  • Bumblebees, more efficient than honeybees, provide important services for pollination especially in tomato, pepper, cucumber, strawberries and other crops grown under tunnel farming or glasshouse conditions to yield maximization. These bees require pollen and nectar to meet their dietary needs and maintain their colony structure, development and reproduction. Keeping in view their economic importance, the effect of five concentrations of sugar and honey solutions (1:1, 1:1.5, 1:2, 2:1,1.5:1) each as alternative to nectar were used to observe their effect on life history parameters of Bombus terrestris. The 1:1 ratio of sugar solution was found most effective followed by 1.5:1, 1:1.5, 1:2 and 2:1 and also more effective of all five concentrations of honey solutions on all three stages of colony development i.e., at colony initiation, colony development and colony maturation stages. At colony initiation stage, early pre-oviposition period ($6.40{\pm}0.97$ days), early emergence of first worker in the first batch ($25.40{\pm}1.21$ days) and maximum numbers of workers ($6.20{\pm}0.24$) emergence in the first batch were observed at 1:1 ratio of sugar solution. Colonies reared on 1:1 ratio of sugar solution reached earlier ($52.13{\pm}1.28$ days) at colony foundation stage with minimum mortality ($3.27{\pm}0.54$ workers). At colony maturation stage, maximum numbers of workers, sexual (males, queens) and maximum mother queen longevity was observed at the same 1:1 ratio of sugar solution. It can be suggested from present study that sugar solution as alternative of nectar at 1:1 ratio was better than other sugar concentration levels and also from those of honey solution.

  • Morphological changes of flowers and insect visitors were observed to investigate pollinator of Caesalpinia decapetala. The flowers of C. decapetala are protandrous. Functionally, the flower is changed from male to female. As a male, pollen grain is released after anther dehisced while style is immature. After completed pollen grain release, the style starts to lengthen. It helps the stigma to easily touch the carpenter bee's thorax covered with pollen grain. At this time, flower functions as a female. The majority of taxa and individuals observed were Hymenoptera. The most frequent visitor was the Xylocopa appendiculata circumvolans, carpenter bee. Carpenter bees exhibited only typical pollinator behavior among flower visitors, with touching reproductive organs and seeking nectar at the same time. The pollination behavior is as follows. Soon after carpenter bees perceived guide mark, they foraged rightward and grasped style and stamens with legs and they inserted proboscis into standard petal to seek nectar. With this behavior, the pollen grains of the male flower transfer to the ventral thorax of the carpenter bee. As the carpenter bee moves to another female flower, the deposited pollen grains are delivered to the stigma.

  • An effective pollinator was investigated based on visiting insects to confirm the pollination mechanism of Impatiens furcillata Hemsl. (cheo-jin-mul-bong-seon), an annual herb that is also a species endemic to Korea that has hardly been studied in relation to pollination ecology. The insects that visited the group of I. furcillata studied here consisted of four orders, 11 families, and 16 species; Hymenoptera had seven species (43.8%), Lepidoptera had four (25.0%), Diptera four (25.0%), and Hemiptera one (6.2%). Visiting insects were divided into those that took only nectar, those that took nectar and pollen, and those that took neither. Insects that are effective for pollination are judged considering the length and body type of their mouth parts, and Amegilla florea Smith (huin-jul-beol) is judged to be the most effective pollinator in the survey area. As a result of observing pollination behavior, when visiting a flower, A. florea, which extended its glossa, approached the front, landed on a wing petal of I. furcillata, crawled into the flower tube, and then backed up and reversed its steps, with pollen adhered to its back. The findings here present basic information about species biology related to both I. furcillata and A. florea.

  • 조선 개국 후 유교적 가치관으로 성장한 통치 계급에게 불교 의례는 이른바 '위험한 축제'로 인식되었다. 의례는 출생에서 죽음에 이르는 삶의 중요한 전환점에서 다음 단계로의 이행을 도왔고, 제의를 통해 공동체의 결속을 강하게 했다. 의례 공간에는 도량을 신비로운 공간으로 변화시키는 다양한 공양구와 기물이 장엄되고 범음구와 범패가 어우러졌다. 그 중에서도 불교 회화는 기층민에게 강한 효력을 지닌 시각 매체로 적극 활용되었다. 생사의 인과응보를 담은 <시왕도>의 사례에서 볼 수 있듯이 의식이 마련된 도량에 불화를 헌괘하고 이를 생생하게 설명해주는 '관청(觀聽)'에 대한 수요로 불화의 기능은 더욱 확대되었다. 천도 의례 장면을 담은 <감로도>에는 왕실과 종친의 모습이 강조되어 표현되었다. 중국의 수륙화에서 이 도상은 수륙재에 봉청(奉請)하는 존귀한 대상 중 한 그룹이었으나 16세기 <감로도>에는 왕실의 후원을 상징하며 국행 수륙재의 역사성과 전통을 입증하는 존재로 도해된다. 왕실 후원은 불교 의례에 대한 사회적 공인과 같았고, 이러한 메시지를 드러내고 싶은 흔적이 <감로도>에 남아있다. 의례에 대한 위정자(爲政者)들의 경계는 표면적으로는 군중이 참여하는 의례 공간에 승속(僧俗), 남녀, 신분의 귀천(貴賤)이 함께 어우러지기에 예의가 무너지고 풍기가 문란해질 것이라는 우려였다. 또한 일상으로부터의 일탈, 금기로 부터의 해방이라는 축제의 요소와도 밀접한 관련이 있다. 시각 매체는 특별한 힘을 지니고 있다고 인식되었기에 그 힘을 이용하고자 하는 측과 위험성을 우려하는 시선이 공존했다. 실록(實錄)의 기록에서 위험성을 강조하며 불화를 불태우고 불화를 그린 자를 잡아오도록 하는 일련의 조치나, 도성이 텅 비도록 군중들이 모여든 기록은 역설적이게도 불교 의례가 반드시 참여해야 하는 축제의 장으로 인식됐음을 반증한다. 불교 의례는 생의 순환 단계에서 유교가 대체할 수 없는 종교적 기능을 지니고 있기에 쉽게 사라질 수 없었고, 공동체를 통합하는 축제의 요소는 더욱 강화되었다. 조선 후기 <감로도>에는 17세기부터 본격화되는 사당패나 연희패가 도해되고 의례의 현장감이 생생하게 반영되었다. 불행한 죽음을 위로하던 불교 의식은 해마다 일정한 시기에 마련되어 일상의 고단함을 털고 휴식을 취할 수 있는 축제의 장으로 자리 잡았다. 유교 국가의 정책적 탄압에 '위험한 축제'로 인식되던 불교 의례가 정례적인 세시풍속이자 공동체의 축제로 수용되는 과정을 불교 회화에 재현된 시선의 변화에서 확인할 수 있다.

