裵泰雄,曺種澤,河祥永,韓熙世,文炳周 東亞大學校 1979 東亞論叢 Vol.16 No.2

거북밀깍지벌레의 效果的인 防除法을 규명하기 위하여 釜山地域에서의 發生消長을 검토하고, 4종류의 寄主別로 기계유유제, 有機燐劑 3종 및 Carbamate劑 3종을 공시하여 殺蟲率을 Bliss의 Probit법으로 분석하고 農藥의 농도에 따른 蟲體의 呼吸代謝를 검토 하였다. 1. 釜山地方에서의 거북밀깍지벌레의 孵化器는 6月15日∼7月12日이였으며 孵化最盛期는 7月 初旬이였다. 2. 防除適期는 8月10日경이었다. 3. 8月3日에 처리한 寄主別의 본 害蟲의 LD?이 가장 낮은 것은 자목련에서는 DEP, 감나무에서는 BUX,사철나무와 치자나무에서는 BUX와 DEP로서 전체적으로 볼 때 BUX 및 DEP가 가장 效果的이고 그 다음이 Diazinon이였다. 4. 8月18日 처리에서 LD?이 가장 낮은 것은 자목련과 감나무에서는 Diazinon이, 사철나무와 치자나무에서는 BUX와 DEP로서 전체적으로 보면 Diazinon, BUX와 DEP등이 感受性이 높았다. 5. 8月3日의 처리에서 LD?이 가장 낮은 농약은 BUX로서 寄主別 농도 범위는 0.011∼0.043%였다. 6. 8月18日의 처리에서 LD?이 가장 낮은 농약은 BUX와 Diazinon으로서 寄主別 농도 범위는 각각 0.011∼0.1076%, 0.028∼0.074%였다. 7. 本 害蟲의 正常 酸素消費量은 9.25∼10.02㎕O₂/㎎ body weight/hour였으며 寄主에 따른 차이를 인정할 수 없었다. 8. Diazinon과 BUX에서는 농도가 높아질수록 산소소비량은 정상호흡량 보다 훨씬 증가하였으나 기계유유제에서는 감소되었다. In order to investigate the effective control of Florida was scale (Cerostegia japonicus), the seasonal occurrences of 1st in star in Busan area was examined, the insecticides tested with the different four hosts were carbamates(NAC,BUX BPMC), organicphosphates(DEP,MEP,Diazinon)and Machine-oil emulson, and the mortality was analyzed by the probit analysis. Also the effects of insecticide's concentration on respiratory metabolism of Florida wax scale was examined. The results obtained were as follows 1. The periods of the larva occurrence was from June 15 to July 12, and the major peak of its occurrence was found to be in the early July. 2. The adequate period for the effective control of Florida wax scale was about August 10. 3. The lowest insecticides of LD 50 values to Florida wax scale with each hosts in August 10 was DEP in the people magnolia, BUX in the persimmon tree, BUX and DEP in the spindle tree and the gardenia. So generally the most effective insecticides for controlling it were BUX and DEP, Diazinon was the next. 4. In the second experiments treated in August 18, the lowest insecticide of LD50 values to it was Diazinon in the purple magnolia and the persimmon tree, BUX and DEP in the spindle tree and the gardenia. So the susceptibility of it to the insecticides was highest in Diazinon, BUX and DEP. 5. The lowest insecticide of LD90 values to it was BUX and the concentration range by the hosts was from. 0.011% to 0.043%. 6. In the second experiment treated in August 18, the lowest insecticides of LD90 values to it were BUX and Diazinon, and the concentration ranges by the hosts were from 0.011 to 0.1076%, 0.028 to 0.074% respectively. 7. The normal oxygen consumption of Florida wax scale was from 9.25 to 10.02㎕O₂/㎎ body weight/hour and wasn't recognized the significance by the hosts. 8. The oxygen consumption of it in Diazinon and BUX was higher with increasing of insecticides concentration than the normal respiratory, but it was decreased in machine oil emulsion.

