Laboratory experiments were performed to investigate the ability of isolates from the predacious fungus species Arthrobotrys conoides (one isolate) and Al. robusta (four isolates) to trap and kill infective Haemonchus placei larvae. Three groups for each isolate were formed: group 1, fungi and infective larvae; group 2, fungi; group 3, infective larvae. There were statistically significant differences (P < 0.05) between the antagonistic effects of three isolates of A. robusta, but there was no such difference between the isolate of A. conoides and isolates of A. robusta. This result indicates that there can be a variation in the predatory capacity of different isolates within a single fungus species. After 20 days of assay, there was greater recuperation of infective H. placei larvae in group 3 compared to group 1.
进行了实验室实验，以研究从捕食性真菌类圆锥节丛孢菌（1个分离株）和粗壮节丛孢菌（4个分离株）中分离出的菌株捕获并杀死感染性捻转血矛线虫幼虫的能力。每个分离株都分为三组：第1组，真菌和感染性幼虫；第2组，真菌；第3组，感染性幼虫。粗壮节丛孢菌的三个分离株的拮抗作用之间存在统计学显著差异（P < 0.05），但圆锥节丛孢菌的分离株与粗壮节丛孢菌的分离株之间不存在这种差异。这一结果表明，同一真菌物种内不同分离株的捕食能力可能存在差异。在测定20天后，与第1组相比，第3组中感染性捻转血矛线虫幼虫的恢复情况更好。
