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 ...

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. Mosquito blood-feeding behavior is an essential component to define the mosquito-human contact rate and shape the transmission cycle of vector-borne diseases.

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,

Natural Infection of Nyssorhynchus darlingi and Nyssorhynchus benarrochi B with Plasmodium during the Dry Season in the Understudied Low-Transmission Setting of Datem del Marañon Province, Amazonian Peru. [PDF]

Am J Trop Med Hyg, 2023
. The persistence of malaria hotspots in Datem del Marañon Province, Peru, prompted vector control units at the Ministry of Health, Loreto Department, to collaborate with the Amazonian International Center of Excellence for Malaria Research to identify ...

Mutations Linked to Insecticide Resistance Not Detected in the Ace-1 or VGSC Genes in Nyssorhynchus darlingi from Multiple Localities in Amazonian Brazil and Peru. [PDF]

Genes (Basel), 2023
Indoor residual spray (IRS), mainly employing pyrethroid insecticides, is the most common intervention for preventing malaria transmission in many regions of Latin America; the use of long-lasting insecticidal nets (LLINs) has been more limited ...
