Abstract

The main vector of malaria in sub-Saharan Africa, , is subdivided into five chromosomal forms. Three of them (i.e., BAMAKO, SAVANNA, and MOPTI) are found in sympatry in Mali, where MOPTI can be distinguished from the other two forms based on differences in the ribosomal DNA locus. However, no molecular markers are available to distinguish BAMAKO from SAVANNA. We examined the banding patterns of 139 amplified fragment length polymorphism primer combinations in an attempt to identify diagnostic differences between SAVANNA and BAMAKO. Despite screening > 10,000 bands, no diagnostic differences were found. However, additional AFLP analyses indicated that BAMAKO is genetically differentiated from SAVANNA, with a significant Φ value of 0.072. This could indicate that gene flow between these forms is restricted in at least some portion of the genome and the lack of identifiable fixed differences between the two forms is probably due to their recent origin.
