Description of an automatic copulation induction system used to establish a free-mating laboratory colony of Nyssorhynchus deaneorum from Brazil

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND Nyssorhynchus deaneorum is a potential malaria vector because it has been shown to be competent to transmit Plasmodium vivax and Plasmodium falciparum, and because it exhibits antropophilic and endophilic behaviors in some regions of the Amazon. This profile makes Ny. deaneorum a useful mosqui...

The impact of imported malaria by gold miners in Roraima: characterizing the spatial dynamics of autochthonous and imported malaria in an urban region of Boa Vista

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND The number of malaria cases in Roraima nearly tripled from 2016 to 2018. The capital, Boa Vista, considered a low-risk area for malaria transmission, reported an increasing number of autochthonous and imported cases. OBJECTIVES This study describes a spatial analysis on malaria cases in an ...

Do climate changes alter the distribution and transmission of malaria? Evidence assessment and recommendations for future studies

Abstract Malaria, a mosquito-borne infectious disease, is considered a significant global health burden. Climate changes or different weather conditions may impact infectious diseases, specifically those transmitted by insect vectors and contaminated water. Based on the current predictions for climate ch...

Anophelines species and the receptivity and vulnerability to malaria transmission in the Pantanal wetlands, Central Brazil

Mem. Inst. Oswaldo Cruz; 113 (2), 2018
BACKGROUND Studies on malaria vectors in the Pantanal biome, Central Brazil, were conducted more than half a century ago. OBJECTIVES To update anopheline records and assess receptivity and vulnerability to malaria transmission. METHODS Five-day anopheline collections were conducted bimonthly in Salobra...

Ecological characterisation and infection of Anophelines (Diptera: Culicidae) of the Atlantic Forest in the southeast of Brazil over a 10 year period: has the behaviour of the autochthonous malaria vector changed?

Mem. Inst. Oswaldo Cruz; 113 (2), 2018
BACKGROUND In southeastern Brazil, autochthonous cases of malaria can be found near Atlantic Forest fragments. Because the transmission cycle has not been completely clarified, the behaviour of the possible vectors in those regions must be observed. A study concerning the entomological aspects and natura...

Objetivo. Describir algunos aspectos de la bionomía de las especies del género Anopheles presentes ...

First record of anopheles konderi Galvão & Damasceno (Diptera: Culicidae) carrying eggs of dermatobia hominis (Linnaeus Jr. ) (Diptera: oestridae), from oriximiná municipality, Pará, Brazil

Abstract INTRODUCTION: The muscoid fly Dermatobia hominis causes cutaneous myiases in mammals. Females of this species use a vector to carry their eggs to the host. This note describes Anopheles konderi acting as phoretic vector for D. hominis. METHODS: A female A. konderi carrying D. hominis was col...

Factores que inciden en la caracterización de criaderos de Anopheles albimanus Wiedemann (Diptera : Culicidae) en Panamá

Dada la situación actual de los programas de erradicación de la malaria en las Américas, se ha requerido entre otros reorientar el manejo de los vectores de esta enfermedad, profundizando en el conocimiento de los diferentes estados de vida de éstos. En el presente trabajo se describen 38 criaderos p...
