배추좀나방(Plutella xylostella L.)의 Fenvalerate에 대한 저항성 유전양식을 살충제 감수성과 해독댓활성 시험으로 조사하였다. 실내감수성계통(S)과 Fenvalerate도태저항성계통(R)의 정역교배에서 얻어진 양 (TEXS♀/TEX은 약량과 사망률 관계에서 감수성 차이가 없었다. 양 (TEXS♀/TEX의 우성도는 살충제 감수성에서 각각 -0.50, -0.46, 해독대사활성시험에서 각각 -0.85, -0.81로 나타났다. 따라서 fenvalerate저항성 유전자는 상염색체상에 존재하며 불완전열성에 의해 지배되는 것으로 나타났다.
This study was divised to observe an inhibitory toward a lipolytic action of toxohormone-L from large root and small root Nepal pseudo ginseng (NPG : Nepal products) components by water extract and ethanol precipitate in vitro. Toxohormone-L is known to be a lipolytic factor that was partially purified from the ascites fluid of sarcoma 180-bearing mice and of patients with hepatoma. The inhibitory effect that inhibited the lipolytic action of toxohormone-L by ethanol precipitate component of large root NPG(mean 46.8%) was higher (mean 1.8 times) than that of water extract component in final reaction concentration ; 500㎍/㎖, on the other side inhibitory effect of water extract component in small root NPG (mean 43.9%) was higher(mean 1.2 times) than that of ethanol precipitate component, respectively. In a way inhibitory effect of ethanol precipitate component in large root NPG(47.6%), when final reaction concentration of sample were l, 000㎍/㎖, was about 40% lower than that of Korean red ginseng, respectively.
