Distribution of black flies (Diptera: Simuliidae) in the State of Espírito Santo, Brazil

Entre os anos de 2004 e 2008 foram realizadas coletas de Simuliidae em várias localidades no Estado do Espírito Santo, Brasil. No total, 66 córregos e rios das doze principais bacias hidrográficas do estado foram amostrados. Dezessete espécies foram coletadas, sendo que nove delas representam ocorrências novas para o estado (Simulium pertinax, S. jujuyense, S. rubrithorax, S. subnigrum, S. travassosi, S. spinibranchium, S. hirtipupa, S. lutzianum e S. anamariae), duplicando o número de espécies conhecidas no estado.We conducted a freshwater survey from 2004 to 2008 in several localities of Espírito Santo, Brazil. In total, 66 streams and rivers were sampled in the 12 hydrographic basins of the state. We collected and identified 17 species of which nine represent new records (Simulium pertinax, S. jujuyense, S. rubrithorax, S. subnigrum, S. travassosi, S. spinibranchium, S. hirtipupa, S. lutzianum e S. anamariae). These findings doubled the number of records of black fly species to the State of Espírito Santo, Brazil

Vascular Flora Of The Legado Das Águas, Reserva Votorantim, Municipalities Of Tapiraí, Miracatú And Juquiá, São Paulo, Brazil

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)We present a list of vascular plants found in Legado das Águas, Reserva Votorantim, a private reserve having an area of approximately 35,000 ha that spans the municipalities of Tapiraí, Miracatú, and Juquiá, in the state of São Paulo, Brazil. The reserve is part of a complex of state-protected areas including Alto Ribeira Touristic State Park, Intervales State Park, Carlos Botelho State Park, Jurupará State Park, and Serra do Mar State Park. Together, these form an important and large area of continuous and well-preserved forest. Our study, which involved two main floristic surveys in March/April 2013 and April 2014, recorded 768 species, representing 131 families and 432 genera. The majority of species were angiosperms (619) representing 106 families and 370 genera. There were also two species of gymnosperms belonging to two genera in separate families; 147 species of ferns and lycophytes belonging to 23 families and 60 genera. In demonstrating the presence of almost 800 species of plants, of which 16 are threatened, our study highlights the importance of floristic surveys and the critical role of private protected areas in managing and preserving native flora. © 2016 Check List and Authors.1262011/22923-8, FAPESP, Fundação de Amparo à Pesquisa do Estado de São Paulo2015/9444-4, FAPESP, Fundação de Amparo à Pesquisa do Estado de São PauloFundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

Infección inducida en el roedor selvático Dasyprocta leporina (Rodentia: Dasyproctidae), con huevos larvados de Lagochilascaris minor (Nematoda: Ascarididae) Induced infection in the wild rodent Dasyprocta leporina (Rodentia: Dasyproctidae) with larval eggs of Lagochilascaris minor (Nematoda: Ascarididae)

Ejemplares de Dasyprocta leporina Linnaeus, 1758 fueron criados alejados de su ambiente natural. A los 3 ó 4 meses de edad, se los inoculó por vía oral con huevos de Lagochilascaris minor Leiper, 1909 obtenidos de una paciente nativa. Los huevos se los incubó por más de 80 dias, para que de ellos fuese posible obtener por compresión mecánica, larvas que se mantuviesen vivas en medio acuoso por 48 horas o más. Sacrificados los animales a los 14 ó 46 dias posteriores a la infección, se hallaron en los músculos esqueléticos larvas ovilladas dentro de nódulos inflamatorios, los cuales no presentaban reacción a cuerpo extraño, abscedación o calcificación. El desarollo de los nódulos no parecía afectar la normalidad de los hospedadores. Las larvas obtenidas eran similares a las descritas por SPRENT como de tercer estadio para estos helmintos. Ratones blancos infectados con material similar, no presentaron nódulos en sus músculos ni se pudo recuperar de sus tejidos larva alguna. Por los hallazgos obtenidos con la infección de estos animales, se postula que el helminto no posee ciclo pulmonar y que su desarrollo requiere de un hospedador intermediario.<br>Specimens of Dasyprocta leporina (Linnaeus, 1758) were raised out their natural environment. At three to four months of age they were orally inoculated with Lagochilascaris minor (Leiper, 1909) eggs obtained from a native patient. The eggs were incubated for more than 80 days so that it was possible to obtain, by mechanical compression, larvae that could be maintained alive in liquid medium for 48 hours or more. The animals were sacrificed 14-46 days after infection and tangled larva in inflammatory nodules were found in skeletal muscle without foreign body reaction, abscess formation or calcification. The development of the nodules did not seem to affect the hosts. The larvae obtained were similar to those described by SPRENT as the third stage of these helminths. When white mice were inoculated with similar material it was not possible to recuperate larva from their tissues nor were nodules found. Based on these results it is postulated that the helminth does not present a pulmonary cycle and that its development requires an intermediary host

Lagoquilascaríase humana: sobre três casos encontrados nos Distrito Federal, Brasil Human lagochilascariasis: about three cases found in the Federal District, Brazil

