전북지방의 고랭지인 무주에서 진딧물의 밀도조사를 실시한 바 다음의 결과를 얻었다. 1. 진딧물의 종류는 감자바이러스 매개진딧물 4종을 포함하여 37종이었다. 2. 진딧물의 밀도는 평야부보다 훨씬 낮다. 3. 감자바이러스 매개진딧물은 복숭아혹진딧물(Myzus persicae), 싸리수염진딧물(Aulacorthum solami), 무테두리진딧물(Lipahis erysimi), 목화진딧물(Aphis gossypii)이다. 4. 본 조사지역의 우세종은 아카시아진딧물(Aphis craccivora), 누리장진딧물(Aphis clerodendri), 무테두리진딧물(Lipaphis erysimi)이다. 5. 진딧물의 발생소장은 평야부보다 늦게 출현하고 2순쯤 빠르게 동기주로 이동한다.

This survey was carried out in order to find out population density of aphid at the alpine area. Thetraps were set from May 1 to October 31 in 1973. The summarized results are as follows; 1. About 37 species of aphids were trapped, including 4 species of potatao virus vectors. 2. Of these, dominant species are Aphis gossypii Koch, Aphis lerodendri Matsumura, and Lipahis erysimi Kaltenbaeh. The $67\%$ of 3, dominant species consisted of the trapped total aphids. 3. The potato virus vectors are Myzus persicae Sulzer, Aulacorhum solani Kaltenbach, Lipaphis erysimi Kaltenbaeh and Aphis gossypii Glover. 4. Tile number of aphids and vectors at the alpine area is considerably lower than that at the level land. 5. The peak of the flying aphid occurrence is shown in the latter part of September.
