Efeito de beauveria bassiana (bals.) Vuillemin eMetarhizium anisopliae (metsch.) sorokin nos parâmetros biológicos de trichogramma atopovirilia oatman & platner, 1983 (hymenoptera: trichogrammatidae)

Two bioassays were performed to evaluate the effect of two biopesticides based on Beauveria bassiana (Bals.) Vuillemin and Metarhizium anisopliae (Metsch.) Sorokin on the biological parameters of Trichogramma atopovirilia Oatman & Platner, 1983. In the first one, displays with S. frugiperda, 1797 eggs were dropped into the biopesticide suspension and offered to the parasitoid females for 24 hours. In the second one, parasitoid females were fed with a suspension containing honey and biopesticide suspension. In both cases, after the parasitoid death they were mantained into a humid chamber to observe fungus sporulation. The experiments were maintained in a climatized chamber at 25 +/- 1 degrees C, RH 70 +/- 10%, and photophase of 14 hours. The longevity and adult mortality, total parasitism, progeny emergency, number of individuals per egg and sexual ratio were analyzed. The biopesticides did not affect the evaluated parameters and no fungus sporulation was observed in dead females. It is possible to assert that the entomopathogenic fungi B. bassiana and M. anisopliae can be used with T. atopovirilia in IPM S. frugiperda systems.

Toxicidade diferencial de produtos à base de abamectina ao ácaro Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) em citros

O ácaro Brevipalpus phoenicis é uma das principais pragas dos citros por ser vetor do Citrus Leprosis Virus (CiLV), agente causal da leprose, uma das mais graves doenças da citricultura. Objetivou-se avaliar o efeito tóxico de produtos à base de abamectina sobre o ácaro B. phoenicis. Foram realizados um experimento de ação direta e três de ação residual no Laboratório de Acarologia do Departamento de Proteção de Plantas (Fitossanidade) da FCAV - UNESP, Jaboticabal-SP. O delineamento adotado nos bioensaios foi o inteiramente casualizado, onde 10 tratamentos foram repetidos 7 vezes, sendo cada repetição composta por um fruto de laranja. Os tratamentos estudados (mL p.c./100 L de água) foram: Acaramik a 20; 30; 40 e 50 mL; Vertimec a 30 e 40 mL; Abamectin Nortox a 30 e 40 mL; Tricofol a 77 mL e uma testemunha sem aplicação. Utilizaram-se frutos com presença de verrugose, que foram lavados e parcialmente parafinados, deixando-se uma área sem parafina, que foi circundada com cola entomológica para contenção dos ácaros. Transferiram-se 20 ácaros adultos B. phoenicis para cada fruto. No bioensaio de ação direta, a transferência foi realizada antes das aplicações e, nos bioensaios de ação residual, aos 5; 10 e 15 dias após a aplicação dos produtos. A aplicação dos produtos sobre os frutos foi realizada em Torre de Potter. Os resultados obtidos nos bioensaios evidenciaram que os melhores tratamentos foram: Tricofol a 77 mL, Acaramik a 40 e 50 mL e Vertimec a 40 mL. de forma geral, os produtos testados podem ser utilizados no controle do ácaro B. phoenicis.

Fatores influenciadores da implementação de ações de gestão de segurança da informação :um estudo com executivos e gerentes de tecnologia da informação das empresas do Rio Grande do Norte

Information is one of the most valuable organization s assets, mainly on a global and highly competitive world. On this scenery there are two antagonists forces: on one side, organizations struggle for keeping protected its information, specially those considered as strategic, on the other side, the invaders, leaded by innumerous reasons - such as hobby, challenge or one single protest with the intention of capturing and corrupting the information of other organizations. This thesis presents the descriptive results of one research that had as its main objective to identify which variables influence the Executives´ and CIOs´ perceptions toward Information Security. In addition, the research also identified the profile of Rio Grande do Norte s organizations and its Executives/CIOs concerning Information Security, computed the level of agreement of the respondents according to NBR ISO/IEC 17799 (Information technology Code of practice for information security management) on its dimension Access Control. The research was based on a model, which took into account the following variables: origin of the organization s capital, sector of production, number of PCs networked, number of employees with rights to network, number of attacks suffered by the organizations, respondent´s positions, education level, literacy on Information Technology and specific training on network. In the goal´s point of view, the research was classified as exploratory and descriptive, and, in relation of the approach, quantitative. One questionnaire was applied on 33 Executives and CIOs of the 50 Rio Grande do Norte s organizations that collected the highest taxes of ICMS - Imposto sobre Circulação de Mercadorias on 2000. After the data collecting, cluster analysis and chi-square statistical tools were used for data analysis. The research made clear that the Executives and CIOs of Rio Grande do Norte s organizations have low level of agreement concerning the rules of the NBR ISO/IEC 17799. It also made evident that the Executives and CIOs have its perception toward Information Security influenced by the number of PCs networked and by the number of attacks suffered by the organizations

