  • Establishment of Aedes (Ochlerotatus) scapularis (Diptera: Culicidae) in Mainland Florida, With Notes on the Ochlerotatus Group in the United States.
    Journal of medical entomology, 2020
    Co-Authors: Lawrence E. Reeves, Johana Medina, Evaristo Miqueli, Kristin E. Sloyer, William Petrie, Chalmers Vasquez, Nathan D. Burkett-cadena
    Abstract:

    Aedes scapularis (Rondani), a widespread neotropical vector mosquito species, has been included in the mosquito fauna of Florida on the basis of just three larval specimens that were collected in the middle Florida Keys in 1945. Here, we report numerous recent collections of immature and adult Ae. scapularis from multiple locations in two counties of southern Florida. These specimens represent the first records of Ae. scapularis from mainland Florida and the first records of the species in the state since the initial detection of the species 75 yr ago. Collections of both larvae and adults across several years indicate that Ae. scapularis is now established in Broward and Miami-Dade Counties. These contemporary records of this species in Florida may represent novel dispersal and subsequent establishment events from populations outside the United States or a recent reemergence of undetected endemic populations. To confirm morphological identification of Ae. scapularis specimens from Florida, the DNA barcoding region of the cytochrome c oxidase subunit I gene (COI) was sequenced and compared to all other Ochlerotatus Group species from the United States, specifically Aedes condolescens Dyar and Knab (Diptera: Culicidae), Aedes infirmatus Dyar and Knab (Diptera: Culicidae), Aedes thelcter Dyar (Diptera: Culicidae), Aedes tortilis (Theobald) (Diptera: Culicidae), and Aedes trivittatus (Coquillett) (Diptera: Culicidae). Molecular assays and sequencing confirm morphological identification of Ae. scapularis specimens. Maximum likelihood phylogenetic analysis of COI and ITS2 sequences place Florida Ae. scapularis in a distinct clade, but was unable to produce distinct clades for Florida specimens of Ae. condolescens and Ae. tortilis.

  • Mosquitoes (Diptera: Culicidae) and mosquito-borne diseases in Mali, West Africa
    Parasites and Vectors, 2018
    Co-Authors: Fatalmoudou Tandina, Ogobara Doumbo, Alpha Yaro, Sékou Traoré, Philippe Parola, Vincent Robert
    Abstract:

    Mosquito-borne diseases cause major human diseases in almost every part of the world. In West Africa, and notably in Mali, vector control measures help reduce the impact of mosquito-borne diseases, although malaria remains a threat to both morbidity and mortality. The most recent overview article on mosquitoes in Mali was published in 1961, with a total of 88 species. Our present review focuses on mosquitoes of medical importance among which the Anopheles vectors of Plasmodium and filaria, as well as the Culex and Aedes vectors of arboviruses. It aims to provide a concise update of the literature on Culicidae, covering the ecological areas in which the species are found but also the transmitted pathogens and recent innovative tools for vector surveys. This review highlights the recent introduction of invasive mosquito species, including Aedes albopictus and Culex neavei. The comprehensive list of mosquito species currently recorded includes 106 species (28 species of the Anophelinae and 78 species of the Culicinae). There are probable gaps in our knowledge concerning mosquitoes of the subfamily Culicinae and northern half of Mali because most studies have been carried out on the genus Anopheles and have taken place in the southern part of the country. It is hoped that this review may be useful to decision makers responsible for vector control strategies and to researchers for future surveys on mosquitoes, particularly the vectors of emerging arboviruses.

