<P>Osmia cornifrons is a cavity-nesting solitary species used as an apple pollinator in Korea. To elucidate the developmental characteristics of O. cornifrons, we investigated its development from the egg to adulthood, including a dormant prepupal phase and mating through indoor rearing (25 degrees C, 65% R.H.). The egg durations of the female and male bees were 3.6 +/- 0.8 days and 3.1 +/- 1.3 days, respectively. During larval development, the head widths of the 1st to 5th instars ranged from 0.7 +/- 0.1 mm to 1.3 +/- 0.1 mm. The peak of the growth in head width was the 2nd instar. The larval lengths ranged from 3.7 +/- 0.6 mm to 13.6 +/- 1.3 mm. The peak of growth was the 4th instar. The larval weights ranged from 4.5 +/- 1.2 mg to 78.3 +/- 16.1 mg. The peak of growth was the 3rd instars. The total larval durations of from the 1st to 5th instars for the females and males were 14.0 +/- 6.0 days and 13.2 +/- 5.8 days, respectively. The spinning durations of the females and males were 22 0.7 days and 2.3 +/- 0.8 days, the prepupation durations were 55.5 +/- 5.9 days and 55.8 +/- 2.9 days, and the pupation durations were 26.4 +/- 2.1 days and 25.3 +/- 2.3 days, respectively. The average longevity of the female adults and male adults was 21.8 +/- 8.7 days and 24.4 +/- 12.4 days, respectively. The total duration of from the egg to an adult bee of the O. cornifrons females and males was 1235 days and 124.1 days, respectively. Mating consisted of the three following phases: the precopulatory (courtship and attempting copulation), copulation and postcopulatory phases. The mating times of the precopulatory, copulation and postcopulatory phases were 159.6 +/- 288.9, 8.4 +/- 7.1, 12.9 +/- 4.5, and 198.8 +/- 69.8 s.

<P>Phoresy is one of the dispersal mechanisms of wingless microarthropods such as mites attached on the winged host. Mites associated with two scarabaeid beetles, Copris ochus and C. tripartitus (Coleoptera: Scarabaeidae) were collected from the ex-situ conservation site in Heongseong, Gangwon province in Korea. Among them, four species Copriphis hastatellus Berlese, 1910 (Eviphididae); Holostaspella scatophila Takaku, 1994 (Macrochelidae); Macrocheles japonicus Evans and Hyatt, 1963 (Macrochelidae); and Onchodellus siculus Berlese, 1892 (Pachylaelapidae) were recorded for the first time in Korea. Also, Parasitus consanguineus Oudemans and Voigts (Parasitidae) was previously recorded from the specimen in northern part of Korea in 1904, but since then no record has been made for a century. This is the second observation of this species over 100 years in the Korean peninsula. Description of this species is presented for comparison with the original description. Further discussion explored the relationship between the mites and dung beetles, and possible implication for the conservation of the endangered species.

The transition of noteworthy rice diseases and their control in Korea
Park J. S. Korean Society of Applied Entomology 1965 한국식물보호학회지 Vol.4 No.-
In Korea the most important plant industry is the rice-growing but she has not yet attained self-sufficiency with regard to rice which is the basic food of Korean. In the past, various measures of increasing rice production have been tried with some success but the increasing rate of did not show the sufficient result. Judging from experiences, disease control may be the most important factor which has influence on increasing of rice production in Korea. During the past 60 years three periods divided by the transition of rice diseases were noted, and especially the recent transition attracted much attention . That is, sheath blight and stripe which were minor diseases in the past have promptly spread all over the country and caused heavy losses to rice plant, and also local outbreak of bacterial leaf blight and dwarf were noticed. Various environmental factors are related to such transition of rice disease. Above all, cultivated varieties susceptible to these diseases, increase of application of nitrogenous fertilizer, earlier transplanting and density of transplanting are considered to be lucre closely related to the development of these diseases and successive development of blast. On the other hand. application of forage fungicides such as organic mercury compounds specific to blast contributed to reduce prevalent area if blast in spite of wide spread of susceptible varieties and increase of application of nitrogenous fertilizer. These facts were confirmed by Korean investigators At the present which various diseases to control coexist in the same region, no one variety resistant to all of these diseases is provided and cultural practices for the control of these diseases often do not produce sufficient yield of rice. it is emphasized that a role of pesticides is very great.

