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 these cases, the success of trace analysis strongly depends on the separation step. 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.

A description of typical instrumentation is given with emphasis on recent developments and improvements in MDGC. Vendeuvre 1 and D.

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.

In order to use a synthetic pheromone synergist we screened by field trapping the synergistic effect of molecules identified: 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.

Wednesday, July 21, – 8: There was a strong variability of the relative effect of this blend with respect to the date palm tissue during three years of experiments. 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.

Data correspond to usage on the plateform after Bertoncini 1C. The mixture of etha-nol and ethyl acetate is a simple, cheap and interesting blend as an alternative for plant baits for R. Multidimensional gas chromatography could gqzeuse provide an enhancement of detection capacity leading to a better identification and quantification of trace components.

A total of molecules were identified in odours from date palm. Among all chromatoraphie, a mixture of ethanol and ethyl acetate 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.

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