No. of bitstreams: 1 2021 - Amanda Queiroz Bastos.pdf: 3012328 bytes, checksum: 27c9491acf7f0d897512ab857cdbd4f1 (MD5) Previous issue date: 2021-10-29 CAPES - Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior The mosquitoes, family Culicidae, have 3,588 species classified in two subfamilies: Anophelinae and Culicinae. Both have species of epidemiological importance. The fauna inventory of mosquitoes in areas of natural environment is condiderably important in ecological studies. The natural populations of animals in a given biogeographic area distributed in communities subject to constant fluctuations in response to the environment. During the processes of anthropic action or in the possible periods of recovery of the vegetation cover, knowledge of the biodiversity of mosquito communities in na Atlantic Forest environment is of relevant importance. Since this knowledge is useful to evaluate possible changes in behavior and adaptations in the pattern of activities of mosquitoes considered to be, until then, of wild habit, preferably. The sampling resulted from collections made in two fragments of Atlantic Forest in the state of Rio de Janeiro in municipality of Nova Igua?u in the Associa??o de Taifeiros da Armada (ATA) and in Boa Esperan?a site. The duration of collections in both locations was one year. The present study aimed to assess the richness, diversity, equitability and preference of immatures and adults in both fragments and the influence of climatic factors (temperature, relative humidity and rainfall) on the abundance of mosquitoes. In the two study areas, biweekly visits, sytematic and standardized sampling were performed using a manual sucker to collect the larvae. In ATA, the natural breeding sites surveyed were bamboo stalks, while in the Boa Esperan?a site, ovitraps were randomly distributed and the natural bamboo and bromeliad breeding sites were monitored. Adult spcimens were captured using CDC light traps with CO2 attractiveness, part of the specimens from the collected eggs were used to perform the analysis of possible natural infection by flavivirus (Zika, yellow fever). During the sampling period in the ATA, 3170 larvae were collected in perforated bamboo in eight stems of Five plants, of which 688 specimens reached the adult stage, distributed in 10 genera and 16 species. The richness of the immatures collected in the ATA was 16 species, with a recorded diversity of 1.10 and Shannon?s equitability of 0.57. In the sample area of the Boa Esperan?a site, 5514 larvae were collected and 1322 reached the adult stage: 949 in the plastic container, 80 in the bromeliad and 293 in the bamboo. Of the 5818 eggs collected, 3941 hatched, and 3807 reached the pupal stage and 2370 reached the adult stage. The species from the eggs with the greatest abundance were Aedes albopictus with 61% and Haemagogus leucocelaenus 34%. In the CDC light trap with CO2 attractiveness, 2621 specimens of mosquitoes of these genera were: Culex (84,9%), Wyeomyia (5,3%), Aedes (3,5%) and Limatus (3,1%). A total of 1,229 specimens of mosquitoes: Ae. albopictus (651), Hg. leucocelaenus (565) and Hg. janthinomys (13) from eggs collected at the Boa Esperan?a site were submitted to RT-PCR to detect Flavivirus. The bamboo breeding area showed the greatest diversity and fairness, however, the plastic container had the lowest indexes. Regarding the richness of the immatures found, it was showed greater richness in the bamboo. The adults captured at sample point 5 of the Boa Esperan?a site had the highest levels of diversity, equatability and richness. Evidence was found through the polymerase chain reaction (RT-PCR), partial sequences of Zika v?rus in sample of Hg. leucocelaenus, an important species from the epidemiological point of view in the transmission of the yellow fever v?rus. Os mosquitos, fam?lia Culicidae, possuem 3588 esp?cies v?lidas divididas em duas subfam?lias: Anophelinae e Culicinae. Ambas possuem esp?cies de import?ncia epidemiol?gica. O invent?rio faun?stico de mosquitos em ?reas de ambiente natural ? de consider?vel import?ncia em estudos ecol?gicos. As popula??es naturais de animais em uma