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...

Characterization and analysis of waxes by differential thermal analysis National Institute of Agronomic Research
Currel, B.R.; Robinson, B..
The characterization of waxes by differential thermal analysis is described. An endothermic peak at 475-480° is characteristic of microcrystalline and polyethylene waxes, and measurement of its area provides a method for the estimation of these waxes in mixtures.

Characterization, quantification, isolation and conservation of N2-fixing BGA from rice soils IRD
Santiago Ardales, S.; Roger, Pierre-Armand.
This paper summarizes results concerning : 1) the development of a methodology to estimate quantitatively and qualitatively populations of BGA in rice soils, 2) the application of these methods to the study of 102 samples of wetland rice soils from several rice growing countries, and 3) the conservation of strains isolated during these studies.

Essais de lutte chimique contre les foreurs du maïs en zone des savanes de Côte d'Ivoire IRD
Moyal, Pascal.
Des essais de protection chimique contre les foreurs du maïs effectués dans le centre de la Côte d'Ivoire ont permis de quantifier les pertes de rendement dues à ces insectes sur le cycle de culture semé en juin. Ces pertes vont de 54 à 98 % dans les essais réalisés. Cinq foreurs sont en cause : trois s'attaquent principalement aux tiges : #Eldana saccharina$ Walker (#Lepidoptera$, #Pyralidae$), #Busseola fusca$ (Fuller) (#Lepidoptera$, #Noctuidae$) et #Sesamia calamistis$ Hampson (#Lepidoptera$, #Noctuidae$) ; deux s'attaquent exclusivement à l'épi : #Mussidia nigrivenella$ Ragonot (#Lepidoptera$, #Pyralidae$) et #Cryptophlebia leucotreta$ (Meyrick) (#Lepidoptera$, #Tortricidae$). Il est possible d'obtenir des gains de rendement économiquement...

Improvement of calibration models using two successive orthogonal projection methods. Application to quantification of wine mannoproteins Inra
Boulet, J.C.; Doco, T.; Roger, J.M..
The improvement of calibration in infrared spectrometry requires a reduction of the effect of interference, that is to say the chemical or physical factors that disturb the spectrum and reduce measurement accuracy. We propose a methodology based on two successive orthogonal projections (SOP) that makes it possible to take into account the influence of the other identified and characterised chemical compounds. A first OSC or EPO projection was based on the pure spectra of the compounds in the solution. A second projection (OSC method) was performed on the calibration set obtained after the first projection. These two projections minimise respectively the identified chemical influence factors and the unidentified influence factors. Application on wine...

Quantification des populations de Sitona lineatus L. et de leurs attaques sur pois proteagineux (Pisum sativum L.) Inra
Cantot, P..
Le sitone du pois est très fréquent en France dans les cultures de pois protéagineux. Grâce à des enquêtes et relevés effectués dans différents départements, on a défini une méthode simple de prélèvement des adultes par piégeage à l’aide de boîtes posées sur le sol et des larves par prélèvement de terre. Une échelle de notation de 0 à 3 des dégâts occasionnés par les adultes hivernants sur les folioles de la première feuille des plantes de pois est proposée. Cette notation est effectivement corrélée au nombre d’adultes présents dans le champ. La notation permet aussi de prévoir les effectifs larvaires ultérieurs. Les populations larvaires peuvent détruire 90 p. 100 de la nodulation du pois lorsque leurs effectifs atteignent une douzaine de larves par...
