Soil microarthropods and heavy metal concentrations in the watershed soil of Hantan River, and water quality of streams were investigated. Heavy metal concentrations of the watershed soil was higher in Shincheon stream where the water quality was lover than the other investigated streams. And soil pH was lowest in the watershed of Shincheon stream. Especially, the concentration of Cr in the watershed soil of Shincheon stream was 2 to 3 times higher than the other investigated sites. Most abundant soil invertebrates were Acari and Collembola, whose proportion was over 90% in the total density. The density of soil invertebrate was much lower in the watershed soil than in the riverbank soil. Among the watershed soil sites, the density of soil invertebrates was lowest in the Shincheon stream which had the lowest water quality and higher concentration of heavy metals in its watershed soil. Biomass of Diptera and Coleoptera were higher in the watershed soils than in the riverbank soils. In the watershed soil of Shincheon stream the biomass of Diptera was much more prominent.

裵允煥,玄在善 한국응용곤충학회 1987 한국응용곤충학회지 Vol.26 No.1

벼의 초기(初期) 발생해충군(發生害蟲群)의 방제(防除)를 위(爲)하여 쓰이고 있는 몇가지 침투성(浸透性) 살충제(殺蟲劑)의 초기(初期) 비래(飛來) 벼멸구에 대(對)한 방제효과(防除效果)를 평가(評價)하기 위하여 carbofuran(3G)과 disyston(3G)를 이앙직전(移秧直前)(5월(月) 27일(日)) 토중혼입(土中混入)과 수면시용(水面施用)하였고, omethoate 50% EC는 이앙(移秧) 6일후(日後)에 엽면산포(葉面散布)한 다음 6월(月) 11일(日), 21일(日), 7월(月) 2일(日), 11일(日), 25일(6月 11日, 21日, 7月 2日, 11日, 25에 pot당(當) 벼멸구를를 10쌍식(雙式) 접종(接種)하고 10일후(日後)부터 벼멸구의 밀도(密度)를 조사(調査)하였다. 최종밀도(最終密度)를 기준(基準)으로 생각할 때 산포후(散布後) 약(約) 10일경(日頃)까지는 모든 처리구(處理區)에서 엽효(葉效)가 인정(認定)되었으나 그 이후(以後)에는 carbofuran 처리구(處理區) 이외(以外)에서는 효과(效果)를 인정(認定)할 수 없었다. carbofuran처리구(處理區)에서는 수면시용(水面施用)에 비(比)하여 토중혼입구(土中混入區)에서 약효지속기간(藥效持續期間)이 약(約) 일간(日間) 지속(持續)되어 6월중순(月中旬)하순(下旬)까지 비래(飛來)하는 벼멸구에 대(對)한 밀도억제효과(密度抑制效果)를 기대(期待)할 수 있을 것으로 사료(思料)된다. The control effect of three systemic insecticides on the brown planthopper, carbofuran 3G, disyston 3G, and omethoate 50% EC, which have been used to control of the insect pests on rice crop in its early growing season, were evaluated. Soil incorporation and water broadcasting methods before transplanation were used for carbofuran and disyston, and omethoate was applied as foliar spray 6 days after transplanation. Ten pairs of newly emerged adults were inoculated on June 11, 21, July 2, 11, and 25. The number of the brown planthoppers on the rice plane were examined by means of direct reading. The three insecticides were effective for about ten days regardless of application methods, thereafter, fail to control of the insects except carbofuran. By means of soil incorporation, carbofuran could control the insects effectively for 45 days or longer, and it seemed to be able to control the progeny of the migrated brown planthopper until middle or late June.

환경도태압이 다른 두 활엽수림에서 낙엽분해에 관여하는 토양미소절지동물에 관한 연구

배윤환 대진대학교 1998 大眞論叢 Vol.6 No.-

The second year study with litter bags was carried out to investigate the soil invertebrate community in the process of leaf decomposition in Namsan and Kwangreung deciduous forests. Acari and Collembola were majou groups: Acari and Collembola were about 60% and 30% of total soil animals in their numbers, respectively. Among minor groups, Araneae, Chilopoda, Diplopoda, Diptera, Coleoptera and Formicidae were comparatively dominant. In Namsan forest which was considered to be under higher environmental selective pressure than Kwangreung, the densities of Collembola were somewhat higher than in Kwangreung. The densities of Chilopoda, Enchytraeidae and Nematoda were much higher in Namsan than in Kwangreung but Diplopoda, Symphyla and Hemiptera were much more in Kwangreung. It was expected that those groups could be used as bioindicators. The second year's densities of soil animals showed the peak in May but it was much lower than first year's densities. Acari showed no prominent peak density in its population trend in the second year study, which was a contrast to the result of first year's study.

