Novel molecular evidence of population structure in Anopheles (Kerteszia) bellator from Brazilian Atlantic Forest

Mem. Inst. Oswaldo Cruz; 114 (), 2019
Anopheles bellator is a primary malaria vector in the Atlantic Forest. Partial sequences of timeless and Clock genes were used to assess the genetic differentiation of five Brazilian populations, which showed strong population structure (e.g. high F ST values and fixed differences) in all pairwise compa...

Pathogen-insect interaction candidate molecules for transmission-blocking control strategies of vector borne diseases

Salud pública Méx; 60 (1), 2018
Abstract: Objective: To analyze the current knowledge of pathogen-insect interactions amenable for the design of molecular-based control strategies of vector-borne diseases. Materials and methods: We examined malaria, dengue, and Chagas disease pathogens and insect molecules that participate in inter...

Ecdysis-related pleiotropic neuropeptides expression during Anopheles albimanus development

Salud pública Méx; 60 (1), 2018
Abstract: Objective: To analyze the transcription pattern of neuropeptides in the ontogeny of a malaria vector, the mosquito Anopheles albimanus. Materials and methods: The transcription pattern of Crustacean CardioActive peptide (CCAP), corazonin, Ecdysis Triggering Hormone (ETH), allatostatin-A, or...

The impact of insecticides management linked with resistance expression in Anopheles spp. populations

Abstract The resistance of some species of Anopheles to chemical insecticides is spreading quickly throughout the world and has hindered the actions of prevention and control of malaria. The main mechanism responsible for resistance in these insects appears to be the target site known as knock-down resis...

Variabilidade genética em populações de Anopheles darlingi (Diptera: Culicidae) e relação ao comportamento da atividade de picar, analisada por RAPD

Acta amaz; 40 (3), 2010
Duas populações naturais de Anopheles darlingi foram analisadas quanto aos padrões de variabilidade genética relacionados ao comportamento hematofágico, cujas coletas foram realizadas no intra, peri e extradomicíio, em dois municípios do Estado do Amazonas: Coari e Manaus. Os resultados evidenciar...
