Sarcophaga (Liosarcophaga) dux (Diptera: Sarcophagidae): A flesh fly species of medical importance

BACKGROUND: Although tropical climate of Thailand is suitably endowed with biodiversity of insects, flies of medical importance is not well investigated. Using information from literature search, fly survey approach and specialist's experience, we review database of Sarcophaga (Liosarcophaga) dux Thomson (Diptera: Sarcophagidae), one of the priorities flesh fly species of medical importance in Thailand. RESULTS: This review deals with morphology, bionomics and medical involvement. Important morphological characteristics of egg, larva, puparia and adult were highlighted with illustration and/or micrographs. Search pertaining to molecular analysis used for fly identification and developmental rate of larvae were included. Medical involvement of larvae was not only myiasis-producing agent in humans and animals, but associated with human death investigations. CONCLUSIONS: This information will enable us to accurate identify this species and to emphasis the increase medically important scene in Thailand.

Gastrointestinal Myiasis by Larvae of Sarcophaga sp. and Oestrus sp. in Egypt: Report of Cases, and Endoscopical and Morphological Studies

Four cases of gastric or intestinal myiasis are reported. The cases contain 2 males (1 child 10 years old, and 1 adult 40 years old) and 2 females (1 girl 18 years old, and 1 adult 50 years old) from Minia Governorate, Southern Egypt. Three of them, including cases no. 1, 3, and 4, were gastric myiasis, and complained of offensive hematemesis of bright red blood. Minute moving worms, larvae of the fly, were found in the vomitus. On the other hand, case no. 2 had intestinal myiasis, and complained of abdominal distention, nausea, vomiting, and diarrhea. The stool of case 2 was mixed with blood, and minute moving worms were observed in the stool. Endoscopy was performed to explore any pathological changes in the stomach of the patients. The larvae were collected and studied macroscopically, microscopically, and us-ing a scanning electron microscope (SEM) to identify their species. Three different types of larvae were identified. The larvae isolated from case 1 were diagnosed as the second stage larvae of Sarcophaga species, and the larvae isolated from case 2 were the third stage larvae of Sarcophaga species. On the other hand, the larvae isolated from cases 3 and 4 were diagnosed as the third stage larvae of Oestrus species.

Revisão das duas espécies de Tapacura Tibana & Lopes, 1985 (Diptera: Sarcophagidae: Sarcophaginae) / Revision of the two species of Tapacura Tibana & Lopes, 1985 (Diptera: Sarcophagidae: Sarcophaginae)

Esta revisão apresenta um estudo da morfologia externa das espécies de Tapacura Tibana & Lopes 1985, especialmente da terminália masculina. Tapacura inclui atualmente duas espécies: T. mariarum Tibana & Lopes, 1985 e T. mexicana Lopes, 1988, que foram relacionados a Peckiamyia Dodge, Retrocitomyia Lopes e a Sinopiella Lopes & Tibana na descrição original. São apresentadas redescrições, ilustrações e uma diagnose genérica mais ampla. Uma comparação entre as espécies de Tapacura e aquelas dos gêneros relacionados tem mostrado que Tapacura é mais similar morfologicamente a Peckiamyia, especialmente porque ambos têm o 3º setor costal da asa com pequenas cerdas ventrais, o fêmur médio do macho sem ctenídio e o edeago muito reduzido e pigmentado.

This revision presents a study on external morphology of the species of Tapacura Tibana & Lopes 1985, especially of the male terminalia. Tapacura includes presently two species: T. mariarum Tibana & Lopes, 1985 and T. mexicana Lopes, 1988, which were related to Peckiamyia Dodge, Retrocitomyia Lopes and Sinopiella Lopes & Tibana in the original description. Redescriptions, illustrations and a broadest generic diagnosis are presented. A comparison between the Tapacura species and those of the related genera has showed that Tapacura is more morphologically similar to Peckiamyia, especially because both have the third costal section of the wing with ventral setulae, male mid femur without ctenidium and a very reduced and pigmented aedeago.
