ジャーナル フリーMosquito larval surveys were carried out on Pohnpei Island, Mokil Atoll and Pingelap Atoll, Pohnpei State, the Federated States of Micronesia in November 2007 and August 2010. On Pohnpei Island, a total of 1,161 larval mosquitoes belonging to six species were collected at 59 various natural and artificial habitats. They were identified as Aedes albopictus, Ae. hakansoni, Ae. oakleyi, Culex quiquefasciatus, Cx. maplei and Cx. annulirostris. Aedes albopictus was only collected in two habitats, a small plastic container and a tire. It may be notable that Ae. albopictus and Ae. oakleyi were newly reported in Pohnpei State. Aedes hakansoni was the predominant species. On Mokil Atoll, a total of 682 larval mosquitoes belonging to three species were collected at 49 habitats. They were identified as Ae. albopictus, Ae. marshallensis and Cx. quiquefasciatus. Aedes albopictus was collected in 20 habitats (40.8%) that were of small or medium size. Aedes marshallensis was also collected from small- and medium-sized habitats. On Pingelap Atoll, a total of 870 larval mosquitoes belonging to four species were collected from 46 habitats. They were identified as Ae. aegypti, Ae. marshallensis, Ae. vexans noctunus and Cx. quiquefasciatus. Among them, Ae. aegypti was the predominant species which was collected in 21 (45.7%) small to large habitats. Aedes marshallensis was also collected from a wide range of habitat sizes. Mokil Atoll and Pingelap Atoll are highly dengue-sensitive, because Ae. albopictus and Ae. aegypti were widely distributed on them. Efforts should be taken to reduce potential breeding sites for Aedes mosquitoes in these areas.抄録全体を表示PDF形式でダウンロード (233K) -

ジャーナル フリーマウスを麻酔して2群に分け，一群には二酸化塩素のスプレーを他の一群には水のスプレーを噴霧したのち，マラリア感染蚊自由に吸血させた．二酸化塩素をスプレーしたマウスに対しては101匹の蚊のうち6匹が吸血した (5.9%) だけで、マウスの感染は13頭中1頭のみ (7.7%) であった．水をスプレーしたマウスに対しては蚊88匹のうち42匹が吸血し (47.7%), マラリア感染は11頭中6頭 (54.5%) であった．二酸化塩素スプレー群は有意差をもって吸血率 (p<0.01)・マラリア感染率 (p<0.05) の低下が見られた．次に両端をメッシュで覆ったチューブの中に蚊を入れ，チューブの片方は空気のみを含むケージに，反対側は二酸化塩素を含むケージに差し込んで，蚊がどちらの側に偏在するか調べた．Anopheles stephensi, Aedes albopictusおよびCulex pipiens pallensの3種蚊とも0.03 ppm以上の二酸化塩素濃度において反対側（空気側）に偏在した．二酸化塩素は蚊に対する忌避作用があるといえた．抄録全体を表示PDF形式でダウンロード (233K) -

ジャーナル フリーExperiments exposing Aedes aegypti to winter conditions were conducted at Narita International Airport, Japan during December 2012 to March 2013 to evaluate the possible overwintering of the species. Four and 2 study sites were selected inside and outside the terminal buildings, respectively, and air temperature and relative humidity were recorded hourly at each site. Eggs were placed for 91 or 63 days at each study site, respectively, and the hatching rate and adult emergence rate were examined in March 2013. Under outdoor conditions (daily average of 5.2°C and 57.3%R.H.), 6% of the exposed eggs hatched but no adults emerged. Eggs exposed to indoor conditions (daily average of 14.3–19.4°C and 34.3–36.8%R.H.) showed 2 to 8% adult emergence. Exposure experiments using larvae were conducted for 1 week every month, and their development and survival rate were observed. Under outdoor conditions in January and February 2013, all the exposed larvae died within a week. Larvae placed inside the terminal building developed well and the threshold temperature for larval development was estimated as 10.6°C and 11.6°C for hatched larvae and 4-day-old larvae, respectively.抄録全体を表示PDF形式でダウンロード (443K) -

ジャーナル フリーSeasonal prevalence and daily activities of tabanid flies were surveyed fortnightly during the period of July 7th to September 15th in 2011 at the Motoyama pasture in Esashi, Hokkaido and during the period of July 27th to September 5th in 2012 at the Minamisawa pasture in Horonobe, Hokkaido. The CO2 lured NZI traps were used to capture the flies in these pastures. A total of 9,478 individuals of flies including 5 genera and 12 species were captured at Esashi and 1,294 individuals including 5 genera and 8 species were captured at Horonobe. In Esashi, Tabanus nipponicus was captured as the most predominant species, and was followed by T. rufidens and in Horonobe, T. nipponicus and Haematopota tristis were predominant species. The seasonal prevalence curve of captured number of T. nipponicus showed a peak at mid-July and that of T. rufidens showed a peak at mid-August in Esashi, and that of Hae. tristis showed a peak at early-August and that of T. nipponicus showed a peak of mid-August in Horonobe. From the results obtained in this survey, the measures against these flies should be taken from July to late-August at both pastures.抄録全体を表示PDF形式でダウンロード (434K)

ジャーナル フリーJapanese cockroach Periplaneta japonica (Stoll) was collected at a Japanese common wooden house and in a shrine of Hokkaido Jingu, and Maruyama Park in Sapporo city. In Hokkaido, this species was recorded only from the coastal area of the southern parts and Otaru city up to present. Therefore, these are the new records of this species from the landlocked city in Hokkaido, and the new record of invasion to a highly airtight house of Hokkaido.抄録全体を表示PDF形式でダウンロード (2864K)

ジャーナル フリーCentipedes are nocturnally active arthropods, which mainly live in fields but often invade indoors. Centipede bites are common, but it has been reported that approximately 1% of centipede bites lead to anaphylactic symptoms. However, in Japan, few cases of anaphylactic symptoms after centipede bites have been reported. We report here a case of anaphylactic shock after a centipede bite, and the characteristics of 16 patients with centipede bites at Himeshima National Health Insurance Clinic in Himeshima village, Oita, Japan, between June 2010 and May 2013.
A 59-year-old Japanese man had experienced a centipede bite 2 years previously. He again experienced a centipede bite while asleep, and his body developed a red flare, his consciousness became unclear, and his blood pressure was low. We diagnosed him with anaphylactic shock, and saved his life by appropriate treatment.
Considering the 16 patients with centipede bites at Himeshima National Health Insurance Clinic between June 2010 and May 2013 and some case reports about centipede bites, we think that the main risks of shock due to centipede bites are anaphylactic reaction, repeated exposure to centipede poison and bee poison, and injuries to the head and face. Appropriate therapies for cases with slight injuries due to centipede bite are pain control and steroid external medication including antibacterial drugs.抄録全体を表示PDF形式でダウンロード (1170K)
