The agricultural development of Korea has occurred at the expense of natural resources and environmental quality, and, today, one of the most urgent problem in the practices of intensive livestock farming is disposing of the animal wastewater. As a result, soil and water degradation and other environmental deterioration become apparent and they cause long-term loss in agricultural production. This paper attempted to summarize the environmental problems associated with agricultural activities, and to get some implications to minimize agricultural environment problems. It is proposed that sustainable agricultural is one of desirable directions for future Korean agriculture. The goal of the sustainable agricultural effort is to utilize the potential environmental quality problem. Agricultural operations may be more dependent upon the production practices and waste management techniques utilized by farmers than the size of the operation, the number of animal fed, or amount of waste involved. Also low-input farming technology can be suggested one of them, and disposing system of agricultural residues and animal waste should be developed with intensive concerns and financial supports.

To obtain basic information on the detection of cellulolytic activity in Auricularia auricula-judae, the influences of dye reagent, pH, and temperature were assessed. Chromogenic dye (congo red, phenol red, remazol brilliant blue, and trypan blue) was individually incorporated into a medium containing either carboxymethyl-cellulose, Avicel, or D-cellobiose as a polysaccharide carbon substrate. The other assessments utilized pHs ranging from 4.5 to 8.0 and temperatures from $15\sim35^{\circ}C$. Overall, when A. auricula-judae species were transferred onto media contained Congo red and adjusted pH 7.0 and then incubated at $25^{\circ}C$ for 5 days, the clear zone indicative of cellulolytic activity was more pronounced.

We found the large narcissus fly, Merodon equestris (Fabricius), which has been doubted to occur in Korea. This species is an economically important in management of narcissus and also of quarantine pests. We therefore provide the morphological diagnosis and DNA barcode sequences for rapid species identification of M. equestris based on the five Korean specimens.
