prevalence over time appears to be a common feature of these symbioses.
除蚜虫宿主外，保护性共生菌的时间动态很少被描述。在这里，我们确定了海德氏果蝇两个种群中螺旋体的流行情况，此前已记录到这两个种群感染了螺旋体（英国和日本）。我们观察到两个种群中的感染随时间变化，并且证实了英国种群中螺旋体持续存在了9年。因此，随时间变化的流行率似乎是这些共生关系的一个共同特征。
