“…Immature Limatus durhamii Theobald mosquitoes, a species naturally infected with the Guama virus, can develop in breeding sites ranging from tree holes to landfill percolation tanks [16,17]. Immature forms of Anopheles species have been recorded in artificial habitats [18,19], including An. darlingi Root, which was found in an artificial lagoon in the urban region of Manaus in the state of Amazonas [20].…”

Anthropogenic environments provide favorable conditions for some species, which is especially true of mosquitoes that present eclecticism at the moment of choice for the site of oviposition. In the present study, the diversity of mosquitoes was assessed by providing plastic containers, bamboo internodes, and tires in a forest, the forest edge, and peridomicile environments in a rural settlement area. Eighteen sampling points were chosen, delimited by a buffer of 200 m, placed in three environments: forest, forest edge, and peridomicile. In each environment, larvitraps were installed, separated by a minimum distance of 7 m and 1 m from the ground. A total of 10,131 immature mosquitoes of 20 species were collected. The most abundant species was Culex urichii (29.5%), followed by Trichoprosopon digitatum (27.1%), and Cx. (Melanoconion) spp. (10.4%). There was a difference in the composition of immature mosquito populations between larvitraps (p < 0.0005), and the plastic container hosted a greater diversity of species, whereas tires presented a greater abundance of individuals. The forest, forest edge, and peridomicile environments were also different with regard to diversity of immature mosquito populations (p < 0.0010). The forest edge was the environment with the greatest diversity of species, followed by the peridomicile and forest environments. In the forest and peridomicile, plastic container larvitraps had the greatest diversity, whereas the forest edge tire presented the largest number of individuals. Further, tire larvitraps collected the largest number of individuals in all environments. Ten species associated with the bamboo internode and tire were identified. The preference of species for artificial larvitraps, such as the plastic container and tire, even in wild environments was noted. These artificial objects may represent a risk factor for the population living in this region, as all vector species found in the study were present in plastic containers and tires.

“…A utilização de recipientes artificiais contendo água como locais de deposição de ovos pelas fêmeas grávidas de Culicidae pode corresponder a mero oportunismo ou indicar mudanças de hábitos (Beier e col 6 ., 1983; Luz e col. 24 , 1987). Juntamente com a mudança de hábito por parte do adulto, a sobrevivência e o desenvolvimento das larvas, em criadouros artificiais, pode indicar que esses mosquitos sejam portadores de adaptação genética.…”

INTRODUÇÃO: A utilização pelos Culicidae de recipientes contendo água para a colocação de seus ovos, em área antropogênica, pode indicar plasticidade genética que os direcione evolutivamente no sentido da domiciliação. Nesse sentido, foram coletadas as diferentes espécies de Culicidae que colonizam recipientes alocados em mata ciliar, na área rural. MATERIAL E MÉTODO: Foram instalados recipientes de pneu, plástico, lata e bambu, em mata ciliar, em área rural no Norte do Paraná, Brasil. RESULTADOS: Coletaram-se larvas de Cx. grupo coronator, Cx. declarator, Cx. laticlasper, Cx. (Melanoconion) secção Spissipes, Cx. tatoi, Tr. compressum, Tr. pallidiventer, Ae. terrens, Cx. mollis, Cx. bigoti, Hg. leucocelaenus, Cx. eduardoi, Cx. quinquefasciatus, Li. durhamii e Toxorhynchites sp. As cinco primeiras espécies foram específicas de pneus. As duas espécies de Trichoprosopon ficaram restritas a bambu. Ae. terrens e Cx. mollis foram caletadas em pneu e bambu, Cx. bigoti foi coletada em pneu, lata e bambu, enquanto que Hg. leucocelaenus só não foi encontrada em lata. As quatro últimas espécies foram coletadas em todos os tipos de recipientes. Cx. quinquefasciatus, Cx. eduardoi, Li. durhamii tiveram significante flutuação populacional. CONCLUSÕES: O pneu caracterizou-se como o recipiente mais aceito pelos culicídeos. As áreas onde a mata ciliar esteve mais densa e o locais onde o solo esteve mais úmido foram os pontos com maior número de capturas. A mata ciliar, mesmo muito reduzida e alterada, foi suficiente para abrigar várias espécies de culicídeos. As espécies caputradas podem ser portadoras de plasticidade gênica que as capacitem a colonizar ambientes antropogênicos.

Identification keys to the Anopheles mosquitoes of South America (Diptera: Culicidae). I. Introduction

et al. 2020

Background The worldwide genus Anopheles Meigen, 1918 is the only genus containing species evolved as vectors of human and simian malaria. Morbidity and mortality caused by Plasmodium Marchiafava & Celli, 1885 is tremendous, which has made these parasites and their vectors the objects of intense research aimed at mosquito identification, malaria control and elimination. DNA tools make the identification of Anopheles species both easier and more difficult. Easier in that putative species can nearly always be separated based on DNA data; more difficult in that attaching a scientific name to a species is often problematic because morphological characters are often difficult to interpret or even see; and DNA technology might not be available and affordable. Added to this are the many species that are either not yet recognized or are similar to, or identical with, named species. The first step in solving Anopheles identification problem is to attach a morphology-based formal or informal name to a specimen. These names are hypotheses to be tested with further morphological observations and/or DNA evidence. The overarching objective is to be able to communicate about a given species under study. In South America, morphological identification which is the first step in the above process is often difficult because of lack of taxonomic expertise and/or inadequate identification keys, written for local fauna, containing the most consequential species, or obviously, do not include species described subsequent to key publication. Methods Holotypes and paratypes and other specimens deposited in the Coleção Entomológica de Referência, Faculdade de Saúde Pública (FSP-USP), Museo de Entomología, Universidad del Valle (MUSENUV) and the US National Mosquito Collection, Smithsonian Institution (USNMC) were examined and employed to illustrate the identification keys for female, male and fourth-instar larvae of Anopheles. Results We presented, in four concurrent parts, introduction and three keys to aid the identification of South American Anopheles based on the morphology of the larvae, male genitalia and adult females, with the former two keys fully illustrated. Conclusions Taxonomic information and identification keys for species of the genus Anopheles are updated. The need for further morphology-based studies and description of new species are reinforced.
