Filtros de precedência : agregação anónima de dados de trânsito bluetooth
Gonçalves, Nelson; Baquero, Carlos; José, Rui; Borges, MiguelÀ medida que os dispositivos Bluetooth se tornam cada vez mais comuns, existe um potencial crescente para tirar partido das capacidades desta tecnologia assim como das infraestruturas j a existentes para cen arios de rastreio massivo de dispositivos. Todavia, a recolha de informa c~ao destes equipamentos pode criar problemas de privacidade, pois a cria c~ao de um registo permanente e/ou desprotegido dos dados r...

Field capture of Thyanta perditor with pheromone-baited traps
Laumann,Raúl Alberto; Moraes,Maria Carolina Blassioli; Khrimian,Ashot; Borges,MiguelThe objective of this work was to evaluate the field attractiveness of Thyanta perditor synthetic sex pheromone-baited traps, its attractivity to other stink bug species, and the response of T. perditor to a geometric isomer of the sex pheromone. Two-liter transparent plastic bottles traps were baited with rubber septa impregnated with the treatments: 1 mg of methyl-(2E,4Z,6Z)-decatrienoate [(2E,4Z,6Z)-10:COOMe...
Egg parasitoid wasps as natural enemies of the neotropical stink bug Dichelops ...
Laumann,Raúl Alberto; Moraes,Maria Carolina Blassioli; Silva,Joseane Padilha da; Vieira,Afrânio Márcio Corrêa; Silveira,Samantha da; Borges,MiguelThe objective of this work was to determine the potential of five species of Scelionidae wasps - Telenomus podisi, Trissolcus basalis, Trissolcus urichi, Trissolcus teretis and Trissolcus brochymenae - as natural enemies of the neotropical stink bug Dichelops melacanthus, and to determine if the presence of eggs of other stink bug species influences the parasitism and development of the parasitoids. Two kinds o...
Euschistus heros mass rearing technique for the multiplication of Telenomus podisi
Silva,Cleonor Cavalcante; Laumann,Raul Alberto; Blassioli,Maria Carolina; Pareja,Martin; Borges,MiguelThe objective of this work was to improve the mass rearing technique of Euschistus heros in laboratory. Nymphs and adults were reared at densities 100, 200, 300 and 400 eggs per Petri dish (9 cm diameter), and at 50, 100, 150 and 200 couples per rearing cages (900 mL), respectively. Survival rate of immature stages and survivorship and reproduction of adults were determinated. Survivorship of nymph to adult was...
Evaluation of the lipophilic properties of opiolds, amphetamine-like drugs, and...
Rubin Gulaboski; Natália Cordeiro; Nuno Milhazes; Jorge Garrido; Fernanda Borges; Miguel Ângelo da Silva Jorge; Carlos Manuel de Melo PereiraFor the first time, the partition coefficients of the ionized forms of several opioids, amphetamine-like drugs, and their metabolites were determined by studying their ionic transfer process across the bare interface water/organic solvent. The ionic partition coefficients of the monocationic forms of 12 compounds heroin, 6-monoacetylmorphine (6-MAM), morphine, acetylcodeine, codeine, dihydrocodeine, methampheta...
Sensory response of the egg parasitoid Telenomus podisi to stimuli from the bug...
Silva,Cleonor Cavalcante; Moraes,Maria Carolina Blassioli; Laumann,Raúl Alberto; Borges,MiguelThe objective of this work was to study the foraging behavior of Telenomus podisi Ashmead (Hymenoptera: Scelionidae) in the presence of stimuli from its host, Euschistus heros (Heteroptera: Pentatomidae). The stimuli selected were: egg mass; virgin males and females; volatile extracts of sexually mature males and females; components of male sex pheromone; a component of the alarm pheromone, hexane and an empty ...
A push infrastructure for mobile application deployment in mobile environments
Ribeiro, António Nestor; Campos, J. Creissac; Borges, MiguelMobile devices tend to be a synonym of variety. Variety both in hard- ware capabilities and software act as restrictions to software development and deployment. Other restrictions arise from their condition of mobility, environ- mental conditions such as bandwidth, coverage availability, lighting and avail- ability of services. In that perspective, this work intends to explore the possibility of a model of appl...
Detection of beetle damage in forests by X-ray CT image processing
Cruvinel,Paulo Estevão; Naime,João de Mendonça; Borges,Miguel; Macedo,Álvaro; Zhang,AijunSome beetle species can have devastating economic impacts on forest and nursery industries. A recent example is Anophophora glabripennis, a species of beetle known in the United States as the ''Asian Longhorrned beetle'', which has damaged many American forests, and is a threat which can unintentionally reach south American countries, including Brazil. This work presents a new method based on X-ray computerized...
Inter and intra-guild interactions in egg parasitoid species of the soybean sti...
Sujii,Edison Ryoiti; Costa,Maria Luiza Marcico; Pires,Carmen Silvia Soares; Colazza,Stefano; Borges,MiguelThe objective of this research was to evaluate the parasitism behavior of Telenomus podisi Ashmead, Trissolcus basalis (Wollaston) e Trissolcus urichi Crawford (Hymenoptera: Scelionidae) on eggs of Nezara viridula L., Euschistus heros F., Piezodorus guildinii Westwood and Acrosternum aseadum Rolston (Heteroptera: Pentatomidae), in no choice and multiple choice experiments. For all parasitoid species, the result...
