杀幼虫的

The antiparasitic effect of caprylic acid against several fish parasites, i.e., the ciliate Cryptocaryon irritans, monogenean Benedenia seriolae, copepod Pseudocaligus fugu and myxosporean Kudoa shiomitsui, was examined by in vitro trials.Caprylic acid at a concentration of 1 mM had a parasiticidal effect against C. irritans theronts, B. seriolae oncomiracidia and K. shiomitsui spores and a contractile effect against B. seriolae adults, but had no clear effect against P. fugu copepodids and adults.

在体外实验中研究了辛酸对多种鱼类寄生虫的抗虫效果，如纤毛虫刺激隐核虫、单殖吸虫鰤贝尼登虫、桡足类Pseudocaligus fugu和微孢子虫库道虫。1mM的辛酸对刺激隐核虫滋养体、鰤贝尼登虫纤毛幼虫和库道虫孢子具有杀虫效果，对鰤贝尼登虫成虫有收缩效果，但对Pseudocaligus fugu的桡足幼体和成虫无明显效果。