Sistema de gerência de informação de processos industriais via Web

The structure of Industrial Automation bases on a hierarchical pyramid, where restricted information islands are created. Those information islands are characterized by systems where hardware and software used are proprietors. In other words, they are supplied for just a manufacturer, doing with that customer is entailed to that supplier. That solution causes great damages to companies. Once the connection and integration with other equipments, that are not of own supplier, it is very complicated. Several times it is impossible of being accomplished, because of high cost of solution or for technical incompatibility. This work consists to specify and to implement the visualization module via Web of GERINF. GERINF is a FINEP/CTPetro project that has the objective of developing a software for information management in industrial processes. GERINF is divided in three modules: visualization via Web, compress and storage and communication module. Are presented results of the utilization of a proposed system to information management of a Natural Gas collected Unit of Guamar´e on the PETROBRAS UN-RNCE.

Comparison of four trap types for ambrosia beetles (Coleoptera, Scolytidae) in Brazilian Eucalyptus stands

Eucalyptus spp. plantations represent >60% of the reforested area in Brazil. Although ambrosia beetle attacks on live trees were at first nonexistent, they have begun to appear with greater frequency. Monitoring for pest insects is a key factor in integrated pest management, and baited traps are one of the most widely used methods for insect population detection and survey. We compared the efficiency of the most widely used trap in Brazil to survey for ambrosia beetles and other Scolytidae, the ESALQ-84 type, with other traditionally employed traps: the multiple funnel (Lindgren trap); drainpipe; and slot (Theyson) traps, in a Eucalyptus grandis Hill ex Maiden stand in Brazil. The ESALQ-84 trap was the most efficient in trapping Hypothenemus eruditus Westwood and Hypothenemus obscurus (F.); the multiple funnel trap caught significantly more Cryptocarenus diadematus Eggers; whereas the slot trap caught more Premnobius cavipennis Eichhoff and Xyleborus affinis Eichhoff than the other traps. The drainpipe trap was the least effective trap overall. When corrected for number of beetles caught per trap surface area, catches were significantly higher on the ESALQ-84 trap for the majority of the species analyzed, probably because of a smaller trap surface area. The slot trap was recommended for it caught overall more beetles of the three most economically important scolytid species in eucalypt plantations in Brazil, P. cavipennis, X. affinis, and X, ferrugineus.

A gestão do Sistema Único de Assistência Social em Currais Novos (RN)

The present paper analyses the social assistance management in small cities, starting from the reality of Currais Novos City. Its main objective is to analyse the management of this politic in the context of the Nacional Sistem of Social Assistance (SUAS) through the management instruments materialized in the city: Social Assistance Plan, Budget, Management Report, Information Management, Monitorizing and Evaluation. It reveals a discrepancy between the instruments purpose and their concretude, and it identifies the main challenges in order to make them real, revealing the contradictions of such politic, through which the advances relate with the retrocesses. It remarks, in this context, the debate about Public Management and some aspects of the trajetory of the Social Assistance management in the brazilian context and the configurations of (SUAS) and of the politics in Currais Novos city. Such path allows us to identify the feebleness in the city ways to adopt the (SUAS) criteria, which is much more effective in burocratic aspects than in the change of the Social Assistance conception and in the effective incorporation of the (SUAS) principles and guidelines. Thus, problems are identified in what concerns to the important aspects for its effectivation, with the human resources, financing and social control mechanisms. It makes possible to reafirm the importance of the analysed management instruments for the effectivation of one participative and democratic management, as well as the urgency of its materialization as one of the important ellements for this politic to happen as a right and to make a stop to the unconformities between the (SUAS) determinations and its materialization

Gestão da informação utilizando o método infomapping

A gestão da informação é extremamente importante para as organizações. O mapeamento informacional é um instrumento que pode ser utilizado no âmbito da gestão da informação. Para realizar o mapeamento informacional, pode-se utilizar o método denominado Infomapping, criado por Burk Jr. e Horton Jr., que se constitui em uma valiosa ferramenta para gerenciar os recursos de informação de uma organização. Ele permite descobrir com exatidão o grau de desconhecimento que se tem sobre as fontes, serviços e sistemas com os quais se desenvolve o trabalho informacional da organização. O processo consiste em criar um levantamento de todas as informações, que supostamente constituem-se num recurso informacional gerado internamente ou produzido externamente, que impactam diretamente as atividades corporativas.

