Ocorrência da Mosca-negra-dos-citros (Aleurocanthus woglumi ashby) (Hemiptera: aleyrodidae) em Pernâmbuco

This paper aimed to verify the presence of black-fly of citrus in the state of Pernambuco in Brazil and wordwide. The material with symptoms were collected in the metropolitan area of Recife/PE and subsequently led to the identification in the Insect Biology Laboratory of the Federal Rural University of Pernambuco - UFRPE on February 4, 2011. The samples collected from the branches of citrus and bilocular, found the presence of eggs, nymphs, "pupae" and adults of Aleurocanthus woglumi, confirming its occurrence in the state of Pernambuco. The presence of blackfly of citrus had been detected in the city in the state of Pernambuco as Timbauba, Bom Jardim, Macaparana, Axes, Orobo, Sao Vincent Farrer and Itambe in citrus plants. Before that had a suspect in the Valley Siriji/PE, now it is in the metropolitan area of Recife, therefore we can confirm that the material collected and identified in the metropolitan area of Pernambuco is A. woglumi.

Desempenho reprodutivo, características do pelame e taxa de sudação em vacas da raça Braford

Foram investigados os efeitos das características do pelame e da taxa de sudação (TS) sobre o intervalo de partos (IEP, n = 423) e os dias para o parto (DPP, n = 1.202) de vacas da raça Braford criadas em sistema extensivo em região tropical úmida no Mato Grosso do Sul, Brasil. As análises foram realizadas pelo método dos quadrados mínimos considerando para intervalo de partos os seguintes efeitos das classes de idade da vaca ao parto: grupo genético; pai; e regressão sobre a refletância da superfície da capa (R), a espessura da capa (E), o comprimento dos pêlos (C), o número de pêlos por unidade de área (N), o diâmetro dos pêlos (D) e a taxa de sudação. Para dias para o parto, foram considerados os efeitos: R, E, C, N, D, TS, divididos em classes; grupo genético; idade no início da estação de monta; e pai. Os componentes de variância e co-variância foram estimados pelo método de Máxima Verossimilhança Restrita sob o modelo touro. As características adaptativas não foram importantes para a variação do intervalo de parto e dos dias para o parto, mas a taxa de sudação apresentou efeito importante sobre dias ao parto. As estimativas de herdabilidade foram quase nulas para IEP e DPP e maiores para as características adaptativas (E = 0,16 ± 0,09; C = 0,18 ± 0,09; N = 0,08 ± 0,06; D = 0,12 ± 0,07; R = 0,30 ± 0,12; TS = 0,10 ± 0,06). Os resultados obtidos para as correlações genéticas de IEP e DPP com TS e entre as características do pelame indicaram que a seleção simultânea para menores valores de C pode ser favorável à redução do intervalo de partos. em geral, as correlações genéticas entre TS, IEP e DPP apresentaram elevado erro-padrão. Considerando os resultados deste estudo e a importância das características do pelame e da sudação, confirma-se a necessidade de se estudarem as correlações genéticas entre as características adaptativas e o desempenho reprodutivo para o progresso da adaptação de bovinos da raça Braford no Brasil.

Polimorfismo da transferrina e albumina e as associações com precocidade sexual em bovinos da raça Nelore doadores de sêmen

O presente estudo utilizou 16 animais Bos taurus indicus da raça Nelore doadores de sêmen. Estes animais foram divididos em grupos de acordo com a idade em que o sêmen congelou pela primeira vez. O grupo I, considerado precoce, apresentou animais com sêmen passível de congelação com idade inferior a 20 meses. O grupo II, composto por animais que tiveram o sêmen congelado com idade entre 21 e 26 meses. E o grupo III, tido como tardio, composto por animais com sêmen congelável com idade superior a 27 meses. Para análise dos padrões eletroforéticos da transferrina e albumina, amostras de sangue foram colhidas em tubos heparinizados e submetidos a centrifugação de 2.500 G por 15 minutos para separação do plasma sangüíneo. As amostras de plasma sangüíneo foram processadas para que a corrida eletroforética em gel de poliacrilamida pudesse ser realizada. Para a coloração do gel, usou-se Coomasie Brilliant Blue. Após análise dos padrões eletroforéticos da transferrina e albumina, observou-se que não houve relação detectável entre os fenótipos da albumina e precocidade sexual de touros doadores. Entretanto, em relação à transferrina, foi possível sugerir uma associação entre o alelo TfD com touros portadores de sêmen congelável precocemente ou medianamente em termos de idade à congelação.

