Abstract

Background: Aedes aegypti is associated with dengue, Zika, and chikungunya transmission. These arboviruses are responsible for national outbreaks with severe public health implications. Vector control is one of the tools used to prevent mosquito proliferation, and SumiLarv® 2MR is an alternative commercial product based on pyriproxyfen for larval/pupal control. In this study, the residual effectiveness of SumiLarv® 2MR in different regions of Brazil was evaluated in simulated field conditions. Methods: We conducted a multicenter study across four Brazilian states—Amapá, Pernambuco, Rio de Janeiro, and São Paulo—given the importance to the country's climatic variances in the north, northeast, and southeast regions and their influence on product efficiency. The populations of Ae. aegypti from each location were held in an insectary. Third-instar larvae (L3) were added every 2 weeks to water containers with SumiLarv® 2MR discs in 250-, 500- and 1000-l containers in Amapá and Rio de Janeiro, and 100-l containers in Pernambuco and São Paulo, using concentrations of 0.04, 0.08, and 0.16 mg/l. Results: Adult emergence inhibition over 420 days was observed in all tests conducted at a concentration of 0.16 mg/l; inhibition for 308–420 days was observed for 0.08 mg/l, and 224–420 days for 0.04 mg/l. Conclusions: Sumilarv® 2MR residual activity demonstrated in this study suggests that this new pyriproxyfen formulation is a promising alternative for Aedes control, regardless of climatic variations and ideal concentration, since the SumiLarv® 2MR showed adult emergence inhibition of over 80% and residual activity greater than 6 months, a period longer than that recommended by the Ministry of Health of Brazil between product re-application in larval breeding sites.

Abstract

Chagas disease (CD) is a neglected tropical disease of high morbidity and mortality. Despite the great reduction in the incidence of acute chagas disease (DCA) cases, the occurrence of these cases may be related to oral transmission by the ingestion of contaminated food, especially in the Amazon region, which over the last few years has been gaining prominence. Through tabulation of data contained in SINAN - Notifiable Diseases Information System - by socio-demographic profile, transmission mode and notifications made in the period from 2016 to 2021. The aim of this research was to trace a profile of disease behavior in the state of Amapá and thus guide control activities. The analysis showed that all age groups and races can be affected by the disease and that surveillance and control actions should be intensified mainly for the oral form of transmission, aiming at a decrease in the occurrence in the coming years, since it is a disease that affects hundreds of people in the state over the years. La enfermedad de Chagas (EC) es una enfermedad tropical desatendida de alta morbilidad y mortalidad. A pesar de la gran reducción en la incidencia de casos de enfermedad de chagas aguda (ADD), la ocurrencia de estos casos puede estar relacionada con la transmisión oral por la ingestión de alimentos contaminados, especialmente en la región amazónica, que en los últimos años ha ido ganando protagonismo. A través de la tabulación de los datos contenidos en el SINAN - Sistema de Información de Enfermedades de Notificación Obligatoria - por perfil sociodemográfico, modo de transmisión y notificaciones realizadas en el período de 2016 a 2021. El objetivo de esta investigación fue trazar un perfil del comportamiento de la enfermedad en el estado de Amapá y así orientar las actividades de control. El análisis mostró que todos los grupos de edad y razas pueden verse afectados por la enfermedad y que las acciones de vigilancia y control deben intensificarse principalmente para la forma oral de transmisión, con el fin de disminuir la ocurrencia en los próximos años, ya que es una enfermedad que afecta a cientos de personas en el estado a lo largo de los años. A doença de Chagas (DC) é uma doença tropical negligenciada, de alta morbimortalidade. Apesar da grande redução na incidência dos casos de Doença de Chagas Aguda (DCA), a ocorrência destes casos pode estar relacionada à transmissão oral pela ingestão de alimentos contaminados, principalmente na região amazônica, que ao longo dos últimos anos vem ganhando destaque. Através de tabulação de dados contidos no SINAN – Sistema de Informação de Agravos de Notificação – por perfil sócio-demográfico, modo de transmissão e notificações realizadas no período de 2016 a 2021. O objetivo da pesquisa foi traçar um perfil de comportamento da doença no estado do Amapá e assim nortear as atividades de controle. A análise demonstrou que todas as faixas etárias e raças podem ser acometidas pela doença e que as ações de vigilância e controle devem ser intensificadas principalmente para a forma oral de transmissão, visando decréscimo da ocorrência nos próximos anos, visto que é uma doença que acomete centenas de pessoas no estado ao longo dos anos.

Abstract

We report the first record of Aedes albopictus (Diptera: Culicidae) in the state of Amapá, northern Brazil. Two female specimens were collected from a Shannon trap in the locality of Ilha de Santana, municipality of Santana, Amapá. The occurrence of the species was confirmed with the installation of ten ovitraps. Aedes albopictus is a species of epidemiological importance for the transmission of arboviruses. Amapá was one of two Brazilian states without any record of this species. RESUMO Relatamos o primeiro registro de Aedes albopictus (Diptera: Culicidae) no Estado do Amapá, no norte do Brasil.