determinada ?rea biogeogr?fica distribuem-se em comunidades sujeitas a constantes flutua??es em resposta ao ambiente. Durante os processos de a??o antr?pica, seja nos poss?veis per?odos de recupera??o da cobertura vegetal, o conhecimento da biodiversidade das comunidades de mosquitos em ambiente de Mata Atl?ntica ? de relevante import?ncia. Sendo que, esse conhecimento ? ?til para avaliar as poss?veis mudan?as de comportamentos e adapta??es no padr?o de atividades dos mosquitos considerados, at? ent?o, como de h?bito preferencialmente silvestre. As amostragens foram provenientes de coletas realizadas em dois fragmentos de Mata Atl?ntica do estado do Rio de Janeiro no munic?pio de Nova Igua?u na Associa??o de Taifeiros da Armada (ATA) e no s?tio Boa Esperan?a, a dura??o das coletas em ambos locais foi de um ano. O presente estudo teve como prop?sito avaliar a riqueza, diversidade, equitabilidade e prefer?ncia dos imaturos e dos adultos em ambos fragmentos e a influ?ncia dos fatores clim?ticos (temperatura, umidade relativa do ar e pluviosidade) na abund?ncia dos mosquitos. Nas duas ?reas de estudos foram realizadas visitas mensais e quinzenais, amostragens sistem?ticas e padronizadas utilizando sugador manual para coleta das larvas. Na ATA os criadouros naturais pesquisados foram os colmos de bambu, j? no s?tio Boa Esperan?a foram distribu?das aleatoriamente armadilhas de ovitrampas e monitorados os criadouros naturais bambu e bromeli?ceas, sendo os esp?cimes adultos foram capturados com aux?lio de armadilha luminosa de CDC com atrativo de CO2. Parte dos esp?cimes provenientes dos ovos coletados foram utilizados para realizar a an?lise de poss?vel infec??o natural por Flavivirus (Zika e Febre Amarela). Durante o per?odo de amostragem na ATA foram coletadas 3170 larvas em bambu perfurado em oito colmos de cinco plantas, desse total 688 esp?cimes chegaram ao est?gio adulto, distribu?dos em 10 g?neros e 16 esp?cies. A riqueza dos imaturos coletados na ATA foi de 16 esp?cies, sendo que a diversidade registrada foi de 1,10 e a equitabilidade de Shannon de 0,57. Na ?rea amostral do s?tio Boa Esperan?a foram coletadas 5514 larvas e 1322 chegaram ao est?gio adulto sendo: 949 no recipiente pl?stico, 80 na brom?lia e 293 no bambu. Dos 5818 ovos coletados 3941 eclodiram, e 3807 chegaram ? fase de pupa e 2370 chegaram ? fase adulta. As esp?cies provenientes dos ovos com maior abund?ncia foram Aedes albopictus com 61% e Haemagogus leucocelaenus com 34%. Na armadilha luminosa de CDC com atrativo de CO2, foram capturados 2621 esp?cimes de mosquitos destes os g?neros com a maior abund?ncia foram: Culex (84,9%), Wyeomyia (5,3%), Aedes (3,5%) e Limatus (3,1%). Um total de 1229 esp?cimes de mosquitos: Ae. albopictus (651), Hg. leucocelaenus (565) e Hg. janthinomys (13) provenientes de ovos coletados no s?tio Boa Esperan?a foram submetidos ao RT-PCR para detec??o de Flavivirus. O criadouro bambu apresentou a maior diversidade e equitabilidade, enquanto o recipiente pl?stico apresentou os menores ?ndices. No entanto, imaturos encontrados no recipiente pl?stico apresentaram maior riqueza e no bambu a menor. Os adultos capturados no ponto amostral 5 do s?tio Boa Esperan?a apresentaram os maiores ?ndices de diversidade, equitabilidade e riqueza. Foram encontradas evid?ncias por meio da rea??o em cadeia da polimerase (RT-PCR) sequ?ncias parciais de v?rus Zika em amostras de Hg. leucocelaenus, esp?cie importante no ponto de vista epidemiol?gico na transmiss?o do v?rus amar?lico.

Bed bugs are hematophagous insects which due to their morphological and biological characteristics are able to easily adapt themselves to human households. The authors describe two cases of dermatitis caused by bed bug bites in the city of Rio de Janeiro, Brazil. Patients presented linear lesions in the usual "breakfast, lunch and dinner" arrangement, suggesting this diagnosis. A visit to their dwellings showed infestation of insects identified as Cimex hemipterus. The knowledge of these insects by the dermatological community will contribute to an accurate diagnosis as well as subsidize the dissemination of information aiming for prevention.
