In both sites, the majority of swarms were recorded above visual markers localised among houses. In Soumousso, a wooded area of savannah, 108 pairs caught in copula from 205 swarms were sampled; in VK7, a rice growing area, 491 couples from 250 swarms were sampled. If segregated swarms were the norm in both sites, many visual markers were shared by the two forms of An. gambiae. Furthermore, mixed swarms were collected annually in frequencies varying from one site to another, though no mixed inseminations were recorded, corroborating the low hybrid rate previously reported in the field. The occurrence of inter-specific mate-recognition mechanisms, which allow individuals to avoid hybridisation, is discussed. specialized PALUDISME VECTEUR MOUSTIQUE COMPORTEMENT ESSAIM ACCOUPLEMENT IDENTIFICATION MILIEU RURAL VARIATION SAISONNIERE VARIATION TEMPORELLE ETUDE REGIONALE ETUDE COMPARATIVE TECHNIQUE PCR BURKINA FASO 052ANOPAL02 Beier J ed. edt IRD Lees R.S. ed. edt IRD Chadee D.D. ed. edt IRD Gilles J.R.L. ed. edt IRD 132 Suppl.
