초록

감자(Solanum tubersum L.)의 주요 해충의 하나인 감자수염진딧물(Macrosiphum euphorbiae Thomas)에 의한 50개 감자 품종별 피해정도를 포장에서 검정하고 실내에서 배설 감로수와 식물체 내 성분(glycoalkaloids, total N, Ca, K, Mg) 함량을 품종별로 분석하여 피해도와의 상관성을 조사하였다. 50개 품종에 대한 감자수염진딧물의 포장 발생밀도 범위는 5엽당 $4.1{\sim}31.4$정도였으며, Jidose, Recent, Sebago 품종 등은 5마리 이하의 낮은 발생밀도를 보였다. 품종별 배설 감로수는 Jopoong에서 40.3개로 가장 많았고, 그 다음이 Superior로 37.7개였다. 가장 적은 품종은 Anco와 Shepody로 각각 15.7개, 16.7개였다. 포장실험과 실내시험 결과를 각 성분 함량별로 상관분석한 결과, 감자수염진딧물에 의한 피해는 glycoalkaloids 함량이나 전질소 함량과 정의 상관을 보였고, 나머지 식물체 성분함량과는 어떠한 상관도 보이지 않았다.

Fifty potato cultivars were screened for potato aphid, Macrosiphum euphorbiae Thomas infestation degree in the field. Aphid honey dew secretion and contents of foliar substances(glycoalkaloids, total nitrogen, Ca, K and Mg) of the cultivars were measured in the laboratory to analyze the correlation between infestation degrees and those factors. The number of aphids ranged from 4.1 to 31.4 per five leaves. The lower density(less than 5 aphids) was found on cvs. Jidose, Recent, and Sebago. The aphid secreted highest(40.3 droplets) and lowest(15.7 droplets) honeydew on cvs. Jopoong and Anco, respectively. Degree of infestation is positively correlated to glycoalkaloids and total nitrogen contents of the potato leaf.
