초록
사과원(園)의 관리상태(管理狀態)에 따른 사과굴나방 피해엽율(被害葉率), 기생봉류(寄生峰類)의 기생률(寄生率), 주요품종(主要品種)에 대한 피해엽율(被害葉率)의 차이(差異)와 세대(世代) 및 피해정도(被害程度)에 따른 피해엽(被害葉) 면적(面積)을 조사(調査)하여 다음과 같은 결과(結果)를 얻었다. 1. 사과굴나방의
Leaf damage rate and actual damaged leaf area by the apple leaf miner (ALM), Phyllonorycter ringoniella(Matsumura), and its parasitism were investigated in 1982 and 1983 in apple orchards. Percent leaf damage was higher in the occasionally sprayed orchards than in the periodically sprayed orchards from May to August, but the trend was reversed after September. Seasonal changes of the leaf damage seemed to be different with the varieties of apple trees. A few species of Eulophidae and Holcothorax testaceipes R. of Encyrtidae were the predominant parasites of the ALM. Overall percent parasitism was highest in the 5th (overwintering) generation, and conspicuously decreased in the 3rd-4th generation (July-August) when insecticides were sprayed periodically. Actual damaged leaf area per mine of the ALM was apparently different with the generations;
