Mosquitoes are the most important vectors of emerging infectious diseases. During the past decade, our understanding of the diversity of viruses they carry has greatly expanded. Most of these viruses are considered mosquito-specific, but there is increasing evidence that these viruses may affect the vector competence of mosquitoes.

Article Synopsis
  • Haiti faces a significant malaria issue, primarily caused by Plasmodium falciparum, with Anopheles albimanus mosquitoes as the main carriers.
  • Between 2009 and 2018, a total of 232,479 malaria cases were reported, showing a peak in 2010 followed by a sharp decline due to interventions, from 60,130 cases in 2010 to 8,978 by 2018.
  • The study underscores the need for improved data collection and epidemiological monitoring to better understand malaria's impact in Haiti, which affects both urban and rural areas.

Identifying the species of the subfamily Anophelinae that are vectors is important to vector and malaria control. Despite the increase in cases, vector mosquitoes remain poorly known in Brazilian indigenous communities. This study explores Anophelinae mosquito diversity in the following areas: (1) a Yanomami reserve in the northwestern Amazon Brazil biome and (2) the Pantanal biome in southwestern Brazil.

Background: Aedes albopictus is a very invasive mosquito, which has recently colonized tropical and temperate regions worldwide. Of concern is its role in the spread of emerging or re-emerging mosquito-borne diseases. Ae.

Article Synopsis
  • Mosquito oviposition behaviors vary across species, with a focus on the unique egg-laying process of Sabethes albiprivus observed through high-speed video.
  • Researchers used a sapucaia nut trap to mimic the natural tree hole habitat of Sa. albiprivus, allowing for detailed observation of its egg-laying technique.
  • Females perform rapid up-and-down flights before catapulting eggs at nearly 1 m/s by curling their abdomen, demonstrating a complex and efficient egg-laying mechanism.
