감수성품종과 저항성품종 밤나무를 가해하는 밤나무혹벌의 생태학적 특성을 비교하기 위하여 형태학적 조사와 변태에 따른 아미노산, 단백성질소, 비단백성질소, 탄수화물, 지질, 무기염류, 호흡능의 활성도에 대한 생리학적 조사를 한 결과는 다음과 같다. 1) 형태학적 조사를 위하여 란ㆍ산란관 촉각, 시맥, 각의 형태및 크기를 관찰하였으나 두 품종간에 유의한 차이를 찾을 수 없었다. 2) 아미노산은 감수성품종의 밤나무혹벌에서 16종, 저항성품종, 밤나무혹벌에서 13종이 검출되었고 alanine, aspartic acid, serine, valine은 모두 높은 농도를 나타냈다 3) 단백성질소ㆍ비단백성질소와 trehalose 모두 저항성품종의 밤나무혹벌이 높은 함량을 나타냈다. 4) 지질은 총지질, 인지질, monoacylglycerol, 유리지방산, triacylglycerol, ester cholesterol 이 분리되었으며 변태에 따른 생리적 U자형 곡선을 나타냈다. 지질의 함량은 저항성품종의 밤나무혹벌이 감수성품종의 그것보다 높았다. 5) 호흡능의 활성도는 감수성품종과 저항성품종의 밤나무혹벌에서 일정한 경향성을 보이지 않았다. 6) 무기염류의 함량변화는 변태기별로는 유충기와 전용기에 높았고, 저항성품종의 밤나무혹벌이 다소 높은 함량을 나타냈다.
In order to clarify the comparision of biological characteristics between susceptible and resistant hosts of the chestnut gall wasp, Dryocomus kuriphilus Yasumatsu, morphological and physiological investigation that is the concentration of free amino acid, protein nitrogen, non protein nitrogen, trehalose, lipids, mineral salts and respiratory activity were measured, respectively. The results are summarized as follows; Morphological investigation of the egg, the ovipositor, the antennae, the wing and the leg were measured, but can not found significant differences between the two varieties of the chestnut gall wasp. In susceptible varieties, amino acids were detected in a total of 16 but amino acids of resistant varieties were detected in a total of 13 The amino acids identified at each varieties are alanine, aspartic acid, cysteine, glutamic acid, glycine, histidine, leucine, methionine, serine, threonine and valine. In general, protein nitrogen, non protein nitrogen and trehalose content of resistant were more than susceptible. Also, total lipid' phospholipid, monoacylglycerol, free fatty acid, triacylglycerol and ester cholesterol were identified at each stage in both varieties, and changes of concetration through the course of the physiological cycle form a U-shaped curve during metamorphosis. The respiratory activities had no significant differences between susceptible and resistant varieties. The mineral salts presented were sodium, calcium, potassium and phosphorus, which were identified at each stage in both varieties. The mineral salts concentration of susceptible was by far lower than that resistant of the chestnut gall wasp. In conclusion, of the two ecospecies of the chestnut gall wasp which damaged susceptible and resistant varieties, morphological differences were insignificant, however, physiological differences brought out the metabolic pattern that resistant was more than susceptible.
