Field capture of Thyanta perditor with pheromone-baited traps

The 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], the male sex pheromone of T. perditor; 1 mg of (2E,4Z,6Z)-10:COOMe protected from sunlight in standard PVC plumbing pipe; 1 mg of its geometric isomer [(2E,4E,6Z)-10:COOMe]; and traps with rubber septa impregnated with hexane (control). The experiment was carried out in field during the soybean reproductive stages. Traps were monitored weekly, and the captures were compared to the population density estimated by the sampling cloth and visual inspection monitoring techniques. Traps baited with the sex pheromone, protected or not, were more effective in capturing T. perditor than traps baited with the isomer or the hexane. Thyanta perditor sex pheromone showed cross-attraction to other stink bug species, such as Euschistus heros, Edessa meditabunda, Piezodorus guildinii and Nezara viridula. Pheromone-baited traps can be used in population monitoring and to identify the relative composition of stink bug guilds.

Economic analysis of an agrosilvipastoral system for a mountainous area in Zona da Mata Mineira, Brazil

The objective of this work was to evaluate the economic viability of an agrosilvipastoral system developed for Zona da Mata mountainous areas in Minas Gerais state, Brazil, as well as to compare different options for wood (Eucalyptus grandis and Acacia mangium) commercialization of the second thinning. The data were obtained from a 10 year-old agrosilvipastoral system established in four hectares at Embrapa Gado de Leite station in Coronel Pacheco, MG, Brazil. As evaluation criteria for the economic viability analysis, the adopted methods were the net present value (NPV) and the internal rate of return (IRR), both calculated at 6% interest rate. Despite the small difference, adding value to forest products increased the attractiveness of the proposed system. Considered separately, the agricultural activity was impracticable, whereas the forestry and livestock activities were independently viable. The studied system seems to be equally tolerant to price variations for forest and livestock products, as well as strongly tolerant to variations in production costs.

