OBJECTIVES: To explore the number of necrophagous flies and seasonal distribution of common necrophagous flies at present in Beijing. METHODS: The specimens of necrophagous flies were collected by the methods of animal carcass, trapping and feeding. And the specimens were observed and counted after the classification and preservation. RESULTS: The necrophagous flies in Beijing belonged to 4 families, 9 subfamilies, 21 genera and 46 species, and 12 species of them were the first records in Beijing. The necrophagous flies had the characteristics of regional and seasonal distribution. CONCLUSIONS The data of seasonal distribution of necrophagous flies and common necrophagous flies in Beijing can provide reference for related research.

A case of furuncular myiasis was reported for the first time in a 29-year-old young Taiwanese traveler returning from an ecotourism in Peru. Furuncle-like lesions were observed on the top of his head and he complained of crawling sensations within his scalp. The invasive larva of botfly, Dermatobia hominis, was extruded from the furuncular lesion of the patient. Awareness of cutaneous myiasis for clinicians should be considered for a patient who has a furuncular lesion and has recently returned from a botfly-endemic area.

OBJECTIVE: In order to determine the major species of sarcosaphagous flies and their regular activity on carcass in Hohhot district. METHODS: Six rabbits were killed and placed outdoors at different time from July to October in Hohhot district. Some species of sarcosaphagous flies that appeared the cadavers were observed and identified. RESULTS: It showed that there are 10 main spieces belonging to 3 families and 8 genera were from Diptera, including Musa domestica domestica Linnaeus, Musa domestica vicina Maequart, Ophyra capensis (Wiedemann), Hydrotaea armipes (Fall.), Muscina stabulans (Fall.) from Museidae; Lucilia sericata (Meigen), Chrysomya megacephala (Fabricius), Lucilia cuprina (Wiedemann) from Calliphoridae; Boettcherisca peregrina (Robineau-Desvoiy), Parascarcophaga crassipalpis (Maequart) from Sacrophagidae. Besides, it showed obvious regulations that different species of sarcosaphagous flies appeared on carcass at different postmortem interval and the first part of carcass that sarcosaphagous flies appeared on. CONCLUSION It may be useful for estimating postmortem interval in Hohhot district.

Megaselia scalaris (Diptera: Phoridae) is one of the medically important insects. Maggots from a urine sample of a 5-year-old Saudi girl were examined microscopically for identification. These maggots were cultured to become adult flies. Larvae and adults were identified using standard keys. Protozoan flagellates were obtained from the gut of the larvae. This is the first report of M. scalaris as a causative agent of urinary human myiasis in Saudi Arabia.

We describe here a rare case of traumatic myiasis occurred in August 2014, caused by an association of 2 Diptera species, Sarcophaga tibialis Macquart (Diptera: Sarcophagidae) and Lucilia sericata (Meigen) (Diptera: Calliphoridae), in a domestic cat in northern Italy. Species identification was based on adult male morphology. The present case is the first report of S. tibialis as an agent of myiasis in Italy, and also the first ever report of myiasis caused by an association of S. tibialis and L. sericata. The cat developed an extensive traumatic myiasis in a large wound on the rump, which was treated pharmacologically and surgically. The biology, ecology, and distribution of S. tibialis and L. sericata are also discussed. A literature review is provided on cases of myiasis caused by S. tibialis, and cases of myiasis by L. sericata involving cats worldwide and humans and animals in Italy.

