Molecular and entomological surveillance of malaria vectors in urban and rural communities of Benguela Province, Angola.

Background: Malaria is a major public health problem in Angola, with Anopheles gambiae sensu lato (s.l.) and An.

The V410L knockdown resistance mutation occurs in island and continental populations of Aedes aegypti in West and Central Africa.

The extensive use of insecticides for vector control has led to the development of insecticide resistance in Aedes aegypti populations on a global scale, which has significantly compromised control actions. Insecticide resistance, and its underlying mechanisms, has been investigated in several countries, mostly in South American and Asian countries. In Africa, however, studies reporting insecticide resistance are rare and data on resistance mechanisms, notably knockdown resistance (kdr) mutations, is scarce.

Insect-specific flaviviruses and densoviruses, suggested to have been transmitted vertically, found in mosquitoes collected in Angola: Genome detection and phylogenetic characterization of viral sequences.

This report describes a survey of RNA and DNA viruses carried out in adult mosquitoes from Angola, raised under laboratory conditions from field-collected immature forms. This viral genomic survey was performed using different sets of primers targeting groups of arboviruses with a considerable impact on human health, including flaviviruses, alphaviruses, and phleboviruses. Furthermore, the viral survey that was performed also included detection of densoviruses.

Population structure of a vector of human diseases: in its ancestral range, Africa.

, the major vector of dengue, yellow fever, chikungunya, and Zika viruses, remains of great medical and public health concern. There is little doubt that the ancestral home of the species is Africa. This mosquito invaded the New World 400-500 years ago and later, Asia.