The South Korean hermit beetle has previously been identified as Osmoderma opicum, which is distributed in Japan. Because of its rarity, this species is classified as an endangered species. To date, however, the identity of this species in South Korea has not been conclusively confirmed. To assess the taxonomic status of the hermit beetle occurring in South Korea, we performed a comparative study with the beetle's Eurasian congeners, based on morphological examination and molecular analysis using COI gene sequences. The results clearly showed that the South Korean hermit beetle is identical to Osmoderma caeleste, which has been described from the Russian Far East. Therefore, we suggest that the taxonomic identity of the South Korean hermit beetle is O. caeleste.
Variation in Sex Pheromone Composition of a Few Selected Lepidopteran Species
Boo, Kyung-Saeng Korean Society of Applied Entomology 1998 Journal of Asia-Pacific Entomology Vol.1 No.1
Composition of insect sex pheromone is not always constant for any particular species. It may be different depending on the geographical area in the distribution of a species, as can be seen in the case of the European corn borer moth, Ostrinia nubilalis (Pyralidae). During the course of examining sex pheromone compositions of several lepidopteran species damaging agricultural and horticultural crops in South Korea, some subtle or apparent differences were noticed in sex pheromone compositions of Korean population belonging to those same species distributed in her neighboring countries. The oriental tobacco budworm moth, Helicoverpa assulta(Noctuidae), in Korea prefers the blend of 100 : 5 between(Z)-9-hexadecenal and (Z)-11-hexadecenal, while Thailand population responds best to 100 : 13 and Chinese population to wider blends from 100 : 2 to 100 : 20. Among lepidopteran insect pests on apples and apple tree leaves, the oriental fruit moth, Grapholita molesta(Tortricidae), showed almost no difference from one region to another. Korean population responded best to the blend of 100 : 5, with other populations to 100 : 6~100 : 9 between (Z)-8-dodecen-1-ol acetate and (E)-8-dodecen-1-ol acetate. Onthe other hand, the peach fruit moth, Carposina sasakii(C. niponensis) (Carposinidae), males were attracted best to a single component, (Z)-7-eicosen-11-one in the case of Korean population, in contrast to Japanese population which was shown to be preferentially attracted to the mixture of the (Z)-7-eicosen-11-one and (Z)-7-nonadecen-11-one at the ratio of 100 : 5. The yellow peach moth, Dichocrocis pundtiferalis(Pyralidae), seems to consist of two different populations in the northeastern Asia region, with one group resonding to the blend of 100 : 8~100 : 11 between (E)-10-hexadecenal and (Z)-10-hexadecenal and the other to tat of 100 : 43. The first group was found in Japan ad China and the second in Korea and also China. Korean population of the apple leaf miner, Phyllonorycter ringoniella(Gracillariidae), was best attracted to the blend of 100 : 150 between (Z)-10-tetradecen-1-ol acetate and (E, Z)-4, 10-tetradecen-1-ol acetate, while Japanese and Chinese popilations to the blends of 100 : 10~30 and 100 : 43~67, respectively. Furthermore, Korean Adoxophyes(Tortricidae) seemed to be a totally different species from Japanese Adoxophyes sp., or Adoxophyes orana fasciata, when viewed in terms of their pheromone composition.

Revision of the Fauna of Korean Spiders (Arachnida: Araneae)
Namkung, Joon,Kim, Seung-Tae,Lee, Joon-Ho Korean Society of Applied Entomology 2000 INSECTA KOREANA Vol.17 No.4
A list of Korean spiders was revised, including 46 families 225 genera 622 species which were reported by December 1999. Of these 61 added species and 37 alterated scientific names were supplemented, and 3 species, which have been reported since June 1994, were newly synonymized. The spider fauna of Korea is composed of 12 Cosmopolitan, 34 Holarctic, 66 Palearctic and 136 Korean endemic species. The spider fauna of Korea has much more similarity with Japanese spider fauna than with those of other countries.
A Study on the Community of Xylophagous Beetles in Korean White Pine, Pinus koraiensis, Forests

2007년에 잣나무림에서 하늘소과, 바구미과, 나무좀아과에 속하는 천공성 딱정벌레 군집을 말레이즈 트랩을 활용하여 조사하였다. 하늘소류 15종 184 개체, 바구미류 17종 185개체, 6종 1,246개체의 총 1,615개체 천공성 딱정벌레가 채집되었고 우점종은 왕녹나무좀이었다. 개체수에 따라 순위를 매겼을 때, 잣나무림에서 천공성 해충과 나무좀류 군집은 나무좀아과의 한 종에 의해 우점되어 생물다양성이 낮은 것으로 나타났다. 잣나무림에서 간벌은 나무좀과 암브로시아좀류의 풍부도에 영향을 미쳐 특정 임분에서의 개체군들은 간벌 1년 후 밀도가 증가했으나 그 후 감소하였다. The community of xylophagous beetles belonging to Cerambycidae, Curculionidae and Scolytinae in Korean white pine, Pinus koraiensis Siebold & Zuccarini, forests was surveyed using Malaise traps in 2007. A total of 1,615 xylophagous beetles were collected, including 184 cerambycids from 15 species, 185 curculionids from 17 species, and 1,246 scolytid beetles from 6 species, of which the dominant species was the ambrosia beetle Xyleborus mutilatus Blandford. Ranked by order of population size, the wood-boring and bark beetle community in Korean white pine showed high dominance by one species of Scolytinae, suggesting the community had low biological diversity. Thinning in Korean white pine forests influenced on the abundance of bark and ambrosia beetles, whose populations in particular stands increased 1 year after thinning, and then decreased the following year.
