“…The phylogeographic pattern of mtDNA in O. furnacalis would belong to category II, which is characterized by the presence of pronounced phylogenetic gaps in a gene tree and co-occurrence of major lineages over a wide area. In insects and related animals, reports of the category II pattern for mtDNA appear to be limited to the botfly Dermatobia hominis (Geurgas et al , 2000) and the spider mite Tetranychus urticae (Hinomoto et al , 2001). Avise (2000) argued that most of the category II patterns in mitochondrial phylogeography probably involve zones of secondary admixture between allopatrically evolved populations or species.…”

The genealogy and diversity of the mitochondrial cytochrome oxidase subunit II (COII) gene were investigated for Ostrinia furnacalis in Japan. A preliminary examination of mitochondrial lineages in China and the Philippines was also made. Two lineages (A and B) were found in the COII gene. Lineage A was frequent throughout the Japanese main islands (Hokkaido, Honshu, Shikoku and Kyushu), while the frequency of lineage B varied among these islands. No clear patterns of geographical population structure were found. Population genetic features suggested that the O. furnacalis population harboring the lineage A mitochondria expanded in the recent past, while lineage B showed weak signals of a population expansion. It is not clear whether the two lineages of mtDNA evolved in separate or identical geographical regions. We discuss two hypotheses regarding the two lineages of mtDNA: a cryptic race/species hypothesis and a selective sweep hypothesis.

Abstract.Dermatobia hominis is a fly endemic to and widely distributed throughout the Americas; it is found from the southern regions of Mexico to Argentina. However, because of widespread travel, myiasis has become common in countries where neither the disease nor the species that cause this infection are endemic. Central Mexico, for instance, is not a region where myiasis is endemic. We, thus, describe three cases of D. hominis myiasis: two autochthonous cases from the southern part of Mexico and one imported from Costa Rica. In addition, morphological and genetic identification was performed on the maggots extracted from the patients.

“…The most commonly used molecular markers include mtDNA and nuclear DNA (random amplified polymorphic DNA–polymerase chain reaction, restriction fragment length polymorphism, polymerase chain reaction–restriction fragment length polymorphism, and simple sequence repeats, among other techniques). Although there has been progress in the molecular genetics of myiasis, previous studies have focused on only a few species, most of which are distributed in the New World …”

“…Both phenomena might explain the wide distribution of this fly in Central and South America. However, there are few available sequences and molecular studies performed regarding the genetic variation and population structure of this species . The only study regarding the genetic diversity among populations of Dermatobia was described by Domingues‐Bitarello et al .…”

Myiasis caused by Dermatobia hominis: countries with increased risk for travelers going to neotropic areas

et al. 2016

Here, we review the human botfly (Dermatobia hominis), which belongs to a group of Diptera generically known as "myiasis-causing flies," characterized by the ability of their larvae to develop in animal flesh. In addition to its medical and economic importance, there is an academic interest in this botfly because of its peculiar biology, particularly because a phoretic diptera is needed to complete the life cycle. The larvae penetrate the host's skin, causing furuncle-like lesions that are pruritic, painful, and resemble subcutaneous nodules, producing irreversible perforations in the skin. Although D. hominis is distributed from Mexico to Argentina, a review performed by our working group from 1999 to 2015 determined that the countries with the highest infection rates in travelers are Belize, Bolivia, and Brazil. Interestingly, infected men show a higher variation in the distribution of the lesions than in women. Many treatment schemes have been suggested, including the application of highly dense liquids to the lesion to cause anoxia in the D. hominis larvae. We showed, for the first time, a Bayesian inference between D. hominis and other myiasis-causing flies. The flies grouped into two main clusters according to their capacity to produce facultative and obligatory myiasis, and D. hominis was phylogenetically close to Cuterebra spp.
