The fall armyworm is a pest that feeds on various botanies species. The objective of this experiment was to study the biology of this pest in corn and cassava leaves. Caterpillars were collected in area under cultivation with cassava and maintained on artificial diet for two generations. Under controlled conditions in a climatic chamber (B.O.D) in the laboratory (25 degrees, 60 +/- 10% RH and photophase 14 hours) were evaluated daily 50 caterpillars in corn treatments and 50 in cassava, where duration and viability of the larval phase and pupal, weight of pupas were observed after 24 hours, deformation percentage of pupas and adults, longevity, fecundity and total life cycle. The viability of larvae fed on leaves of maize and cassava was 74% and 60%, respectively. The larval period of the insects was shorter in maize 16.89 days (seven instars) and cassava 20.08 days (six instars). The pupal phase lasted 11.42 days in cassava treatment and 10.87 in the maize. The pupal weight of females and males was higher in corn 204.91 mg and 198.97 mg, respectively. The biological cycle varied depending on the ingested food. Adult longevity lasted 9.88 days for insects fed on cassava leaves. Therefore, cassava affected the development of S. frugiperda.

Este estudo, de natureza qualitativa, teve por objetivo investigar os aspectos relevantes que direcionam a opção e a organização das atividades propostas durante as vivências com recreação, aplicadas no âmbito do lazer por profissionais coordenadores de hotéis, de acampamentos e atuantes do programa Super-férias oferecido pelo SESI (Sistema S, focalizando-se, especificamente, o SESI de Rio Claro). Para tanto, o estudo constituiu-se da união de pesquisa bibliográfica e pesquisa exploratória, durante a qual foi utilizada entrevista semi estruturada, como instrumento para coleta de dados. Os dados foram analisados descritivamente, por meio da técnica de Análise de Conteúdo Temático, tendo sido criados 3 eixos temáticos: Intervenção Profissional, Atividades Recreativas e Participantes. Os resultados apontam para a necessidade de um perfil geral e específico, para atuar com recreação, sendo que algumas características surgem como primordiais,como, pró atividade, responsabilidade e boa comunicação. Notou-se que existem carências na atuação profissional, às vezes, devido à qualificação, seja, em âmbito acadêmico, seja, dentro dos próprios estabelecimentos, que utilizam métodos de treinamento que ocasionam na perda dos aspectos pedagógicos inerentes às atividades, tendo em vista que, embora os elementos pedagógicos estejam presentes, eles não são compreendidos, pelos profissionais, em sua totalidade, tornando a atuação do profissional praticista. Quanto à elaboração de atividades recreativas, percebeu-se a presença de alguns valores educacionais, porém, nem sempre permeiam efetivamente durante a prática profissional. Notou-se ainda, nas atividades, a existência de estruturas básicas, com objetivos pré-estabelecidos, organização e execução planejados. Quanto à renovação do programa de atividades notou-se que esta acontece semestralmente visando apresentar novidades aos participantes. Pode-se...

Introduction: The zygomatic maxillary complex is the second most affected area of the face due to injuries, surpassed only by the nasal bones. The zygomatic arch fracture is under the direct action of trauma (punch, head butt), its fragile structure, losing its normal convex curvature in the temporal area. Objective: To report a case, using a reduction technique of zygomatic arch fracture using a hook or Ginestet Barros. Case report: A male patient, 25 years of age, leukoderma, showing zygomatic arch fracture right. The patient underwent closed reduction with the hook adapted to the skin. The patient was instructed to keep care of the region for at least four weeks

The Morse Taper implant system, developed from its introduction in engineering, has become increasingly effective for use in dentistry. However, other systems, main external hexagon type, have been used more frequently today. Current studies have been reported the positive features of the Morse taper system and even emphasized as ideal within the systems used in implantology. Unfortunately, some professional duty by not knowing this system, or even prefer hexagon type system by decreased cost of components, have refused to use it. Thus, this study was aimed to perform a brief review of the Morse taper system, emphasizing its main points of interest in dentistry, in an attempt to familiarize the professionals to at least learn more about this system that has the prospect to become the leading system implants used in dentistry in the coming years. It is concluded that this system of dental implants is favorable showing predictability and success.

Introduction: The request of three-dimensional images (3D) of the dentomaxillofacial complex has increased. Hence, new possibilities for assessment, treatment as well as follow-up after treatment have increased their importance with the use of cone beam computed tomography (CBCT). The images in two dimensions (2D) have inherent problems that can be solved with treedimensional images assessment. Objectives: To clarify the main doubts about the operational mechanism of complementary diagnostic method; to explain the advantages and disadvantages, to discuss the effective radiation dose and possible applications in orthodontia. Conclusion: The information generated by 2D images from the CBCT does not show differences that may endanger the orthodontic planning when compared with the images of 2D conventional radiographs. The effective radiation dose received by the patient should not be considered as a limiting factor of the tomography exam request.

The aim of this study was to analyze the perception of elderly caregivers in relation to the meaning of general and oral health and about oral health status of the institutionalized aged. It was performed a qualitative study, using Discourse of Collective Subject method. It were interviewed 42 caregivers who worked in longterm care facilities of Araçatuba City, SP and Passo Fundo City, RS – Brazil, applying a structured questionnaire. The interviews were recorded and transcript to be performed the qualitative analysis. The answers were analyzed and them it was elaborated the discourses of collective subject (DCS). Oral health, according to caregivers, was hygiene habits and good diet, while the absence of oral health was sequelae of oral diseases. It's possible to note that older means of health were being substituted by new perceptions of quality of life and is very divergent between older professionals and those who graduated during last two decades. However, according to caregivers, this health perception as quality of life was not included in Dentistry, where the old mean "absence of symptoms" was prevalent. For part of them, the institutionalized elderly have no oral health and the only way to improve their condition was through clinical attendance.

Aim: To analyze dental students' view concerning Oral Health Education. Materials and Methods: The present research, using both qualitative and quantitative approaches, addresses aspects related to dental students' understanding of Oral Health Education, the value that they attach to this practice in the school environment, as well as the importance of their participation in these and other activities during their studies in dentistry. Results: Although dental students recognize the importance of Oral Health Education in the school environment,as well as the importance of their own participation within these activities, their perception of "Oral Health Education" is reductionist and focused primarily on the disease. Conclusion: It is well-known that these findings are reflections and consequences of an established context within a university education. It is therefore necessary that these professional educators perform an in-depth rethinking of the dental practice, in an attempt to develop methodologies based on Health Education in their own teaching practices.
