13. Anopheles gambiae no Brasil: antecedentes para um “alastramento silencioso”, 1930-1932
Resumo O artigo analisa a chegada e identificação do mosquito africano Anopheles gambiae no Brasil em 1930 e as primeiras reações de cientistas e autoridades de saúde pública contra as epidemias de malária causadas por essa espécie. Apesar de ter sido reconhecido como perigoso vetor da malária, sua presença em território nacional foi negligenciada

14. Chicken eggs as a surveillance tool for malaria and leishmaniasis vector presence
Abstract INTRODUCTION: Malaria and leishmaniases are transmitted by vectors during blood-feeding. Vector-infected animals develop antibodies against the vector’s saliva. This study evaluated IgY antibody detection in the chicken eggs exposed to bites from Migonemyia migonei, Lutzomyia longipalpis and Anopheles aquasalis. METHODS: We used ELISA to quant

15. Novel molecular evidence of population structure in Anopheles (Kerteszia) bellator from Brazilian Atlantic Forest
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 comparisons between Bahia sample and the others from Paraná

16. Current vector control challenges in the fight against malaria in Brazil
Abstract In Brazil, malaria is an important public health problem first reported in 1560. Historically, fluctuations in malaria cases in Brazil are attributed to waves of economic development; construction of railroads, highways, and hydroelectric dams; and population displacement and land occupation policies. Vector control measures have been widely used wi

17. A re-annotation of the Anopheles darlingi mobilome
Abstract The mobilome, portion of the genome composed of transposable elements (TEs), of Anopheles darlingi was described together with the genome of this species. Here, this mobilome was revised using similarity and de novo search approaches. A total of 5.6% of the A. darlingi genome is derived of TEs. Class I gypsy and copia were the most abundant superfam

18. O meio ambiente como um sistema complexo: o caso da diminuição da malária na Amazônia Legal (LA)
Resumo: No Brasil, a malária é uma doença endêmica presente principalmente na Amazônia Legal (LA), que representa mais de 99% dos casos do país. Em 2000, o número de novos casos de malária em LA foi de 613,3 mil, diminuindo para 265,4 mil casos em 2011, queda de 56,7%. O sistema de propagação da malária depende de muitas variáveis inter-relaciona

19. Fitness cost in field Anopheles labranchiae populations associated with resistance to the insecticide deltamethrin
Abstract We evaluated in the present study the effect of deltamethrin resistance on the fitness cost of the filed populations of Anopheles labranchiae. A susceptible population was used as reference to do different comparisons. We selected the most resistant larvae population collected from northern Tunisia. Eggs were used for study of life history traits in

20. 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?
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 natural infection of anophelines (Diptera: Culicidae) captur

21. Anophelines species and the receptivity and vulnerability to malaria transmission in the Pantanal wetlands, Central Brazil
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, Mato Grosso do Sul state, for one year. Indoors, mos

22. Redescription of larva, pupa and adult of Anopheles (Anopheles) annulipalpis (Diptera: Culicidae) and the removal of the specie of the Cycloleppteron Series
ABSTRACT The redescription of male, female, pupa and larva of Anopheles (Anopheles) annulipalpis Lynch Arribálzaga, 1878 is presented. The species is included in the Cycloleppteron Series of Anopheles, although several authors consider that this is artificial. The redescription of Anopheles annulipalpis demonstrate that pupae have laticorn trumpet. By this

23. Destaque para o sistema evolutivo de Plasmodium falciparum no sudeste da Mata Atlântica
Resumo A eliminação da malária pode ocorrer no Brasil antes de 2030. Embora seja viável no Brasil e em outras regiões endêmicas do mundo, reconhece-se a importância da resistência de parasitos e vetores às intervenções. A resistência contra drogas e inseticidas pode levar à malária residual. Aqui, descrevemos um novo fenômeno que está ocorren

24. Composição e diversidade de mosquitos (Diptera: Culicidae) em parques urbanos localizados na região Sul do município de São Paulo, Brasil
Resumo Parques urbanos do município de São Paulo contêm remanescentes de Mata Atlântica. No sul da cidade há 30 parques municipais, sendo os parques Santo Dias e Shangrila alvos deste estudo. Este estudo teve a proposta de levantamento da fauna de culicídeos desses dois parques no sul da cidade de São Paulo e avaliar a presença de potenciais bioindic
