In the random screening of nematicidal compounds against the pine wood nematode, Bursaphelenchus xylophilus, using the immersion test, a series of N-alkyl- and N, N-dialkyl oleylamines, dialkylamines, and their related compounds were tested. Among these tested, didecylamine was identified as the most potentially-active nematicidal compound (LC50 ; 4.19μM, 1.24ppm). Amongst a total of 23 alkylamines, six N- and N, N-dialkyl oleylamines, including oleylamine, and three dialkylamines showed a higher activity than octadecylamine (LC50 ; 8.61μM, 2.08ppm) on a concentration basis. A total of 9 compounds tested indicated higher activity than octadecylamine on a molar basis.
在随机筛选对松木线虫(Bursaphelenchus xylophilus)具有灭虫作用的化合物时,通过浸泡测试检测了一系列N-烷基和N,N-二烷基油酸胺、二烷基胺及其相关化合物。经过测试,二十二烷胺被确定为最具潜力的灭虫化合物(LC50;4.19μM,1.24ppm)。在总共23种烷基胺中,包括油酸胺在内的六种N-和N,N-二烷基油酸胺,以及三种二烷基胺在浓度基础上表现出比十八烷胺(LC50;8.61μM,2.08ppm)更高的活性。总共有9种测试化合物在摩尔基础上显示出比十八烷胺更高的活性。
