Abstract

The relative toxicity of some of the insecticides which have been used for the control of paddy rice insect pests in Korea was evaluated in the laboratory with the brown planthopper (BPH) Nilaparvata lugens, and a predaceous paddy spider Pirata subpiraticus. In order of the relative toxicity (LD5O value to spider/LD50 value to BPH) were PAP (0.4), MPP(0.1), MEP(1.8), diazinon(2.8), carbofuran(7.5), NAC(11.3), BPMC(17.5), Pyridaphenthion(35.9) and MIPC(65.7). MIPC and Pyridaphenthion were considered as having the desirable selective toxicity for the spider and the BPH.

현재 우리나라에서 사용되고 있는 수종의 수도용 살충제들에 대하여 벼멸구와 이의 주요천적인 황산적거미에 대한 상대독성을 실내에서 미량국소 처리방법으로 반치사약량을 조사 비교한 결과 PAP(0.4), MPP (0.7), MEP(1.8), Diazinon(2.8) , Carbofuran(7.5), NAC(11.3), BPMC(17.5), Pyridaphenthion(35.9), MIPC(65.7)의 순이었으며 특히 MIPC, Pyridaphenthion은 벼멸구와 황산적거미에 대해 선택성을 나타내었다.