  • The objectives of this study were to select early, late, and abundant flowering trees of black locust from domesticated and introduced cultivars, and prediction of flowering period by calculation of accumulated temperature in spring. Four cultivars (Debreceni-2, Pusztavacs, Jaszkiseri, and Rozsaszin AC) from Hungary and a cultivar from Beijing, China, were introduced, propagated by seed and planted in a seed orchard. For domesticated black locust, 63 cultivars from 10 locations throughout the country were selected and propagated by root cutting. Criteria for selection of domesticated cultivars were abundant flowering, long flowering period, or abundant nectar production with, if possible, straight stems. Accumulated temperature was calculated from data of a nearby weather station by accumulating daily maximum temperature minus 5 degree Celsius from January 1 up to the date reaching 880 degrees. Daily mean temperature was also used to calculate accumulated temperature up to the date reaching 450 degrees. The percentages of two-year and three-year-old flowering trees propagated by root cutting were higher than that of trees propagated by seeds, while four-year-old trees all flowered regardless of propagation methods. Among the domesticated cultivars, all the cultivars from Ganghwa showed abundant flowering with highest nectar production of 6.5 ul per flower, which was 100% more than other domesticated cultivars and 50% more than Debreceni-2 cultivar with highest nectar production among the introduced cultivars from Hungary. At the end of the eight years of observations, two trees of Debreceni-2 cultivars and a tree from Beijing, China were selected for early flowering trees which flowered 2 to 3 days earlier than average trees, while a tree of Debeceni-2 and three trees from Bejing were selected for late flowering trees which flowered 2 to 3 days later than average trees. It is possible to extend the flowering period of black locust by 4 to 6 days by planting early and late flowering cultivars together. Abundant flowering trees were unable to be selected due to severe damages by leaf gall midges which killed many trees and reduced the crown size of the remaining trees in the seed orchard, and which were first found in Korea in 2001 and now damaging most of the black locust forests in Korea. The prediction of flowering period by accumulated temperature indicated that black locust flowered to a peak when accumulated daily maximum temperature reached 880 degrees Celsius, and when daily mean temperature reached 450 degrees.

  • The purpose of this study is concerned with identification of floral type of commercially available honeys and pollen loads. Ikuse's technique was applied to identify the pollen species of honey and pollen loads. Among six kinds of commercially available honeys in Taegu, Korea i.e. Robinia Honey, Brassica Honey, Castanea Honey, Rhododendron Honey, Lespedeza Honey and Multipant Honey, all honeys contained pollens, which were coincident with their trade names given by the apirists, except Lespedeza Honey. The trade name of imported honeys were not given by the plant, from which pollen material and nectar were collected. Among four kinds of these products, pollen was not identified in Clover Honey. A spectrum of honey products added by pollen loads was, of course, wider than simple honey products. The pollen load showed spectrum of pollens including not only those which are specialized for wind pollination, eq. Pinus species and Gramineae, but also contained for insect pollination, eq. rose and leguminous plants.

  • Metcalfa pruinosa was considered to be a very harmful invasive species, due to its high species density in nature and wide range of its host plants. M. pruinosa was distributed in 28 sites among 143 sites. M. pruinosa has wide range and diverse host plants of 52 families 110 species including crop, fruits and forest trees. At present, the identified host plant of M. pruinosa are composed of 62 families and 145 species in total since their first appearance was reported. M. pruinosa was found in roadside 46.7%, followed by forests 33.3% and orchard 20%. Nymphs and adults cause damage to crop and orchard by sucking juice, outbreak of fungi through secretion of wax, and reduction of plant assimilation due to the nectar of nymphs. Also, it reduces the merchantable quality of fruits and thus causes economic damage. It is judged that M. pruinosa has been moved along major road via the traffic vehicles.
