Brazil’s first free-mating laboratory colony of Nyssorhynchus darlingi [PDF]

Revista da Sociedade Brasileira de Medicina Tropical, 2019
INTRODUCTION: The lack of highly-productive Nyssorhynchus darlingi laboratory colonies limits some studies. We report the first well-established laboratory colony of Ny. darlingi in Brazil.

Physical Mapping of the Anopheles (Nyssorhynchus) darlingi Genomic Scaffolds [PDF]

Insects, 2021
Simple Summary Anopheles darlingi mosquitoes are the main vectors of malaria in the Brazilian Amazon. To assign genomic DNA sequences to chromosomes of this species, we performed fluorescence in situ hybridization of DNA probes with salivary glands ...

Asaia (Rhodospirillales: Acetobacteraceae) and Serratia (Enterobacterales: Yersiniaceae) associated with Nyssorhynchus braziliensis and Nyssorhynchus darlingi (Diptera: Culicidae) [PDF]

Revista Brasileira de Entomologia, 2020
Midgut transgenic bacteria can be used to express and deliver anti-parasite molecules in malaria vector mosquitoes to reduce transmission. Hence, it is necessary to know the symbiotic bacteria of the microbiota of the midgut to identify those that can be used to interfering in the vector competence of a target mosquito population.

Susceptibility of Field-Collected Nyssorhynchus darlingi to Plasmodium spp. in Western Amazonian Brazil [PDF]

Genes, 2021
Mosquito susceptibility to Plasmodium spp. infection is of paramount importance for malaria occurrence and sustainable transmission. Therefore, understanding the genetic features underlying the mechanisms of susceptibility traits is pivotal to assessing ...

Nyssorhynchus darlingi genome-wide studies related to microgeographic dispersion and blood-seeking behavior

Parasites & Vectors, 2022
In Brazil, malaria is concentrated in the Amazon Basin, where more than 99% of the annual cases are reported. The main goal of this study was to investigate the population structure and genetic association of the biting behavior of Nyssorhynchus (also ...

Higher risk of malaria transmission outdoors than indoors by Nyssorhynchus darlingi in riverine communities in the Peruvian Amazon

Parasites & Vectors, 2019
Background Malaria remains an important public health problem in Peru where incidence has been increasing since 2011. Of over 55,000 cases reported in 2017, Plasmodium vivax was the predominant species (76%), with P.

Genetic diversity of Nyssorhynchus (Anopheles) darlingi related to biting behavior in western Amazon

Parasites & Vectors, 2019
Background In the Amazon Basin, Nyssorhynchus (Anopheles) darlingi is the most aggressive and effective malaria vector. In endemic areas, behavioral aspects of anopheline vectors such as host preference, biting time and resting location post blood meal ...

Host feeding patterns of Nyssorhynchus darlingi (Diptera: Culicidae) in the Brazilian Amazon.

Acta Tropica, 2020
Nyssorhynchus darlingi (Root) is the dominant malaria vector in the Brazilian Amazon River basin, with additional Anophelinae Grassi species involved in local and regional transmission.

Malaria vectors in the Brazilian Amazon: Anopheles of the subgenus Nyssorhynchus Anopheles do subgênero Nyssorhynchus, vetores da malária na Amazônia brasileira [PDF]

Revista do Instituto de Medicina Tropical de São Paulo, 2000
Various species of Anopheles (Nyssorhynchus) were studied in the Amazon with the objective of determining their importance as malaria vectors. Of the 33 known Anopheles species occurring in the Amazon, only 9 were found to be infected with Plasmodium ...

Inhibition of the complement system by saliva of Anopheles (Nyssorhynchus) aquasalis. [PDF]

Insect Biochemistry and Molecular Biology, 2018
Anopheline mosquitoes are vectors of malaria parasites. Their saliva contains anti-hemostatic and immune-modulator molecules that favor blood feeding and parasite transmission. In this study, we describe the inhibition of the alternative pathway of the complement system (AP) by Anopheles aquasalis salivary gland extracts (SGE). According to our results,
