ジャーナル フリーTransovarial transmission of Rickettsia tsutsugamushi (Rt) was experimentally demonstrated after establishment of infected laboratory colonies of Leptotrombidium deliense, L. fletcheri, L. arenicola and L. pallidum. Even if Rt is acquired by uninfected trombiculid larvae while feeding on infected rodents, it is not transmitted to progeny of the trombiculids. From these observations, trombiculid mites are considered to be the reservoirs as well as the vectors of Rt. Transovarial and filial infection rates were generally about 100%, but infected female produce largely uninfected offspring in a few cases. The adults of infected colonie of 3 species other than L. pallidum were mostly female, and the sex ratio in the infected L. fletcheri seemed to be controlled by Rt. In the adult stage of L. pallidum individuals, although Rt was seen in all the organs and tissues, it was distributed most densely in the salivary gland and ovary. Because the density of Rt was markedly different among cells in the same organ, it is considered that Rt does not transfer from one cell to another in trombiculids. Rt was found in many cells in the early stages of spermiogenesis, but was excluded from cytoplasm of these cells during the maturation process, resulting in the production of Rt-free mature sperms and spermatophores in the infected male trombiculid.抄録全体を表示PDF形式でダウンロード (1467K) -

ジャーナル フリーA questionnaire study was done in June and August, 1987,in Saga City, Japan, to know the frequency of mosquito bites, prevalence and effects of anti-mosquito measures, and citizens' view on mosquito problems. Mean numbers of bites were 0.99 (June) and 0.95 (August) per day per person staying at home throughout the day, with maximums of 9 (June) and 14 (August). Three quarters of those persons received 1 or less bite per day. More (64%) bites were received during the daytime (sunrise to sunset). Of daytime bites, 60% were outdoors, whereas 70% were indoors at night. The number of bites outside home (offices, schools and so on) was much fewer than that at home. Seventy percent of houses were equipped with screens at all windows. The most popular anti-mosquito measure was electric-heating insecticide mats followed by insecticide sprays and mosquito coils, whereas mosquito nets were used in only 15% of houses. Window screens reduced the number of indoor bites, whereas the frequency of use of antimosquito measures positively correlated with the number of indoor bites, suggesting that insecticides were used after mosquito bites rather than a preventive measure. Persons receiving more mosquito bites had stronger attitudes toward mosquito control by the public service. More than a half of persons receiving 2 or more bites per day considered that the mosquito problem was intolerable and the control is necessary. As a whole, 42% of persons regarded the mosquito problem tolerable, whereas 41% regarded it intolerable, with only 3% who regarded mosquito problems negligible (the rest did not give answer to this inquiry).抄録全体を表示PDF形式でダウンロード (1094K) -

ジャーナル フリーThe influence of feeding histories on the food selection of the German cockroach is reported. Adult cockroaches were fed with one of three types of foods, rice bran, dried fruit (apricot), and a dried meat product (dog food jerky), for 18,10,or 5 days before 2 days of starvation. They were then allowed to feed freely on two of the three, including the food experienced just before. The cockroaches usually preferred the other food to the experienced, or more liked the other than before. Nymphs also showed similar responses.抄録全体を表示PDF形式でダウンロード (691K) -

ジャーナル フリーフタトゲチマダニの幼虫, 若虫, 成虫の宿主への寄生と発育を25℃一定で, 日長条件(10L-14D, 16L-8D)を変えて観察した。飽血幼虫および飽血若虫の発育は, 卵期から長日条件(16L-8D)で飼育しても, 短日条件(10L-14D)で飼育しても, ほとんど変わらなかった。しかし, 未吸血若虫および未吸血成虫の宿主への寄生は卵期から短日条件で飼育した場合, 著しく阻害された。これらの結果は, フタトゲチマダニの未吸血若虫と未吸血成虫は, 短日条件で育った場合, 休眠に入るが, 飽血幼虫と飽血若虫は, 日長条件にかかわらず, 休眠に入らないことを示唆する。埼玉県において, 秋に若虫が出現しないのは, 秋の短日条件下で発育した若虫が休眠に入るためかもしれない。しかし, 秋における成虫の不活発な活動は, 成虫が春から夏の長日条件下で発育することから, 休眠によって説明できない。抄録全体を表示PDF形式でダウンロード (429K) -

ジャーナル フリーA great number of stink bugs migrated and invaded into the indoor for hibernation, and became a nuisance in an elementary school in Hokkaido every year. We examined the effects of soundproof double windows and application of concentrated cyphenothrin to the window frames on the control of bugs invasion into the school building. The soundproof window had preventive effect on the invasion, number of bugs gotten in the rooms decreased to one-sixth comparing with conventional double windows. Residual treatment of cyphenothrin to the window frames enhanced the effectiveness.抄録全体を表示PDF形式でダウンロード (570K) -

