Abstract

Effect of monoterpene composition in pine needles on the susceptibility to pine gall midge (Thecodiplosis japonensis Uchida et Inouye) has been pursued. The pines studied include 5 susceptible and 2 resistant species. Also included were severely damaged or unaffected P. densiflora in the pine gall midge affected region. From the needles of the pine trees, 9 monoterpenes were identified by GLC. No correlationship, was found to hold in the monoterpene composition between pine gall midge susceptible and nonsusceptible pine species. Concentrations of limonene, however, gradually increased following oviposition in the unaffected P. densiflora while the concentrations of the monoterpene remained constant in the damaged P. densiflora. Effect of high limonene concentration in the needles of P. densiflora is discussed as a possible factor inducing resistance toward the pest in the unaffected Pinus densiflora.

소나무의 monoterpene조성(組成)가 솔잎혹파리에 대(對)한 저항성(抵抗性) 관계(關係)를 구명(究明)하기 위(爲)하여 솔잎혹파리 저항성(抵抗性) 소나무 5개(5個) 수종(樹種)가 감수성(感受性)소나무 2개(2個) 수종(樹種), 그리고 감수성(感受性) 해송(海松)가운데 피해목(被害木)과 선발목(選拔木)의 침엽(針葉)을 GLC로 분석(分析)하여 monoterpenes의 조성(組成)을 근거(根據)로 저항성(抵抗性) 또는 감수성(感受性) 수종(樹種)을 구별(區別)할 수는 없었다. 그러나 적송수종내(赤松樹種內)의 피해목(被害木)과 선발목간(選拔木間)에는 limonene, ${\alpha}-pinene$, myrcene 및 ${\beta}-phellandrene$의 농도(濃度)아 조성비(組成比)에 차이(差異)가 인정(認定)되였다. 적송(赤松)의 선발목(選拔木)에서 limonene의 농도(濃度)는 솔잎혹파리 산란이후(産卵以後) 점차(漸次) 증가(增加)하였으나 피해목(被害木)에서는 증가(增加)하지 않았다. 적송(赤松)의 선발목(選拔木)에서 솔잎혹파리에 대(對)한 내충성분은limonene으로 보였다.
