  • Studies were conducted to find out the justification for levee-burning, customarily executed by farmers for long time, Experiments were carried out in farmers fields with levee-burning early in the season, and some pesticides spraying when necessary from 1995 to 1997. Some data collected are analysed and discussed from several available aspects of surroundings. In relation to some results obtained together with some previous evidences, levee-burning seems to have several adverse effects on levee destruction, partial cause of forest fire, and lowering of spider density in the field during fall, without providing any benefit, while causing no signifant effect on weed flora on levee, insect density in the field, and incidence of the rice-blast. Therefore, concequently, it could be recommend that the levee-burning by farmers should not be continued.

  • The pine mushroom fruit body have a harvest only from natural pine forest instead of artificial culture like other edible mushrooms until now on. We investigated the interrelationship between pine mushroom colonies and insect/invertebrates fauna, and changes of their seasonal populations. Two famous pine mushroom producing district were selected on Bong-wha and Gan-sung Eup, and were surveyed on the ground and in the soil with/without pine mushroom hyphae per month from June to November, 2005. There was some difference in collected Insects and invertebrates between two producing districts. Total number of collected species and individuals were 73 and 22, and 63 individuals with 19 species in Bon-wha and Gan-sung area, respectively. Otherwise, there were many mites and nematodes were living in soil with mushroom hyphae. The population densities of mites were Increased to November from June, however, the population of nematodes were fluctuated with low in hot weather and high in cool.

  • The study of insect fauna in Taeanhaean National Park in Korea began with the first survey of natural resources in 1996, and then the surveys were conducted seasonally from 2005 to 2014. The surveyed sites were mostly coastal areas, sand dunes, and back grasslands. Insects were collected by sweeping with insect net, suction, pitfall trap, light trap, and Malaise trap. As a result, a total of 1,540 species of 215 families belonging to 17 orders were identified. Lepidoptera was the most populous group at 34.2% and followed by Coleoptera at 28.3%, Hemiptera at 12.7%, Diptera at 8.5%, Hymenoptera at 7.1%, Orthoptera at 4.7%, Odonata at 2.0%, and others. The analysis of change of arenaceous insect fauna before and after the accident by the Hebei Spirit that spilt oil in Taean in December 2007 showed that 45 arenaceous insect species, mostly belonging to Coleoptera, were observed through the whole survey period. The impact of oil spill on the number of arenaceous insect species appearing in the area was minor.

  • 지구상에 살고 있는 곤충은 약 120여만 종으로 전체 동물의 70% 이상을 차지하는 것으로 보고되어 있으나, 누에와 꿀벌을 제외한 대부분의 곤충이 해충으로 취급되어, 자원화 곤충의 병ㆍ해충에 관한 정보는 미흡한 실정이다. 본 연구의 목적은 곤충의 대량안정생산을 위한 기초자료 확보차원에서 주요 자원화 곤충의 병ㆍ해충 발생현황을 파악하는데 있다. (중략)
