Majority of asthma and atopic dermatitis are known to be spontaneously sensitive to house dust mite allergen. 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. So, It is more effective method keeping the house dust mites away than killing them. The use of plant-derived repellents has been considered as a promising alternative to chemical repellents. Eucalyptus is a diverse genus of flowering trees in the myrtle family, Myrtaceae. It has insect repellent properties and is an active ingredient in some commercial mosquito repellents. These studies were carried out to investigate repellent effects of Eucalyptus oil against house dust mites and compare lemongrass oil. Eucalyptus oil and lemongrass oil were exposed at different doses (0.2, 0.1, 0.05, 0.025, 0.0125, $0.00625{\mu}l/cm^2$) and different times (1, 3, 6 hours) on house dust mites. The most effective dose of Eucalyptus and lemongrass oils against house dust mites was $0.1{\mu}l/cm^2$ and $0.025{\mu}l/cm^2$. Each repellent effect(%) in most effective dose was 90.3% (Eucalyptus) and 80.8% (lemongrass).

Five hundrad and eight rats were caught in Shiheung-dong and Mt. Kwan-ak from 1986 to 1987 in this survey. Ectoparasites were got from these rats and classified. The results were as follows: 9,191 mites (16 genera, 30 species), 408 fleas (4 genera, 4 species), and 521 lice (3 genera, 5 species) were observed in this survey. In the residential area, Rattus norvesicus(71.74%) was dominant species and in Mt. Kwan-ak Apodemus agrarius(93.62%). In these areas, the mites belonging to suborder Mesostigmata were dominant (Laelaps nuttli, 52.61%; Ornithonyssus bacoti, 36.05%). In Mt. Kwan-ak, family Frombiculidae belonging to suborder Prostigmata were dominant (Leptotromibidium orientalis, 31.04%; Leptotrombidium palpalis, 30.00%). In this way, it was discovered that the difference between the two regions in dominant species was noticeable. As for the hosts parasitized by mites, L. nuttalli in R. norvegicus (54.85%), L. nuttalli in R. rattus (32.90%), and L. orientalis in A. agrarius (31.27%) were dominant species, respectively. In the mites parasitizing on A. agrarius in each altitude, the species were more varied as the region was lower and the dominant species were more concentrated as it was higher.

This report concerns with three species of eriophyid mites on Licium chinensis in Korea. Of them, the external morphology of Aceria tjyingi (Manson 1973) was observed with Scanning Electron Microscope. The author reviewed three species of Korean eryophid mites and suggests Korean names of Aceria kuko kishida, A. macrodonis Keifer, and A. tjyngi (Manson), respectively.

The author collected 2 species of spider mites from persimmon and citrus trees in Taegu and Chun Chon during the summer of 1961 and 1969. Tenuipalpus japonicus collected from persimmon trees and Panonychus citri collected from citrus trees in and from trifoliate orange trees. In 1958 and 1961 Dr. E. S. Lee recorded four phytophagous species, i.e. Panonychus ulmi, Tetranychus pacificus, Tetranychus urticae and Bryobia praetiosa.

We describe three feather mites recovered from a wood sandpiper Tringa glareola that was stored in a $-20^{\circ}C$ freezer at the Chungnam Wild Animal Rescue Center. These feather mites are reported for the first time in South Korea: Avenzoaria totani (Canestrini, 1978), Ingrassia veligera Oudemans, 1904 and Montchadskiana glareolae Dabert and Ehrnsberger, 1999. In this study, we provide morphological diagnoses and illustrations. Additionally, we provide partial sequences of the mitochondrial cytochrome c oxidase subunit I(COI) gene as molecular characteristics of three species.

