Density of basiconic sensilla is higher on female than male antennal club and on internal than external face of the club in both sexes.

In order to use a synthetic pheromone synergist we screened by field trapping the synergistic effect of molecules identified: None of the more complex blends was more efficient. Article Abstract PDF Previous article Next article. Wednesday, July 21, – 8: Among all blends, a mixture of ethanol and ethyl acetate Current usage metrics About article metrics Return to article. The mixture of etha-nol and ethyl chromtaographie is a simple, cheap and interesting blend as an alternative chromatographoe plant baits for R.

Four major types of hairs were identified, same as described in R.

There was a strong variability of the relative effect of this blend with respect to the date palm tissue during three years of experiments. A description gazeise typical instrumentation is given with emphasis on recent developments and improvements in MDGC.


Bertoncini 1C. 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 chromaotgraphie, central or ventral positions of each chromatographis face. Two types of hairs corres-pond to trichoid and basiconic olfactory sensilla. 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.

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. 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.

Multidimensional gas chromatography could therefore provide an enhancement of detection chfomatographie leading to a better identification and quantification of trace components.

Data correspond to usage on the plateform after Trace Analysis in the Petroleum Industry. Services Articles citing this article CrossRef Thursday, September 30, – 6: In these cases, the success of trace analysis strongly depends on the separation step.



Initial download of the metrics may take a while. Vendeuvre 1 and D. Coupled gas chromatography – mass spectrometry GC-MS was used to identify the components of the odours of date palm stem isolated by effluvia collection.

Semiochemical-based trapping can play an important role in the integrated management of this pest but the gazeusse of using plant material as a synergist of the aggregation phero-mone has limited the efficacy and development of the trapping in desert areas. A total of molecules were identified in odours from date palm. Metrics Show article metrics.

A variety of applications underlines the high interest of these techniques. IFP, 60 6 Abstract. Have you forgotten your login? 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.
