    A survey was carried out to clarify the mosquito fauna of Yonagunijima located between Iriomote-jima and Taiwan. The mosquitoes were collected five times trom June 1977 through August 1981. In total, 26 species of 9 genera were recorded in the present survey. Among them, following 15 species were recorded for the first time from Yonagunijima : Mimomyia elegans, Mansonia uniformis, Uranotaenia ohamai, Uranotaenia annandalei, Aedes baisasi, Aedes vexans nipponii, Aedes lineatopennis, Culex nigropunctatus, Culex infantulus, Culex bicornutus, Culex pallidothorax, Culex ryukyensis, Culex bitaeniorhynchus, Culex tritaeniorhynchus, and Culex vagans. Tripteroides bambusa yaeyamensis, Aedes riversi, Culex bicornutus and Culex in-fantulus were predominant species and Aedes riversi was the most voracious biter in the forest area. Aedes vexans nipponii, Anopheles sinensis and Culex tritaeniorhynchus were commonly found in paddy fields and swamps, and Aedes albopictus and Culex pipiens quinquefasciatus were predominant in artificial containers and the most voracious biter around dwelling area. The important vector mosquitoes, Anopheles minimus and Aedes aegypti which were recorded before in this island, were not found in the present survey.

    The morphology of the sphaerocerid fly, Leptocera fuscipennis (Haliday) which frequented human dwellings around Haneda Tokyo International Airport was redescribed for the first time in Japan. The adult fly is halophilous, blackish brown in color and 1.5-2.0mm in length. Adults are frequently attracted to light in the evening. The larva breeds in moist layer of sludge under dry surface. The mature larva is of a whitish maggot and measures 4mm in length. The pupation occurred on dry material. The pupa is brown in color and 3mm in length. It takes 12-15 days to complete its immature life.

    A nuisance sphaerocerid fly, Leptocera fuscipennis (Haliday), breeding in the Sewage Disposal Site in Tokyo Bay was studied. From May to November, 1978,surveys were carried out in the migrated area by using a blacklight trap. The result showed that the migration occurred from the end of June to the middle of July. The largest numbers of the flies were captured in the middle of July. When the flies in a light trap per night increased to more than 1,000,dwellers often grumbled. The Sewage Disposal Site began to be filled with sea mud and sludge, which were precedently mixed with sea water, in 1972. In 1975,the muddy sludge appeared above sea water in the bay, and finally the almost whole area became a kind of swamp. This condition of sludge was very good medium for this fly to breed. The ephydrid fly, Ephydra japonica Miyagi, also inhabited water of the swamp, but did not actually migrate from the site. When L. fuscipennis became over-populated at the beginning of July, they seem to migrate under a certain condition of weather. A large number of flies were captured in the evening when north to east winds blew. Winds from this direction are annually observed at the end of rainy season. Very bright illumination standing in and around the air port also seems to have directed flies to the affected dwellings.

    This paper describes the food habit and seasonal population changes of Rattus rattus in sugar cane fields on Tokunoshima Island. The volume of ovule integument of the cycad Cycas revoluta, which was commonly planted around the fields, amounted to over 60% of stomach contents of the rats in November and February. The internode of sugar cane was only 12% of the contents in volume even in February when cane matured. The rat population increased in November when cane was immature, and decreased in May when the cane harvest was over. Larger rats were dominantly trapped in November and 76% of the rats weighed over 80g. Smaller or young rats were dominant in February and 61% of rats weighed 60g or less. These results suggest that rats move to the fields in autumn to eat the new ovules, and reproduce in winter under the thick cover of cane.

    Three new species of horse flies, Tabanus taiwanus, T. matsuzawai and T. fulvilineus are described based on the materials from Japan. These species have so far been considered as T. amaenus Walker, T. exoticus Ricardo and T. fulvimedius Walker, respectively. Diagnostic characters of them were presented. The males of respective species are newly described and figured.

    A colony of the larvae of Culex tritaeniorhynchus which was obtained in Toyama Prefecture by laboratory rearing of eggs deposited by wild caught females collected at a pig house surrounded by rice paddies, was shown to be highly resistant to organophosphorus insecticides. The values of LC-50 against malathion, fenitrothion, fenthion, cidial, BPMC, and p, p' DDT were 34,13.5,9.6,8.8,2.16,and 0.078ppm, respectively. It was presumed that repeated applications of organophosphorus insecticides against rice plant pests have resulted in the development of such resistances in this mosquito species, which mainly breeds in rice paddies and is known to be acting as the principal vector of Japanese encephalitis. From analysis of dosage-mortality regression lines of the larvae against malathion and fenitrothion, it was shown that the colony composed of a mixture of different populations with various susceptibility levels against the insecticides. In the study of esterase isozyme patterns of individual female adult mosquitoes reared from larvae that survived after exposure to 5ppm fenitrothion and 10ppm malathion, it was also shown that they were composed of heterologous populations with different active band patterns.

    The larval habitats of tabanids were surveyed at Yakushima and Tanegashima in 1970 and 1981. In total 5 and 4 species of tabanid larvae were collected from Yakushima and Tanegashima, respectively. Atylotus suzukii inhabited in tidelands. The main breeding places of Tabanus toshiokai and T. kanoi were wet mosses growing in moors and beside water falls, while T. takasagoensis, T. trigeminus and T. taiwanus mainly inhabited in paddy fields.

    A faunal survey of tabanid flies was made in Rebun and Rishiri Islands, Hokkaido, Japan on July 29 and 30,1982. Haematopota tristis and Hybomitra olsoi were collected in Rebun Island while Ha. tristis and Tabanus nipponicus were found in Rishiri Island. The tabanid fauna of these islands seemed simple and poor. One of the main reason of it seems to be the scarcity of the cattle and wild animals.
