ORBi Open Repository and Bibliography (260.650 recursos)

In may 2007, the ULg's Administrative Board (joined in June 2007 by the FUSAGx) decided to create an institutional repository and defined a strong institutional self-archiving policy to increase the visibility, accessibility and impact of the University's publications (Board's decision). This decision led to the official launch, in November 2008, of the ORBi platform including both the Academic Bibliography and the Institutional Repository of the Wallonia-Europe University Academy.

  4. Biofilm fermentation for the production of insect pathogenic fungi

    Bawin, Thomas; Francis, Frédéric; Delvigne, Frank
    Currently, integrated pest management that aims to reduce the use of synthetic insecticides by considering all appropriate alternative methods, is promoted. In that context, insect pathogenic fungi could be developed as biopesticides in two ways: spores but also metabolites that are recognized as virulence factors. Targeting adequate fermentation method is an important requirement to obtain fungal products (i.e. spores, enzymes and metabolites) of biotechnological interest. The 'Microbial Processes and Interactions' laboratory has developed an innovative fermentation technology (referred to as ‘biofilm fermentation’) involving the growth of fungal biomass on inert supports that are immersed in a liquid nutrient medium. Confining fungal...

  5. Impacts of entomopathogenic fungi on biology and behaviour of the invasive Brown Marmorated Stink Bug (Hemiptera, Pentatomidae)

    Fingu Mabola, Junior Corneille; Serteyn, Laurent; Bawin, Thomas; Delvigne, Frank; Francis, Frédéric
    Halyomorpha halys St˚al (Hemiptera, Pentatomidae) is an invasive stink bug coming from Eastern Asia. Besides causing important yields losses in orchards, crop and vegetable fields, it overwinters inside houses as agglomerates of dozens. In Europe, this Brown Marmorated Stink Bug (BMSB) was accidentally introduced in Switzerland in 2007 and has been later observed in surrounding countries (France, Italy, Germany). Based on the current US situation, we can reasonably fear that BMSB will have colonized most of Europe countries in less than a decade. If we already discern a few fungus strains that are efficient against BMSB, very little is known about their actual impact on the insect...

  7. Can tropical basil be integrated in vegetable crop pest management?

    Yarou, Boni Barthélémy; Verheggen, François; Heuskin, Stéphanie; Lognay, Georges; Francis, Frédéric
    To address human and environmental health issues related to the use of synthetic pesticides, it is important to explore other ecological pest management approaches. Within this context, a study was conducted to evaluate the toxic and repellent effect of Ocimum gratissimum L. (Lamiaceae) on Myzus persicae S. (Aphididae). The toxicity of O. gratissimum essential oil (EO) was evaluated on M. persicae comparing 3 concentrations (0.001%; 0.01% and 0.1%) to a control (15% sucrose). Mortality rate and fecundity were assessed for each concentration. The observations were made daily, for 4 days, on 12 replicates per treatment. To test the repellent effect...

  9. Global changes, human activities and (re-) emerging of mosquito-borne pathogens: diversity, ecology and control of potential vectors

    Boukraa, Slimane
    Worldwide, mosquitoes (Diptera: Culicidae) are known as potential vectors of pathogens that cause infectious diseases, affecting both humans and animals, such as malaria, dengue, chikungunya, West Nile fever and dirofilariasis. In terms of morbidity and mortality, mosquitoes are considered as the most dangerous animals confronting mankind. Indeed, over three billion people live at risk of becoming infected by a mosquito-borne disease. Focus on mosquitoes has greatly increased not only in the tropic areas but also in the Palearctic region like Europe and Mediterranean areas. Researches on re-emerging vector-borne diseases are become a major issue in human and animal health worldwide,...

  13. Croissance allométrique chez Brachionus falcatus Zacharias : (Totifère, Brachionidae)

    Magis, Noël
    a) Ce travail consiste en une biométrique de six populations de Brachionus falcatus Zacharias (femelles parthénogénétiques) originaires du lac de Koni, tributaire de la Lufira (Haut-Katanga). -- b) Les techniques biométriques, complétées par la définition d'un critère de la maturité sexuelle, permettent d'isoler dans ces populations, formées d'individus d'âge inconnu, des spécimens en période d'immaturité et d'autres en période de fécondité. La précision de ces méthodes est pourtant insuffisante pour dégager l'existence éventuelle d'une phase sénile dans le cycle vital de cette espèce. -- c) Les individus immatures et féconds ne diffèrent pas uniquement par leur taille mais aussi par...

  17. Sur les besoins nutritifs du Gnathocerus cornutus F. : (Coléoptère, Ténébrionide) : Recherche de l'optimum glucidique et de l'optimum protidique dansun régime alimentaire artificiel

    Leclercq, Jean; Magis, Noël; Rey, Cécile
    1) De jeunes larves et Gnathocerus cornutus F. ont été élevées à 30°C, dans de la farine de froment non blutée, dans la levure sèche, et dans cinq milieux comportant chacun 10% de levure et respectivement 90, 75, 45, 15 ou 0% de caséine et 0, 15, 45, 75, ou 90% de glucose. -- 2) Les milieux naturels, surtout la farine de froment, furent les plus favorables si on considère la mortalité, la croissance pondérale et la durée du développement. C'est, en outre, dans la farine de froment qu'on a observé la moyenne la plus élevée pour le poids nymphal....
