“…Biting tends to begin at dusk, peaking early in the night, and tailing off as the night progresses [111,112] (Table 6). The time of the biting peak and bias towards endo-or exophagy depends on the location, for example in Maranhão, Brazil, Xavier & Rebelo [111] observed a tendency to bite at dusk, indoors.

The dominant Anopheles vectors of human malaria in the Americas: occurrence data, distribution maps and bionomic précis

BackgroundAn increasing knowledge of the global risk of malaria shows that the nations of the Americas have the lowest levels of Plasmodium falciparum and P. vivax endemicity worldwide, sustained, in part, by substantive integrated vector control. To help maintain and better target these efforts, knowledge of the contemporary distribution of each of the dominant vector species (DVS) of human malaria is needed, alongside a comprehensive understanding of the ecology and behaviour of each species.ResultsA database of contemporary occurrence data for 41 of the DVS of human malaria was compiled from intensive searches of the formal and informal literature. The results for the nine DVS of the Americas are described in detail here. Nearly 6000 occurrence records were gathered from 25 countries in the region and were complemented by a synthesis of published expert opinion range maps, refined further by a technical advisory group of medical entomologists. A suite of environmental and climate variables of suspected relevance to anopheline ecology were also compiled from open access sources. These three sets of data were then combined to produce predictive species range maps using the Boosted Regression Tree method. The predicted geographic extent for each of the following species (or species complex*) are provided: Anopheles (Nyssorhynchus) albimanus Wiedemann, 1820, An. (Nys.) albitarsis*, An. (Nys.) aquasalis Curry, 1932, An. (Nys.) darlingi Root, 1926, An. (Anopheles) freeborni Aitken, 1939, An. (Nys.) marajoara Galvão & Damasceno, 1942, An. (Nys.) nuneztovari*, An. (Ano.) pseudopunctipennis* and An. (Ano.) quadrimaculatus Say, 1824. A bionomics review summarising ecology and behaviour relevant to the control of each of these species was also compiled.ConclusionsThe distribution maps and bionomics review should both be considered as a starting point in an ongoing process of (i) describing the distributions of these DVS (since the opportunistic sample of occurrence data assembled can be substantially improved) and (ii) documenting their contemporary bionomics (since intervention and control pressures can act to modify behavioural traits). This is the first in a series of three articles describing the distribution of the 41 global DVS worldwide. The remaining two publications will describe those vectors found in (i) Africa, Europe and the Middle East and (ii) in Asia. All geographic distribution maps are being made available in the public domain according to the open access principles of the Malaria Atlas Project.

“…Foram registrados recentemente em Belém do Pará, nos estudos de Silva 8 . Anopheles evansae é uma espécie de ampla distribuição neotropical; entretanto, em algumas áreas tem sido encontrada em alta densidade, podendo desempenhar papel vetorial secundário 9 . Nos estudos de Rachou 10 , o qual registrou 23 espécies de anofelinos em Santa Catarina não consta a espécie Anopheles evansae.…”

RESUMO ABSTRACT Introduction:The Amazon region of Brazil is endemic for malaria. In the State of Santa Catarina, malaria was eliminated in the 1980s. Since then, a few sporadic isolated autochthonous cases have occurred. However, because malaria vectors are present within Brazilian territory and extensive endemic areas exist in this country, along with the great mobility of people in tourist areas of Santa Catarina, there is the likelihood of reintroduction of the disease. Methods: The following data were used: the database of the Entomology Group of the National Health Foundation, Santa Catarina (ACCES, 1997(ACCES, -2000; the epidemiological surveillance information system of the Health Surveillance Department (Malaria/SC); and the notifiable disease information system (SINAN/SC). These data were transferred to and analyzed in the Microsoft Office Excel 2007 software. Results: Collections were carried out in 48 municipalities and 159 localities, and 12,310 culicids, 11,546 anophelines (93.7%) and 764 others (6.2%) were identified. Three subgenera and 13 species of anophelines were identified.Conclusions: Given that in the municipalities investigated, important vectors such as Anopheles cruzii and Anopheles albitasis were found to be present, with movements of infected individuals from endemic areas, these areas can be considered to be receptive and vulnerable to malaria. These species are suspected of being responsible for malaria transmission in this region, especially in the municipalities of Gaspar, Indaial and Rodeio.

“…Zimmerman (1992) reported that the seasonal increase in anophelines is regulated by the abundance of breeding sites being it directly related to the rainfall. Several studies reported the same phenomenon, with highest densities of anophelines being observed during the rainy season (Marquetti et al, 1992;Xavier & Rebêlo, 1999;Moreno et al, 2002, Barros & Honório, 2007.…”

“…Several studies have shown that climatic factors affect the population dynamics of anopheline mosquitoes (Póvoa et al, 2001;Silva-Vasconcelos et al, 2002;Marquetti et al, 1992;Xavier & Rebêlo, 1999;Moreno et al, 2002). The Roraima State presents two climatic seasons: rainy period (May to September) and dry period (October to April) (Chaves & Rodrigues, 2000).…”
