전국 9개 고정조사지에서 1968년이래 13개년간 조사한 솔나방의 10월의 밀도를 종합검토한바 다음과 같은 결과를 얻었다. 1. 13개년간에 솔나방의 10월밀도가 특히 높았던 년도는 '70년과 75년의 2회였으며 '76년이후는 단속 저밀도를 유지하고 있다. 2. 밀도가..
본 보고에서 서해안 개소의 매개 진딧물 밀도가 대관령에서의 밀도보다 대체로 낮았으나 장소에 따라서는 상당히 높은 사실을 밝힌바 있다. 새 감자의 평지생산방식이 현행방식보다 합리적이어서 유리하므로 그 생산휴계의 확립을 위한 기초자료를 얻고자 본 조사에 착수하였다. 서해안..