OBJECTIVE: To study the succession of sarcosaphagous insects and their regular activity on carcass in Shijiazhuang area. METHODS: Nine rabbits were sacrificed and placed at the same site during June to September in 2007-2009. The common species of sarcosaphagous insects were observed. RESULTS: Nine main species could be identified belonging to 3 families and 4 genera from Diptera, including Musca domestica (Linnaeus), Muscina stabulans (Fall én), Hydrotaea (Ophyra) capensis (Wiedemann), Hydrotaea (Ophyra) spinigera (Stein), Lucilia sericata (Meigen), Chrysomya megacephala (Fabricius), Boerttcherisca Peregrina (Robineau-Desvoidy), Parasarcophaga crassipalpi (Macquart) and Helicophagella melanura (Meigen). Eleven main species belonging to 4 families from Coleoptera include Nicrophorus concolor (Kraatz), Silpha carinata(Herbst), Nicrophorus fossor (Eneshas), Ptomascopus morio (Kraatz), Eusilpha bicolor (Fairmaire), Scarabaeus rugosus (Hausmann), Harpalus rufipes (DeGeer), Dolichus halensis (Schaller), Goncephalum pusillum (Fabricius), Cafius seminitens (Horn) and Aleochara pacifica (Casey). Two main species from 2 families were Tetramorium caespitum (Linnaeus) and Vespa velutina(Lepeletier). CONCLUSION It is evident that the succession of sarcosaphagous flies in Shijiazhuang with its unique geographical features. It may be used for estimating postmortem interval in Shijiazhuang area.

BACKGROUND: By frequent G-exposures cervical and lumbar spinal symptoms may be the factors to limit their flying performance and causes of acute and chronic spinal diseases. We examined not only the frequency and degree of spinal symptoms but inter-relationship between these symptoms and several factors according to aircraft type. METHODS: We surveyed 244 ROKAF aviators by questionnaires attending aerospace-medical aviator physiology class of aeromedical center. RESULTS: Exposured gravities are 8.23, 6.02, 5.89 and 5.38 +Gz in pilots of F-16, F-5, F-4 and trainer aircraft respectively. Pilots of trainer aircraft were most frequently exposured to a gravity in a month. 72.5% of F-16 aviators had neck pain and 82.6% of trainer aircraft low back pain. Spinal symptoms limited checking 6 in about 55% of aviators and air combat maneuver in over 30% of aviators. CONCLUSION: To improve combat performance by alleviation of spinal symptoms aircraft aviators may rest sufficiently and had better keep a correct posture while +Gz exposures. We need to invent stretching exercises for relaxing muscle stress and correct seating frame of aircraft. Skilled medical team and instruments for physiotherapy also needed in airbases.

OBJECTIVE: To document the arthropod succession pattern and to identify forensically important species in northeastern Egypt (32° 15' E and 30° 36' N) for the first time. METHODS: Carcasses were exposed in an open area for 60 days during summer season. Ambient daily temperature (maximum and minimum) and relative humidity (RH) were recorded and existing keys were used for identification of different species. RESULTS: During the period of study, the mean of maximum and minimum temperatures were 34.85 °C and 29.2 °C respectively, while the mean of RH was 53.5%. Four stages of decomposition were observed: fresh, bloat, decay and dry. The most abundant orders were found to be Diptera, Coleoptera and Hymenoptera. Arthropods were collected belonging to 4 families of Diptera: Muscidae, Fanniidae, Calliphoridae and Sarcophagidae. While there were 2 families of Coleoptera: Dermestidae and Histeridae. Monomorium species was the only Hymenoptera family in this study. CONCLUSION The present work provided a basis for further studies dealing with insect colonization of carcasses in different seasons and locations in Egypt.

OBJECTIVE: To study the species of sarcosaphagous insects. METHODS: Rabbits were killed and placed outdoors from March to November. Flies that appeared the cadavers were observed and identified. RESULTS: There are five main flies, i.e., Muscadomesticauicina, Lucilia sericata, C. Megacephala, S. fuscicauda, Aldrichiragrahormi. From midtime of April to the beginning of October, Muscadomesticauicina could be seen on the cadvers, however, Aldrichiragrahormi only could be seen before the beginning of May. Otherwise, Lucilia sericata, C. Megacephala, S. fuscicauda could be seen on the cadvers from March to the end of October. After the midtime of November, none of sarcosaphagous flies could be seen on the cadvers. On the other hand, maggots of sarcosaphagous flies could be seen often on the cadvers after adults of sarcosaphagous flies intruding 1 to 4 days, relating to temperature of environment. CONCLUSION If these flies history of life be studied. it is useful for estimating postmortem interval in Chengdu.
