JOURNAL FREE ACCESSThe predatory ability of three species of yellow dung-fly (Scathophaga scybalaria, S. stercoraria and S. suilla) was investigated in the laboratory. The functional responses of male S. stercoraria was the best among the three species. Female S. suilla were considered to be the least effective predators under the experimental conditions. Predatory behaviour was also investigated. Both sexes of all three species fed usually from only one, but sometimes two body parts, of prey captured at high prey densities. The neck of the prey was the primary site for perforation and the face was the second for both sexes of the three species examined. The following sites of perforation seemed to be variable especially in S. scybalaria and S. stercoraria.View full abstractDownload PDF (576K) -

JOURNAL FREE ACCESSLaboratory studies were done to assess the effects of larval density within cow dung on the growth and development of Musca hervei Villeneuve. Various numbers of eggs were reared with a fixed amount of reconstructed cow dung. In general, high larval densities beyond a certain level caused a large decrease in sizes of subsequent pupae and adults, despite the fact that the ratio of pupal length to width was almost constant for all sizes in both sexes. Very small puparia, however, were thin-walled and fragile. These stunted pupae had a tendency to emerge into small adults, having corresponding size in heads and wings with the pupal size, in a shorter period than normal ones. There seemed to be a positive relationship between the pupal size and the survival period of subsequent adult flies in both sexes.View full abstractDownload PDF (734K) -

JOURNAL FREE ACCESSThe sarcophagine flesh flies have been classified into a lot of genera by the combination of the external and trivial genital characters on the basis of the classification by Rohdendorf (1937). As his system was not based on the phylogeny, there have been many problems especially about the delineation of the genera. The authors examined in detail 86 out of 129 species of the Sarcophaginae of the Oriental region, and propose systematics weighted by the homology of the male phallic structure after Roback's method (1954). The Sarcophaginae of the Oriental region is divided into three tribes, namely Raviniini, Tephromyiini and Sarcophagini, and consists of four genera, namely Ravinia (1 species included), Blaesoxipha (7 spp.), Harpagophalla (6 spp.), Sarcophaga (112 spp.) and unplaced (3 spp.). These genera are grouped by the presence and the shape of the median process and the styli according to the result of the evolution of the ventral sclerotization.View full abstractDownload PDF (1059K) -

JOURNAL FREE ACCESSThe susceptibility of 2 strains (Oahu and Hyogo strains) of Aedes albopictus to oral infection with chikungunya virus was compared. These strains showed different infection threshold and final content of the virus. Oahu strain was much susceptible than the Hyogo strain. Virus titers in individual mosquito of the Hyogo strain on 14th day post-infection ranged continuously between (10)^1 and (10)^3 PFU per mosquito. On the contrary, those of the Oahu strain were fallen into 3 groups such as negative (non-infective), low virus titer ((10)^3-(10)^4 PFU) and high virus titer ((10)^6-(10)^7 PFU).View full abstractDownload PDF (422K) -

JOURNAL FREE ACCESSThe efficiency of a dipper (15cm in diameter and 3cm in depth) in collecting Anopheles sinensis larvae in rice fields was examined experimentally at different larval densities and growth stages of rice plant. Mean number of larvae per dip was proportional to larval density at least within the density range 25-800 of each instar per m^2. The dipping efficiency was not influenced by the growth stages of rice plant.View full abstractDownload PDF (396K) -

JOURNAL FREE ACCESSThe females of Periplaneta americana and P. australasiae in the first stage of oothecal formation were irradiated on the head with UV rays to examine the daily change of their sensitivity to the UV rays. One group of these female cockroaches was reared under the photo-regimen of 12L : 12D, the light phase was continued from 7 : 00 to 19 : 00. The other group was kept in the light phase of 5 : 00 to 17 : 00. A 10-watt mercury lamp which emits UV rays mostly of 253.7nm was used for irradiation at the rate of 100μW. (cm)^<-2>. (sec)^<-1> for 10min as reported previously. The results of UV irradiation experiments on the head of both the groups revealed a daily change of UV sensitivity which was expressed as various inhibitory effects on the oothecal formation, depending on the time of the day when they were irradiated. The sensitivity of cockroaches to the UV irradiation seemed very low at the early light phase, but when irradiated during 5hr prior to light-off, they responded to the irradiation by depositing more or less abnormal oothecae. During the first 4hr of light phase, the inhibitory effect of the UV rays could not be detected in the females even when they were exposed with a larger dose of the UV rays. In contrast, when the females were severed at the optic tracts and irradiated on the head in the first 4hr of light phase, they deposited abnormal oothecae. From these results it is suggested that the physiological mechanism controlling the circadian rhythms in the cockroaches might have intercepted the effect of UV rays during the early light phase.View full abstractDownload PDF (809K) -

