Article Synopsis
  • Metagenomic research revealed that mosquito viromes are more diverse than just pathogenic viruses that affect humans, highlighting the complexity of mosquito-borne viruses.* -
  • In a study conducted on 866 female mosquitoes in São Paulo Zoo, a new virus was identified through RNA extraction and next-generation sequencing, showing potential as a new species of iflavirus.* -
  • These findings enhance our understanding of viral diversity in mosquitoes and provide a valuable genomic reference, aiding future research in virology and metagenomics.*

The genus Haemagogus (Diptera: Culicidae) includes species that are important vectors of pathogens such as the yellow fever virus. The accurate identification of these species is essential for the control of zoonoses. Females of Hg.

The risk to human health from mosquito-borne viruses such as dengue, chikungunya and yellow fever is increasing due to increased human expansion, deforestation and climate change. To anticipate and predict the spread and transmission of mosquito-borne viruses, a better understanding of the transmission cycle in mosquito populations is needed. We present a pathogen-agnostic combined sequencing protocol for identifying vectors, viral pathogens and their hosts or reservoirs using portable Oxford Nanopore sequencing.

The identification of mosquito species is necessary for determining the entomological components of disease transmission. However, identification can be difficult in species that are morphologically similar. The cytochrome oxidase subunit I () DNA barcode region is considered a valuable and reliable diagnostic tool for mosquito species recognition, including those that belong to species complexes.