ジャーナル フリーSurveys of domestic mites were carried out in livingrooms and bedrooms of 20 concrete-built apartments in and around Nagoya City, from September 1983 to June 1984 at about 3-month intervals. Multiple regression technique was applied to elucidate the influence of housing conditions on the prevalence of mites. Major housing conditions were selected by backward elimination method. The annual mean densities of Dermatophagoides pteronyssinus were positively correlated with family size and air-conditioning and inversely with age of house, floor level, and house-cleaning frequency. There was good agreement between the mite densities observed and estimated by the multiple regression equation. While similar factors were detected for the total number of mites and Cheyletidae, no significant factor was detected for D. farinae. Haplochthonius simplex had positive correlation with the number of rooms and air-conditioning, and negative correlation with age of house, floor level, and house-cleaning frequency. No positive factor was detected for Cosmochthonius reticulatus, which had negative correlation with floor level. Working housewife, air-conditioning and the number of rooms were positive factors for Tarsonemidae, Glycyphagidae and Acaridae, respectively, and age of house, cleaning frequency, and floor level were negative factors for most of the mites, although the extent of influence of these factors considerably varied by mite species. The number of mite species correlated positively with the number of rooms, air-conditioning, and flooring scores, and inversely with age of house, floor level, and house-cleaning frequency, whereas Simpson's indexes of diversity had positive correlation with air-conditioning, and negative correlation with the number of rooms and flooring scores. These results suggested that the difference in mite prevalence in homes is mostly due to the interrelationship between the biological characteristics of mites and degree of humidity in homes largely influenced by household activities, dwelling space and floor level, i.e., distance from the ground surface.抄録全体を表示PDF形式でダウンロード (1556K) -

ジャーナル フリーThe Height of attachment to host was investigated in two species of ticks, Haemaphysalis megaspinosa and Haemaphysalis longicornis, in the southern part of Chiba Prefecture from March to May in 1992 and 1993. Laboratory experiment showed the attaching H. longicornis adults fell off more easily than H. longicornis nymphs. We wore flannel clothes marked at intervals of 10cm to record the attachment height of ticks. We walked in the study site and collected ticks that attached to our clothes. H. megaspinosa was mostly collected. There was no significant difference between the height of attachment to man and the height of ticks remaining on plants. Though H. megaspinosa nymphs were collected at higher positions on plants than H. longicornis nymphs, there was no significant difference between them in the height of attachment.抄録全体を表示PDF形式でダウンロード (535K) -

ジャーナル フリーDuring the years 1993 to 1995,a total of 3,480 ticks were collected by flagging on vegetation and from field rodents in various sites spread throughout the mainland of Kagoshima Prefecture, Japan. These were identified as three genera and 11 species as follows : Amblyomma testudinarium, Haemaphysalis flava, H. formosensis, H. hystricis, H. kitaokai, H. longicornis, H. megaspinosa, H. sp., Ixodes nipponensis, I. ovatus and I. turdus. Of these species, H. formosensis, H. hystricis and H. sp. were newly recorded in this area. H. flava, H. formosensis and H. longicornis were the predominant species. In a review of the present and other previous reports, four genera and 16 species of ticks were summarized from the mainland of Kagoshima Prefecture. In L-929 cell culture, five strains of unknown spotted fever group rickettsiae were isolated from I. ovatus adults. In isolation of Borrelia spirochetes with BSK culture, two larval and one nymphal I. ovatus and one Apodemus speciosus mouse were positive for Borrelia japonica.抄録全体を表示PDF形式でダウンロード (1180K) -

ジャーナル フリーAcetophenone, a keton, was demonstrated to cause acute and delayed types of insecticidal and ovicidal activities against the mosquito, Culex quinquefasciatus Say, under laboratory conditions. At 0.05-10ppm, acetophenone induced cumulative (larvicidal+pupicidal+adulticidal) mortality in a concentration-activity manner. Delayed activity of acetophenone was detected in the F_1 progeny showing lower fecundity and significant larval mortality. Morphological aberrations were evident in the larvae, pupae and adults, i.e., larval shortening, larval-pupal intermediates and incomplete emergence of adults at 0.05-10ppm. Acetophenone also caused significant ovicidal activity at concentrations of 0.1-10ppm.抄録全体を表示PDF形式でダウンロード (359K) -
