谭庆庆，吴惠妍，江世新，Ma H.B.（2013年）：不同剂量硫酸铜下松材线虫的死亡率和运动行为。植物保护。科学，49：98-103。在离体条件下，研究了不同浓度硫酸铜处理不同时间对松材线虫死亡率和运动行为的影响。硫酸铜对线虫B有较强的抑制作用。低浓度（5 mg/l）时，8、24、48和72 h的半数致死浓度（LC 50）分别为31.634、7.353、6.557和5.568 mg/l。B的死亡率。经不同浓度硫酸铜处理6、8、24、48和72 h后，与蒸馏水对照组相比，差异极显著（P < 0.01）。线虫的运动活性随着暴露持续时间的增加而降低，并且在暴露于100 mg/L硫酸铜8 h后完全丧失。结果表明，硫酸铜对B有较好的抑制作用。木霉菌，并至少部分地通过抑制它们的运动来限制它们对植物的有害影响。
Tan Q.Q., Wu H.Y., Jiang S.X., Ma H.B. (2013): Mortality and movement behaviour of Bursaphelenchus xylophilus under different dosages of copper sulphate. Plant Protect. Sci., 49: 98-103. The effects of in vitro exposure to different concentrations of copper sulphate for different durations on the mortality and locomotor behaviour of Bursaphelenchus xylophilus were evaluated. Copper sulphate showed strong effects against the nematode B. xylophilus at a low concentration (5 mg/l). The median lethal concentration (LC 50 ) at 8, 24, 48, and 72 h were 31.634, 7.353, 6.557, and 5.568 mg/l, respectively. Mortality rate of B. xylophilus after treatment with various concentrations of copper sulphate for 6, 8, 24, 48, and 72 h were significantly different compared with control animals exposed to distilled water ( P < 0.01). Locomotor activity of the nematodes decreased with increased duration of exposure and was completely lost after 8 h of exposure to 100 mg/l copper sulphate. Our results indicate that copper sulphate is effective against B. xylophilus and restricts their harmful effects on plants at least in part by inhibiting their movement.