O uso da informação contábil no setor sucroalcooleiro: um estudo nas indústrias de Alagoas

This study has the purpose of discussion and reflection of how the accounting information in the managemental area are used by the sugar & alcohol industry, located at State of Alagoas, aiming to identify if them please their managers expectations in the process of taking decision. Ahead of an existent universe of 27 (twenty seven) companies registered at the Sugar & Alcohol Labor Union of State of Alagoas SINDAÇUCAR files, were collected 14 (fourteen) questionnaires to support the current research classified as explorative and descriptive. The junction of these two kinds of research resulted in a quantitative and perceptive analysis of the use of the accounting information in the process of taking decision of the Sugar & Alcohol industry in Alagoas. The results demonstrated in this research indicate that, although the managers consider relevant the information at cost area, they do not use them in the process of taking decision. The reports emitted by accountancy are only financial, such as balance sheets, income statement, financial flow, among others factors. The importance order that the managers give to the accounting information and the kind of information that they use in the process of taking decision do not indicates that they use the accountancy in administration level. The statistics analysis of the files collected allows infer that the information provided by accountancy are considered important, however are few used at the manager process

Foraging Behavior of the Swarm-Founding Wasp, Polybia (Trichothorax) sericea (Hymenoptera, Vespidae): Prey Capture and Load Capacity

The main component of the protein diet of P. sericea was larvae of Lepidoptera (75.38%), with predominance of the following Families: Noctuidae (30.99%), Hesperiidae (19.01%); Pyralidae (19.01%) and Nymphalidae (11.98%). The average weight of the prey captured was 14.2 mg, a value equivalent to 24.7% of the average wasp weight. The average glucidic food load was 28.61 mg, corresponding to approximately half the wasp weight (49.64%). The weight of the load transported in the crop varied according to the food density, which, in turn, influenced the time spent in its collection (Pearson: n=64; r=0.64;p<0.05). Polybia sericea showed predatory interactions against Lepidopteran caterpillars, who are known to be agricultural pests. P. sericea has potential to be used in Integrated Pest Management.

Parasitism capacity of Telenomus remus Nixon (Hymenoptera: Scelionidae) on Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) eggs

Este trabalho estudou a capacidade de parasitismo de Telenomus remus Nixon (Hymenoptera: Scelionidae) em ovos de Spodoptera frugiperda (Smith) (Hymenoptera: Scelionidae) nas temperaturas de 15, 20, 25, 28, 31 e 35ºC objetivando usar esse inimigo natural em programas de controle biológico em culturas onde S. frugiperda é considerada praga. O parasitismo ocorrido nas primeiras 24 h foi de 60,90; 81,65; 121,05; 117,55 e 108,55 ovos parasitados por fêmea em massas ovos com aproximadamente 150 ovos, nas temperaturas de 15, 20, 25, 28 e 31ºC. Fêmeas de T. remus causaram mais de 80% do parasitismo dos ovos nas temperaturas de 15, 20, 25, 28 e 31ºC aos 5, 27, 8, 2 e 2 dias, respectivamente. Na temperatura de 35ºC não houve parasitismo. As maiores taxas de parasitismo ocorreram nas temperaturas de 20, 25, 28 e 31ºC. A longevidade média de fêmeas de T. remus nas temperaturas compreendidas entre 15 e 31ºC variou de 15,5 a 7,7 dias. A temperatura máxima testada (35ºC) foi inadequada ao desenvolvimento de T. remus, sendo que nessa temperatura as fêmeas apresentaram longevidade bastante reduzida (1,7±0,02 dia) e não houve emergência de adultos. Todas as curvas de sobrevivência para T. remus foram do tipo I o que mostram que para todas as temperaturas há um aumento da taxa de mortalidade com o tempo.
