A citricultura no Brasil exerce um papel de grande importância econômica, social, gerando empregos, renda e desenvolvimento. O Brasil é o maior produtor mundial de citros, o Estado de Sergipe destaca-se em 5º lugar nacional em produção. Dentre os vários problemas fitossanitários enfrentados pela citricultura brasileira está a Clorose Variegada dos Citros (CVC), conhecida como amarelinho, causada pela bactéria Xylella fastidiosa Wells et al. A CVC foi identificada oficialmente no Brasil, em 1987, em pomares do Triângulo Mineiro e do Norte e Noroeste do Estado de São Paulo. No Nordeste, foi constatada em 1996 em Sergipe no município de Boquim, e em 1997 na Bahia, nos municípios de Rio Real e Itapicuru. O objetivo foi revisar a literatura sobre as espécies de cigarrinhas vetores da CVC, e verificar se ocorrem no estado de Sergipe. Os primeiros sintomas são vistos nas folhas, passam posteriormente para os frutos e acabam afetando toda a planta, e para serem percebidos pode levar entre 5 meses e 2 anos. Os principais vetores da X. fastidiosa em citros são as cigarrinhas da família Cicadellidae. No Brasil já foram confirmadas 12 espécies de cigarrinhas vetoras. Para o estado de Sergipe, são escassas a informações sobre Cicadellidae vetoras, os dados são limitados ao Litoral Norte da Bahia, com exceção de vaga citação sobre quatro gêneros (Oncometropia, Acrogonia, Dilobopterus e Homolodisca) e três espécies (Homolodisca ignorata Melichar, Acrogonia sp. e Homolodisca spottii Takiya, Cavichioli & McKamey). Citrus leafhoppers, Vectors of of Bacterium Xylella fastidiosa Wells et al.: Potential Pest of Citrus Crops in Sergipe State Abstract. The citrus industry in Brazil plays a role of great economic, social, generating jobs, income and development. Brazil is the largest producer of citrus, the State of Sergipe stands out in 5th place in national production. Among the many pest problems faced by Brazilian citrus is Citrus Variegated Chlorosis (CVC), known as the yellowing caused by the bacterium Xylella fastidiosa Wells et al. The CVC was officially identified in Brazil in 1987, in orchards of “Triângulo Mineiro” and North and northwest of the state of São Paulo. In the Northeast Region of Brazil, was found in 1996 in the municipality of Boquim Sergipe, and Bahia in 1997, the municipalities of Rio Real and Itapicuru. The aim was to review the literature on the species of leafhoppers vectors of CVC, and verify that occur in the state of Sergipe. The first symptoms are seen in the leaves, then go for the fruits and end up affecting the entire plant, and to be perceived can take between five months and two years. The main vectors of X. fastidiosa in citrus are the sharpshooters of the family Cicadellidae. In Brazil 12 sharpshooters species have already been confirmed. For the state of Sergipe, is scarce information about the Cicadellidae vectors, the data are limited to the northern coast of Bahia, except for vague quote about four genus (Oncometropia, Acrogonia, Dilobopterus and Homolodisca) and three species (Homolodisca ignorata Melichar, Acrogonia sp. and Homolodisca spottii Takiya, Cavichioli & McKamey).

Blood profiles were determined in 47 juvenile green turtles, Chelonia mydas, from São Paulo northern coast, Brazil. Twenty-nine were affected by fibropapillomas and 18 were tumor free. Complete gross and histopathologic examinations of the fibropapillo were performed in 21 green turtles. Biometrical data, size, location and amount of tumors were recorded. The papillomas varied in morphology, location, size, color and texture. We found hyperplastic stroma, rich in blood vessels and connective tissue with increase in thickness of the dermis. The tumors w0ere classified as papillomas or fibropapillomas according to their epithelial and/or stromal proliferation. The lowest Mean Corpuscular Hemoglobin (HCM) values were observed in affected turtles.

