Abstract

Seven organophosphorus compounds and three carbamates of some monoterpenoids were synthesized and tested for insecticidal activity to five insects, brown plant happer (BPH, Nilaparvata lugens), green peach aphid (GPA, Myzus persicae), diamond bark moth (DBM, Plutella xylostella), tobacco cut worm (TCW, Spodoptera litura), and two spotted spider mite (TSSM, Tetranychus urticae). With the administration of 500 mg/l concentration thiophosphates of carveol and geraniol showed motality of from 95% to 100% to BPH and DBM. On the other hand, phosphates of menthol, thymol, and borneol had also good to moderate activity to BPH and TSSM insects at the same concentration.

7종의 monoterpene을 이용하여 phosphate, thiophosphate 및 carbamate를 합성하고, 이들 중 유기인계 화합물의 우리나라 주요 해충인 벼멸구(Nilaparvata lugens), 복숭아혹진딧물(Myzus persicae), 배추좀나방(Plutella xylostella), 담배거세미나방(Spodoptera liyura) 및 점박이응애(Tetraychus urticae)에 대한 살충효과를 조사하였다. 그 결과 500 mg/l 농도에서 carveol과 geraniol의 thiophosphate형은 벼멸구와 배추좀나방에 대하여 매우 좋은 살충효과를 보였는데 특히 carveol의 thiophosphate는 250 mg/l 농도에서도 벼멸구에 대한 살충력은 100%였다. 한편 menthol, thymol 및 borneol의 경우는 phosphate형이 thiophosphate형보다 벼멸구와 점박이응애에 대해 높은 효과가 있는 것으로 나타났다.
