The invasive insect pest Drosophila suzukii causes extensive damage to soft-skinned fruit crops as they ripen. Current control methods involve the application of chemical pesticides, but this approach is ineffective and environmentally hazardous. To investigate the potential of bacterial pathogens carried by D. suzukii as biocontrol agents, we characterized bacteria associated with D. suzukii larvae in two parts of Hesse, Germany, by collecting infested fruits and culturing individual bacteria from moribund specimens for taxonomic classification by 16S rDNA sequencing. Among the bacteria we detected, some had a detrimental effect on the host whereas others were neutral or beneficial. When the detrimental and beneficial bacteria were presented simultaneously, we observed complex tripartite interactions that modulated the insect's innate immune response. Our study provides insight into the complex relationships within the microbiome and pathobiome of D. suzukii and may lead to the isolation of bacteria that can be used as biological control agents.

在德国受灾地区鉴定与入侵性害虫果蝇Suzukii有关的昆虫病原菌。
入侵的害虫铃木果蝇（Drosophila suzukii）在成熟时对软皮果类作物造成广泛损害。当前的控制方法涉及化学农药的应用，但是这种方法无效且对环境有害。为了研究铃木衣原体作为生物防治剂携带的细菌病原体的潜力，我们通过收集被侵染的果实并从垂死的标本中培养单个细菌以通过16S rDNA分类进行分类，从而鉴定了与铃木原虫相关的细菌在德国黑森州的两个地区。排序。在我们检测到的细菌中，有些对宿主有有害作用，而另一些则是中性或有益的。当有害细菌和有益细菌同时出现时，我们观察到复杂的三方相互作用会调节昆虫的 的先天免疫反应。我们的研究提供了对铃木D.微生物群和致病菌群内复杂关系的深入了解，并可能导致分离出可用作生物防治剂的细菌。
