Phylogeny of hard- and soft-tick taxa (Acari: Ixodida) based on mitochondrial 16S rDNA sequences.
The derived phylogeny failed to support a monophyletic relationship among members of Ornithodorinae and supported placement of Argasinae as basal to the Ixodidae, suggesting that hard ticks may have originated from an Argas-like ancestor, and supports earlier suggestions thathard ticks did not evolve until the late Cretaceous.

The tools and information presented provide a means for early detection and characterization of kdr that is critical to the development of strategies for resistance management and showed a high rate of recombination even though the two codons are only separated by a ~250 bp intron.
Population genetics of Ixodes scapularis (Acari: Ixodidae) based on mitochondrial 16S and 12S genes.
Analysis of sequence variation in the 16S and 12S mitochondrial ribosomal DNA genes suggests that I. scapularis arose in the South but that a large geographic split gave rise to 2 distinct lineages now interbreed and are partially sympatric.
Mitochondrial gene order is not conserved in arthropods: prostriate and metastriate tick mitochondrial genomes.
The entire mitochondrial genome was sequenced in a prostriate tick, Ixodes hexagonus, and a metastriate tick, Rhipicephalus sanguineus. Both genomes encode 22 tRNAs, 13 proteins, and two ribosomal…
A FORTRAN program for the calculation and analysis of two-locus linkage disequilibrium coefficients
A FORTRAN program was written that calculates composite linkage disequilibrium coefficients from genotypic data and output obtained from analysis of allozyme data collected from natural subpopulations of the house fly are included to illustrate features of the program.
Genomic analysis of detoxification genes in the mosquito Aedes aegypti.
Comparative genomics of small RNA regulatory pathway components in vector mosquitoes
Analysis of Argonaute and PIWI subfamily genes suggests that the small regulatory RNA pathways of the major arbovirus vectors, Ae.
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 and demonstrated that small samples inflate FST and linkage disequilibrium.

Regression analysis of geographic distances and F(ST) values indicated that collections were genetically isolated by distance in the Pacific and the Yucatan, but not among collections in the northeast, suggesting extensive gene flow along the Pacific coast.
