We present the first two mitochondrial genomes of Muscidae dipterans for the species Haematobia irritans (the horn fly) and Stomoxys calcitrans (the stable fly). Typical insect mtDNA features are described, such as a high A+T content (79.1% and 78.9%, respectively), the preference for A+T-rich codons, and the evidence of a non-optimal codon usage. The(More)
The complete sequence of the mitochondrial genome of the screwworm Cochliomyia hominivorax was determined. This genome is 16,022 bp in size and corresponds to a typical Brachycera mtDNA. A Serine start codon for COI and incomplete termination codons for COII, NADH 5 and NADH 4 genes were described. The nucleotide composition of C. hominivorax mtDNA is 77%(More)
In view of the medical, sanitary and forensic importance of Chrysomya species, a knowledge of their nucleotide sequences would be useful for the molecular characterization of this genus, and would help in designing primers and in improving the molecular identification of Calliphoridae species. In this work, the mitochondrial genome of the blowfly Chrysomya(More)
This work describes the molecular characterization of the cytochrome c oxidase subunit I (COI) gene of the mitochondrial DNA from three species of great medical and veterinary importance: the horn fly, Haematobia irritans, the stable fly, Stomoxys calcitrans and the house fly, Musca domestica (Diptera: Muscidae) (Linnaeus). The nucleotide sequence in all(More)
“Myiasis-causing flies” is a generic term that includes species from numerous dipteran families, mainly Calliphoridae and Oestridae, of which blowflies, screwworm flies and botflies are among the most important. This group of flies is characterized by the ability of their larvae to develop in animal flesh. When the host is a live vertebrate, such parasitism(More)
The mtDNA control region (CR) and flanking genes of the blowflies Chrysomya albiceps, Chrysomya megacephala and Chrysomya chloropyga (Calliphoridae) were characterized. The most unusual feature found was the presence of duplicated tRNA sequences corresponding to trnI and a portion of trnQ. The partially duplicated trnQ was very likely a pseudogene since(More)
Despite the successful use of universal primers for amplifying insect mtDNA, specific regions remain difficult to recover and demand the use of taxon-specific primers. In this work, we describe a new set of primers for efficiently amplifying and sequencing the mtDNA control region and three tRNA gene clusters of dipterans of medical and veterinary(More)
The structure and evolution of the mtDNA control region (CR) and its flanking genes in economically important dipterans from the family Muscidae (Brachycera: Calyptratae), Haematobia irritans, Musca domestica, Atherigona orientalis, and Stomoxys calcitrans are presented in this paper, along with the description of short noncoding intergenic regions possibly(More)
UNLABELLED The Arthropodan Mitochondrial Genomes Accessible database (AMiGA) is a relational database developed to help in managing access to the increasing amount of data arising from developments in arthropodan mitochondrial genomics (136 mitochondrial genomes as of September 2005). The strengths of AMiGA include (1) a more accessible and up-to-date(More)
This study reports the molecular characterization of the mtDNA control region (called the A+T-rich region in insects) of five dipteran species which cause myiasis: Cochliomyia hominivorax Coquerel, Cochliomyia macellaria Fabricius, Chrysomya megacephala Fabricius, Lucilia eximia Wiedemann (Diptera: Calliphoridae) and Dermatobia hominis Linnaeus Jr (Diptera:(More)