The role of vectors in the epidemiology of avian malaria

Studies on host-parasite relationships have commonly reported that parasitized hosts undergo changes in their behavioural and life history traits. How do these changes affect the fitness of the hosts? What are the ecological and evolutionary drivers of these changes? These open questions are crucial to predict the parasite spread amongst hosts. Surprisingly, mosquito vectors of diseases to humans and animals have long been seen as passive parasite transporters, being unaffected by the infection though they also function as hosts. Natural parasite-vector interactions are therefore poorly documented in the literature. In this thesis, we seek to address the role of wild vectors in the epidemiology of avian Plasmodium, the etiological agents of malaria in birds. We first conducted avian malaria surveys in field-caught mosquitoes to identify the natural vectors in our temperate study area. We report that ornithophilic Culex pipiens primarily act as a vector for Plasmodium vaughani in spring, this parasite species being progressively replaced by P. relictum along with the season. Season-related factors may thus shape the mosquitoes' vectorial capacity. We then used experimental approaches to determine the effect of avian malaria on wild, naturally infected C. pipiens. We show that infected mosquitoes incur unavoidable physiological costs associated with parasite exploitation, these costs being expressed as a reduced survival under nutritionally stressed conditions only. These results are of significant importance for the epidemiology of avian malaria since seasonal changes in climate may likely influence food quality and quantity available to the mosquitoes. The host-selection preferences of the vectors with respect to the malaria-infection status of their bird hosts largely determine the disease spreading. In a second laboratory experiment, we thus offered wild C. pipiens the opportunity to choose between uninfected and naturally infected great tits, Parus major. We show that host-seeking mosquitoes have innate orientation preferences for uninfected birds. This suggests that avian malaria parasites exert strong selective pressures on their vectors, pushing them to evolve anti-parasite behaviours. We lastly investigated the links between malaria-associated symptoms in birds and resulting attractiveness to the mosquitoes. We show that experimentally malaria-infected canaries, Serinus canaria, suffer severe haematocrit reduction at peak parasitaemia and reduced basal metabolic rate later in the course of the infection. However, no links between infection and bird attractiveness to the mosquitoes were shown in an experiment using canaries as live bait for mosquito trap in the field. These links may have been masked by confounding environmental factors. Using a system where the vectors, parasites and hosts co-occur in sympatry, this thesis illustrates that vectors are not always Plasmodium permissive, which opposes to the traditional view that malaria parasites should have little effect on their vectors. The way that the vectors respond to the parasite threat is largely determined by the environmental conditions. This may have major implications for the epidemiology of avian malaria. - Les études portant sur les relations hôtes-parasites mentionnent souvent que les hôtes parasités subissent des modifications de leurs traits d'histoire de vie ou bien comportementaux. Comment ces changements affectent-ils la valeur sélective des hôtes et celle de leurs parasites ? Quels sont les déterminants de ces modifications ? Ces questions sont d'un grand intérêt en épidémiologie. Pour autant, les moustiques vecteurs de maladies infectieuses ont longtemps été perçus comme de simples transporteurs de parasites, n'étant pas affectés par ces derniers. Cette thèse porte sur le rôle des vecteurs dans l'épidémiologie des Plasmodium aviaires, agents étiologiques de la malaria chez les oiseaux. Dans le but d'identifier les vecteurs naturels de malaria aviaire dans notre zone d'étude, nous avons tout d'abord collecté des moustiques sur le terrain, puis déterminé leur statut infectieux. Nous rapportons que les moustiques Culex pipiens sont principalement impliqués dans la transmission de Plasmodium vaughani au printemps, cette espèce de parasite étant progressivement remplacée par P. relictum au fil de la saison de transmission. Nous avons ensuite conduit une expérience visant à déterminer l'effet de la malaria aviaire sur des C. pipiens sauvages, naturellement infectés. Nous montrons que des coûts sont associés à l'infection pour les moustiques. Ces coûts occasionnent une diminution de la survie des vecteurs seulement lorsque ceux-ci sont privés de ressources nutritionnelles. Des changements saisonniers de climats pourraient affecter la quantité et la qualité des ressources disponibles pour les vecteurs et donc, leur aptitude à transmettre l'infection. Les traits comportementaux des moustiques vecteurs, tels que la recherche et le choix d'un hôte pour se nourrir, sont d'une importance majeure pour la dispersion de la malaria. Pour cela, nous avons offert à des C. pipiens sauvages l'opportunité de choisir simultanément entre une mésange charbonnière (Parus major) saine et une autre naturellement infectée. Nous montrons que les moustiques s'orientent préférentiellement vers des mésanges saines. Les Plasmodium aviaires exerceraient donc de fortes pressions de sélection sur leurs vecteurs, favorisant ainsi l'évolution de comportements d'évitement des parasites. Enfin nous avons cherché à identifier de potentiels liens entre symptômes de l'infection malarique chez les oiseaux et attractivité de ces derniers pour les moustiques. Nous montrons que des canaris (Serinus canaria) expérimentalement infectés sont fortement anémiés au moment du pic infectieux et que leur métabolisme basai diminue plus tard au cours de l'infection. Toutefois, aucun lien entre le statut infectieux et l'attractivité des canaris pour les moustiques n'a pu être montré lors d'une expérience réalisée en nature. Il se peut que ces liens aient été masqués par des facteurs environnementaux confondants. Dans son ensemble, cette thèse illustre que, contrairement aux idées reçues, les vecteurs de malaria aviaire ne sont pas toujours permissifs avec leurs parasites. L'environnement apparaît aussi comme un facteur déterminant dans la réponse des vecteurs face à la menace d'infection malarique. Cela pourrait fortement affecter l'épidémiologie de la malaria aviaire.

Antixenosis of bean genotypes to Chrysodeixis includens (Lepidoptera: Noctuidae)

The objective of this work was to evaluate bean genotypes for resistance to soybean looper (Chrysodeixis includens). Initially, free-choice tests were carried out with 59 genotypes, divided into three groups according to leaf color intensity (dark green, light green, and medium green), in order to evaluate oviposition preference. Subsequently, 12 genotypes with high potential for resistance were selected, as well as two susceptible commercial standards. With these genotypes, new tests were performed for oviposition in a greenhouse, besides tests for attractiveness and consumption under laboratory conditions (26±2ºC, 65±10% RH, and 14 h light: 10 h dark photophase). In the no-choice test with adults, in the greenhouse, the 'IAC Jabola', Arcelina 1, 'IAC Boreal', 'Flor de Mayo', and 'IAC Formoso' genotypes were the least oviposited, showing antixenosis-type resistance for oviposition. In the free-choice test with larvae, Arcelina 4, 'BRS Horizonte', 'Pérola', H96A102-1-1-1-52, 'IAC Boreal', 'IAC Harmonia', and 'IAC Formoso' were the less consumed genotypes, which indicates antixenosis to feeding. In the no-choice test, all genotypes (except for 'IAPAR 57') expressed moderate levels of antixenosis to feeding against C. includens larvae.

