In order to use a synthetic pheromone synergist we screened by field trapping the synergistic effect of molecules identified: Wednesday, July 21, – 8: A description of typical instrumentation is given with emphasis on chromatogarphie developments and improvements in MDGC. The pherosyner-gistic effects of two blends based on the analyses of odours from date palm, one blend of EAG active molecules and 21 blends based on 52 molecules reported from the literature were studied.

A total of molecules were identified in odours from date palm. The mixture of etha-nol chromatographiee ethyl acetate is a simple, cheap and interesting blend as an alternative for plant baits for R.

Services Articles citing this article CrossRef There was a strong variability of the relative effect of this blend with respect to the date palm tissue during three years of experiments. Trace Analysis in the Petroleum Industry. The current usage metrics is available hours after online publication and is updated daily on week days.


Components of the odours of date palm stem putatively active on the insect’s behaviour were screened by coupled gas chromatography-electroanten-nodetection GC-EAG. Previous article Next article.

Semiochemical-based trapping can play an important role in the integrated management of this pest but the necessity of using plant material as a synergist of the aggregation phero-mone has limited the efficacy and development of the trapping in desert areas.

Two types of hairs corres-pond to trichoid and basiconic olfactory sensilla. Metrics Show article metrics.

Four major types of hairs were identified, same as described in R. A morphofonctional study of the antenna by scanning electronic microscopy SEM and elec-troantennography EAG was realised prior to GC-EAG to verify whether there is an olfactory regionalisation on the antennal club. In these cases, the success of trace analysis strongly depends on the separation step. A variety of applications underlines the high interest of these techniques. IFP, 60 6 Abstract. None of the more complex blends was more efficient.

Thursday, September 30, – 6: This paper aims to point out the interest and the advantages of multidimensional gas chromatography MDGC for performing trace analysis in complex organic mixtures such as hydrocarbon mixtures, petroleum or oil samples, and typical feeds and products from refinery or petrochemical processes.


Data correspond to usage on the plateform after Among all blends, a mixture of ethanol and ethyl acetate Article Abstract PDF Initial download of the metrics may take a while. Density of basiconic sensilla is higher on female than male antennal club and on internal than external face of the club in both sexes. EAG amplitudes to six molecules were higher when the recording electrode was connected onto the internal compared to the external face but the same response profile was obtained on dorsal, central or ventral positions of each club face.

Bertoncini 1C. Coupled gas chromatography – mass spectrometry GC-MS was used to identify the components of the odours of date palm stem isolated by effluvia collection. Multidimensional gas chromatography could therefore provide an enhancement of detection capacity leading to a better identification and quantification of trace components. Vendeuvre 1 and D.
