Abstract

This study was performed to investigate the contact toxicity, fumigant toxicity, and synergistic effect using agricultural materials (AM) when mixed with selected essential oils against oak longicorn beetle, Moechotypa diphysis. Four kinds of AM, namely, chungkiller, ungsalta, jinap, purunjunsa showed 100% contact toxicity at one day after treatment. Subsequently, four AM was tested the fumigant toxicity during 24 hours. At concentration of 1 mL, jinap and chungkiller showed 100% mortality at 3 hr after treatment, prunjunsa and ungsalta showed 100% mortality at 6 hr after treatment. When applicate to the small vinyl bag (15 L), all AM (50 mL/15 L) was showed 100% mortality. Jinap showed the mortality 100% when mixed pennyroyal oil with the ratio of 5+1. It was higher than single treatment.

본 연구는 표고 원목을 재배시에 골목을 가해하는 털두꺼비하늘소(Moechotypa diphysis) 성충에 대하여 농자재 4종(chungkiller, jinap, purunjunsa, ungsalta)과 식물정유 3종(rosemary, sage, pennyroyal)에 대해서 접촉독성, 훈증독성 및 식물정유와 혼합시 상승효과를 검토하였다. 접촉독성은 농자재 4종 모두 100% 살충율을 보였으나, 3종의 식물정유는 모두 0% 살충율을 나타내었다. 이 4가지 농자재를 이용하여 $3{\sim}24$시간까지 훈증독성 발현속도는 1 mL/1 L air의 농도에서 jinap과 chungkille는 3시간 이내, ungsalta와 puruniunsa는 6시간 이내에 100% 살충효과를 보였다. 15 L(air)의 비닐용기에서는 10 mL의 처리농도에서 ungsalta(0%)를 제외한 3종 약제 모두 100%의 훈증효과를 나타내었다. 5 mL의 처리농도에서는 jinap과 prunjunsa 만이 50%와 62.6%를 나타내었으나 대조약제인 metam-sodium은 100%의 훈증효과를 나타내었다. Jinap과 Pennyroyal oil의 5:1(mL/15 L)혼합 처리에서 100%의 훈증효과를 나타내었으며, 단제 처리보다 높았다.
