Population genetics with RAPD-PCR markers: the breeding structure of Aedes aegypti in Puerto Rico.


:RAPD-PCR polymorphisms at 57 presumptive loci were used to examine the breeding structure of the mosquito Aedes aegypti in Puerto Rico. Mosquitoes were sampled from 16 locations in six cities and samples were located in a nested spatial design to examine local patterns of gene flow. Allele frequencies were estimated assuming (1) that genomic regions amplified by RAPD-PCR segregate as dominant alleles, (2) that genotypes at RAPD loci are in Hardy-Weinberg proportions, (3) identity in state (iis) among dominant amplified alleles and (4) iis among null alleles. The average genic heterozygosity was 0.354, more than twice the level detected in earlier allozyme surveys. Nested analysis of variance indicated extensive genetic differentiation among locations within cities. Effective migration rates (Nm) among cities were estimated from FST assuming an island model of migration. Estimates of Nm ranged from 9.7 to 12.2 indicating a high dispersal rate. The large number of polymorphisms revealed by RAPD-PCR allowed the distribution of FST and linkage disequilibrium to be examined among loci and demonstrated that small samples inflate FST and linkage disequilibrium. No linkage disequilibrium maintained through epistasis was detected among alleles at the 57 loci.