Advertising in Mobile Games - A Business Model Evaluation

Tämän tutkimuksen tavoitteena oli selvittää kuinka houkuttelevan liiketoimintamahdollisuuden mobiilipelit tarjoavat mainostusalustana. Tutkimus suoritettiin tapaustutkimuksena. Tutkimus aloitettiin määrittelemällä liiketoimintamalli, jonka jälkeen suoritettiin yleinen katsaus Suomen mobiilipelimarkkinoille. Tämän jälkeen arvoketju-, arvoverkko- sekä markkina-analyysin avulla selvitettiin liiketoimintamallin mahdollisuudet sekä rajoitukset. Tutkimukseen käytettiinteorettista viitekehystä joka pohjautui Hamelin liiketoimintamalliin, Porterin arvoketjuun sekä Alleenin arvoverkoon. Tutkimuksen tuloksena todettiin, että mainostaminen mobiilipeleissä tarjoaa liiketoimintamahdollisuuden ilman esteitä sentoteuttamiselle. Suomalaiset mobiilipelimarkkinat ovat kuitenkin pirstoutuneet,minkä johdosta tutkittu 'mainosten hallinta-alusta'-liiketoimintamalli aiheuttaa liian suuret integraatiokustannukset. Myös suuri määrä pelitoimittajia heikentää mallin tehokkuutta.

The incidence and selection of multiple mating in plants.

Mating with more than one pollen donor, or polyandry, is common in land plants. In flowering plants, polyandry occurs when the pollen from different potential sires is distributed among the fruits of a single individual, or when pollen from more than one donor is deposited on the same stigma. Because polyandry typically leads to multiple paternity among or within fruits, it can be indirectly inferred on the basis of paternity analysis using molecular markers. A review of the literature indicates that polyandry is probably ubiquitous in plants except those that habitually self-fertilize, or that disperse their pollen in pollen packages, such as polyads or pollinia. Multiple mating may increase plants' female component by alleviating pollen limitation or by promoting competition among pollen grains from different potential sires. Accordingly, a number of traits have evolved that should promote polyandry at the flower level from the female's point of view, e.g. the prolongation of stigma receptivity or increases in stigma size. However, many floral traits, such as attractiveness, the physical manipulation of pollinators and pollen-dispensing mechanisms that lead to polyandrous pollination, have probably evolved in response to selection to promote male siring success in general, so that polyandry might often best be seen as a by-product of selection to enhance outcross siring success. In this sense, polyandry in plants is similar to geitonogamy (selfing caused by pollen transfer among flowers of the same plant), because both polyandry and geitonogamy probably result from selection to promote outcross siring success, although geitonogamy is almost always deleterious while polyandry in plants will seldom be so.

Project Success through Effective Decisions: Case Studies on Project Goal Setting, Success Evaluation and Managerial Decision Making

