The samples were collected in three villages in Burkina Faso (West Africa), where An. gambiae M and S molecular forms and An. arabiensis live sympatrically. The aim was to compare the cuticular hydrocarbon (CHC) composition of individual field specimens of these three taxa, to highlight possible differences among them. All the samples analysed by GC-MS (55 individuals and eight pools) were characterized by the same 48 CHCs and 10 oxygenated compounds. The 19 most abundant CHCs were quantified in 174 specimens by GC-FID: quantitative intra-taxon differences were found between allopatric populations of both An. arabiensis and S-form. Inter-taxa quantitative differences in the relative abundances of some hydrocarbons between pairs of sympatric taxa were also found, which appear to be mainly linked to local situations, with the possible exception of diMeC(35) between An. arabiensis and S-form. Moreover, MeC29 shows some degree of differentiation between S- and M-form in all three villages. Possible causes of these differences are discussed. specialized cuticular hydrocarbons gas chromatography Anopheles malaria Africa semochemicals mating recognition system 052 37 4 389-398 2007 0965-1748 https://www.documentation.ird.fr/hor/fdi:010037949 10.1016/j.ibmb.2007.01.002 0965-1748 [F B010037949] https://www.documentation.ird.fr/hor/fdi:010037949 https://www.documentation.ird.fr/intranet/publi/2007/06/010037949.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2007-06-28 2017-08-23 fdi:010037949 fre
