The Ideal

The parasitoid in eggs of Trichogramma genre is the most studied in the world, being bred widely and used for flooding releases. This study aimed to evaluate the capacity for parasitism of Trichogramma galloi Zucchi, 1988 (Hymenoptera: Trichogrammatidae) in Neoleucinodes elegantalis (Guenée) (Lepidoptera: Crambidae) eggs at different temperatures. The experiment was developed at the Nucleus for Scientific and Technological Development in Phytosanitary Management (NUDEMAFI) in which the daily and accumulated biological parameters were assessed, as well as total parasitized eggs by female, sexual ratio (number of females/number of males + females), viability of the eggs (number of eggs with orifice/number of parasitized eggs x 100) and number of individuals per egg at temperatures 18, 21, 24, 27 and 30ºC. The eggs of the fruit borer were offered daily to each T. galloi female at each temperature until the death of the parasitoid could be verified. The larger number of parasitized eggs was found in the first 24 h, at temperatures 24 and 27ºC with 17 parasitized eggs. The accumulated parasitism in N. elegantalis eggs reached 80% of total parasitized eggs for each thermal range (18, 21, 24, 27 and 30ºC) on the 2nd, 3rd, 3rd, 1st and 2nd days respectively. The ideal parasitism conditions for this lineage vary between 24 and 27°C. Therefore, it is concluded that the studied T. galloi lineage has adequate biological parameters in N. elegantalis eggs, demonstrating promise in phytosanitary management of this pest.

The Ideal

Nanotechnology represents, in part, a technological revolution in the sense that it allows highly innovative applications of various areas of the physical and life sciences. The development of nanotechnology and nanoscience, however, intensifies challenges to the traditional understanding of how to pursue scientific and technological knowledge. Science (in its broad meaning) can no longer be construed simply as the ideal of the quest for truth (i.e., “pure science”). Science, through its technological applications, has become the source of economic power and, by extension, political power. Science, with its political implications, has entered what John Ziman calls the era of “post-academic science.”In this paper, I argue that nanotechnology is a cardinal exemplar of this politicization, that is, the convergence of science, technology, politics, and economics for social and governmental purposes. At the same time, I assert that this new scientific ethos offers the possibility of a better integration of ethical and philosophical reflections at the core of scientific and technological development.

The tomato is a crop of great importance for Brazilian agriculture. Among the most damaging pests, the small tomato borer, Neoleucinodes elegantalis Guenée (Lepidoptera: Crambiadae) has caused great losses, since they directly reach the fruits to be commercialized, being used for its handling a large volume of insecticides. In this way, the use of alternative techniques that help in the management of this pest becomes of great importance. Among them, the use of the egg parasitoid Trichogramma spp. has been promising. Thus, the present study aimed to evaluate the performance of Trichogramma species and/or strains in N. elegantalis by selection of strains. The selection was made based on four lineages maintained in the Nucleus of Scientific and Technological Development in Phytosanitary Management of Pests (NUDEMAFI), being three strains of the species T. pretiosum and one of T. galloi species. The parameters evaluated were percentage of parasitized eggs, egg viability, number of individuals per eggs, sex ratio and number of Trichogramma spp. to be released. The T. galloi (T. g1) showed the best parameters for selection of the strain. Estimating the optimal number of T. g1 in eggs of small-fruit-borer was 82 individuals per egg parasitoid. Therefore, this strain was selected for the management of the small tomato-borer, whose eggs presented favorable physicochemical characteristics for the development of the parasitoid.

Scientific And Technological Development

Throughout history the development of the countries has been generated mainly by the impulse in two complementary axes: Science and Technology, and Trade. At present we are experiencing an exponential scientific and technological development and the Economy in all its fronts is driven by the intensive application of technology. According to these considerations, this research tries to expose the development of Innovation Management as a transversal mechanism to promote the different socioeconomic areas and especially those supported by engineering. To this end, use will be made of Technology Watch in order to identify the advances of the main research centres related to innovation in the world. Next, there will be an evaluation of the main models of Innovation Management and related methodologies that expose some of the existing Innovation Observatories in the world to finally make a proposal for Innovation Management applicable to the reality of Peru, so that it can be taken into consideration by stakeholders (Government, Academy, Business and Civil Society) committed to Innovation Management in the country

The author presents a vision of the mainstream vectors of global development against the backdrop of the “Grand Challenges” of the 21st century. He formulates optimal ways for Russia and Africa to interact in order to achieve the goals set by the UN Third International Conference on Financing for Development. The author proposes a RUSAFRICA project, which combines a dual goal of boosting economic, social and technological development of both Russia and Africa. The project envisages an integrated cooperative approach to mutually significant economic, technological and infrastructural requirements and capacities while prioritizing the human development aspect. Innovative approaches to mutual cooperation shale open ways to promoting Russian technologies and innovative products to new markets, generating growth of income from exports of high technology products and services with the aim to enhance Russia’s influence and competitive strengths, in accordance with the Scientific and Technological Development Strategy of the Russian Federation.
