INTRODUCTION Bioecological aspects of anophelines (Diptera: Culicidae) near areas under the direct influence of the hydroelectric plant reservoir of Serra da Mesa in Goiás, Brazil, were analyzed. METHODS Samples were collected at the surrounding dam area during the phases before and after reservoir impoundment. The influence of climatic and environmental factors on the occurrence of Anopheles...

Quantitative reverse transcription PCR (qRT-PCR) has been an integral part of characterizing the immunity of Anopheles mosquitoes towards Plasmodium invasion. Two anti-Plasmodium factors of Anopheles, thioester-containing protein 1 (TEP1) and nitric oxide synthase (NOS), play a role in the refractoriness of Anopheles towards Plasmodium infection and are generally expressed during infection. How...

The current study included the collection and classification of mosquitoes identification some species because their medical veterinary importance in terms harmful effect on health transmission diseases. Three were diagnosed different sites, namely Anopheles, Culex Aedes, where five types Anopheles four recorded. As for third genus, two it recorded, proportions collected from sites varied among...

To evaluate whether environmental heterogeneity contributes to the genetic heterogeneity in Anopheles triannulatus, larval habitat characteristics across the Brazilian states of Roraima and Pará and genetic sequences were examined. A comparison with Anopheles goeldii was utilised to determine whether high genetic diversity was unique to An. triannulatus. Student t test and analysis of variance ...

Despite their importance as malaria vectors, little is known of the bionomic of Anopheles nili and Anopheles moucheti. Larval collections from 24 sites situated along the dense hydrographic network of south Cameroon were examined to assess key ecological factors associated with these mosquitoes distribution in river networks. Morphological identification of the III and IV instar larvae by the u...

A survey of adult mosquitoes in the area Palmar dam, Uruguay, was conducted from October 1980 to March 1981, prior filling reservoir. The Culicidae fauna consisted 22 species 7 genera: Aedeomyia Theobald, Aedes Meigen, Anopheles Culex Linnaeus, Mansonia Blanchard, Psorophora Robineau-Desvoidy and Uranotaenia Lynch-Arribálzaga; most diverse genera being (subgenus Ochlerotatus Lynch-Arribálzaga),...

background: malaria is the most important vector-borne disease in many tropical countries all over the world. because of the widespread use of pyrethroid insecticide treated mosquito nets in the world, the effects of excito-repellency (er) phenomenon of pyrethroids against main malaria vector, anopheles stephensi were studied. methods: the er phenomenon of three concentrations of two synthetic ...

The recent discovery of a previously unknown genetic subgroup of Anopheles gambiae sensu lato underscores our incomplete understanding of complexities of vector population demographics in Anopheles. This subgroup, named GOUNDRY, does not rest indoors as adults and is highly susceptible to Plasmodium infection in the laboratory. Initial description of GOUNDRY suggested it differed from other kno...
