Acarofauna em cultivo de pinhão-manso e plantas espontâneas associadas

O objetivo deste trabalho foi identificar ácaros na cultura de pinhão-manso e em espécies de plantas espontâneas associadas. Para isso, foram avaliadas a riqueza e a abundância de ácaros em plantas de pinhão-manso e em 14 espécies de plantas espontâneas associadas. As amostragens foram realizadas por meio de coletas mensais de folhas de plantas de pinhão-manso e de plantas espontâneas, nas entrelinhas do cultivo. Foram encontradas quatro espécies de ácaros predadores - Amblyseius tamatavensis, Paraphytoseius multidentatus, Typhlodromalus aripo e Typhlodromalus clavicus -, com potencial para uso no controle biológico de ácaros-praga na cultura do pinhão-manso, e duas importantes espécies de ácaros fitófagos - Brevipalpus phoenicis e Tarsonemus confusus - desconhecidas como praga da cultura. Entre as plantas espontâneas avaliadas, quatro espécies - Hyptis suaveolens, Peltaea riedelii, Urochloa mutica e Andropogon gayanus - abrigam grande riqueza e abundância de ácaros predadores, enquanto oito destacaram-se pela diversidade de ácaros fitófagos

Prospects for e+e- physics at Frascati between the phi and the psi

We present a detailed study, done in the framework of the INFN 2006 Roadmap, of the prospects for e+e- physics at the Frascati National Laboratories. The physics case for an e+e- collider running at high luminosity at the phi resonance energy and also reaching a maximum center of mass energy of 2.5 GeV is discussed, together with the specific aspects of a very high luminosity tau-charm factory. Subjects connected to Kaon decay physics are not discussed here, being part of another INFN Roadmap working group. The significance of the project and the impact on INFN are also discussed. All the documentation related to the activities of the working group can be found in http://www.roma1.infn.it/people/bini/roadmap.html.Comment: INFN Roadmap Report: 86 pages, 25 figures, 9 table

Sequence analysis of the ribosomal Internal Transcribed Spacers region in spider mites (Prostigmata: Tetranychidae) occurring in citrus orchards in Eastern Spain: use for species discrimination

Tetranychus urticae is a polyphagous mite which is an important pest of citrus worldwide. This mite can be found feeding on many plant species occurring in the citrus agrosystem moving from weeds to trees. Because field samples consist of a mixture of different Tetranychidae species, as a first step necessary to further implement population characterization of T. urticae, species-discriminating criteria based on molecular techniques are needed. In this study, the nucleotide variation of the Internal Transcribed Spacers (ITS) 1 and 2 and the intergenic 5.8S fragment of nuclear ribosomal DNA of T. urticae, T. turkestani, T. evansi, T. ludeni and P. citri, have been determined. Results demostrate that for these species, the rDNA ITS2 regions are much more conserved than the corresponding rDNA ITS1. The high homogeneity of the ITS2 sequence observed among the specimens of T. urticae obtained from the same eco-region makes this DNA-sequience an excellent tool for species discrimination. ITS sequences differentiate not only species but also specimens from different geographical origin. Furthemore, PCR-RFLP analysis of the ITS2 proved adequate for a quick screening of high numbers of field sample

Results demonstrate that for these species, the rDNA ITS2 regions are much more conserved than the corresponding rDNA ITS1. The high homogeneity of the ITS2 sequence observed among the specimens of T. urticae obtained from the same ecoregion makes this DNA sequence an excellent tool for species discrimination.

Palmprotect,an European applied research action devoted to palm borer pests

Palm Protect is an EU-funded program (2012-14) entitled: “Strategies for eradication and containment of invasive palm borers, Rhynchophorus ferrugineus and Paysandisia archon. The project aims at throwing light on aspects of the pest biology in Europe, which are unknown and preclude efficient control, validating new and reliable methods for detection and control, and implementing them into strategies for eradication of the palm borers both at the points of entry in the EU and in the infested areas. The project also aims at providing with an economic analysis to value palm services and management options and to disseminate the findings to the stakeholders. Palm Protect associates 12 research organisations, 1 SME, UK, France, Greece, Italy, Slovenia, Spain, Israel and Egypt. It is based on 6 actions: Management, Biology, Detection, Control, Economics and Dissemination. France contributes by INRA (Versailles et Sophia Antipolis) and CIRAD, which are particularly involved to provide new fundamentals about adult mobility, semiochemicals and parasitoids. The results will make it possible to improve European regulation and its efficacy from a consolidated scientific background in compliance with the standards in force for pest controlPalm Protect est un programme financé par l’UE (2012-14) intitulé ‘Stratégies pour l'éradication et le confinement des ravageurs invasifs des palmiers P. archon et R. ferrugineus’. Il a pour objectifs d’éclairer les éléments inconnus de la biologie en Europe de ces espèces qui limitent l’efficacité de la lutte, de valider des méthodes et des stratégies fiables et nouvelles pour leur détection, leur gestion et leur éradication tant aux points d’entrée que dans les zones contaminées. Palm Protect diffusera le fruit de ces travaux à tous les acteurs de la filière ‘palmiers’. Le programme associe 12 organismes de recherche, une PME, le Royaume-Uni, l’Espagne, la France, la Grèce, l’Italie, la Slovénie, Israël et L’Egypte. Il comprend 6 actions : Coordination, Biologie, Détection et surveillance, Lutte, Economie et Diffusion des acquis. La France contribue par l'INRA (Versailles et Sophia Antipolis) et le CIRAD, et s’implique fortement dans l’acquisition de connaissances nouvelles sur le déplacement des adultes, les médiateurs chimiques et les parasitoïdes. Les résultats serviront de base pour améliorer la réglementation européenne et son efficacité à partir de données scientifiques en application des règles générales en vigueur pour le contrôle des bio-agresseur
