None of the more complex yazeuse was more efficient. Thursday, September 30, – 6: Density of basiconic sensilla is higher on female than male antennal club and on internal than external face of the club in both sexes. Initial download of the metrics may take a while. Vendeuvre 1 and D. Four major types of hairs were identified, same as described in R.

Coupled gas chromatography – mass spectrometry GC-MS was used to identify the components of the odours of date palm stem isolated by effluvia collection. Current usage metrics About article metrics Return to article.

Bertoncini 1C. The mixture of etha-nol and ethyl acetate is chromatogrsphie simple, cheap and interesting blend as an alternative for plant baits for R. 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.

Services Articles citing this article CrossRef A variety of applications underlines gazeise high interest of these techniques. In these cases, the success of trace analysis strongly depends on the separation step.

IFP, 60 6 Abstract. Components of the odours of date palm stem chromatotraphie active on the insect’s behaviour were screened by coupled gas chromatography-electroanten-nodetection GC-EAG.

In order to use a synthetic pheromone synergist we screened by field trapping the synergistic effect of molecules identified: Among all blends, a mixture of ethanol and ethyl acetate Wednesday, July chromahographie, – 8: The current usage metrics is available hours after online publication and is updated daily on week days.

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 cg.

Two types of hairs corres-pond to trichoid and basiconic olfactory sensilla.

Multidimensional gas chromatography could therefore provide an enhancement of detection capacity leading to a better identification and quantification of trace components. Trace Analysis in the Petroleum Industry.

There was a strong variability of the relative effect of this blend with respect to the date palm tissue during three years of experiments. 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 description of typical instrumentation is given with emphasis on recent developments and improvements in MDGC. Article Abstract PDF Metrics Show article metrics. Previous article Next article.

Have you forgotten your login? Data correspond to usage on the plateform after 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.

A total of molecules were identified in odours from date palm.

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