This survey was carried out in four areas in southern Korea from May 1983 through April 1986. A total of 1, 717 house rats was caught by trapping technique throughout the 4 areas. The total of 1, 535 trombiculid mites (4 genera, 7 species) was found only among Rattus norvegicus. Six species were observed in Seoul and Yangsuri areas, and 5 species in Seongnam area. No trombiculid mites were found in the rats caught in Inchon area. The highest infection rate of trombiculid mites (25%) was recorded in the rats caught in Seongnam area. And Leptotrombidium palpale was abundant species in general (detection rate; 72.8%) In seasonal variation, the hightes number of trombiculid population was observed from October through December in all the areas surveyed, and especially Euschongastia koreaensis apperaed more in autumn and winter than in any other season. The values of specie diversity and evenness of trombiculid mites found in Yangsuri were comparatively higher than those from the other areas.

The exposure to house dust mites is closely connected with allergic diseases such as atopic dermatitis, allergic rhinitis and asthma. Control of house dust mite populations has been principally achieved by using chemical insecticides. But the risk to human health would be a potential problem. Moreover, house dust mite remain as allergens even after death. Therefore, repelling the house dust mites is more effective method than killing them. The use of plant-derived repellents has been considered as a promising alternative to chemical repellents. Eucalyptus oils are regarded as safe compounds, there have been attempts to commercialize and market the insecticides/repellent products containing Eucalyptus oil as such or based upon them. For that reason, we experimented repellent activity against these mites using laundry detergent with Eucalyptus oil in this experiment. House dust mites (Dermatophagoides farinae and Dermatophagoides pteronyssinus) were exposed at different concentrations (4, 8, 16, $32{\mu}L/mL$) in fabric treated laundry detergent with Eucalyptus oil for 24 hours. The repellent effects (%) of laundry detergent with Eucalyptus oil exposed at 4, 8, 16, and $32{\mu}L/mL$ were 48.16%, 74.62%, 52.67%, and 44.47%, respectively. These results suggest that laundry detergent with Eucalyptus oil have potential effect to repel the house dust mites.

The majority parasitic bee mites of Thailand in genus Tropilaelaps are infesting colonies of native bees (Apis dorsata) and introduced bees (A. mellifera). The investigation aims to study morphological and genetic variation of Tropilaelaps mites infected different hosts. Adult mites were collected from honey bee brood throughout Thailand. Traditional and geometrical morphometrics were measured on photograph by using TPS program. Additional, COI gene variations were examined by PCR-RFLP and nucleotides sequencing. Tree of mites relationships were constructed by NJ and MP assumptions. Morphometric results indicated T. mercedesae were major species infesting on A. dorsata and A. mellifera. Mophological variation represented at anal and epigynial plate, which the shape of the anal plate apex margin has been key character to identify between T. mercedesae (bell to blunt shape) and T. koenigerum (pear shape). However, the discriminant analysis suggested that geometric results were potential to classify Thai Tropilaelaps populations from different hosts better than traditional morphometric. Otherwise, PCR-RFLP clearly detected the site of Dra I and Xba I digestion of Thai Tropilaelaps morphotypes. The COI sequences of T. koenigerum were founded infesting only A. dorsata in Thailand and four sequences that related to the Thai T. mercedesae morphotypes. The NJ and MP tree were clearly classified Thai Tropilaelaps species which were suggested both from morphological and molecular analysis. This information might be basically of taxonomic status, but this should have implication for controlling these mites in Thailand and other countries.

