Biological Control of Ceratitis capitata (Diptera: Tephritidae) in Argentina: Releases of Diachasmimorpha longicaudata (Hymenoptera: Braconidae) in Fruit-Producing Semi-Arid Areas of San Juan

The Mediterranean fruit fly (Medfly), Ceratitis capitata (Wiedemann) is one of the major pests of fruit crops in Argentina and it is a phytosanitary barrier to the export of fresh fruits. In the Province of San Juan, located in the central-eastern region of Argentina known as Cuyo, control strategies against Medfly in fruit-producing irrigated-valleys have been implemented by the National Fruit Fly Control and Eradication Program (ProCEM) jointly with the provincial government and the producers. This program uses an area-wide integrated pest management approach that includes the use of environment-friendly strategies to suppress or eradicate Medfly, such as the useof the sterile insect technique and the application of new-generation bait sprays, and more recently the release of the Indo-Pacific parasitoid Diachasmimorpha longicaudata (Ashmead). This exotic larval-prepupal endoparasitoid is being mass-reared on larvae of Vienna 8 TSL C. capitata strain at the BioPlanta San Juan facility. In this respect, the objective of this study was to assess the effectiveness of laboratory-reared D. longicaudata females in order to find and successfully parasitize Medfly larvae in different host fruit species once released under semi-arid environmental conditions in ecologically isolated fruit-growing valleys of San Juan. Ground releases were used to disperse parasitoids in 6 fruit-producing valleys. In total, 40,000 adult parasitoids were released at places with various Medfly host plants bearing fruits and in which no insecticides were regularly applied, such as backyards and small orchards. 119 D. longicaudata adults were recovered from 6 Medfly-infested fruit species that were collected in 5 release sites (Pocito, Zonda, Santa Lucía, Caucete, and Rivadavia). The highest number of parasitoids was recovered from fig, followed by grape, rose, orange, tangerine, and persimmon. Data provided from this study open up the possibility of implementing a parasitoid mass-release program in San Juan.Fil: Suárez, Lorena. Provincia de San Juan.

Análise do sistema, desenho do projecto e criação de uma base de dados relacional para a gestão da informação de uma ganaderia de toiros de lide

Análise exaustiva de toda a informação que é tratada na gestão de uma ganaderia de toiros de lide. Esta informação foi organizada em grupos (entidades/tabelas) de modo a poder conceber o desenho do fluxo dessa informação entre as várias entidades. Após o desenho global do projecto da gestão da informação de uma ganadeira de toiros de lide, foi desenvolvida uma aplicação, utilizando o Microsoft Access, que permite realizar essa mesma gestão. Esta aplicação permite acompanhar os animais da ganaderia, desde o seu nascimento até à morte, mantendo a informação de todo o seu percurso. Por fim, a aplicação permite que toda a informação de cada animal fique guardada, de modo a que todo o histórico da ganaderia seja acessível através da aplicação. O objectivo principal desta aplicação é facilitar, ao gestor, a escolha dos reprodutores de modo a alcançar a bravura desejada para os animais da sua ganaderia; permitir aceder à informação de uma maneira mais rápida e sistemática que na gestão pré-informatizada; obter a documentação, em suporte físico, mais organizada, tornando a sua consulta posterior mais fácil e clara

Adaptive capabilities, pathdependence and institutional change: insights from an empirical work on rural producers organizations

During the last twenty years, the evolution of public policies in Southern countries has been characterized by the implementation of liberalization processes, which can be analyzed through Douglass North's institutional change approach. In Costa Rica, liberalization processes, that mainly consisted in State withdrawal and frontiers' opening, led to private actors' empowering and induced different strategic behaviors among rural producers' organizations. In this paper, we carry out a comparative study of four farm sectors (coffee, milk, black bean and pineapple), based on a dynamic approach of behaviors in relation with institutional changes occuring during the liberalization process. We highlight organizations'capacities to adapt and participate to institutional changes by (i) implementing economical activities and (ii) acting upon public policies. We underline the fact that rural producers organizations play a key role in farm sectors' efficiency and sustainability, permiting both producers' market insertion (acces to domestic and world markets) and political participation (obtention of public suppports). We show that the conditions for success of collective action depend on organization's mental models and organization's resources endowment, and are in line with pathdependent logic. More generally, our study allows us to get a better understanding of institutional and economic dynamics. (Résumé d'auteur

Public Policies Still Alive Within a Liberalized Environment: Insights From Costa Rica

We carry out a comparative study of four farm sectors in Costa Rica, based on a dynamic analysis of behaviors regarding institutional changes occurring during the liberalization process. We highlight organizations' capacities to adapt and contribute to institutional changes by implementing economical activities and participating to policy making processes. We show that organizations play a key role in the regulation of farm sectors, and that their success depends on the institutional and organizational thickness they have contributed to create in each sector and responds to a path-dependent logic. ...French Abstract : Nous menons une étude comparative de quatre filières agricoles au Costa Rica, qui repose sur une analyse dynamique des comportements des acteurs des filières au regard des changements institutionnels liés à la libéralisation économique. Les organisations de producteurs agricoles, qui jouent un rôle clé dans la régulation des filières, ont opté pour des comportements stratégiques différents. Nous mettons en évidence les capacités de ces organisations à s'adapter mais également à contribuer aux changements institutionnels en mettant en place des activités technico-économiques de transformation et commercialisation et en participant aux processus de négociation des politiques. Nous montrons que leur succès dépend de la densité institutionnelle et organisationnelle qu'elles ont contribué à créer au sein de chaque filière et s'inscrit dans une logique de dépendance au sentier.ORGANIZATIONS; POLICIES; INSTITUTIONAL CHANGE; PATHDEPENDENCY; ORGANISATIONS; POLITIQUES; CHANGEMENT INSTITUTIONNEL; DEPENDANCE AU SENTIER

Inversión Pública de Nicaragua : Inversión pública en contrucción vial por el Ministerio de Transporte e Infraestructura (NTI), en el periodo 2013-2016

En el presente trabajo se muestra un estudio acerca de la gestión que ha realizado el Ministerio de Transporte e Infraestructura en el periodo 2013-2016, mediante los datos encontrados acerca de los proyectos de infraestructura vial, en el cual se conocerán cuáles han sido las regiones que han tenido una mayor inversión y las que han tenido un mayor número de proyectos. También se presentan los tipos de proyectos que se realizan en las distintas regiones del país. Se exponen los principales proyectos que se han realizado a lo largo del periodo comprendido en las tres regiones del país, el costo de cada uno de estos proyectos y la proveniencia de los fondos para su realización. Finalmente, después de la ejecución de todos los proyectos en infraestructura vial que realizo el Ministerio de Transporte e Infraestructura, se elaboraron análisis comparativos en el número de trabajadores y de kilómetros pavimentados por región, comparando año tras año, con el objetivo de identificar las mejoras infraestructurales entre un año y otro para ello se elaboró un análisis socio-económico anual de todas las regiones del país
