We showed that the mean TE insertion site number and the within-population insertion site polymorphism globally differed between the M and S molecular forms. The comparison of the TE insertion profiles of the populations revealed a significant differentiation between these two molecular forms (0.163 < Phi(ST) < 0.371). We cloned several insertions of a non-LTR retrotransposon (Aara8) that were fixed in one form and absent in the other one. The only insertion that could be clearly located on a chromosome arm mapped to cytological division 6 of chromosome X, confirming the importance of this region in the ongoing speciation between the M and S molecular forms.specializedAnopheles gambiaeinsertion polymorphismmolecular formspopulation geneticsspeciationtransposable elements052 16244145220070962-1083http://www.documentation.ird.fr/hor/fdi:01003777710.1111/j.1365-294X.2006.03150.xIRD BondyF A010037777http://www.documentation.ird.fr/hor/fdi:010037777http://www.documentation.ird.fr/intranet/publi/2007/02/010037777.pdfAccès réservé (Intranet de l'IRD)IRD - Base Horizon / Pleins textes2007-03-012010-08-04fdi:010037777<languageTerm authority="iso639-2b">fre</languageTerm>
