“…In Honshu, Japan, C. nigribarbis and A. grahami are the predominant species in lowlands (Kano et al, 1965;Kurahashi et al, 1991), and C. nigribarbis, C. vomitoria, C. vicina, and A. grahami coexist in high altitudes (Shinonaga, 1965;Arakawa et al, 1991). From the present results, in Hokkaido, whose latitude is lower than northern Europe and higher than Honshu (Japan), C. vomitoria predominated from lowlands to high altitude areas.…”

“…From a hygienic point of view the season when C. vomitoria is important in houses of domestic animals and surroundings is autumn (October) in Hokkaido. Kano et al (1965) reported that C. nigribarbis had a bimodal seasonal distribution with peaks in April and November, and it was never collected in summer in Honshu, Japan. The present result suggests that this species has a tendency to appear in June and October in lowlands, but it is unimodal in upland to highland areas with a peak in summer in Hokkaido.…”

“…In eastern Asia, the studies of distribution, abundance, life histories, and migration of blowflies have been done in Honshu and Kyushu, Japan (Buei, 1959;Kano et al, 1965;Kurahashi et al, 1984Kurahashi et al, , 1991Kurahashi et al, , 1994Kawai et al, 1985;Kurahashi, 1991;Arakawa et al, 1991;Tachibana and Numata, 2006). However, little is known of the bionomics and characteristics of blowflies in Hokkaido, the northernmost island of Japan.…”

Seasonal and spatial distributions of blowflies in relation to reproduction were investigated by baited traps in eight sites from lowland to high mountainous areas in Hokkaido, Japan. A total of 6,571 blowflies consisting of seven species in three genera was collected. The most predominant species was Calliphora vomitoria (Linnaeus) (5,946 flies, 90.5%), followed by C. nigribarbis Vollenhoven (537 flies, 8.2%). The remaining five species (Triceratopyga calliphoroides Rohdendorf, C. vicina Robineau-Desvoidy, C. loewi Enderlein, C. subalpina (Ringdahl), and Aldrichina grahami (Aldrich) were few in numbers. Calliphora vomitoria had the highest peak in autumn (October) in lowland to upland areas (70 m, 400 m, and 500 m), and it was also abundant from July to September in highlands (1,000-1,150 m). Calliphora nigribarbis was present in low numbers, but it was comparatively abundant in summer in highland areas (1,000-1,150 m). Emergence traps yielded 1,441 individuals from four species (C. vomitoria, C. nigribarbis, C. vicina, and T. calliphoroides), showing their reproductive potential in each site. Of these, C. vomitoria and C. nigribarbis emerged at 500 m (Nissho Pass) and 1,850 m (Mt. Kurodake) in August, indicating that they have reproductive cycles at upland to high mountainous areas. Further, adult emergence of C. vomitoria in 2009 from traps placed in the preceding autumn at Mt. Kurodake showed that this species can hibernate at high altitudes. For C. vomitoria, 62.7-84.1% of females had matured follicles (stages IV-V), and mating rates were very high (99.5-100%) in lowland and uplands in October. At Mt. Kurodake, high percentages of females of C. vomitoria and C. nigribarbis had mature follicles from July to October, with high mating rates. Life histories and reproduction of blowflies in Hokkaido were discussed.

Summary 1.Blowfly infestation of sun-drying fish is a major economic problem in many developing countries of Asia, Africa and the Pacific. To consider the ecology of infestation, adult and larval blowfly populations were monitored between 27 October 1997 and 27 April 1999 at a fish landing and drying site, approximately 5 km north of Calicut, in Kerala state on the coast of south-west India. 2. During the 548-day sampling period, a total of 96 953 adult Diptera was collected from 16 sticky targets, placed inside and outside eight fish-storage sheds. Of these, 91 912 (95%) were Chrysomya megacephala , 3719 (4%) were other Calliphoridae and 1322 (1%) were other species, largely Sarcophagidae. 3. The population of C. megacephala showed pronounced seasonal fluctuations in response to climate, particularly relative humidity. Significantly shorter-frequency fluctuations within fish-processing sheds were also evident, the periodicity of which corresponded approximately to C. megacephala generation cycles. Spatial variation in C. megacephala abundance was evident within the site, higher populations occurring closest to the beach and numbers declining with distance inland. 4. The pattern of drying fish infestation by C. megacephala broadly followed changes in the density of adult flies and the seasonal change in weather, with peaks during the monsoon and troughs in the dry hot periods. High relative humidity played a significant but secondary role in increasing infestation. 5. Quantification of the relationship between larval infestation and percentage fish loss suggests that, given the infestation levels observed, between 10% and 60% post-harvest wet weight losses would be expected in the monsoon period, depending on the species of fish landed. 6. The study emphasizes the importance of developing a clear understanding of the basic ecology and spatial and temporal dynamics of an insect pest, prior to the design or implementation of any pest management programme.

“…It is commonly found in humid forests with low vegetation throughout Japan (Kurahashi, 1981). Regarding seasonal fluctuation of this fly species in Japan, adults occur from May to December in Kyoto (Watanabe, 1956) and from April to November in Tokyo, with a peak in October (Kano et al . 1965).…”

Suspected intestinal myiasis due to Dryomyza formosa in a Japanese schizophrenic patient with symptoms of delusional parasitosis

A third-stage larva of Dryomyza formosa (Wiedemann) (Diptera: Dryomyzidae) was found in the fresh stool of a 27-year-old Japanese woman resident of Shiobara, 150 km north of Tokyo, on 16 November 1998. This is the first record of myiasis due to Dryomyza. Detection of this maggot (2cm long) by the patient herself was associated with her longstanding delusion of abdominal parasitosis as a symptom of chronic schizophrenia. Circumstantial evidence agreed with this being a genuine case of intestinal myiasis, apparently due to accidental ingestion of the insect, with no signs that the patient had contrived the report, nor that the maggot had invaded the stool post-defaecation. This case draws attention to the likelihood that some personality states are predisposed to noticing and reporting myiasis, when it occurs. We review other conditions (mental and physical) that are more prone to myiasis.