Abstract

Projeto PIATAM Mar A malária no município de Macapá é principalmente peri urbana, áreas estas caracterizadas por ressaca, pela presença de fragmentos de floresta e assentamentos desordenados (invasões). O objetivo deste estudo foi verificar a importância dos Anopheles darlingi e Anopheles marajoara na transmissão de malária em Macapá. O estudo foi realizado de outubro de 2007 a setembro de 2008, na comunidade de Lagoa dos Índios, Macapá. Foram coletados 4.601 mosquitos, dos quais 3.029 foram Anopheles marajoara (65,8%), 917 Anopheles darlingi (19,9%), 429 Anopheles braziliensis (9,3%), 208 Anopheles triannulatus (4,5%), 18 Anopheles peryassui (0,4%) e cinco Anopheles nuneztovari (0,1%). Apenas 32,8% dos espécimes foram coletadas no intradomicilio (1.511) e 67,2% no peridomicilio (3.090). O Indice de Picada Homem Hora do An. darlingi no intradomicilio variou entre 0 a 6,5 e no peridomicilio de 0 a 22 picadas homem hora. Já para o An. marajoara a variaçao foi de 0 a 22 no intradomicilio e de 0 a 175,5 no peridomicilio. A analise das exúvias e da dissecção de genitália resultaram na confirmaçao das duas espécies estudadas, An. darlingi e An. marajoara, e que o An. marajoara é a única espécie do complexo albitarsis circulante na área. A abundância dos vetores flutuou associada com o padrão sazonal das chuvas. An. darlingi é mais abundante no final e inicio das chuvas, enquanto o An. marajoara esteve presente em alta densidade durante todo o período de chuvas. Dos 4.601 mosquitos testados, 100 foram positivos para plasmódios humanos pelo método de ELISA, resultando em uma taxa de infecção de 2,17%. Dos 3.029 An. marajoara testados 71 (2,34%) foram positivos e dos 917 An. darlingi, 28 (3,05%). Este estudo demonstrou que as duas espécies estudadas mantêm a transmissão de malária durante todo o ano, ratificando assim a importância das mesmas. Malaria in the municipality of Macapá is mainly peri urban, which are characterized by flooding area, presence of forest fragments and disorganized settlements. The aim of this study was to determine the importance of Anopheles darlingi e Anopheles marajoara in the malaria transmission in Macapá. The study was carried out from October 2007 to September 2008, in the Lagoa dos Índios community, Macapá. It was collected 4,601 mosquitoes, from which 3,029 were Anopheles marajoara (65,8%), 917 Anopheles darlingi (19,9%), 429 Anopheles braziliensis (9,3%), 208 Anopheles triannulatus (4,5%), 18 Anopheles peryassui (0,4%) and 5 Anopheles nuneztovari (0,1%). Only 32.8% (1.511) of the adult mosquitoes were collected indoors and 67.2% (3.090) outdoors. The index of the bites by man and by hour for An. darlingi in the intradomicile had ranged from 0 to 6.5 and in the peridomicile from 0 a 22. As for the An. marajoara the range was from 0 to 22 in the intradomicile and from 0 to 175.5 in the peridomicile. The analysis of the exuvia and the genitalia dissecation had resulted in the confirmation of the two species, An. darlingi and An. marajoara, and that the An. marajoara is the only albitarsis complex specie that is circulating in the study area. The vectors abundance had flutuated associated with the sazonal pattern of the rain. An. darlingi is the most frequent at the beginning and end of the rain, while An. marajoara was present, in high density, during the rainy season. From the 4,601 tested mosquitoes, 100 were positive for human malaria parasites by the ELISA method with a infection index of 2.17%. The infection index for An. marajoara was 2,34% (71/3,029) and for An. darlingi 3.05% (28/917). This study had demonstrated that the two studied species are responsible for the malaria transmission maintenance during the whole year, thus confirming the importance of both.

Abstract

Introduction: Use of a Bacillus sphaericus based mosquito larvicide was evaluated as an intervention for malaria vector control at a mining site in Amapá, Brazil. Impacts on larval and adult densities of the primary vector Anopheles darlingi were measured over the course of a 52 week study period., Methods: In Calçoene, State of Amapá, gold mining activity occurs in 19 mining sites in gold-miners of Lourenço. Large pools are formed in mining sites and naturally colonized by Anopheles darlingi. During one year, the impact of applications of VectoLex® CG to these larval sources was evaluated. Applications of 20kg/ha were made as needed, based on 10 immature (3rd, 4th instars and pupae) surveillance of health and established thresholds., Results: One hundred percent initial control was observed 48h after each treatment. The pools received from 2-10 (5.3±1.6) treatments during the year. The average re-treatment interval in productive pools was 9.4±4.3 weeks. During weeks 3-52 of the study, mean density of late stage larvae was 78% and pupae were 93% lower in the treated pools than in untreated pools (p< 0.0001, n=51) while reduction of adult mosquitoes was 53% in comparison to the untreated area during the last five months of the study, which were the rainy season (p<0.001)., Conclusions: VectoLex® CG reduced immature Anopheles darlingi infestation levels during the entire study period, and reduced adult mosquito populations during the rainy season.
