The use of molecular markers has contributed to phylogeny and to the reconstruction of species' evolutionary history. Each region of the genome has different evolution rates, which may or may not identify phylogenetic signal at different levels. Therefore, it is important to assess new molecular markers that can be used for phylogenetic reconstruction. Regions that may be associated with specie...

Sand flies include a group of insects that are of medical importance and that vary in geographic distribution, ecology, and pathogen transmission. Approximately 163 species of sand flies have been reported in Colombia. Surveillance of the presence of sand fly species and the actualization of species distribution are important for predicting risks for and monitoring the expansion of diseases whi...

Unlike distinct species, closely related species offer a great challenge for phylogeny reconstruction and species identification with DNA barcoding due to their often overlapping genetic variation. We tested a sibling species group of pine moth pests in China with a standard cytochrome c oxidase subunit I (COI) gene and two alternative internal transcribed spacer (ITS) genes (ITS1 and ITS2). Fi...

The species belonging to Sclerodermus (Hymenoptera: Bethylidae) are currently the most important insect natural enemies of wood borer pests, mainly buprestid and cerambycid beetles, in China. However, some sibling species of this genus are very difficult to distinguish because of their similar morphological features. To address this issue, we conducted phylogenetic and genetic analyses of cytoc...

Specimens of Metasiro from its three known disjunct population centers in the southeastern US were examined and had a 769 bp fragement of the mitochondrial gene cytochrome c oxidase subunit I (COI) sequenced. These populations are located in the western panhandle of Florida and nearby areas of Georgia, in the Savannah River delta of South Carolina, and on Sassafras Mt. in South Carolina. This r...

The mtDNA sequences revealed that several of the fish studied were Hampala macrolepidota and Barbonymus gonionotus . objective this research was to learn pattern COI gene in establish a phylogenetic tree. Basic Local Alignment Search Tool-nucleotide (BLASTn) confirmed froma Ranau Lake, South Sumatera has 100% matching ranges species from Memberamo River (Indonesia), India, Bangladesh, Thailand ...

The soybean stem fly, Melanagromyza sojae, an Asian native insect, has successfully established in Brazil, Argentina, Paraguay and Bolivia. These countries are among the lead global producing nations, being collectively known as belt of South America. Infestation levels M. sojae grow by year, facilitated lack efficient management strategies. Previous studies have revealed a high number maternal...

OBJECTIVES Medical journals in Japan generally have appropriate policies regarding disclosure of conflicts of interest (COI). However, COI management depends on the staff members of each journal's editorial secretariat. This study's objectives were to find out (A) whether COI disclosure and the journal's role in it are clearly understood by the journal's secretariat staff, (B) how much experien...
