Brazilian mosquito (Diptera: Culicidae) fauna: I. Anopheles species from Porto Velho, Rondônia state, western Amazon, Brazil

Abstract

This study contributes to knowledge of Anopheles species, including vectors of Plasmodium from the western Brazilian Amazon in Porto Velho, Rondônia State. The sampling area has undergone substantial environmental changes as a consequence of agricultural and hydroelectric projects, which have caused intensive deforestation and favored habitats for some mosquito species. The purpose of this study was to diagnose the occurrence of anopheline species from collections in three locations along an electric-power transmission line. Each locality was sampled three times from 2010 to 2011. The principal adult mosquitoes captured in Shannon trap were Anopheles darlingi, An. triannulatus, An. nuneztovari l.s., An.gilesi and An. costai. In addition, larvae were collected in ground breeding sites for Anopheles braziliensis, An. triannulatus, An. darlingi, An. deaneorum, An. marajoara, An. peryassui, An. nuneztovari l.s. and An. oswaldoi-konderi. Anopheles darlingi was the most common mosquito in the region. We discuss Culicidae systematics, fauna distribution, and aspects of malaria in altered habitats of the western Amazon.

Plasmodium vivax Landscape in Brazil: Scenario and Challenges

“…In the area of the Santo Antonio Dam, near the city of Porto Velho in the southwestern Amazon region, An. darlingi was the main vector between 2010 and 2011, with a density peak occurring simultaneously with increasing dam water levels 19,20. Migration of workers and families into the area combined with increasing mosquito density led to an upsurge on malaria incidence, mainly caused by P. vivax 19,21.…”

“…darlingi was the main vector between 2010 and 2011, with a density peak occurring simultaneously with increasing dam water levels 19,20. Migration of workers and families into the area combined with increasing mosquito density led to an upsurge on malaria incidence, mainly caused by P. vivax 19,21. Discontinued incentives to building fish farms in some areas had the adverse effect, as many of these ended up abandoned leading to perennial mosquito breeding sites altering the seasonality of malaria as demonstrated in the municipality of Cruzeiro do Sul 22.…”

Comparative Vector Bionomics and Morphometrics of Two Genetically Distinct Field Populations of Anopheles darlingi Root from Belize, Central America and Zungarococha, Peru, South America

“…In Brazil, An. darlingi larvae have been collected in small and large temporary ponds in an area where a hydroelectric dam was under construction (124) and from irregular excavation pits associated with manual brick manufacturing (40) and gold extraction (63). Even in these temporary manmade habitats, An.…”

Monitoring ofPlasmodiuminfection in humans and potential vectors of malaria in a newly emerged focus in southern Iran

“…Mosquitoes control is an important method in the global malaria control program and has been considered to be the most effective measure for eradication and reduction of malaria transmission at the public level in different parts of the world [8]. World climatic changes associated with human activity, which affect development and survival rate of the malaria vectors may change anopheline species composition [9]. Thus, a full understanding of environmental aspects can be a main factor in malaria control strategies.…”
