Mosquitoes interact with a wide range of viruses including both arboviruses and insect-specific viruses. This study aimed to characterize the RNA viruses that are interacting with Mansonia wilsoni and Coquillettidia hermanoi mosquito species. The total RNA extracted from mosquito pools were sequenced on a Ion torrent platform. Viral contigs were identified against viral databases and their evolutionary relationship were reconstructed. We identified a total of 107 viral sequences, 11 of which were assigned as endogenous viral elements, and at least six known viral families were identified. Phylogenetic reconstructions were performed for 4 viral families. All Mansoniini viruses investigated through phylogenetic analysis are closely related to insect-specific viruses found in other mosquito species although with considerable divergence at the amino acid level, suggesting that we have detected new viral lineages. This study enhanced our understanding about the virome of two sylvatic Mansoniini mosquitoes.

Feeding on the nutrients from fruits and flowers is vital for mosquitoes and increases their lifespan, reproduction, and flight activity. Olfaction is a key sensory modality in mediating mosquito responses to nutrient sources. Previous studies have demonstrated that fruits and flowers can vary in attractiveness to mosquitoes, with some sources preferred over others.

Understanding why Diptera, such as mosquitoes and sand flies, feed on humans is crucial in defining them as vectors of diseases such as malaria, dengue fever, Zika virus, and leishmaniasis. Determining their attraction to humans (anthropophily) helps in assessing the risk of disease transmission, designing effective vector control strategies, and monitoring the effectiveness of existing control measures. An important question is whether they are specifically attracted to humans in preference to other mammals or whether there is something else at play.

Arthropod-borne viruses (arboviruses) pose a major threat to global public health, impacting both human and animal health. Genomic characterization is important for arboviruses because it allows for an understanding of their evolution and improves timely outbreak and epidemic response. In this study, we used high-throughput sequencing and computational analyses to characterize the genomes and evolution of 46 previously unsequenced or partially sequenced arbovirus isolates collected across 23 countries between 1954 and 1984.

Introduction: Climate variability and non-environmental factors such as travel and migration pose an increasing risk of vector-borne infectious diseases to extratropical regions. The European Centre for Disease Prevention and Control has reported autochthonous transmissions of dengue or West Nile virus in Italy, France, Spain, and Germany. Raising awareness and implementing protective measures against mosquitoes will therefore become increasingly relevant in Germany in the future.
