It is shown that deaminations during replication and other mutations contribute more than selection on amino acid sequences to strand compositions of G and C, and that the replication process has a stronger affect on A and T content than does transcription.

Comparative mitogenomics of Braconidae (Insecta: Hymenoptera) and the phylogenetic utility of mitochondrial genomes with special reference to Holometabolous insects

Comparative studies indicate that mitochondrial genomes are a useful phylogenetic tool at the ordinal level within Holometabola, at the superfamily within Hymenoptera and at the subfamily level within Braconidae, suggesting that the utility of mitochondrial genomes is likely to be a valuable tool for systematics in other groups of arthropods.
Phylogenetic relationships among the Braconidae (Hymenoptera: Ichneumonoidea) inferred from partial 16S rDNA, 28S rDNA D2, 18S rDNA gene sequences and morphological characters.

It is found that this species is highly differentiated, coupled with an estimated population expansion date of at least 60 000 bp and the genetic differentiation of this borer is probably attributed to climatic and/or geological events and subsequently strengthened by the domestication of rice.

Comparison of these four antimicrobial peptide gene families with those of the Western honeybee revealed that there are many similarities in the quantity and amino acid components of peptides in the abaecin, defensin and apidaecin families, while many more hymenoptaecin peptides are found in the Asiatic honeybee than those in the Western bee.

The utility of five gene segments was explored among blowfly species from two distinct geographic regions, China and Pakistan, and demonstrate a universal utility of these gene segments in the molecular identification of flies of forensic importance.
Immature Development of Cotesia vestalis (Hymenoptera: Braconidae), an Endoparasitoid of Plutella xylostella (Lepidoptera: Plutellidae)

Immature development of C. vestalis was studied by dissecting parasitized hosts in the laboratory at 25 Âą 1°C and 60â65% RH and showed that the egg matured in 2 d; Larvae seemed to have three instars; the first two larval instars molted inside the host, and the third instar emerged from the host to spin a cocoon.
Multiple Lines of Evidence from Mitochondrial Genomes Resolve Phylogenetic Relationships of Parasitic Wasps in Braconidae

The strand-asymmetry of base composition in the mitochondrial genomes of braconids is reversed, providing evidence for monophyly of the Braconidae, and multiple uses of mitochondrial genomes for phylogenetic inference in Braconids are illustrated.