Twenty-one species of Acoela, including seven new species and one new subspecies, are reported from the northern coast of the state of São Paulo, Brazil. The species include two from the family Actinoposthiidae (Philactinoposthia coneyi sp. nov., P. stylifera brasiliensis subsp. nov.), three from Convolutidae (Amphiscolops evelinae, Convoluta henseni, Heterochaerus sargassi), three from Haploposthiidae (Haplogonaria sophiae sp. nov., Kuma albiventer, K. asilhas sp. nov.), eight from Isodiametridae (Archaphanostoma marcusi sp. nov., Avagina marci, Isodiametra divae, I. vexillaria, I. westbladi, Pseudaphanostoma divae, P. herringi sp. nov., Unnamed Species 1), one from Mecynostomidae (Eumecynostomum evelinae), three from Otocelididae (Haplocelis dichona, Otocelis erinae, sp. nov., Philocelis robrochai sp. nov.) and one from Paratomellidae (Paratomella rubra). The genera Haplocelis and Otocelis from the defunct family Otocelididae are reassigned to the family Isodiametridae.

This paper presents the results of the planform stability classification for the headland-bay beaches of the State of Santa Catarina and of the Northern Coast of São Paulo, based on the application of the Parabolic Bay-Shape Equation (PBSE) to aerial images of the beaches, using the software MEPBAY®. For this purpose, georeferenced mosaics of the QuickBird2® satellite imagery (for the State of Santa Catarina) and vertical aerial photographs (for the northern coast of São Paulo State) were used. Headland-bay beach planform stability can be classified as: (1) in static equilibrium, (2) in dynamic equilibrium, (3) unstable or (4) in a state of natural beach reshaping. Static equilibrium beaches are the most frequent along the coast of the State of Santa Catarina and the Northern Shore of São Paulo, notably along the most rugged sectors of the coast and those with experiencing lower fluvial discharge. By comparison, dynamic equilibrium beaches occur primarily on the less rugged sectors of the coast and along regions with higher fluvial discharge. Beaches in a state of natural beach reshaping have only been found in SC, associated with stabilized estuarine inlets or port breakwaters. However, it is not possible to classify any of these beaches as unstable because only one set of images was used. No clear relation was observed between a beach's planform stability and other classification factors, such as morphodynamics or orientation.

The aim of the present study was to evaluate the helminth fauna found in the Magellanic penguin, Spheniscus magellanicus, relating parasite population and community ecological parameters to life aspects of the host species. The study involved 237 specimens of S. magellanicus taken from the northern shore of the state of São Paulo (23° 46' S, 45° 57' W) and southern shore of the state of Rio de Janeiro (23° 02' S, 44° 13' W), Brazil. The following helminth fauna were found: the nematode Contracaecum pelagicum (core species), found in the stomach; the digenetic Cardiocephaloides physalis and the cestode Tetrabothrius lutzi (satellite species), both collected from the initial portion of the small intestine. Comparisons using the Shannon Diversity Index revealed that the parasite community in juvenile penguins is less diverse in the migratory season than the breeding season. Parasitological studies on penguins and other migratory animals provide important information on species during the time in which they remain pelagic and constitute a useful tool for the acquisition of data that is difficult to obtain through other means, thereby favoring the conservation of the species.

specimens of the zipper sand skate psammobatis extenta were collected in the region of ubatuba off the northern coast of the state of são paulo, brazil, monthly for one year (january–december 2000), at 25- to 40-m isobaths. a total of 123 individuals were caught. the total length (tl) of females averaged 224.6 mm, and of males 217 mm. the overall sex ratio was 1:1. analysis of the length–weight relationship indicated the existence of positive allometry in females, and isometry in males. the length at onset of sexual maturity was determined for both sexes; females reached sexual maturity at smaller sizes than males (tl50=230.7 and tl50=237.7 mm respectively). females showed functional parity of both ovaries and uteri. females that were pregnant or were carrying vitellogenic oocytes were observed during nine of the 12 months of the survey, indicating a continuous reproductive cycle. psammobatis extenta was most abundant from january to april, and again from june to october. most individuals were collected at the 40-m isobath. both adults and neonates were collected in the study area. however, adolescent skates were scarce, which either indicates differential occupation of the area, or suggests that the shallow waters of the continental shelf are used as breeding grounds.
