As a series of studies to develop pest management system for sweet persimmon production matched with the quarantine criterion of sweet persimmon-imported county, a survey was conducted by questionnaire on pest management practice and scheme of increasing income in sweet persimmon farms in Korea. Above 80% of sweet persimmon farmers was over fifties in age. The greatest limiting factor for sweet persimmon production was thought to be disease by the farmers. Percentage of farmers who answered that the most important pest is anthracnose cause by Gloeosporium kaki, and stink bugs was 64.6% and 73.5%, respectively. In particular, the farmers did not consider Dichocrocis punctiferalis, a main targer insect for quarantine in USA, as serious problem. Obtaining information on pest management practice or decision-making on both selection of pesticide and time of pesticide application depended highly on their own experience with the highest proportion. Eight to nine times of pesticide applications a year was highest among farms with 56.6%. More than 80% of farmers recorded the diary of pesticide application. farmers considered increasing cost for pest management as the greatest problem with 35.4% in proportion, and 34.5% of farmers pointed out that increase in export is essential for increasing farm income with highest proportion.

To investigate the actual condition of orchard and pest management of persimmon orchards, a questionnaire was ask to the farmers in major cultivated areas of persimmon and dried persimmon, Sangju, Gyeongbuk in 2007 and 2008. 91.1% of persimmon farmers was over fifties in age and 94.7% of persimmon farmers was cultivated 'Sangjudungshi'. The greatest limiting factor for persimmon production was thought to be disease by the 58.4% of persimmon farmers and the most serious disease was anthracnose by Colletotrichum gloeosporioides. 60.2% of them was answered that the most serious insect pest was scale insects. Obtaining of knowledge or information on pest management depended own experience (37.2%) and 48.7% of answered farmers was decision-marking of pesticides depending on agrochemical market. 54% of persimmon farmers was applied pesticides $3{\sim}5$ times per year. Just 17.7% of them recorded the diary of pesticide application. The greatest problem for management of pest in persimmon orchard was lack of knowledge of pest (60.2%) and farmers considered increasing cost for pest management as the greatest problem with 52.2% in proportion. 66.4% of farmers was mixed cultivation with soybean (37.7%) and hot pepper (26.1%) in persimmon orchard. 44.2% among answered farmers mixed cultivation of persimmon with production of dried persimmon and 54.5% of farmers considered lack of labor as the greatest problem in production of dried persimmon.

Landscape composition and structure are important factors determining biological diversity including pests and natural enemires in agricultural ecosystem. This study was conducted to indentify effect of landscape composition on occurrence of lepidopteran pest population in Geochang, Gyoungdnam. For this, orchard characteristics and management practices were surveyed in 80 conventional apple orchards in Geochang, Korea, along with the monitoring of pest population densities. The landscape features of each surveyed orchard also obtained by extracting information from the public-service map. Grapholita molesta was the most dominat and damaging pest followed by Phyllonorycter ringoniella and Carposina sasakii in trap catches. Adoxophyes paraorana occurrences were low. Farmers spray insecticides and fungicides ap. 12.4 times per year respectively while acaricides were sprayed 2.4 times. Major landscape features such as surrounding apple orchard or paddy field did not influence the pest populations but presence of plum, peach, wild peach, graph, and even abandoned orchards significantly resulted in higher pest population mostly on G. molesta. C. sasakii population was higher in orchards with grape, peach, and P. ringoniella with peach, grape, abandoned orchards and jujube. Results highlight the need of landscape management not only for the rural amenity but also for increasing functional diversity of agroecosystem as well as reducing pest population.

In this study, insect pest communities and major insect pest species were investigated and compared among 30 cultivars of Hibiscus syriacus. Insects on H. syriacus were observed with the naked eye over 3 years (from 2018 to 2020) in Busan and Suwon. Except for Aphis gossypii (79,059 and 23,654 individuals in Busan and Suwon, respectively), 20 species (1,147 individuals) and 31 species (2,240 individuals) were found in Busan and Suwon, respectively. The number of insect pest species and individuals did not differ among H. syriacus cultivars, but there were differences according to study locations. The dominant insect pest species were A. gossypii, Rehimena surusalis, Rusicada privata, Halyomorpha halys, Haritalodes derogata, Dolycoris baccarum, and Plautia stali; the number of individuals in dominant species differed according to study location and year but not among H. syriacus cultivars. In summary, insect pest communities did not differ among 30 H. syriacus cultivars, but the matrix of surrounding environments where H. syriacus are planted may be more important.

