“…More than fifty species of Diptera belonging to various families are considered as phoretic vectors such as: Mucidae , Calliphoridae , Sarcophagidae , Fanniidae , Culicidae , Tabanidae , amongst others [ 17 ]. The quantity of D. hominis eggs placed in a phoretic vector varied, also Limatus durhamii was only reported with 3 eggs [ 18 ] , while Haematobia irritans with 21 eggs [ 19 ] , Sarcopromusca pruna with 18 eggs [ 20 ], Ophyra aenescens with 41 eggs [ 21 ]. In our study we report Ps.…”

Introduction Dermatobia hominis belongs to the Cuterebridae family, Diptera order; These flies inhabit tropical regions where they are called "fly of death" since the larvae are capable of causing lesions in domestic animals, wild animals including humans, the adult females of D. hominis capture other dipteran to oviposit their eggs on them (phoresis), when hematophagous mosquitoes land on an animal and / or human in order to feed on their blood, the eggs hatch and the larvae immediately penetrate the skin where they will develop to later abandon the host, then in the soil and / or other moist substrate the pupal stage develops, finally new adult flies will emerge from the pupae. Objective The primary goal of the present study was to determine as first record, the presence of Psorophora ferox infested with eggs of Dermatobia hominis, Peru. Methodology The present study was carried out in an area of the private reserve "El Vencedor", located within the city of Pucallpa, Ucayali Region-Perú. The area is characterized by being humid tropical, with an average temperature of 26ºC and humidity of 92%, while the annual precipitation is approximately 1570 mm3. The capture method was carried out with the help of a hand net type "butterfly" or also called Jama. Results A total of 668 mosquitoes of different species were collected, the most abundant being Psorophora albigenu and Psorophora ferox, which represented 88.72% and the least abundant was Culex coronator and Uranotaenia apicalis with 0.15% of the total sample collected. Conclusions Within these specimens it was captured a mosquito of the species Ps. ferox with the presence of 8 eggs of D. hominis, of which 3 would have hatched, while in the remaining 5, the larvae would remain inside the eggs.

“…2 Mais de 50 espécies podem carrear os ovos, destacando-se a Sarcopromusca pruna, Musca domestica e Haematobia irritans. 3 Quando o inseto pica um indivíduo, os ovos entram em contato com o calor da pele humana, eclodem e, então, a larva penetra na pele, ainda que esta esteja íntegra. 1 A larva se mantém no interior da pápula ou nódulo formado por cinco a dez semanas, período em que passa pelos primeiro, segundo e terceiro estágios larvais.…”

Dermatobia hominis é um dos principais agentes etiológicos da miíase furunculoide. É mais comum em países intertropicais e induz a formação na pele de pápula ou nódulo com orifício central. Quando o diagnóstico da lesão não é realizado ou quando a larva não é estruída, pode evoluir para a formação de uma tumoração. Relatamos um caso raro de lesão simuladora de lipoma no membro inferior de um homem morador da zona rural. O diagnóstico etiológico foi realizado por meio do exame histopatológico, sendo possível visualizar um cisto com material exógeno ao centro, compatível com D. hominis, em nítido processo de degradação.

There are more than 50 identified species that are phoretic on D. hominis , but Sarcopromusca pruna , Stomoxys calcitrans , Musca domestica , Fannia pusio , and Haematobia irritans are considered the most important species for transporting D. hominis eggs …”

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

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.
