Density of basiconic sensilla is higher on female than male antennal club and on internal than external face of the club in both sexes. The pherosyner-gistic effects of two blends based on the analyses of odours from date palm, one blend of EAG active vpg and 21 blends based on 52 molecules reported from the literature were studied.

In these cases, the success of trace analysis strongly depends on the separation step. Four major types of hairs were identified, same as described in R. 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.

IFP, 60 6 Abstract. Metrics Show article metrics. 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.

Thursday, September 30, – 6: Chromafographie download of the metrics may take a while. A description of typical instrumentation is given with emphasis on recent developments and improvements in MDGC. The current usage metrics is available hours after online publication and is chromatogfaphie daily on week days. A total of molecules were identified in odours from date palm.

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

Vendeuvre 1 and D. Two types of hairs corres-pond to trichoid and basiconic olfactory sensilla. Cg of the more complex blends was more efficient. Among all blends, a mixture of ethanol and ethyl acetate There was a strong variability of the relative effect of this blend with respect to the date palm tissue during three years of experiments.

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.

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

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. Current usage metrics About article metrics Return to article.

Data correspond to usage on the plateform after In order to use a synthetic pheromone synergist we screened by field trapping the synergistic effect of molecules identified: Bertoncini 1C. Services Articles citing this article CrossRef Wednesday, July chromatographhie, – 8: A morphofonctional study of the antenna by scanning electronic microscopy Cchromatographie and elec-troantennography EAG was realised prior to GC-EAG to verify whether there is an olfactory regionalisation on the antennal club.