  • Investigation of biota associated and natural infection by sporulated bacteria in Culicidae larvae from São Paulo state, Brazil.
    Journal of invertebrate pathology, 2011
    Co-Authors: Carlos José Pereira Da Cunha De Araujo-coutinho, Thaissa Consoni Bernardino, Eder Soares Pires, Lygia V.s. Esch, Andréa De Barros Pinto Viviani, Clara F.g. Cavados
    Abstract:

    The aim of this study was to investigate the naturally occurring bacteria from Culicidae larvae found in Sao Paulo state between 2006 and 2008 from the Tiete Ecological Park in the municipality of Caraguatatuba. Bacterial strains were obtained after surface sterilization of larvae followed by thermal treatment and incubation in bacteriological media under laboratory conditions. Identification was determined using cytomorphology, biochemical and physiological tests. Strains were characterized by qualitative evaluation of biological activity against Culicidae larvae, comparing protein profiles obtained by electrophoresis of crystal protoxins, electrophoresis of Lysinibacillus sphaericus isoenzymes, detection of the L(2) fraction of Hemolytic BL enterotoxin and amplification of DNA using Multiplex-PCR to detect HBL, NHE, CytK, BceT and EntFM enterotoxins. The results obtained in this study demonstrated that the endosymbiotic bacterial diversity belonging to Bacillus and related genera associated with Culicidae larvae is limited to a number of species that does not vary throughout the seasons.

  • Species composition and fauna distribution of mosquitoes (Diptera: Culicidae) and its importance for vector-borne diseases in a rural area of Central Western - Mato Grosso, Brazil
    EntomoBrasilis, 2017

    Abstract:

    Abstract . This study describes ecological data obtained in a rural area in the State of Mato Grosso, including the insects belonging to the family Culicidae, especially those framed as potential vectors of tropical diseases. In 2015, we collected adult mosquitoes in fragments of forest in a rural area located in Mato Grosso Central West of Brazil. We captured 18,256 mosquitoes of the sub-families Culicinae and Anophelinae and have identified 34 species belonging to 12 genera: Aedes (1 species), Anopheles (8 species), Coquillettidia (1 species), Haemagogus (1 species), Culex (5 species), Psorophora (5 species), Ochlerotatus (4 species), Deinocerites (1 species),  Mansonia (4 species), Sabethes (2 species), Limatus (1 species), Wyeomyia (1 species). The family Culicidae presented high richness and abundance, established by diversity indexes (Margalef α =3.26; Shannon H' = 2.09; Simpson D = 0.19) with dominance of the species Anopheles ( Nyssorhyncus ) darlingi Root (89.8%). This species has considerable epidemiological value, considered the main vector of malaria in Mato Grosso. Many species of mosquitoes are vectors of pathogens that cause disease in humans and domestic animals, transmitting pathogens including viruses (arboviruses), filaria worms (helminths) and protozoa.

Este estudo descreve dados ecologicos de uma area rural do Estado de Mato Grosso e dos insetos da familia Culicidae especialmente aqueles enquadrados como vetores potenciais de doencas tropicais. Em 2015, coletamos mosquitos adultos em fragmentos de floresta em localidades de areas rurais no Mato Grosso regiao Centro Oeste do Brasil. Foram capturados 18.256 exemplares alados de mosquitos das subfamilias Culicinae e Anophelinae e identificadas 34 especies pertencentes a 12 generos: Aedes (1 especie), Anopheles (8 especies), Coquillettidia (1 especie), Haemagogus (1 especie), Culex (5 especies), Psorophora (5 especies), Ochlerotatus (4 especies), Deinocerites (1 especie), Mansonia (4 especies), Sabethes (2 especies), Limatus (1 especie), Wyeomyia (1 especie). A familia Culicidae apresentou alta riqueza e abundância, estabelecida por indices de diversidade (Margalef α = 3.26, Shannon H' = 2.09, Simpson D = 0.19) com predominância da especie Anopheles ( Nyssorhyncus ) darlingi Root (89.8%). Esta especie tem consideravel valor epidemiologico, sendo considerada o principal vetor de malaria em Mato Grosso. Muitas especies de mosquitos sao vetores de patogenos que causam doencas em humanos e animais domesticos, transmitindo patogenos incluindo virus (arboviroses), filarias (helmintos) e protozoarios.
