(3Z,6Z,8E)-3,6,8-dodecatrien-1-ol : Sex pheromone in a higher fungus-growing termite, Pseudacanthotermes spiniger (Isoptera, Macrotermitinae) Inra
Bordereau, C.; Robert, A.; Bonnard, O.; Le Quere, J.L..
The female sex pheromone of the fungus-growing termitePseudacanthotermes spiniger (Termitidae, Macrotermitinae) was isolated from sternal glands of alates. The compound inducing attraction and excitation in males was identified as the (3Z,6Z,8E)-3,6,8-dodecatrien-1-ol by GC-MS, microhydrogenation, GC-FTIR, and NMR. This unsaturated alcohol is present in both sexes but in much higher quantities in females than in males (about 10 times). The hypothesis is suggested that this alcohol, which is detected at extremely low concentrations by the workers ofP. spiniger, may be used either as a trail-following pheromone or a sex pheromone according to concentrations and to target castes. The presence of this alcohol in Macrotermitinae reinforces the idea of a...

A locally congenic backcross design in pig: a new regional fine QTL mapping approach miming congenic strains used in mouse Inra
Riquet, J.; Gilbert, H.; Servin, B.; Sanchez, M.P.; Iannuccelli, N.; Billon, Y.; Bidanel, J.P.; Milan, D..
Background: In previous studies, a major QTL affecting fatness and growth has been mapped to pig chromosome1q (SSC1q) using Large White - Meishan intercrosses. A higher fat depth and a larger growth rate have beenreported for the allele of MS origin. Additionally the LW allele showed partial dominance effects over the MS allelefor both traits. In order to refine the QTL mapping interval, advanced backcross generations were produced.Recombinant heterozygous sires were mated to LW sows in order to progeny test the sire segregation of the QTLand refine the QTL localisation. However due to the partial dominance of the LW allele, BC scheme using LW asthe receiving population was not optimal.Results: To overcome the difficulties related to the dominance of the...

A new attempt at discrimination between Quercus petraea and Quercus robur based on wood anatomy Inra
Feuillat, F.; Dupouey, J.L.; Sciama, D.; Keller, R..
La variabilité inter-spécifique de l’anatomie du bois des deux principaux chênes de la forêt européenne (Quercus robur L. et Quercus petraea (Matt.) Liebl.) est encore paradoxalement peu connue. Pourtant, l’anatomie conditionne pour une large part les propriétés technologiques du bois et le fonctionnement écophysiologique des arbres. La possibilité d’identifier l’espèce à partir d’échantillons de bois offrirait aussi une large gamme d’applications. Quatorze peuplements mélangés de chênes pédonculé et sessile de la forêt de Cîteaux (Bourgogne) ont été échantillonnés (58 chênes au total). Par analyse d’images radiographiques de carottes de sondage, on a caractérisé la forme, la taille et la proportion des différents tissus (gros vaisseaux, fibres, parenchyme...

Acetylcholine in the larval food, honey, and stored pollen of a stingless bee, Melipona quadrifasciata National Institute of Agronomic Research
Welsh, John H.; Nogueira-Neto, Paulo; Jaeger, Celso P.; Ancona Lopez, Ana Amelia.
1) Using several methods, the larval food of Melipona quadrifasciata was found to contain amounts of acetylcholine estimated to range between O. 5 and 2.0 mg. equivalents of acetylcholine chloride per gram of larval food. Similar amounts have been reported for the larval food of the honey, bee, Apis mellifera. 2) The larval food of M. quadrifasciata was also found to contain a large amount of choline and an unidentified substance that was soluble in ethanol, gave a blue fluorescence, reacted with Dragendorf's reagent, and had a weak acetylcholine-like action. In one sample of larval food, a substance with the properties of glycine betaine was also found. 3) Samples of stored pollen were also found to contain acetylcholine, choline and the unidentified...

Aetiology and ecology of a yam mosaic disease in Burkina Faso IRD
Goudou-Urbino, C.; Konate, G.; Quiot, J.B.; Dubern, Jean.
Yam virus diseases were surveyed for 3 years in Burkino Faso. Mosaic and green vein banding symptoms were observed on two species (#Dioscorea cayenensis rotundata$ and #Dioscorea alata$) in the south-west and southern aeras, and on the Pilimpikou yam cultivar in the central area. Using electron microscopy, ELISA and host range studies, it was found that plants were infected with a potyvirus similar to yam mosaic virus in host range, morphology and serology. This virus was not detected in the southern area but occurred at a low rate (13%) in the south-west and more frequently (71.5%) in the central aera. Healthy yam plants were exposed to natural infection for 5 months in these two areas and checked for virus contamination by ELISA. Tubers from markets were...

Alcaloïdes des Annonacées, 68 : alcaloïdes des feuilles de Guatteria ouregou IRD
Cortes, D.; Hocquemiller, R.; Leboeuf, M.; Cavé, A..
Des feuilles de #Guatteria ouregou$, Annonacée guyanaise, ont été isolés 22 alcaloïdes aporphiniques, dont 6 nouveaux, et appartiennent à des types structuraux originaux. Les résultats mettent en évidence une grande différence dans la composition en alcaloïdes entre les différents organes de la plante, dont la signification chimiotaxonomique est ici discutée.