The objective of the thesis is to structure and model the factors that contribute to and can be used in evaluating project success. The purpose of this thesis is to enhance the understanding of three research topics. The goal setting process, success evaluation and decision-making process are studied in the context of a project, business unitand its business environment. To achieve the objective three research questionsare posed. These are 1) how to set measurable project goals, 2) how to evaluateproject success and 3) how to affect project success with managerial decisions.The main theoretical contribution comes from deriving a synthesis of these research topics which have mostly been discussed apart from each other in prior research. The research strategy of the study has features from at least the constructive, nomothetical, and decision-oriented research approaches. This strategy guides the theoretical and empirical part of the study. Relevant concepts and a framework are composed on the basis of the prior research contributions within the problem area. A literature review is used to derive constructs of factors withinthe framework. They are related to project goal setting, success evaluation, and decision making. On the basis of this, the case study method is applied to complement the framework. The empirical data includes one product development program, three construction projects, as well as one organization development, hardware/software, and marketing project in their contexts. In two of the case studiesthe analytic hierarchy process is used to formulate a hierarchical model that returns a numerical evaluation of the degree of project success. It has its origin in the solution idea which in turn has its foundation in the notion of projectsuccess. The achieved results are condensed in the form of a process model thatintegrates project goal setting, success evaluation and decision making. The process of project goal setting is analysed as a part of an open system that includes a project, the business unit and its competitive environment. Four main constructs of factors are suggested. First, the project characteristics and requirements are clarified. The second and the third construct comprise the components of client/market segment attractiveness and sources of competitive advantage. Together they determine the competitive position of a business unit. Fourth, the relevant goals and the situation of a business unit are clarified to stress their contribution to the project goals. Empirical evidence is gained on the exploitation of increased knowledge and on the reaction to changes in the business environment during a project to ensure project success. The relevance of a successful project to a company or a business unit tends to increase the higher the reference level of project goals is set. However, normal performance or sometimes performance below this normal level is intentionally accepted. Success measures make project success quantifiable. There are result-oriented, process-oriented and resource-oriented success measures. The study also links result measurements to enablers that portray the key processes. The success measures can be classified into success domains determining the areas on which success is assessed. Empiricalevidence is gained on six success domains: strategy, project implementation, product, stakeholder relationships, learning situation and company functions. However, some project goals, like safety, can be assessed using success measures that belong to two success domains. For example a safety index is used for assessing occupational safety during a project, which is related to project implementation. Product safety requirements, in turn, are connected to the product characteristics and thus to the product-related success domain. Strategic success measures can be used to weave the project phases together. Empirical evidence on their static nature is gained. In order-oriented projects the project phases are oftencontractually divided into different suppliers or contractors. A project from the supplier's perspective can represent only a part of the ¿whole project¿ viewed from the client's perspective. Therefore static success measures are mostly used within the contractually agreed project scope and duration. Proof is also acquired on the dynamic use of operational success measures. They help to focus on the key issues during each project phase. Furthermore, it is shown that the original success domains and success measures, their weights and target values can change dynamically. New success measures can replace the old ones to correspond better with the emphasis of the particular project phase. This adjustment concentrates on the key decision milestones. As a conclusion, the study suggests a combination of static and dynamic success measures. Their linkage to an incentive system can make the project management proactive, enable fast feedback and enhancethe motivation of the personnel. It is argued that the sequence of effective decisions is closely linked to the dynamic control of project success. According to the used definition, effective decisions aim at adequate decision quality and decision implementation. The findings support that project managers construct and use a chain of key decision milestones to evaluate and affect success during aproject. These milestones can be seen as a part of the business processes. Different managers prioritise the key decision milestones to a varying degree. Divergent managerial perspectives, power, responsibilities and involvement during a project offer some explanation for this. Finally, the study introduces the use ofHard Gate and Soft Gate decision milestones. The managers may use the former milestones to provide decision support on result measurements and ad hoc critical conditions. In the latter milestones they may make intermediate success evaluation also on the basis of other types of success measures, like process and resource measures.

Comparison of lures loaded with codlemone and pear ester for capturing codling moths, Cydia pomonella, in apple and pear orchards using mating disruption

Studies were conducted in apple, Malus domestica Borkhausen and pear, Pyrus communis L. (Rosales: Rosaceae), orchards to evaluate the attractiveness of grey halobutyl septa loaded with 1 (L2) and 10 (Mega) mg of codlemone, 8E,10E-dodecadien-1-ol, 3 mg of pear ester, ethyl (E,Z)- 2,4-decadienoate (DA2313), and 3 mg of pear ester plus 3 mg of codlemone (Combo) to adult codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae). All studies were conducted in orchards treated with pheromone mating disruption. All four lures were tested on diamond-shaped sticky traps placed in 60 plots of apple and 40 plots of pears in 2003/04, and in 62 plots of apples and 30 of pears in 2004-05. Combo lures attracted significantly more moths (males + females) than all the others in both years. Comparisons among flights showed significant differences mainly for flight 1 and 2, but not always for flight 3. Mega lures provided no significant improvement compared with L2 lures during both seasons regarding the total number of moths. Combo and DA2313 lures attracted fewer females than males during the whole season. For most sample dates, more virgin than mated females were attracted to Combo lures, except during the third flight, and the overall ratio was 60:40, although the difference was not statistically significant. We conclude that the Combo lures are better indicators of codling moth activity in pheromone treated orchards, regardless of pest population level, when compared with similar lures containing codlemone or pear ester alone.

