“…A mtDNA substitution rate frequently cited or estimated for insects is about 1% change per million years per lineage (Venanzetti et al, 1993;Brower, 1994;Funk et al, 1995), a value similar to that used in vertebrate studies (Vawter and Brown, 1986). These rates, however, generally apply to recently evolved taxa separated by divergences of less than 5 or 7% (Harrison and Bogdanowicz, 1995).…”

“…As usual, it is difficult to estimate rates of evolution and put reliable dates on events. Estimates of nucleotide sequence divergence in insect mtDNA all give rates slightly above 1 % per million years (2 % for pairwise divergence) (Venanzetti et al 1993 ;Brower 1994), which are mostly due to silent sites. The highest reported rate is 5.7 % for four-fold degenerate sites in Drosophila (Tamura 1992).…”

SUMMARYReproductive incompatibilities called cytoplasmic incompatibilities are known to affect a large number of arthropod species and are mediated by Wolbachia, a maternally transmitted microorganism. The crossing relationships between strains of potential hosts define their incompatibility types and it is generally assumed that differences between strains of Wolbachia induce different crossing types. Among all the described host species, the mosquito, ulex pipiens, displays the greatest variability of cytoplasmic incompatibility crossing types. We analysed mitochondrial and bacterial DNA variability in ulex pipiens in order to investigate some possible causes of incompatibility crossing type variability. We sequenced fragments of the fts gene, and the AjT-rich control region of the mtDNA. We also sequenced the second subunit of the mitochondrial cytochrome oxidase ( OII) gene, in ulex pipiens and a closely related species,. torrentium, in order to verify the usefulness of the AjT-rich region for the present purposes. No variability was found in the Wolbachia fts gene fragment, and very limited variation of the mitochondrial marker whatever the compatibility type or the origin of the host. A low variability was found in the AjTrich region and comparison of divergence of the AjT-rich region and OII gene between . pipiens and . torrentium did not reveal any special constraints affecting this region. In contrast to observations in other host species, variability of incompatibility crossing types is not due to multiple infections by distantly related Wolbachia strains.

“…Pairwise distances ranged from 5 to 18% in the ingroup, and distances among the sets of morphologically indistinguishable taxa from different host plants ranged from 8.2 to 10.4% (Kladothrips rugosus), to 8.7% (Oncothrips habrus), to 15.9% (Oncothrips antennatus). Given the rates of COI sequence divergence typically found among insects of 1.5-2% per million years (Venanzetti et al, 1993;Brower, 1994;Funk et al, 1995a and references therein), these data suggest that each of these three taxa represents a set of host-specific sibling species rather than a single polyphagous species. However, rigorous testing of this hypothesis requires estimates of genetic divergence within and between populations on the same host plant species.…”
