我们研究了库蚊幼虫如何影响模拟集装箱水生生境中的细菌丰度、组成和多样性。CX的微生物区系。并与其幼虫栖息地进行了比较。CX的存在。枯草杆菌幼虫改变了细菌群落组成，降低了细菌丰富度、多样性和丰富度。对固氮单胞菌、Delftia、假单胞菌、动物群、未归类肠杆菌和类杆菌有抑制作用，而对Prosthecbacter sp.、H.phaga sp.、Clostridium sp.、未归类梭菌科和金杆菌属有抑制作用。在CX存在下增强。斜纹夜蛾幼虫。CX.与其幼虫栖息地相比，Restaans幼虫拥有独特的和较少多样性的细菌群落。这些发现证明了CX。轮虫幼虫在集装箱水生生境微生物群落的结构中起着关键作用，并可能降低这些水生系统的营养质量，改变其分解过程和食物网动态。研究结果还表明，蚊子幼虫对寄生在其体内的幼虫环境中的细菌具有高度的选择性。这些发现为更有针对性的研究提供了新的机会，以确定作为蚊子幼虫食物的特定细菌分类群，以及那些可以用于疾病控制的细菌分类群。
We examined how larvae of Culex restuans mosquito influences the bacterial abundance, composition and diversity in simulated container aquatic habitats. The microbiota of Cx. restuans larvae were also characterized and compared to those of their larval habitats. The presence of Cx. restuans larvae altered the bacterial community composition and reduced the bacterial abundance, diversity and richness. Azohydromonas sp., Delftia sp., Pseudomonas sp., Zooglea sp., unclassified Enterobacteriaceae and unclassified Bacteroidales were suppressed while Prosthecobacter sp., Hydrogenaphaga sp., Clostridium sp., unclassified Clostridiaceae and Chryseobacterium sp. were enhanced in the presence of Cx. restuans larvae. Cx. restuans larvae harbored distinct and less diverse bacterial community compared to their larval habitats. These findings demonstrate that Cx. restuans larvae play a key role in structuring the microbial communities in container aquatic habitats and may lower the nutritional quality and alter the decomposition process and food web dynamics in these aquatic systems. The findings also demonstrate that mosquito larvae are highly selective of the bacterial taxa from the larval environment that colonize their bodies. These findings provide new opportunities for more focused studies to identify the specific bacterial taxa that serve as food for mosquito larvae and those that could be harnessed for disease control.