1993-1994년에 걸쳐 전국 10개 지역내 주택에서 수거한 집먼지내의 진드기류를 조사하였다. 집 먼지는 평소 가정주부가 사용하는 전기진공청소기내 횔터에 모아진 집먼지 중 10 g을 채취하여 wet sieving metrod 일부 보완하여 진드기류를 분리하였다 채집된 총 7,257개체의 진드기를 동정한 결과 4아목 18과 23속 23종을 확인하였는데 그 중 Rhyzoglyphus robini, Sancossania phwllophcgianus, Cheyletus trouessarti 및 Scheloribotes lotipes의 4종은 국내 미기록 종이었다 전국적으로 가장 널리 분포되어 있고 서식밀도가 높은 종은 nemntophago릴os Jnrinae(DF)로 전체의 65.3%였고 D. Pteronvssinus(DP)가 20.6% Twrophnsus putrescentiqe(TP)가 6.5%를 차지하였는데, 이들 3종이 함께 서식하는 가정은 62개 조사대상 중 24.6%였고. 2개종이 공존하는 가정은 48 1%. 한종만 서식하는 가정은 27.3%였다. DF가 우점 종인 가정은 59개 조사 가정 중 63.5% DP가 우점종인 가정은 29.6%였고 TP가 우점종인 가정은 6.9%였다. 지역적으로는 서울. 광주 인천 전주 정주 등지에서는 DF가 우세하였으나 영광 춘천. 부산 영도 등 대기습도가 비교적 높은(> 73% RH) 지역에서는 DP가 우세한 것으로 나타났다. 집먼지진드기의 서식밀도를 보면 집먼지 10g 중 1.000개체 이상인 가정이 2.9%. 500-999 개체의 가정이 4.3%. 100-499개체의 가정이 15.7%였고 99개체 이하의 밀도를 보인 가정이 70.0%를 차지하였으며 전혀 채집되지 않은 가정은 7.1%였다. 아파트와 단독주택. 건물면적 청소횟수. 가족수. 건축년수 등과 집먼지진드기 서식밀도간에는 상관관계를 보이지 않았다.

Asthma and allergic rhinitis due to outdoor spider mites are major health problems worldwide. The sensitization route to spider mites has not yet been well elucidated. We examined the microstructure of faecal pellets and silk of the two-spotted spider mite, Tetranychus urticae, using a field emission scanning electron microscope. Black and white pellets of the two-spotted spider mites faeces contain a large amount of plant pigment waste products. Black faecal pellets are strawberry-shaped. White faecal pellets are silken threads. These pellets are likely to be the source of allergens of relevant mites because desiccated faeces particles probably disintegrate and become incorporated into dust particles more readily than whole bodies or encased internal organs. We conclude that the importance of spider mites in respiratory allergy needs emphasis.

Purpose: The purpose of this study was to identify the indoor environment i.e. house type and age, ventilation method, use of bed & sofa, cockroach, ants, etc. on HDM (House dust mites), especially Der fI allergen. Method: Samples of dust from mattresses, pillows and the floor were collected by using a vacuum cleaner from April. 2000. The amount of Group I allergen(Der. fI) of HDM (house dust mites) were measured by two-site ELISA. Indoor Environmental characteristics were accessed by using questionnaires on 178 house wives living in the Seoul area. Results: The amount of HDM allergen (Der fI) was higher in sofa using house. There were higher concentrations of HDM allergen (Der fI) in sofas made from quilt material than for those that were made from leather. Homes that had pets like dogs living in them had higher concentrations of HDM allergen (Der fI) than without dogs. Conclusion: The photophobic mites thrive in dark. warm and humid environments; Items such as pillows. mattresses, box springs, blankets. carpets. and upholstered furniture should be considered ideal environments for the mite. Therefore, an indoor environmental control program should be carried out to avoid the HDM allergen.

This study was conducted to provide basic knowledge of effective environmental control of patients with allergic rhinitis during the period of July to December 1995. The subjects were consisted of 29 patients with allergic rhinitis. Each patient of nasal symptom scores assessed and dust samples drowned from their bedrooms twice for 1 month interval. The data. 58 samples were analyzed by using ANOVA. t-test and stepwise multiple regression. The results were as follows 1. Out of a total 52 dust samples $(89.7\%)$ were isolated house mites. Total 815mites/0.5gm dust were collected and identified the most prevalent house mites was Pyroglypidae mite with $81.1\%$ 2. The amount of house dust mites in the group of bedding laundry with hot water was significantly lower than that those of with cold water. 3. The nasal symptoms of the patients in the group of bedding laundry with hot water was significantly less than that those of with cold water. and also those of using large size bedroom was significantly lower than that those of using small size one. The nasal symptoms of the patients was closely associated with the washing water temperature. bedroom size. bedroom temperature. type of bedclothes, and frequency of cleanig room.