본논초기 해충군과 비래성 멸구류의 밀도억제를 위한 살충제의 체계적 처리에 관한 연구

배윤환,이준호,현재선 한국응용곤충학회 1994 한국응용곤충학회지 Vol.33 No.4

우리나라의 본농초기 해충군과 비래성 멸구류를 통합관리할 수 있는 살충제의 체계적 처리법을 확립하기 위하여 이앙직접 carbofuran 토양혼화처리후에 벼멸구 비래시기와 buprofezin 처리시기 및 처리약량을 달리하였을때의 벼멸구 밀도 억제효과를 조사하였다. 이앙직전 carbofuran (3G) 토양혼화처리의 효과로부터 벗어난 7월중 비래 벼멸구에 대한 buprofezin (25% WP)의 적정처리시기는 7월말~8월초이었다. 이때 buprofezin 의처리약량은 관행처리량보다 훨씬 낮은 수준인 7.0 g a.i./10a으로도 벼멸구의 증식밀도를 효과적으로억제할 수 있었다. 이와 같은 carbofuran 토양혼화처리와 buprofezin 처리는 흰등멸구에 대해서도 탁월한 방제효과를 나타내었으며 멸구류를 천적인 거미밀도에 대해서는 영향을 미치지않았다. 따라서 우리나라의 수도해충 발생특성을 고려할 때 carbofuran 과 buprofezin을 이용한 살충제 체계적 처리 즉, 이앙직전 carbofuran 토양혼화처리후 7월말-8월초 bupro-fezin처리는 본 논초기 발생해충들 및 비래성 멸구류를 효과적으로 방제할 수 있는 방제체계로 생각된다. This study was conducted to establish a nce insect pest control system, ~ es.ys tematic application of insecticides using carbohran and buproiezin, in Korea. The effects oi various dates of application and rates of buprofezin (25% WP) after carbofuran (3G) soil incorpombon in late May on the pop~~lation densities of the brown planthoppa (BPH) immigrating in July were investigated Appropriate application tune of buprofezin for the BPH that had evaded insecticidal effect of 5011 incorporated carbofuran was late July-early August. Application rate of buprofezln at 7.0g a.i/lOa was enough to suppress the BPH density. Buprofezin treatment after carbofumn soil incorporation could also suppress the whlte backed planthopper population but did not affect the densities oi the paddy rice spiders. Considering the charactenstics of occurring patterns of the nce insect pests in Korea. buprofezin treatment m late July or early August after carbofuran soil incorporation in late May can be a useful application system of ir~sectic~deins controlling early season Insect pests and migmtoly planthoppers on rice.

