전분 추출용으로 대부분 사용되고 있는 도토리 종실의 가해해충 사멸방법을 연구할 목적으로 현행 검역해충 사멸방법인 methyl bromide (MBr) 훈증처리와 감마선 조사법에 대하여 살충효과와 이들이 몇 가지 이화학적 품질에 미치는 영향을 비교 검토하였다. 국내산 도토리의 가해해충은 도토리밤바구미 (Curculio drntipes Roelofs)와 복숭아명나방 (Dichocrocis punctiferalis Guenee)으로 확인되었다. 이들
Comparative effects of gamma irradiation and methyl bromide (MBr) fumigation on disinfestation and some physicochemical attributes of acorn seeds were investigated. Insects in domestic acorns were identified to be Curculio dentipes Roelofs and Dichocrocis punctiferalis Guenee, which were easily disinfestated immediately after commercial MBr fumigation. Irradiation also showed similar effects on mortality of the insects in different post-irradiation periods; at 3rd day with doses of 1-3 kGy and at around 30th day 0.5-1 kGy. MBr fumigation caused the decrease in lightness (Hunter L value), total phenolics and reducing sugars and the increase in yellowness (Hunter b value) and browning intensity for the subjected samples, as compared with the nontreated control and irradiated ones at 0.5-2 kGy. Furthermore, MBr fumigation resulted in decay for the most part of samples during storage at 5-10 for 6 months in a PVC box packaging with nets. As a result, optimum levels of irradiation is expected to be roe of the alternatives to chemical fumigants.
