    Stegopterna nukabirana n. sp. is described based on the specimens taken from the streams in the forest at the Eastern Daisetsu National Park, Hokkaido. The species seems to be closely related to Stegopterna sp. (nec. mutata MALLOCH) of Honshu, but differs from it in the structure of genitalia and mouth parts in female

    No representative of a tropical cockroach family Anaplectidae had been known from the present Japanese limits before the War, although Shiraki (1931) recorded "three" species from Taiwan. Surveys made after the War yielded one Anaplectella species from the Ryukyus and one new Anaplecta from Kyushu and Shikoku. A redescription of the former species and the description of the new Anaplecta were given in this paper. Brief notes on the other Taiwanese species were also added.

    A case of anaphylactic shock from the wasp, Vespa tropica, was recorded in Higashi-Yamanashi city, a typical agricultural area in Japan, on October 12,1976. This case was a 51-year-old female farmer who was stung on the nap by a wasp while working at her farm. Approximately ten minutes later, dyspnea and cloudiness of consciousness developed. When she was brought to hospital at twenty minutes after the wasp sting, blood pressure was unable to obtain and moist rales was audible all over the chest. At approximately 15 minutes on I. V. drip including predoning, nor-epinephrine, aminophyllin and histamics as well as on oxygen, initial symptoms were stabilized and consciousness became clear. The review of hospital charts revealed that ten patients had been treated for wasp or bee stings in the hospital of the present case during the period of October, 1975 to September, 1976. further epidemiological studies on wasp or bee stings need to be carried out. Desensitization therapy may be useful for those known to be hypersensitive to stings. It is also advisable that those especially in close contact with these insects be educated on the danger of their sting.

    A strong cross resistance among organophosphorus insecticides has evolved in the house fly, Musca domestica L., in various places of Japan. Insecticidal activity of prothiophos against these resistant house flies was determined by a topical application method in 1975 and 1976. The average (LD)_<50> value against these 37 resistant strains collected from 24 prefectures was 0.72μg/♀ fly, and the range of it's resistance ratios was 0.8 to 2.7. These results proved that prothiophos, although it belongs to the same organophosphorus group, has a good activity against the resistant populations.

    The schistosomiasis is widely scattered in the world and various control measures have been undertaken to reduce the population of intermediate snail hosts. In the present study, the killing efficiency of 9 kinds of tropical fishes were examined against the intermediate hosts of schistosomes. Fishes examined were Cichlasoma nigrofasciatum, C. biocellatum, C. elisalium, C. festivum, Tilapia galilaea, Anoptichthys jordani, Barbus tetrazona tetrazona and B. semifasciolatus. A fish was released into a polystyrene aquarium (23×17×21cm) along with 20 snails, and a sheet of Salan net was inserted horizontally into water at a level of 10cm from the bottom to prevent snails crowling out of the aquarium. Among 9 tropical fishes listed above, Cichlidae was more effective than Characidae or Cyprinidae to kill the snail, Biomphalaria glabrata. Besides, C. nigrofasciatum or convict cichlid was found to be most efficient. The number of B. glabrata killed by a C. nigrofasciatum increased with the increase of snail population from 20 to 60. However, it decreased when the water plant, Hydrilla verticillata, was placed into the aquarium with snails. For example, among 100 snails exposed to 5 fishes in a large aquarium (70×40×22cm), 45 were killed with plant while against 59 without plant. Oncomelania nosophora and Lymnea (Galba) ollura were killed by C. nigrofasciatum effectively as B. glabrata were. The youngs of the guppy, Poecilia reticulata were killed by all the tropical fishes tested within 48 hours.

    Two new species belonging to the genus Boettcherisca R. D. were found from Lesser Sunda Islands in Indonesia. The adults of these two species were trapped in the forests using decayed meat and fishes as bait, and colonized in the laboratory. Both species are endemic species in each island, Flores and Timor. The descriptions and figures of these new species are given in this paper.

    A study of mosquitoes was made in each season of 1972-1974,in Chushin District, Nagano Prefecture, Japan. Eleven species were caught in light-traps around human dwellings, includings a pig pen. Anopheles sinensis group predominated among the blood-sucking mosquitoes, and were followed by Culex pipiens pallens and Aedes vexans. The population density of Culex tritaeniorhynchus was assessed to be very low (Table 1). The peak activity occurred in August in A. sinensis group, and slightly earlier in C. p. pallens. The density of C. tritaeniorhynchus decreased after the middle of July in the pig pen. Nine species of mosquito larvae were collected from rice fields by a dipping method. Larvae of A. sinensis group and Culex orientalis predominated, while those of blood-sucking Culex were sparse (Table 2). The intermittent irrigation management, which is widely adopted for the rice fields in this district, evidently depopulates mosquito larvae and influences the species composition of larvae.

    The effects of an insect growth regulator, Dimilin : PH 60-40 (1-(4-chlorophenyl)-3-(2,6-difluorobenzoyl)urea), on early 4th instar larvae of four species of mosquitoes, Culex pipiens pallens, C. p. molestus, Aedes albopictus and Armigeres subalbatus, were studied in a laboratory, under 25℃, 70-80% RH, and the daily 16hr light and 8hr dark cycle. Serial dilutions were tested against group of 20 larvae which were placed in a 400ml plastic vessels containing 200ml of tap water and daily provision 10-20mg of the dry beer yeast. PH 60-40 inhibited adult emergence at concentrations around 0.75 to 1.5ppb almost completely. The EC-50 dosages were 0.72ppb in C. p. molestus, 0.47 in Ar. subalbatus, 0.30 in Ae. albopictus, and 0.18 in C. p. pallens respectively. The mortality at larval stage increased as the concentration of PH 60-40 increased and that the death occurred at the molting period of larvae, pupae and adults.