Continuing education for professionals is the most basic requirement for continuous professional development. The enhancement of the professionalism of librarians will also be possible through the establishment of a systematic continuing education strategy of the national level. In this study, we tried to derive a strategy for continuing education for librarians in Korea by analyzing the internal and external environment of national institutions that are the center of continuing education for librarians. To this end, we proposed a complex framework of PEST-3Cs-SWOT as a systematic environmental analysis methodology and tried to apply it. For PEST analysis, literature related to library, librarian, and librarian education was extensively reviewed, and for 3Cs analysis, in-depth interviews with internal employees, questionnaire data analysis on the demand survey of training subjects, and case studies of similar institutions in Korea and abroad were conducted. Based on this, SWOT analysis was conducted, and finally, 4 strengths-opportunity strategic tasks, 5 weaknesses-opportunity strategic tasks, 5 strength-threat strategic tasks, and 3 weaknesses-threat strategic tasks were derived. This study will be meaningful in that it presents strategic tasks for continuing education institutions in Korea, and at the same time suggests and applies a complex analysis methodology that can be applied to tasks similar to development plans and strategy establishment.

This study was conducted to investigate the effect of integrated pest management (IPM) with 3point 5score microscopic monitoring method for laying farms infected with poultry red mites. A total of 8 laying farms infected with poultry red mites were divided into two treatments: 1) integrated pest management with 3point 5score microscopic monitoring method and 2) normal pest management with 3point 5score microscopic monitoring method. The results revealed that there is no significant difference between the groups with respect to the score of poultry red mites not only regardless of disinfection for the laying farms but also from week 4 to week 20 (P>0.05). However, the farm with IPM had a lower (P<0.05) score than those with the normal pest management method on week 24. Based on the result of the present study, controlling the presence of poultry red mites using IPM, along with consistent monitoring and supplementation using the 3point 5score microscopic monitoring method, is deemed effective in reducing the ultimately targeted infection rate of poultry red mites.

Though many insecticides are commercially available, development of resistance, pest resurgence and effects on non-target organisms led to the search for alternate insect pest management (IPM) strategy based on larval growth and reproductive fitness. Reproductive potential of insects depends on its acquiring of vitellogenic competence which is under hormonal control. Exogenous application of analogues of JR (JHAs) and ecdysterone could derail normal development and reproduction in insects by manipulating an array of physiological processes. In the rice pest, brown planthopper, Nilaparvata lugens, JHA, hydroprene induced metathetely from the fifth (final) instar nymphs in an age-dependent manner. Day 0 of the final instar showed highest sensitivity to induce this abnormal development. Adults emerged from treated day 3 nymphs looked normal. Both the morphotypes were reproductively incompetent and showed partial to complete sterility. Pre-adult exposure of the ovarian tissue to hydroprene suppressed mitotic division of germinal cells and induced abnormalities in the later s1ages of growth and differentiation of ovary in N. lugens. More over the nymphal exposure to hydroprene inhibited patency changes of follicular epithelium and affected competence of the follicles for yolk sequestration. In the absence of ovarian growth and oocyte differentiation, germarium found disintegrated, trophic core regressed and terminal oocytes resorbed. Hydroprene exposure to newly ecdysed brachypterous females did not affect ovarian development and egg production. Proper larval-adult transition appeared as a. prerequisite for vitellogenic competence in N. lugens for which the ovarian tissues must be exposed to ecdysterone in the internal milieu devoid of JH.

The use of bioactive materials derived from microorganisms and plants has played a role in pest management in environmentally-friendly agriculture (EFA) system. In Korea, a number of agricultural agents for the control of insect pests have been registered officially as biopesticides and marketed widely. However, most of the biopesticides has a limitation in the resource availability of bioactive materials, which has been one of main problems related to the commercialization of agricultural agents. Plant materials and microbial metabolites are the best sources as starting components to commercialize natural-occurring agricultural agents for pest management. The lack of modernized system for the standardization and quality control of the starting materials, however, has also received as a main problem related to the commercialization of agricultural agents. Considered that EFA business has kept growing bigger and bigger with global economic status, the commercialization of agricultural agents is necessary to meet the required number of agricultural agents officially available in EFA. This study describes the status and future prospects of pest control agents in EFA. A number of main issues hindered in the commercialization of agricultural agents are discussed in order to present a promising approach to successful commercialization.
