En 2010, la création des facultés d’architecture au sein des universités belges à ajouter à leur mission unique d’enseignement les missions de recherche et de service à la communauté. A Liège, le changement institutionnel connut une difficulté accrue liée à la fusion de deux institutions jusque-là « concurrentes ». Un lien les unissait cependant : conserver la maîtrise du projet pédagogique spécifique à l’enseignement de l’architecture, une formation visant la conception du projet architectural et sa méthodologie grâce à une pédagogie par projet. En 2011, un groupe d’enseignants praticiens-réflexifs (Schön, 1987) s’est formé pour analyser, questionner le dispositif de formation et le plan d’études résultant des mécanismes administratifs de création de la faculté. Un premier constat de carence est rapidement apparu : l’inexistence d’un socle pédagogique commun définissant les visées de la formation dans un cadre professionnalisant et permettant d’assurer un alignement pédagogique cohérent entre contenus, méthodes et évaluations. Le groupe a dès lors décidé de s’atteler à la construction d’un référentiel de compétences (Tardif, Fortier, & Préfontaine, 2006) comme pierre angulaire de toute réflexion. En juin 2013, le référentiel a été validé par le conseil de faculté. Quels enjeux (politiques, pédagogiques) ont été identifiés ? Comment les liens entre identité professionnelle, formation et profil de compétences professionnelles ont-ils été établis ? (Beckers, 2007). Quelle place occupe ou devrait occuper l’enseignement du projet par le projet dans l’université ? Comment intégrer, en parallèle à une conception « traditionnelle » de pratique architecturale, les dimensions de la recherche et du questionnement théorique ? En quoi cette recherche-action a-t-elle été pour les enseignants d’atelier un véritable levier réflexif ? Ce retour d’expérience permettra de tirer les premières conclusions critiques liées à l’adoption du référentiel et d’identifier les futures actions et/ou réflexions qui s’engageront à court, moyen et long terme.

Research on the defensive chemistry of insects during the last decade is reviewed, with special emphasis on non-volatile compounds. The isolation and structure determination of defensive chemicals, of glandular and non-glandular origins, are first discussed, followed by an overview of the synthesis and biological/pharmacological activities of some of them. Biosynthesis has been largely omitted since this topic has been addressed in a recent review. During the period covered, beetles (e.g., coccinellids and chrysomelids) and ants have undoubtedly been the most prolific producers of repellent and/or toxic compounds. This survey also shows that alkaloids are the most frequently encountered defensive compounds in insects. [less ▲]

Many mosquito (Diptera: Culicidae) species are vectors responsible for the transmission of infectious diseases of medical and veterinary importance. Risk for infection considerably increased during the last decades due to climate changes and increasing global trade. Vector control is essential for public health management. Integrated pest management is now promoted due to harmful side effects of the chemical insecticides classically used for mosquito control and insect resistance development. This PhD thesis takes part in the selection process of insect pathogenic fungi. Three biological models (Aspergillus clavatus Desmazieres, Aspergillus flavus Link, and Metarhizium anisopliae (Metschnikoff) Sorokin) were selected and investigated regarding their spore insecticidal activity, mode of action, and selectivity. Throughout this scheme, the use of agricultural materials and derivatives in fermentation processes was emphasized. Production methods and insecticidal potential of the fungi were first investigated. On the one hand, the two Aspergillus species were compared to M. anisopliae regarding their spore production when cultured on agro-industrial substrates (white rice and wheat bran) and their insecticidal effect on larvae of the southern house mosquito, Culex quinquefasciatus Say. Our results showed that both substrates are suitable to culture the three insect pathogenic fungal species; but wheat bran-based media increased from 3 to 7-fold the spore yields in solid-state compared to white rice-based media. Also, insect pathogenic Aspergillus species were suggested to yield in similar spore levels in such conditions (in a range of 10^9 spores per g of substrate) and be as virulent against mosquito larvae compared to M. anisopliae. On the other hand, a bioreactor design intended to support large-scale production on agricultural materials by combining the technological advantages of submerged and solid-state fermentations was implemented using A. clavatus. This system allowed facility in recuperation and purification of spores (confined on a packed solid substrate) that retained virulence against mosquito larvae; but also metabolites (contained in a circulating liquid medium) that showed insecticidal effect. The mechanisms responsible for the insecticidal effects of the spores, and their selectivity were then investigated. On the one hand, the invasion routes of A. clavatus spores on mosquito larvae were investigated by light and electron microscopy. Histological observations suggest that toxins secreted by active germinating spores of A. clavatus in the digestive tract altered the larval tissues, leading to necrosis and causing larval death. Fungal proliferation and sporulation then occurred during a saprophytic phase. Such action mode also probably occurred in the case of the two other species. On the other hand, the insecticidal activity of the fungi was assessed against the pea aphid, Acyrthosiphon pisum Linnaeus. Adult A. pisum aphids were susceptible (increased mortality and decreased reproductive potential) to the three fungal species. As a consequence, these fungi would probably be able to infect a broad spectrum of insect hosts (whatever terrestrial or aquatic) once released in the environment. The implications of the results for mosquito control and application strategies are finally discussed, and perspectives for future works proposed. [less ▲]

The inventory of pests occurring on Dacryodes edulis (Burseraceae) was carried out in rural areas in Gabon during 2009 and 2010. Yellow traps and visual observations were used to record weekly pests during the tree flowering stage, in five villages. Catches from yellow traps rose to 7,296 and 1,722 insect pests in 2009 and 2010, respectively, whereas records from visual observations corresponded to 1,812 and 171 insect pests in 2009 and 2010, respectively. During both years, abundance from traps and visual monitoring was significantly different between sampling sites (p<0.05). The difference in pests’ diversity between sampling sites was not significant (p>0.05) according to traps, but significant (p≤0.04) according to visual observations in 2010. Mecocorynus loripes Chevrolat (Coleoptera: Cucurlionidae) attacked the stem of D. edulis, while Oligotrophus sp. (Diptera: Cecidomyiidae), Pseudophacopteron serrifer Malenovsky and Burckhardt (Hemiptera: Phacopteronidae), and Selenothrips rubrocinctus Giard (Thysanopera: Thripidae) attacked leaves. Pseudonoorda edulis Maes and Poligui (Lepidoptera: Crambidae) and Lobesia aeolopa Meyrick (Lepidoptera: Tortricidae) infested fruits and inflorescences, respectively. These insects are specifically linked to plant patterns, and their identification provided the first basic information for developing suitable strategies to control pests of D. edulis in Gabon, as well as in neighboring central African countries.