Buprofezin 25% WP의 처리시기와 벼멸구(Nilaparvata lugens Stal) 밀도억제효과

배윤환,이준호,현재선 한국응용곤충학회 1992 한국응용곤충학회지 Vol.31 No.4

These studies were conducted to investigate the biological effects of buprofezin 25% WP on the adult of the brown planthopper (BPH) and its control effects on the BPH population, when buprofezin was treated on different days after the introduction of the BPH adult to the potted rice. Also age structures of the BPH population at the time of buprofezin treatment were observed. The results were as follows: Buprofezin (7.0 g a.i./l0 a) could reduce the longevity and fecundity of the newly emerged female but did not affect the biology of older female, and it did not affect the biology of the male. The larval densities at the time of buprofezin treatment was reduced to nearly zero after treatment. The higher the residual effect and the proportion of larvae at the time of buprofezin treatment were, the higher its con¬trol effect on the BPH population was. In case of buprofezin 7.0 g a.i./l0a treatment, the time interval of treatment that could show the highest control effect was about 10 days (from 18 days after the adult introduction to the adult emergence days of next generation). 폿트에서 벼멸구 성충을 접종하고 buprofezin 처리시기를 달리하였을 때, 접종성충에 미치는 영향 및 약처리시기에 따른 벼멸구 밀도억제효과를 약처리당시의 연령구성과 관련하여 조사하였다. Buprofezin (7.0 g a.i./10 a)은 벼멸구 수컷에 대해서 영향을 미치지 않았으며 갓 우화한 벼멸구암컷에 대해서 수명과 산란수의 감소효과가 있었으나 우화후 3일 이상 경과한 성충의 수명이나 산란수에는 영향을 미치지 않았으며 buprofezin 처리당시의 유충군 밀도는 약처리후 급격히 저하되었다. Buprofezin의 벼멸구개체군 밀도억제효과는 처리약량이 높을수록, buprofezin 처리당시 buprofezin의 약효지속효과내에 노출된 유충군의 비율이 높을수록 좋았는데 buprofezin 7.0 g a.i./10 a 처리의 경우 적정처리시기는 접종 18일후부터 접종후 제1세대 성충이 출현하기 직전까지 약 10일간이었다.

Toxicity of polymer, Alum, Zeolite, Loess, Koalinite and Chitosan on earthworm and the effects of sewage sludges coagulated by several mixtures of those coagulants on the population growth of earthworm Eisenia andrei were evaluated. Under the concentration of 20,000 mg/L of Zeolite, Loess and Kaolinite, and under 1,000 mg/L of Chitosan were there no acute toxicities on earthworms. The concentration of Polymer over 160 mg/L showed acute toxicity upon earthworm, but the concentration under 80 mg/L showed no toxicity. The concentration of Alum over 125 mg/L showed acute toxicity. The mixture of ‘Polymer 80 mg/L + Kaolinite 500 mg/L + Chitosan 20 mg/L’ had higher coagulating efficiency than the ‘Polymer 80 mg/ L + Kaolinite 500 mg/L’ on sewage sludge, And the sewage sludge coagulated by former mixture induced higher growth rate of earthworm population than that coagulated by latter mixture when the sewage sludges were supplied to earthworms.

벼멸구(Nilaparvata lugens Stal) 유충에 대한 Buprofezin의 약효지속효과 및 몇가지 생물학적 영향

배윤환,이준호,현재선 한국응용곤충학회 1992 한국응용곤충학회지 Vol.31 No.4

Buprofezin(25% WP)의 처리약량에 따른 벼멸구 유충에 대한 약효지속기간 및 buprofezin이 벼멸구 유충에 미치는 생물학적 영향을 폿트실험으로 조사하여 다음과 같은 결과를 얻었다. Buprofezin의 벼멸구 2령유충에 대한 약효지속효과는 상당히 길며, 처리농도가 높을수록 약효지속기간도 길었다. 17.5 g a.i./10 a 처리는 약처리 35일후에도 90%정도의 살충효과를 유지하였고, 5.78~11.50 g a.i./10 a 처리는 $RLT_{90}$(90% 이상 상충률을 유지하는 약처리후 경과시간)이 9.0~13.5일, $RLT_{50}$(50% 이상 살충률을 유지하는 약처리후 경과시간)은 16.8~22.8일로 추정되었다. 그리고 벼멸구 2령유충에 대하여 약처리 15일까지 95%이상의 살충력을 유지할 수 있는 buprofezin 처리약량은 13.00 g a.i./10 a이었고, 50%이상의 살충력을 유지할 수 있는 처리약량은 4.44 g a.i./10 a로 추정되었다. Buprofezin 7.0 g a.i./10 a 처리는 벼멸구 1령유충에 대하여 약처리 17일후까지 100%의 살충률을 유지하였으며 1령유충에 대한 $RLT_{50}$은 32.5일로 같은 농도의 2령 약충에 대한 $RLT_{50}$보다 15일정도 길었다. Buprofezin(7.0 g a.i./10 a)은 처리당시 4령까지의 유충을 100% 치사시켰고, 5령유충에 대해서는 우화전까지 약 70%의 살충력을 보였으나 5령이 생존하여 우화한 성충암컷은 수명이 현저하게 감소하였고 전혀 산란을 하지 못하였다. Residual and biological effects of buprofezin(25% WP) on the larvae of the brown planthopper(BPH), Ni/aparvata /ugens SUlI, were studied by pot experiments. Residual lethal effects on the 2nd instar larvae lasted significantly long, and were higher with application rates. The rate of 17.50 g a.i./10a showed ca. 90% mortality even on 35 days after treatment (OAT). $RLT_{90}$ and $RLT_{50}$(residual lethal time that can show 90% and 50% mortality, respectively) with rates of 5.78-11.50 g a.i./lOa were 9.0-13.5, and 16.8-22.8 days, respectively. It was estimated that 13.00 and 4.44 g a.i./lOa were the rates of buprofezin which could show mortalities of 2nd instar BPH larvae above 95% and 50% until 15 OAT, respectively. The residual lethal effect of 7.00 g a.i./10a on the 1st instar BPH larvae was 100 % even on 17 OAT. $RLT_{50}$ was 32.5 days which was 15 days longer than $RLT_{50}$ for the 2nd instar larvae. Buprofezin with 7.0 g a.i./lOa showed 100% and 70% mortality for 1st-4th and 5th instar BPH larvae, respectively. Longevity of a female BPH which emerged from the 5th instar larvae treated by buprofezin was greatly reduced, and its fecundity was nearly zero.

