| mark-release-recapture experiments with anopheles gambiae s.l. in banambani village, mali, to determine population size and structure. | mark-release-recapture experiments with anopheles gambiae s.l. were performed during the wet seasons of 1993 and 1994 in banambani, mali. all recaptured mosquitoes were identified to species by pcr analysis and, when possible, by chromosomal analysis to chromosomal form. two species of the an. gambiae complex were present: an. gambiae s.s. and an. arabiensis; their ratio differed greatly from one year to the next. three chromosomal forms of an. gambiae s.s. were found--bamako, savanna and mopti. ... | 1998 | 9513942 |
| molecular identification of sympatric chromosomal forms of anopheles gambiae and further evidence of their reproductive isolation. | three chromosomal forms of anopheles gambiae s.s., designated as bamako, mopti and savanna, were studied for diagnostic pcr assays based on the analysis of the x-linked ribosomal dna (rdna). the study was performed on a 1.3 kb fragment containing part of the 28s coding region and part of the intergenic spacer region. the amplified material was cut with fourteen restriction enzymes to detect restriction fragment length polymorphisms (rflps). the enzymes tru9i and hhai produced patterns of dna ban ... | 1997 | 9359579 |
| ecological genetic studies in the chromosomal form mopti of anopheles gambiae s.str. in mali, west africa. | among the sibling species of the afrotropical anopheles gambiae complex, the nominal taxon (an. gambiae s.str.) is the major malaria vector. its bionomics suggest a man-dependent speciation process which involves, in west africa, various incipient species chromosomally recognized by different combinations of 2r paracentric inversions. one of the most recent evolutionary steps of such a speciation process appears to be the chromosomal form mopti, which is associated with dry season irrigation in ... | 1994 | 7896141 |
| multilevel analyses of genetic differentiation in anopheles gambiae s.s. reveal patterns of gene flow important for malaria-fighting mosquito projects. | malaria control projects based on the introduction and spread of transgenes into mosquito populations depend on the extent of isolation between those populations. on the basis of the distribution of paracentric inversions, anopheles gambiae has been subdivided into five subspecific chromosomal forms. estimating gene flow between and within these forms of an. gambiae presents a number of challenges. we compared patterns of genetic divergence (f(st)) between sympatric populations of the bamako and ... | 2005 | 15677750 |