Kriteereiksi avainasiakkaiden tunnistamiseen valittiin asiakkaan vuotuinen ostovolyymi, asiakkaan business-potentiaali sekä case-yrityksen toimittajaosuus. Asiakkaat luokiteltiin avainasiakkaisiin, kehitettäviin avainasiakkaisiin, ylläpidettäviin asiakkaisiin sekä satunnaisiin asiakkaisiin. Tutkimus tarjosi lähtökohdan case-yrityksen uusille avainasiakaspäälliköille sekä osoitti suunnan tulevaisuuden tutkimustarpeille. Aktiivisen tiedonvaihdannan kautta eri myyntikonttoreiden johtohenkilöstön sekä myös yrityksen eri funktionaalisten divisioonien välillä voidaan saavuttaa kilpailuetua kun lähestytään asiakasta toimintojaan järkiperäisesti koordinoineena toimittajana samalla kun asiakkaat keskittävät ostojaan. Jotta yrityksen tavoitteet, markkinamahdollisuudet sekä resurssit olisivat hyvin tasapainossa, tulisi myös asiakaskannattavuutta sekä asiakkaiden strategista merkittävyyttä arvioida ja mitata säännöllisesti tässä tutkimuksessa käytettyjen tunnistuskriteereiden lisäksi.

The conditions for the reproduction of the SAGUAPAC water cooperative in the city of Santa Cruz de la Sierra, Bolivia : discourse analysis

The SAGUAPAC cooperative in the city of Santa Cruz de la Sierra (Eastern Bolivia) is regularly presented as an example of cooperative successes regarding water supply and sanitation. Its efficiency, both economic and technical, is widely considered as the main reason for its attractiveness. However, without denying its importance, we show, through a discourse analysis from and about SAGUAPAC in local media, that moral and non-instrumental factors are crucial in the reproduction of the cooperative. These factors create attachment and affection toward the cooperative, through a storytelling using a four-dimensional rhetoric (mythification, identification, emotionalisation and personification). This storytelling technique, internalized in the local media discourse and materializing the so-called new spirit of capitalism, exploits the affects and instrumentalisation of local myths and legends, as well as the 'camba' ethnic identity. In that, it tends to retain SAGUAPAC members and to canvass new ones, by providing them with recognition in their quality of local community members. However, the mobilisation of social norms and power hierarchies might end up reinforcing the social exclusion of Andean non-camba immigrants, inspite of an a priori inclusive and democratic organisation.

Internationalization dynamics in the Swiss Corporate Tax Reform III

Over the last years, in a context of international tax competition, international and regional institutions such as the G20, the OECD, and the European Union are redefining what is acceptable in terms of corporate fiscal policy. Certain Swiss preferential tax treatments are considered by the above-mentioned institutions as harmful tax practices. As a consequence, the Swiss government has planned a third corporate tax reform (CTR III). The objective of this reform is to ensure international acceptability of the corporate tax system without prejudicing local public finances and Swiss corporate tax attractiveness. Therefore, we can posit that the CTR III is an internationalized object influenced by both regulation trends and tax competition framework. The main purpose of this paper is to provide elements of answer on how the currently discussed CTR III is influenced by the international environment, by focusing on its content as well as the reactions and positions of local stakeholders. With the help of internationalization literature, two distinct internationalization processes have been identified through the propositions of compliance measures with internationally-defined standards and competitiveness-enhancing measures. With regard to the configuration of local actors, the degree of conflict seems to be rather high. The current content of the reform is supported by the business community and right-wing parties and rejected by the unions and the Socialist Party.

Beyond pure public and pure private management models: Partial privatization in the European airport industry

The use of private funding and management is enjoying an increasing trend in airports. The literature has not paid enough attention to the mixed management models in this industry, although many European airports take the form of mixed public-private companies, where ownership is shared between public and private sectors. We examine the determinants of the degree of private participation in the European airport sector. Drawing on a sample of the 100 largest European airports, we estimate a multivariate equation in order to determine the role of airport characteristics, fiscal variables, and political factors on the extent of private involvement. Our results confirm the alignment between public and private interests in partially privatized airports. Fiscal constraints and market attractiveness promote private participation. Integrated governance models and the share of network carriers prevent the presence of private ownership, while the degree of private participation appears to be pragmatic rather than ideological.