돈분 퇴비의 부숙기간이 줄지렁이의 섭식률, 생체량 및 산란율에 미치는 영향

배윤환,박광일 유기성자원학회 2013 유기물자원화 Vol.21 No.2

Effects of pig manure with various composting periods(0, 15, 30, 50, 80 days) on feeding rate, biomass, cocoon production of earthworm(Eisenia fetida) population and physicochemical property of vermicast produced from pig manure were investigated. The feeding rate of earthworm was increased with longer composting period of pig manure. But the biomass production of earthworm population was highest upon the pig manure composted for 30 days. Upon the pig manure composted for 80 days, the biomass was severely reduced. Cocoon production was decreased with longer composting period and especially lower on the pig manure composted for 80 days. Values of pH, EC, C/N ratio of vermicasts produced from pig manure composts were lower than those of pig manures. And the organic material contents of vermicasts were uniformly reduced irrespective of composting duration of pig manure, whose values were 35.9~39.8%. From these results, the optimum composting period of pig manure for vermicomposting could be 15~30 days. And the application of vermicomposting upon the composted pig manure could be an efficient way for the treatment of pig feces, which can stabilize and recycle the organic wastes more rapidly than the conventional composting method. 부숙기간(부숙 0일, 15일, 30일, 50일, 80일)이 다른 돈분퇴비에 대한 줄지렁이의 섭식량, 생체량, 산란율 및 돈분퇴비로부터 생산된 분변토의 이화학적 성상을 조사하였다. 돈분퇴비에 대한 지렁이 섭식량은 부숙 기간이 길어질수록 증가하였으나, 지렁이 생체량은 30일간 부숙된 돈분퇴비에서 가장 높았으며, 80일간 부숙된 돈분퇴비에서는 생체량이 현저하게 감소하였다. 지렁이의 산란수는 부숙이 진행된 먹이일수록 낮아지는 경향을 보였으며, 특히 80일간 부숙된 돈분퇴비에서 현저하게 낮았다. 부숙기간이 다른 돈분 퇴비로부터 생산된 분변토의 pH, 전기전도도, C/N율이 일반적인 퇴비화 공정보다 빠르게 감소되었으며, 생산된 분변토의 유기물 함량은 돈분퇴비의 부숙기간에 무관하게 35.9~39.8%으로 균질화되었다. 이상에서 지렁이의 처리효율, 생장률 등을 고려하였을 때, 돈분에 대한 지렁이처리를 위한 돈분퇴비의 부숙기간은 15∼30일 정도가 적정한 것으로 판단된다. 그리고 일반적인 퇴비화와 지렁이 처리법의 혼합적용에 의해 돈분을 효과적으로 처리할 수 있을 뿐만 아니라 양질의 분변토와 지렁이를 생산할 수 있을 것으로 생각된다.
