Table 2.
Genetic diversity and structure within five Cimex lectularius infestations for which multiple refugia were sampled. Total is the value obtained when individuals for all localities were pooled together. Heterozygosity and F-statistics were calculated within and among C. lectularius infestations at 19 loci. Significance of FST values was calculated after 10 000 permutations

Two loci were omitted because they failed to amplify for any individual in one infestation.
n, Number of individuals; LM, Number of monomorphic loci; HE, Expected heterozygosity; Ho, Observed heterozygosity.
†
Sample sizes standardized to the smallest number of individuals for a locus.
NS, nonsignificant (P > 0.05)
*
significant (P < 0.01)
**
highly significant (P < 0.001).
