The Asian tiger mosquito Aedes albopictus is a major public health concern because of its invasive success and its ability to transmit pathogens. Given the low availability of treatments against mosquito-borne diseases, vector control remains the most suitable strategy. The methods used thus far are becoming less effective, but recent strategies have emerged from the study of mosquito-associated microorganisms. Although the role of the microbiota in insect biology does not require further proof, much remains to be deciphered in mosquitoes, especially the contribution of the microbiota to host nutrient metabolism. Mosquitoes feed on plant nectar, composed of mostly fructose. We used stable isotope probing to identify bacteria and fungi assimilating fructose within the gut of Ae. albopictus. Mosquitoes were fed a 13 C-labelled fructose solution for 24 h. Differences in the active microbial community according to the sex of mosquitoes were highlighted. The bacterium Lelliottia and the fungi Cladosporium and Aspergillus dominated the active microbiota in males, whereas the bacterium Ampullimonas and the yeast Cyberlindnera were the most active in females. This study is the first to investigate trophic interactions between Ae. albopictus and its microbiota, thus underscoring the importance of the microbial component in nectar feeding in mosquitoes.

谁在白纹伊蚊肠道菌群内吃果糖？

由于其侵入性成功和传播病原体的能力，亚洲虎蚊白纹伊蚊是主要的公共卫生问题。鉴于针对蚊媒疾病的治疗手段很少，病媒控制仍然是最合适的策略。迄今为止，所使用的方法已变得不太有效，但是从与蚊子相关的微生物的研究中出现了新的策略。尽管微生物群在昆虫生物学中的作用不需要进一步的证明，但在蚊子中仍有许多尚待破译，尤其是微生物群对宿主营养代谢的贡献。蚊子以植物花蜜为食，主要由果糖组成。我们使用了稳定的同位素探测技术来鉴定Ae肠道内的果糖同化细菌和真菌。白化病。给蚊子喂食13 C标记的果糖溶液24小时。根据蚊子的性别，活跃的微生物群落的差异被强调。男性中活跃的微生物群是细菌中的Lelliottia和真菌Cladosporium和Aspergillus，而女性中，Ampullimonas细菌和Cyber​​berdnera酵母则是最活跃的。这项研究是第一个研究Ae之间的营养相互作用的研究。白化病及其微生物群，因此强调了微生物成分在蚊子的花蜜摄食中的重要性。相反，Ampullimonas细菌和Cyber​​lindnera酵母在女性中最活跃。这项研究是第一个研究Ae之间的营养相互作用的研究。白化病及其微生物群，因此强调了微生物成分在蚊子的花蜜摄食中的重要性。相反，Ampullimonas细菌和Cyber​​lindnera酵母在女性中最活跃。这项研究是第一个研究Ae之间的营养相互作用的研究。白化病及其微生物群，因此强调了微生物成分在蚊子的花蜜摄食中的重要性。
