  • In this study, 5 species (Tetranychus kanzawai Kishida, Endoclyta excrescens (Butler), leaf roller caterpillar (Adoxophyes orana Fisher), Anomis mesogona (Walker), and Aulacaspis rosae (Bouche)) were found in Rubus coreanus Miquel in Jeonbuk province, from 2006 to 2008. T. kanzawai appeared in mid-May and showed three peaks in late June, mid-July, and late August. Its density was over 10 adults per leaf. A. mesogona appeared in mid-June and showed two peaks in late July, and early October. Of the 28 insect pests in pre-harvesting, the 7 main species were T. kanzawai, T. urticae, A. orana, Lygocoris lucorum Meyer, Frankliniella intonsa (Trybom), Psylliodes punctifrons Baly and Motschulskyia serrata (Matsumura). Of the 19 insect pests in after-harvesting, the 6 main species were T. kanzawai, E. excrescens, A. mesogona, A. orana, P. punctifrons and A. rosae. Growth of R. coreanus decreased when insect pests were not managed and yields decreased approx. 7% a year. Management of insect pests in field using pesticide was not different.

  • Road-map for the environmental friendly integrated pest management(IPM) of insect pests was drawn up on the strawberry vinyl-houses of farmer's field. Major insect pests were occurred Tetranychus urticae and Aphis gossypii during the strawberry plant seeding in the vinyl house and open field. Also, same insect pests were occurred in the vinyl house during harvesting season of strawberry. For the control of T. urticae and A. gossypii, Phytoseiulus persimilis and Aphidius colemani as natural enemies were input to the vinyl house, respectively. However, because these natural enemies could not control insect pest populations, acaricide and insecticide were sprayed. Then natural enemies were input again in the vinyl house. Natural enemies could not endure the intense cold and differences of temperature and relative humidity between day and night during strawberry harvesting season. So, their behavior and control activity of pests were more decrease than pests. Firstly, natural enemies are input in the vinyl house during the early breeding season of strawberry, secondly, acaricides and insecticide are sprayed for the control of mites and aphids, respectively, during the middle breeding season in the hard winter. Finally, natural enemies are re-input in the vinyl house during the middle and late breeding season.

  • 가을 김장용 무우, 배추는 우리나라 어디에서나 재배되고 재배면적도 크다. 그런데 해에 따라 풍년이 들기도 하고 흉년이 되기도 하는데 그 원인이 주로 병해의 발생 때문이다. 배추에는 무름병(軟腐病), 바이러스병(萎縮病), 무사마귀병(根瘤病), 버짐병(露菌病), 흰무늬병(白斑病), 밑둥썩음병(根腐病) 등이 피해를 많이 주고 방제에 신경을 써야하는 병이다. 무에는 바이러스병, 무름병, 버짐병, 검은빛썩음병(黑腐病) 등이 많이 발생한다. 흉년을 만들지는 않지만 상품가치를 떨어트리고 경우에 따라 상당히 많은 결주를 내어 소득을 저하시키는 것이 해충인데 무우, 배추 공히 거세미, 배추흰나비(청벌레), 벼룩잎벌레(톡톡이) 등이 피해를 준다.

  • 금년의 과수농사는 개화기에 다소 많은 비가 내렸고 강풍이 불어 다소 어려울 듯 하였으나 그후 생육기에는 안정되어 예년에 비하여 10$\%$정도 증수될 것으로 추정되고 있다. 이와같은 결과는 기상의 안정에 힘입은 바 크지만 농민들의 피와 땀의 결정이고 병충해 방제 및 모든 어려운 일을 슬기롭게 이겨낸 덕분이라 믿는다. 특히 금년 여름은 무던히도 더웠던 탓으로 후기에 굴나방, 점박이응애, 진딧물등 해충의 발생이 지역에 따라 심하였으며 과실의 숙기가 빨라진 탓으로 탄저병과 부패병(겹무늬병)이 약 20일 정도 일찍 발생되어 약제 방제를 소홀히 한 지역에서는 크게 문제가 되었다. 따라서 금년도의 기상과 병충해 발생 정도를 분석 진단하여 내년도 농사에 보탬이 되었으면 하고 과수별 주요 병해충을 진단해 보고자 한다.

  • Insect pests have been one of the main constraints affecting turf sod cultivation areas, playgrounds, parks, golf courses, airports and other related recreational grounds. However, turfgrass research has been very limited and confined within a limited period of time compared to other branches of crop science in Korea. This review was surveyed from all papers in KCI (Korea Citation Index), SCI (Scientific Citation Index) and SCIE (SCI Expended) journals related to turfgrass research in Korea. Fifty two papers concerning turfgrass insect pest in Korea have hitherto been published in 8 different scientific journals since 1990. Thirty three papers (63.5% of total) were published in Weed and Turfgrass Science. The main topics of focus were divided into two parts; ecological study and control of insect pests. Before the 1990 decade, there were no scientific papers published in relation to turfgrass insect pest science. However, during the 1990, 2000 and 2010 decades, 9, 10 and 14 papers were published respectively in Weed and Turfgrass Science. From 1997, about 2 papers were published per year in the scientific journals. Thirty three insect pest species belonging to 13 families in 6 orders, one Eriophyidae mite, Aceria zoysia and one Armadillidae sowbug, Armadillidium vulgare, have hitherto been listed as turfgrass arthropod pests in Korea. Fifty percent of turfgrass insect pest papers published were focused on whitegrub, Adoretus tenuimaculatus, Popillia quadrigutta and earthworm research in Korea.

  • 농업에 있어 해충 방제는 중요한 일이다. 특히, 볼록총채벌레는 최근 감귤원 해충 피해의 주요 해충으로 인식되어 주기적인 예찰이 이루어지고 있으나 성충의 크기가 0.8mm 정도로 작아 육안 식별에 어려움이 있다. 본 논문에서는 예찰 트랩에 포집된 볼록총채벌레를 자동으로 판별하기 위한 전처리 알고리즘을 제안하였다. 광학 현미경의 배율을 30, 40, 50배로 조정하여 영상을 획득하였고, 제안한 알고리즘을 적용하여 판별 성능을 측정한 결과, 50배율에서 가장 높은 판별율을 보였으나 더 많은 볼록총채벌레 영상을 대상으로 알고리즘을 테스트하고 개선할 필요가 있다.
