自然度에 따른 冬柏나무寄生 뿔밀깍지벌레(Cerolpastes pseudoceriferus Green)의 發生에 관한 硏究 = The Rate of Appearance of Ceroplastes pseudoceriferus Green on Camellia according to the Degree of Nature

국문 초록 (Abstract)

最近 都市化에 의한 環境汚染의 增加로 뿔밀깍지벌레의 寄生이 增加되어 被害樹木이 多量 發生하는데, 木浦市를 대상으로 環境汚染의 程度에 따라 自然度를 分類하여 發生程度를 調査하였던 바 다음과 같은 結果를 얻었다. 뿔밀깍지벌레의 寄生은 多樣한 宿主植物 중 거의 동백나무에 限定되어 發生하였고, 계요 등과 장미에서 小數 幼蟲이 발견되었다. 自然度가 낮은 木浦市廳의 경우 發生指數 0.88로 가장 發生이 심하였고, 共用버스터미널은 0.80 그리고 新安비치호텔은 0.71로 發生이 심하였다. 自然度가 높은 儒達山, 下塘新都心 그리고 連山洞農工團地의 경우 發生指數 0으로 發生指數와 環境과의 密接한 관계를 나타내었다. 自然度別의 發生指數는 例外는 있었지만 平均的으로 環境汚染이 높은 地城은 0.78, 中地域은 0.40, 낮은 地城은 0.01로 發生指數와 環境과의 密接한 관계를 나타내었다. 뿔밀깍지벌레의 寄生은 植栽形態別로는 超密植된 樹木들에서, 規格別로는 小徑木에서, 樹勢別로는 衰弱한 樹木에서 發生指數가 높았으며 樹木內의 部位別로는 어린가지에서 심하였다. 뿔밀깍지벌레의 서식밀도를 낮추기 위하여 樹木의 活力增進, 天敵壓을 높이는 方案과 壞息環境의 改善이 필요하였다.

Recently, because of increasing urbanization and environmental pollution, the parasitism of Ceroplastes pseudoceriferus increased and various trees suffered heavily.
Reserching occurrances and the classfication of a natural degree in a degree of environmental pollution in Mok-po city, obtained following results;
1. The parasitism of Ceroplastes pseudoceriferus occurred limited Camellia of host plants and discovered a few larvae in Rosa and Paederia.
2. In case of the Mok-po city hall, representing a low natural degree an index of occurrance was 0.88, which was very serious, Bus terminal was 0.80 and Shin-an beach hotel was 0.71.
3. In case of M.t. Yu-Dal, Ha-Dang the new heart of the city and the agicultural and industrial complex in Yonsan-Dong, an index of occurrance was 0, couldn't recognize the parasitism. An index of occurrance has much to do with the environment.
4. An index of occurrance in a natural degree, was except, but on an average, the high area was 0.78, the middle area was 0.40 and the low area was 0.01, so an index of occurrance has much to do with the environment.
5. The parasitism of Ceroplastes pseudoceriferus was a high index of occurrance that a planting and existing form was very croud trees, that a standard was small caliber trees and that the strength of a tree was weak trees and in the part of a tree, a limb was very serious.
6. To control of insect pests, the improvement of vital power in trees, a plan increased a natural enemy and an endeavor for the improvement of environment, were demanded.