Feather mites comprise two superfamilies(Analgoidea and Pterolichoidea) and are highly specialized ectosymbionts of birds. To date, this group contains more than 2,500 species worldwide. Fifty-five feather mite species have been reported in Korea, and only one species of genus Alloptes has been recorded from black-tailed godwit Limosa limosa. Three new records of feather mites from the L. limosa in Korea are added in this study: Avenzoaria punctata Gaud, 1972, Bregetovia limosae (Buchholz, 1869), and Montchadskiana buchholzi (Canestrini, 1878). The genus Bregetovia Dubinin, 1951 is also new report for this country. In this paper, we provide the morphological descriptions and illustrations based on the present specimens. Additionally, we determined partial sequences of the mitochondrial cytochrome c oxidase subunit I(COI) from three feather mites as DNA barcodes.

A total of 9,281 larval chigger mites were collected from small mammals captured at Hwaseong-gun, Gyeonggi-do (Province) (2,754 mites from 30 small mammals), Asan city, Chungcheongnam-do (3,358 mites from 48 mammals), and Jangseong-gun, Jeollanam-do (3,169 for 62 mammals) from April-November 2009 in the Republic of Korea (= Korea) and were identified to species. Leptotrombidium pallidum was the predominant species in Hwaseong (95.8%) and Asan (61.2%), while Leptotrombidium scutellare was the predominant species collected from Jangseong (80.1%). Overall, larval chigger mite indices decreased from April (27.3) to June (4.9), then increased in September (95.2) and to a high level in November (169.3). These data suggest that L. pallidum and L. scutellare are the primary vectors of scrub typhus throughout their range in Korea. While other species of larval chigger mites were also collected with some implications in the transmission of Orientia tsutsugamushi, they only accounted for 11.2% of all larval chigger mites collected from small mammals.

포식성 천적 O. kashmiricabenefica의 식식성 응애류 3종에 대한 포식량, 포식선호성 그리고 동족포식을 조사하였다. 성충의 일평균포식량은 먹이인 응애의 밀도와 온도가 높을수록 증가하였다. $25^{\circ}C$ 항온조건하에서 O. kashmirica benefica 성충의 일평균포식량은 귤응애, 점박이응애, 차응애 성충을 각각 21.9, 13.5, 14.1마리씩 포식하였다. 유충의 포식량은 영기가 증가할수록 많아져서, 1령, 2령, 3령 유충이 각각 2.8, 11.2, 25.4마리의 귤응애 성충을 포식하였다. O. kashmirica benefica 유충은 귤응애, 점박이응애, 차응애 성충을 유충기간(5일, $25^{\circ}C$)동안 각각 77.7, 61.3, 73.0마리씩 포식하였다. O. kashmirica benefica 유충과 성충은 글응애, 점박이응애, 차응애 중에서 특정한 종을 선호하는 경향은 없었으며, 먹이가 없을 때에도 동족포식 정도는 매우 낮았다.

Acarapis mites, including Acarapis woodi, Acarapis externus, and Acarapis dorsalis, are parasites of bees which can cause severe damage to the bee industry by destroying colonies and decreasing honey production. All 3 species are prevalent throughout many countries including UK, USA, Iran, Turkey, China, and Japan. Based on previous reports of Acarapis mites occurring in northeast Asia, including China and Japan, we investigated a survey of Acarapis mite infestations in honey bees in Korean apiaries. A total of 99 colonies of Apis mellifera were sampled from 5 provinces. The head and thorax of 20 bees from each colony were removed for DNA extraction. PCR assays were performed with 3 primer sets, including T, A, and K primers. Results indicated that 42.4% (42/99) of samples were Acarapis-positive by PCR assay which were sequenced to identify species. Each sequence showed 92.6-99.3% homology with reference sequences. Based on the homology, the number of colonies infected with A. dorsalis was 32 which showed the highest infection rate among the 3 species, while the number of colonies infected with A. externus and A. woodi was 9 and 1, respectively. However, none of the Acarapis mites were morphologically detected. This result could be explained that all apiaries in the survey used acaricides against bee mites such as Varroa destructor and Tropilaelaps clareae which also affect against Acarapis mites. Based on this study, it is highly probable that Acarapis mites as well as Varroa and Tropilaelaps could be prevalent in Korean apiaries.