Alterações do padrão ultrassonográfico do parênquima testicular em bovinos jovens da raça Nelore

The ultrasononographic examination of testicles is a noninvasive and rapid method that, allied to clinical examination, can lead to an early diagnostic of testicles disorders. The aim of the present study is to enhance andrologic evaluation and to make public altered ultrasonographic testicular parenchyma pattern in young Nelore bulls. Testes of 114 Nelore bulls from 9 to 15 months old were submitted to ultrasonographic evaluation (Frontal and transverse planes of testes). In this group, 111 animals presented testicular parenchyma with uniform pattern at low echogenicity, and the testicular echogenicity increased in proportion to the animal's age. Three animals, from 9 to 15 months old, presented heterogeneous testicular parenchyma with multiple hyperechoics

Composição de fibras musculares esqueléticas de eqüinos jovens da raça Brasileiro de Hipismo

The aim of this study was to typify the skeletal striated fibers of the gluteus medius muscle of young Brasileiro de Hipismo (BH) horses by means of histochemical analysis with m-ATPase and NADH-TR according to the sex and the biopsy depth. It was observed that the frequency (F;%) and the relative cross sectional area (RCSA;%) of the fibers type IIX were greater than the fibers type IIA, which F and RCSA were greater than the fibers type I. The comparison between sex and muscles depht, showed no significant difference in F and RCSA in the three types of fibers. The results of morphometry showed that the gluteus medius muscle has greater glycolitic metabolism and anaerobic capacity because of the presence of large proportion of type IIX fibers. This may be justified by the genetic influence of Thoroughbred in the formation of Brasileiro de Hipismo breed.

Parâmetros métricos da traqueia e suas correlações com o perímetro torácico, peso e comprimento corporal de cães sem raça definida (Canis familiaris, Linnaeus, 1758)

The present study aimed to analyze metric data from the trachea of dogs and to correlate them with the thoracic girth, body length and weight. We used 48 dogs of unknown breed, 19 males and 29 females. The animals were weighed and then body length, thoracic girth, length and diameter of the trachea, and the number of tracheal rings were measured. The weight of dogs ranged from 4.2 to 21.5 kg, body length from 40.6 to 81.0 cm and thoracic girth from 36.0 to 63.5 cm. The trachea exhibited a total number of tracheal rings between 32 and 43, length between 13.0 and 23.4 cm, diameter of the cervical portion between 11.0 and 23.5 mm and in the thoracic portion between 8.2 and 20.9 mm. We also evaluated the tracheal termination skeletopy, which maintained relations with the 2nd (2.0%), 3 (6.3%), 4 (20.8%) or 5 (12.5%) intercostal spaces, and with the 3rd (6.3%), 4th (35.4%) or 5th (16.7%) ribs. Strong positive correlations of tracheal length with body weight (rS = 0.756, p <0.001), body length (r = 0.808, p <0.001) and thoracic girth (r = 0.735, p <0.001) were found. Therefore, the anatomical study of the trachea provides morphological subsidies for the realization of clinical and surgical procedures in this organ, being an important tool in veterinary practice.

A educação escolar na comunidade negra de Sibaúma: a trajetória educacional da Escola Municipal Armando de Paiva

The black communities, nowadays known as quilombolas, have long been segregated in social and cultural distances in relation to other groups in the country. Gradually, the establishment of public policy has enabled the inclusion of these social communities in new instances, favoring the improvement of standards of learning. In order to know the route of the school in relation to its surroundings, this paper presents a reflection on the educational history of the Municipal School Padre Armando de Paiva, inserted in the context of afrodescendência (African descendants), in the community called Sibaúma, municipality of Tibau do Sul - RN, characterized as the object of this study. Methodologically, this study is limited in a descriptive research of the historical reconstruction of the school, a case considered worthy of analysis. From a reflection on the presence of African descent in Brazil and in Rio Grande do Norte, the study also presents information on education in Brazil. Finally, it presents the trajectories directed to the analysis of physical conditions, the dynamics of registration, and avoidance of repetition of its students and the qualifications of its teaching staff. Survey selected for analysis five-year academic periods, a series which began in the year nineteen eighty and ends in the year two thousand and ten

Zona adensável de Ponta Negra em Natal/ RN: as conseqüências decorrentes da lei complementar 27/2000 na visão dos moradores da área

The quarrel on the urban intensific use of determined areas of the city is carried through in some levels of the society, which had to the fact to bring direct influences the population that inhabits it. The question to become an area to intensific use, implies in determining that the local infrastructure has the capacity to take care of to a bigger amount of people, inhabitants or passers-by. In the quarter of Ponta Negra, in Natal city (state of RN), its condition of area to intensific use to the municipal Law 27/2000 happened due that it starts to allow a bigger level of occupation of part of the quarter. This law has a direct relation with the installation of a complementary infrastructure in the quarter, to put does not send to its complementation and maintenance, what it takes the consequences that are felt by the population. This work has as main objective the identification of the decurrent significant consequences of the creation of Ponta Negra s Intensific Use Zone, according to vision of the population of the quarter. The way followed for this involves the compatible bibliography research with the subject, analysis of documents that treat on the quarter, mappings of the area in search of a physical characterization and mainly, an application of questionnaire next to local population. In this questionnaire it is the main point of the necessary collection of data to the work, indicating the point of view of the population not only on the negative points, but also on the positive points that had happened since the creation of Intensific Use Zone. The answers indicate problems of natures social, infrastructure and enviromental, compatible with the problems of other areas that had passed the same for process, as point the studied bibliography, indicating imperfections in the planning process and maintenance of Ponta Negra s Intensific Use Zone
