Mitochondrial cytochrome oxidase I in tetranychid mites: a comparison between molecular phylogeny and changes of morphological and life history traits
Part of the mitochondrial cytochrome oxidase subunit I (COI) gene is sequenced in 20 species of phytophagous mites belonging to nine genera and two families, including several agricultural pests, and the phylogeny based on COI sequences was inferred using the maximum likelihood method.

Based on the fixed differences revealed by the mtCOI comparison of known B. tabaci biotype sequences, two diagnostic tests for discriminating between Q and B and non-Q/non-B biotypes were developed and allowed an absence of the B biotype and presence of the Q biotype in the Greek samples to be determined.
Inducible transgenic mice reveal resting dendritic cells as potent inducers of CD8+ T cell tolerance.
Direct amplification of length polymorphisms (DALP), or how to get and characterize new genetic markers in many species.
This method was used to detect micro-deletions/insertions and microsatellite DNA loci useful in population genetics studies, but it could be applied in many other fields of biology, such as genome mapping for definition of polymorphic sequence tagged sites, directly localized on a genetic map.

Estimations of the genetic relatedness between pairs of individuals indicated that the distances between Pair of sisters and unrelated mites in the greenhouse were not significantly different, suggesting that mites do not tend to form patches that reside close to the point of birth.
Transposable element polymorphism of Wolbachia in the mosquito Culex pipiens: evidence of genetic diversity, superinfection and recombination

It is established that Wolbachia infection is near to or at fixation in worldwide populations of the C. pipiens complex, indicating a strong worldwide differentiation independent from mosquito subspecies type, except in the UK.

ABSTRACT The extrachromosomal DNA of Sodalis glossinidius from two tsetse fly species was sequenced and contained four circular elements: three plasmids, pSG1 (82 kb), pSG2 (27 kb), and pSG4 (11 kb),…
Microsatellite sequences are under‐represented in two mite genomes
Congruency of Southern analysis and screening of partial genomic libraries indicates an under-representation of microsatellite sequences in the two mite genomes, with the potential of the scarce repetitive DNA isolated from mites to serve as population genetics markers.
NOBLAST and JAMBLAST: New Options for BLAST and a Java Application Manager for BLAST results
UNLABELLED NOBLAST (New Options for BLAST) is an open source program that provides a new user-friendly tabular output format for various NCBI BLAST programs without any use of a parser and provides E-value correction in case of use of segmented BLAST database.
DNA sequences and cross‐breeding experiments in the hawthorn spider mite Amphitetranychus viennensis reveal high genetic differentiation between Japanese and French populations
The post‐zygotic incompatibilities in A. viennensis cannot be explained by the presence of Wolbachia but to some extent by mite genome divergence resulting from limited gene exchange between allopatric populations.