Três novos casos humanos de infecção por Lagochilascaris minor são apresentados. Todos os pacientes eram oriundos do Estado do Pará, Brasil, e viviam em zona rural ou próximo à mata. As lesões, no momento da consulta, localizavam-se no pescoço, mastóide e ouvido, estando já fistulizadas; em dois casos havia também envolvimento do sistema nervoso central. Amostras de tecidos, retiradas das lesões, revelaram, ao exame histológico, ovos e vermes em vários estádios de sua evolução. A identificação da espécie foi confirmada através do estudo de larvas e adultos eliminados, pelas fístulas cutâneas, de mistura com pus. O tratamento consistiu em excisão cirúrgica das tumorações e administração de antihelmínticos, com bons resultados. Em dois pacientes, no entanto, houve recidiva das lesões, após cura aparente, indicando que as drogas utilizadas não destroem os ovos do parasito.<br>Three new cases of human infection with Lagochilascaris minor are reported. All the patients were from the State of Pará (Brazil), living in rural areas or close to the forest. They were admitted to hospitals in the Federal District due to the presence of abscesses in the region of the neck, ear, mastoid process and, in two of them, to the involvement also of the central nervous system. Microscopic examination of tissue samples taken from the lesions showed sections of eggs and worms - in different evolutive stages - identified as Lagochilascaris minor. Larvae and adult worms obtained from existing fistulae proved also to be of the same species. The three patients were treated with autihelmintic drugs and surgical excision of the lesions, with good clinical results. In two of them, however, relapsing occurred, suggesting that the drugs do not destroy the worm eggs, in spite of the apparent healing of the lesions

Avaliação agroindustrial e parâmetros genético de progênies de cana-de-açúcar em fase inicial na zona canavieira do Litoral Norte de Pernambuco Agroindustrial evaluation and genetic parameters of sugarcane progenies at the initial phase in a sugarcane plantation zone of north coast of Pernambuco

Neste trabalho, objetivou-se avaliar o desempenho agronômico, industrial e a magnitude dos parâmetros genético de progênies de cana-de-açúcar na zona canavieira do Litoral Norte de Pernambuco. Os experimentos foram desenvolvidos durante o ano agrícola 2006/2007 no Litoral Norte de Pernambuco, no município de Igarassu, dentro de área da Usina São José. O delineamento experimental foi de blocos casualizados, com cinco repetições, utilizando-se como tratamentos 24 genótipos (20 provenientes dos cruzamentos e quatro variedades padrões). A parcela constou de três sulcos de 6 m, espaçados de 1,30 m, com 10 plântulas por sulco, (espaçados de 0,6 m dentro do sulco, totalizando 30 plântulas por parcela), perfazendo uma área total de 23,4 m². O corte foi realizado no décimo mês após o transplantio, onde foram avaliadas as seguintes variáveis: tonelada de cana por hectare (TCH), tonelada de pol por hectare (TPH), Fibra (FB), pol % corrigida (PCC), pureza (PZA), Brix (BX) e açúcar total recuperável (ATR). As progênies dos cruzamentos: RB855035 X RB 72454; RB 865230 X RB855035; Tuc71-7 X RB72454 e RB72454 X Tuc71-7, destacaram-se para as variáveis TPH, FB, PZA e BX. Há variabilidade genética entre as progênies dos cruzamentos para todas as variáveis avaliadas. As estimativas de h²m foram expressivas para as variáveis TPH, TCH, PCC, FB, BX e ATR, indicando a possibilidade de êxito na seleção dessas variáveis dentro da região canavieira do Litoral Norte de Pernambuco.<br>The objective of our research was to evaluate the agronomical, industrial performance and the magnitude of the genetic parameters of initial phase sugarcane progenies in the north coast of Pernambuco. Experimental works were developed during the agricultural year of 2006/2007 in the sugarcane plantation zone in the north coast of Pernambuco, in the district of Igarassu, in the area of the São José industrial plant. The experimental delineation was randomized blocks with five repetitions, using 24 genotypes as treatment (20 from the crossings and 4 standard varieties). The parcel was planted in three furrows of 6 m, spaced by 1.30 m with 10 seedlings per furrow (spaced by 0.6 m within the furrow), totalizing a total area of 23.4 m². Harvest was done in the 10th month after the transplantation, where were evaluated the following variables: pol tons per hectare (PTH), sugarcane tons per hectare (STH), fiber (FB), corrected pol % (CPP), purity (PTY), brix (BX) and total retrievable sugar (TRS). The progenies of the crossings: RB855035 X RB72454; RB865230 X RB855035; Tuc71-7 X RB 72454 and RB 72454X Tuc71-7, overtopped for most of the studied variables. There is genetical variability among the progenies of the crossings for all the evaluated variables. The h²m estimations were expressive for the variables STH, PTH, CPP, FB, BX and TRS, indicating the possibility of success in the selection of these variables within the sugarcane plantation region of North Coast of Pernambuco
