Background and Aim: Determination of the age of vector mosquitoes is of particular importance in epidemiological studies of diseases transmitted by them, such as viral and parasitic diseases. The objective of this study was to determine the daily age of Anopheles stephensi based on changes in pteridine concentration in female mosquito cuticles by liquid chromatography (HPLC). Methods and Materi...
Since a knowledge of the susceptibility of any species of Anopheles to infection with malaria parasites is of great importance in determining its part in the transmission of malaria, the experiments reported here were undertaken, and included the three most prevalent species of this genus occurring in the United States. As a result of these experiments Anopheles punctipennis is shown to be an e...
Four populations of Anopheles sacharovi Favre occurring in different ecological subregions at altitudes between 353-1,126 m in the Sanliurfa Province of southeast Turkey were compared using morphometric and allozyme analyses. Four allozyme loci were assessed for genetic differentiation among samples from four localities. The similarity phenogram obtained from the allozyme data showed that popul...
During a longitudinal study on vector biology and malaria transmission in western Venezuela the degree of attraction of mosquitoes to 4 people who carried out landing catches was evaluated. An analysis of variance of the log(x + 1)-transformed data showed that there were no significant differences in attractiveness of various individuals to Anopheles nuneztovari, Anopheles marajoara, or Anophel...
Anopheles (Anopheles) mediopunctatus (Lutz) and Anopheles (Anopheles) costai Fonseca & Ramos are redescribed with illustrations of the male genitalia and larval and pupal stages. The pupa of An. costai has paired lateral projections on the wing case, a feature also known in members of the Umbrosus Group from Southeast Asia. An. costai is resurrected from the synonymy of An. mediopunctatus based...
A study of species diversity of Anopheles mosquitoes, biting patterns, and seasonal abundance of important mosquito vectors was conducted in two villages of Chang Island, Trat Province, in eastern Thailand, one located along the coast and the other in the low hills of the central interior of the island. Of 5,399 captured female anophelines, 70.25% belong to the subgenus Cellia and remaining spe...
Malaria is a vector-borne disease that is a great burden on the poorest and most marginalized communities of the tropical and subtropical world. Approximately 41 species of Anopheline mosquitoes can effectively spread species of Plasmodium parasites that cause human malaria. Proposing a natural classification for the subfamily Anophelinae has been a continuous effort, addressed using both morph...
Anopheles darlingi Root is the major vector of human malaria in the Neotropics and has been considered to be the sole malaria vector in French Guiana. The presence of other potential vectors suggests that malaria may be transmitted by other species under certain conditions. From 2006-2011, all anopheline specimens collected from 11 localities were assayed to determine if the Plasmodium circumsp...
The overall focus of this chapter is the impact of phylogeographic studies on information pertinent to vector control, and an update on the relative importance and taxonomic status of five malaria vectors, some of which are species complexes, in the subgenus Nyssorhynchus: Anopheles albimanus Wiedmann, Albitarsis Complex, Anopheles aquasalis Curry, Anopheles darlingi Root, and Anopheles nunezto...
Zika virus is a newly emergent mosquito-borne flavivirus that has caused recent large outbreaks in the new world, leading to dramatic increases in serious disease pathology including Guillain-Barre syndrome, newborn microcephaly, and infant brain damage. Although Aedes mosquitoes are thought to be the primary mosquito species driving infection, the virus has been isolated from dozens of mosquit...