JOURNAL FREE ACCESSThe immature stages of three muscine species, Pyrellia tateyamensis Shinonaga, Mesembrina resplendens Wahlberg and Huckettomyia watanabei Pont et Shinonaga, occurring from wild brown bear dung were newly described and their characteristics of taxonomic and biological significance were discussed. The third instar larva of P. tateyamensis was of typical Muscini-type, and can be distinguished from those of the known Dasyphora-larva in having a pair of extraanal papillae. This larva also differs from that of P. cadaverina (Linnaeus) in the characteristics of posterior spiracles. The larval mode of life of M. resplendens was trimorphic obligatory coprophagous. The third instar larva of resplendens is partially related to those of Hydrotaeini and Phaoniinae-Mydaeinae, and can be distinguished from that of a Palaearctic species, M. meridiana Linnaeus in having doubled number of branches on anterior spiracles and by the characteristics of posterior spiracles, but extremely resemble that of M. mystacea Linnaeus described from Russia. Egg of H. watanabei was of typical muscine-type, but the larval characteristics have a close relationship to those of Phaoniinae and Mydaeinae. The third instar larva of this species seems to be facultative carnivorous.View full abstractDownload PDF (806K) -

JOURNAL FREE ACCESSIntersexes of the following three Japanese Culicoides species, the head and wing showed characteristic of the female, and its genitalia were morphologically male. In C. jacobsoni and a gravid C. sinanoensis possessed the heads similar to of the female, but the antennae showed intermediate characters between male and female and the imperfectly developed genitalia were the male ones. Three developed spermathecae were observed in female of C. aterinervis, C. oxystoma, C. sanguisuga, C. verbosus and Malaysian C. pampanqensis, which normally had tow sperma-thecae.View full abstractDownload PDF (749K) -

JOURNAL FREE ACCESSEgg-batches of Tabanus nipponicus Murdoch and Takahasi, 1969 were surveyed in 1979 through 1982. Only 11 egg-batches were collected during the period; 7 from 5 kinds of plants (mainly Cyperus microiria Steud.) growing in the pasture, 2 from 1 kind of plant in the forest, and 2 from 1 kind of plant in the pond indicating not so strong selectivity of oviposition plants as that of aquatic species in general. The height of oviposition sites ranged from 18 to 192cm above the ground or water surface. The egg-batches were light yellowish brown in color, and roughly conical or semioval in shape with 3 to 4 layers of eggs. Average number of eggs per batch was 278. Seven batches (64%) were parasitized by wasps.View full abstractDownload PDF (547K) -

JOURNAL FREE ACCESSTwo males of the parasitic calliphorid fly Melinda itoi Kano 1962 were obtained from the slug, Incilaria bilineata (Benson) in April, 1976. The slug was one of those which were collected on March 25,1976 in the cracks of the bark of an old Ume-tree (Prunus mume Sieb. et Zucc.) growing beside the brook of a hilly village (Ohyagi, Moroyama-cho, Saitama) and kept alive in our laboratory at 25℃ from that time on. The movement of the maggots in the slug body was recognized three days after collection. Two days after that, they came out of the slug and pupated on the bottom of the glass container. After 12 days (April 11), the adult flies appeared. So far as we know, this is the first case of the parasitic fly emerged from the slug in Japan.View full abstractDownload PDF (311K) -

JOURNAL FREE ACCESSMite faunas in house dust samples collected from homes of children with Kawasaki disease (Mucocutaneous lymphnode syndrome; MCLS) living in the southern parts of Japan were examined. Average number of mites contained in 0.5g of these dust samples was 657 (n=24,range 40-3608). The number was not significantly different from that of our previous report in Kanto district. The number was not correlated with risk scores of MCLS (r=0.050). There was no specific mite species in dusts from homes of children with Kawasaki disease. The number of Dermatophagoides farinae was lower in dusts from Kawasaki disease than that from control dusts of previous report. Dermatophagoides pteronyssinus was found in all house dust samples. Rate of mites of Cryptostigmata seemed larger than that of our previous report. In summary, mite fauna in dust samples from homes of children with Kawasaki disease was not conspicuously different from the fauna of normal control house dusts in our previous reports.View full abstractDownload PDF (469K) -

JOURNAL FREE ACCESSThe effect of the juvenile hormone analogue, methoprene, as an oviposition regulator was examined using an autogenous mosquito Culex pipiens molestus. Either when the mosquitoes were fed on methoprene with sugar solution or when they were exposed to filter paper treated with methoprene, follicle maturation was varied and oviposition was inhibited. Moreover, it was confirmed that methoprene applied topically at 0.01μg/female was affected reproduction. Upon dissection the females which had oviposited were seen to have eggs retained in their ovaries, whereas those which had not oviposited contained follicles at various stages of maturation.View full abstractDownload PDF (449K) -