딸기 검은 무늬病菌, Alernaria alternate (Fr.) Keissler의 몇가지 培養的 性質, 營養生理 및 葉劑防除 效果에 대하여 實驗한 結果를 要約하면 다음과 같다. 1. 供試菌의 菌叢빛깔은 菌株, 培地, 溫度, vitamin 및 炭素源에 따라 差가 있었다. 2. 公試菌의 K-3菌株는 一般的으로 溫度, 培地, 炭素源 및 vitamin에 관계없이 K-2와 J-1菌株에 비하여 菌絲生長 速度가 빠르고 分生胞子가 많이 形成되었다. 3. 公試菌의 菌絲生長은 菌株 모두 天然培地에서는 良好하여 PDA에서 가장 效果的이었고 다음은 V-8 Agar, CMA의 順이었고 合成培地에서는 K-3菌株는 生長하였으나 K-2, J-1菌株는 극히 不良하였다. 分生胞子 形成은 菌株 모두 V-8 Agar에서 가장 많이 形成되었으며 그 외 公試培地에서는 저조하였다. 4. 公試菌의 菌絲生長과 分生胞子形成 溫度범위는 10~35℃이며 最適溫度는 28℃ 부근이었다. 5. 公試菌의 J-1, K-2菌株는 菌絲生長에 thiamine 결핍 菌株이었으나 K-3菌株는 pyridoxine 첨가에 의하여 生長이 촉진되는 경향이었다. 分生胞子形成은 菌株 모두 pyridoxine 添加에 의하여 촉진 되었고 inositol, biotin도 效果的 이었으나 thiamine은 오히려 胞子形成을 억제하였다. 6. 菌絲生長은 thiamine 濃度間에 뚜렷한 차이가 없었고 分生胞子形成은 K-3菌株에서는 pyridoxine 120r/l, J-1, K-2菌株에서는 100r/l에서 最高形成量을 나타내었다. 7 公試菌의 J-1, K-2菌株는 供試한 7種의 炭素源 모두 thiamine 또는 thiamine과 pyridoxine이 存在하지 않는한 菌絲生長과 分生胞子形成에 效果가 없었다. thiamine 添加될 경우 菌株 모두 菌絲生長에 있어서는 多糖類인 dextrin과 starch에서 가장 效果的이었고 分生胞子形成에 있어서도 多糖類인 starch, dextrin, 複糖類인 maltose, sucrose가 가장 效果的이었다. 8. 公試葉劑中 菌株에 관계없이 zineb, zimaneb가 本 病의 防除에 가장 效果的이었고 다음은 crovral, polpan, daconil, captan順이었다. The experiments were carried out to investigate the cultural characteristics, nutritional physiology and chemical control of Alternaria alternata, the causal fungus of strawberry black leaf spot. The results obtained were summarized as follows. 1. The color of colony surface of the fungus varied with the isolates, culture media, temperatures, vitamins, and carbon sources. 2. Of the 3 isolates tested, in general, isolate K-3 grew better and produced more conidia than did the other two isolates. 3. Of the 5 media tested, P.D.A. gave the most radial growth, followed by V-8 Agar and C.M.A., Richard`s Agar and Czapek`s Agar were the least, whereas isolate K-3 grew well on 2 synthetic media. Most conidia formed on V-8 Agar. 4. Optimum temperature for the mycelial growth and conidial formation of the fungus was near 28℃. 5. Of the 3 isolates tested, isolate J-1 and K-2 were thiamine-deficient organism, but isolate K-3 didn`t require thiamine-hydrochloride. Pyridoxine hydrochloride was the most effective on conidial formation of all 3 isolates, followed by inositol and biotin. 6. No statistically significant differences were convinced among the concentration of thiamine-hydrochloride for the mycelial growth and the oprimum concentration of pyridoxine-hydrochloride for the conidial formation was about 120r/l in isolate K-3, and 100r/l in isolates K-2 and J-1. 7. Seven kinds of carbon sources tested were not utilized by isolate J-1 and K-2, so far as thiamine-hydrochloride was not added. When thiamine-Lydrochloride was added, dextrin and soluble starch were the most favorable for the mycelial growth. In the conidial formation, soluble starch, dextrin, maltose and sucrose were the most effective. 8. Under the condition of artificial infection, zineb and zimaneb were the most effective in controling the strawberry black leaf spot and followed by roval, polpan, daconil and captan.
